1 00:00:00,759 --> 00:00:08,600 Dan Suiter: Welcome everybody. So I am going to talk a little bit about cockroaches today. Some of this is, 2 00:00:10,820 --> 00:00:14,420 Dan Suiter: it's in parts of this you've, some of you have probably seen before, but it's worth, 3 00:00:14,920 --> 00:00:17,600 Dan Suiter: it's worth reiterating some of the information I'm going to talk about 4 00:00:18,860 --> 00:00:22,920 Dan Suiter: on some of the biology of some of these critters. And it's, this is mainly talk about the, 5 00:00:24,040 --> 00:00:29,980 Dan Suiter: we'll concentrate a little bit on German cockroaches, but it's mainly a more of a 6 00:00:29,300 --> 00:00:33,360 Dan Suiter: a large breadth of cockroaches of the southeastern US. 7 00:00:34,100 --> 00:00:36,399 Dan Suiter: And most of what we're gonna talk about here, 8 00:00:36,550 --> 00:00:38,600 Dan Suiter: the larger peridomestic cockroaches 9 00:00:39,140 --> 00:00:40,420 Dan Suiter: have a worldwide distribution. 10 00:00:40,640 --> 00:00:42,379 Dan Suiter: So if you're a little bit further north, 11 00:00:43,210 --> 00:00:44,680 Dan Suiter: you may not have the 12 00:00:45,800 --> 00:00:50,180 Dan Suiter: the diversity of cockroach species that we have down here in Georgia. 13 00:00:50,980 --> 00:00:51,780 Dan Suiter: Lucky you, I guess. 14 00:00:52,300 --> 00:00:57,300 Dan Suiter: But you have some of the more pest species. 15 00:00:58,699 --> 00:01:01,699 Dan Suiter: Interestingly, there are about 5,000 cockroach species worldwide. 16 00:01:02,100 --> 00:01:10,880 Dan Suiter: And of course, Florida, there was a review of the cockroaches of the United States published several years ago by Tom Atkinson. 17 00:01:11,540 --> 00:01:17,000 Dan Suiter: If you just search cockroaches of the US, there was a nice little bulletin that came up. 18 00:01:18,600 --> 00:01:21,540 Dan Suiter: the Entomological Society of America published this thing, 19 00:01:21,600 --> 00:01:23,820 Dan Suiter: and it was a distribution of all the cockroach species 20 00:01:23,880 --> 00:01:24,500 Dan Suiter: in the US. 21 00:01:25,200 --> 00:01:27,259 Dan Suiter: And of course, Florida had double the amount 22 00:01:28,000 --> 00:01:29,619 Dan Suiter: that any other state had. 23 00:01:30,280 --> 00:01:32,820 Dan Suiter: And the further north and the further west you went, 24 00:01:32,900 --> 00:01:34,740 Dan Suiter: the number of species kind of dropped off. 25 00:01:35,259 --> 00:01:38,340 Dan Suiter: But so yeah, the Southeast is like that, 26 00:01:38,540 --> 00:01:40,240 Dan Suiter: you could say the same thing about ants. 27 00:01:40,400 --> 00:01:44,540 Dan Suiter: and lots of other critters that are dealt with by the pest control industry in the south and southeast, 28 00:01:45,260 --> 00:01:52,720 Dan Suiter: because of our abundant rainfall and warm temperatures, you know, we have more bugs than most other people. 29 00:01:54,220 --> 00:01:56,800 Dan Suiter: But one of the things I wanted to, before I got going on that, 30 00:01:58,000 --> 00:02:01,540 Dan Suiter: I promised some folks at the Entomological Society of America 31 00:02:03,320 --> 00:02:05,660 Dan Suiter: that I would talk a little bit about their credentialing program. 32 00:02:06,700 --> 00:02:13,239 Dan Suiter: My professional society is called the Entomological Society of America, and it's been in existence, 33 00:02:15,220 --> 00:02:21,280 Dan Suiter: 1800s. It's a, it's a really old organization. And it's one time a year they get together, 34 00:02:22,260 --> 00:02:26,780 Dan Suiter: and people share their research and anything that's insect related. 35 00:02:26,780 --> 00:02:31,700 Dan Suiter: And these are people from almost all universities in the US. 36 00:02:33,840 --> 00:02:42,519 Dan Suiter: you know, industry and it's just a number of people get together. Well, this year it was a hybrid virtual and 37 00:02:44,280 --> 00:02:50,200 Dan Suiter: face to face. We did not meet last year, but this year was in Denver last week and I went and 38 00:02:51,579 --> 00:03:01,519 Dan Suiter: One of the things that was being talked about was a new program called the CIT. I'm going to talk about CIT in just a minute, but it's strictly for pest control technicians. It's why they developed this. 39 00:03:02,520 --> 00:03:09,180 Dan Suiter: Many of you are probably aware of the ACE program and I'll talk a little bit about the ACE program, 40 00:03:09,280 --> 00:03:15,180 Dan Suiter: the Associate Certified Entomologist program. There's also an ACE International, so we may have 41 00:03:15,260 --> 00:03:19,900 Dan Suiter: some folks in Canada that are listening right now. We have several people that participate 42 00:03:20,080 --> 00:03:23,780 Dan Suiter: from Canada every month, but there's an ACE and an ACE International. 43 00:03:24,300 --> 00:03:27,540 Dan Suiter: There's a board certified entomologist, which are for, 44 00:03:28,760 --> 00:03:31,920 Dan Suiter: that's a certification for people 45 00:03:32,020 --> 00:03:34,040 Dan Suiter: who are degreed entomologists, right? 46 00:03:34,040 --> 00:03:37,420 Dan Suiter: So you can up your game a little bit 47 00:03:37,500 --> 00:03:39,160 Dan Suiter: by becoming a board certified entomologist, 48 00:03:39,200 --> 00:03:41,460 Dan Suiter: just like any other profession, you become board certified. 49 00:03:42,020 --> 00:03:44,800 Dan Suiter: And then just last week on November 2nd, 50 00:03:45,100 --> 00:03:52,440 Dan Suiter: The ESA unveiled a program called the Certified IPM Technician, and this is strictly for pest control technicians. 51 00:03:53,180 --> 00:04:00,920 Dan Suiter: So the ACE program was meant mainly as a credential for, in Georgia, for instance, it would be a certified operator. 52 00:04:01,680 --> 00:04:08,180 Dan Suiter: And people that are in a, have had five years, just to sit for the exam for the ACE, I think you have to have five years of experience. 53 00:04:08,600 --> 00:04:17,060 Dan Suiter: So, it does not exclude technicians, but this new program, the certified IPM technician, 54 00:04:17,220 --> 00:04:21,459 Dan Suiter: the CIT program, is specifically for technicians to try to allow, 55 00:04:21,940 --> 00:04:25,540 Dan Suiter: to provide technicians a credential, a new credential. 56 00:04:25,700 --> 00:04:28,900 Dan Suiter: It's credentials that come from the Entomological Society of America. 57 00:04:29,140 --> 00:04:32,020 Dan Suiter: And then there's another one called the Public Health Entomology Certificate. 58 00:04:32,300 --> 00:04:36,800 Dan Suiter: So the ACE, the Associate Certified Entomologist Program, 59 00:04:38,060 --> 00:04:39,419 Dan Suiter: started back in 2004. 60 00:04:39,460 --> 00:04:41,819 Dan Suiter: There are probably some people that are here listening right now. 61 00:04:42,419 --> 00:04:45,080 Dan Suiter: If you're an ACE, it's a feather in your cap. 62 00:04:45,080 --> 00:04:46,919 Dan Suiter: There are only 1,300 of them globally. 63 00:04:47,840 --> 00:04:50,919 Dan Suiter: So if you're an ACE, you know that you studied really, really hard 64 00:04:51,020 --> 00:04:54,800 Dan Suiter: to get that certification. 65 00:05:01,319 --> 00:05:02,280 Dan Suiter: It's a... 66 00:04:56,500 --> 00:05:03,360 Dan Suiter: It's a bear, and it's a bear to study for and to pass. 67 00:05:03,440 --> 00:05:07,080 Dan Suiter: I think they may have reduced the number 68 00:05:07,240 --> 00:05:09,080 Dan Suiter: of continuing education hours 69 00:05:09,120 --> 00:05:10,260 Dan Suiter: that are required to keep your ACE, 70 00:05:10,620 --> 00:05:13,040 Dan Suiter: but it's still a pretty rigorous program. 71 00:05:14,800 --> 00:05:17,360 Dan Suiter: Eligibility is based on your experience. 72 00:05:17,360 --> 00:05:19,320 Dan Suiter: I think it's five years and then some of your life. 73 00:05:19,460 --> 00:05:21,040 Dan Suiter: Of course, you have to be licensed in your state. 74 00:05:22,400 --> 00:05:26,000 Dan Suiter: Of course, the international program was launched in 2014. 75 00:05:26,940 --> 00:05:29,220 Dan Suiter: And NPMA is, this is a, 76 00:05:29,860 --> 00:05:32,300 Dan Suiter: not just the ESA worked with NPMA 77 00:05:32,440 --> 00:05:34,240 Dan Suiter: to help develop this program. 78 00:05:34,840 --> 00:05:38,180 Dan Suiter: And then last week or back in November 1st, 79 00:05:39,539 --> 00:05:41,880 Dan Suiter: on Monday, it was a week ago, Monday, 80 00:05:43,000 --> 00:05:48,120 Dan Suiter: The first, the newest ESA credential was launched and it was aimed at those 81 00:05:48,860 --> 00:05:54,080 Dan Suiter: pest control technicians who are just maybe just starting in their career or have been a technician for 82 00:05:54,780 --> 00:06:00,300 Dan Suiter: you know six, seven, eight, ten years and want to acquire some type of credential to advance themselves. 83 00:06:01,100 --> 00:06:07,220 Dan Suiter: There's no licensing requirements other than your local pesticide application, so you have to be registered. 84 00:06:07,870 --> 00:06:09,700 Dan Suiter: In Georgia, you'd have to be a registered technician. 85 00:06:11,639 --> 00:06:16,199 Dan Suiter: There's an exam and there are CEUs that have to be acquired. 86 00:06:16,699 --> 00:06:20,759 Dan Suiter: So if you look at this across the top here, here's the ACE program. 87 00:06:21,380 --> 00:06:24,540 Dan Suiter: So, requires a license of course. 88 00:06:26,000 --> 00:06:34,740 Dan Suiter: and the CIT does not. Years of experience, five for the ACE, just one for the CIT for technicians. 89 00:06:36,260 --> 00:06:42,440 Dan Suiter: And then exam is required, exam and CEUs are required for the ACE program and for the CIT 90 00:06:42,800 --> 00:06:48,220 Dan Suiter: program. So if you want more information about this for your technicians, I'd love to see. 91 00:06:49,199 --> 00:06:57,060 Dan Suiter: Frankly, I'd love to see Georgia lead the country in both ACEs and CIT people.

If you give an American cockroach water, but you don't give it any food to eat, it can live three months. 125 00:09:37,300 --> 00:09:41,120 Dan Suiter: And when I talk about this, I say, you know, that's bed bug territory. 126 00:09:41,100 --> 00:09:46,120 Dan Suiter: You know, bed bugs can live two or three months without a blood meal. 127 00:09:46,680 --> 00:09:54,519 Dan Suiter: And it makes them just go into some type of torpor, and they go into a, just an inactive stage. 128 00:09:56,300 --> 00:10:00,959 Dan Suiter: Bedbugs do when they don't have food, and that causes them to move in search of food, right? 129 00:10:01,300 --> 00:10:03,459 Dan Suiter: But they can go months. 130 00:10:03,740 --> 00:10:06,279 Dan Suiter: This is a problem, right? 131 00:10:06,459 --> 00:10:07,800 Dan Suiter: So if somebody moves out of an apartment, 132 00:10:08,680 --> 00:10:09,839 Dan Suiter: you won't starve them out. 133 00:10:10,000 --> 00:10:11,399 Dan Suiter: You're not gonna starve out bed bugs. 134 00:10:11,519 --> 00:10:13,820 Dan Suiter: And apparently you're not gonna starve out cockroaches 135 00:10:13,959 --> 00:10:14,100 Dan Suiter: either. 136 00:10:15,779 --> 00:10:18,560 Dan Suiter: So by just giving them water. 137 00:10:18,899 --> 00:10:19,459 Dan Suiter: [CLEARS THROAT] 138 00:10:20,000 --> 00:10:29,080 Dan Suiter: So I put this slide in here to remind myself to talk about this whole issue of nitrogen and the system. 139 00:10:30,560 --> 00:10:34,260 Dan Suiter: It's such unique biology for cockroaches that it's... 140 00:10:34,000 --> 00:10:34,640 Dan Suiter: It's- 141 00:10:36,640 --> 00:10:38,840 Dan Suiter: it's worth mentioning over and over again. 142 00:10:39,220 --> 00:10:43,400 Dan Suiter: So, cockroaches are truly really unique creatures. 143 00:10:46,220 --> 00:10:49,300 Dan Suiter: So, when an insect, you know, there are about, 144 00:10:50,040 --> 00:10:53,820 Dan Suiter: I guess, 2 million, maybe 1 million different species 145 00:10:53,880 --> 00:10:56,420 Dan Suiter: of insects that are known to science. 146 00:10:56,810 --> 00:10:57,920 Dan Suiter: If you talk to, 147 00:10:58,160 --> 00:10:59,000 [INAUDIBLE: silence; ASR artifact "Bye."] 148 00:10:59,500 --> 00:11:06,580 Dan Suiter: If you talk to entomologists, they'll tell you, people that go down and look for new 149 00:11:06,620 --> 00:11:10,260 Dan Suiter: species of insects, they go to the most remote parts of the world. 150 00:11:10,580 --> 00:11:14,840 Dan Suiter: Every time they go down there, they find new species of insects that are new to science. 151 00:11:15,100 --> 00:11:25,579 Dan Suiter: And so they'll tell you that their estimate is that we know of 1 million, there are probably 3 to 5 million species of insects on the globe. 152 00:11:26,540 --> 00:11:30,860 Dan Suiter: That most of the insects, most of the insect species are not known. 153 00:11:32,959 --> 00:11:35,339 Dan Suiter: A couple years ago, I was 154 00:11:36,860 --> 00:11:39,519 Dan Suiter: conducting a study of the ants of Brunswick, Georgia. 155 00:11:39,880 --> 00:11:43,600 Dan Suiter: We're just going into local parks, collecting ant species. 156 00:11:44,019 --> 00:11:47,019 Dan Suiter: And I didn't know that much about identifying them. 157 00:11:47,019 --> 00:11:50,060 Dan Suiter: I had to work with somebody in Gainesville, Florida to identify them. 158 00:11:50,100 --> 00:11:54,199 Dan Suiter: And I sent him a sample, and this is in a local park in Brunswick, Georgia. 159 00:11:54,600 --> 00:11:59,040 Dan Suiter: I collected one that he said did not have a scientific name. 160 00:11:59,069 --> 00:12:00,819 Dan Suiter: It was not known to science. 161 00:12:01,360 --> 00:12:03,360 Dan Suiter: So here was something right underneath people's feet 162 00:12:04,420 --> 00:12:07,120 Dan Suiter: that was an ant species in a particular genus 163 00:12:07,720 --> 00:12:10,279 Dan Suiter: that had never been collected, never found, and never described. 164 00:12:10,940 --> 00:12:13,399 Dan Suiter: So the point I'm trying to make here is that 165 00:12:13,759 --> 00:12:15,920 Dan Suiter: the diversity of insects is really, really large. 166 00:12:16,480 --> 00:12:17,480 Dan Suiter: And they're mostly tropical. 167 00:12:23,699 --> 00:12:24,579 Dan Suiter: Cockroaches are 168 00:12:20,680 --> 00:12:23,319 Dan Suiter: cockroaches are really tropical. They're right along the equator. 169 00:12:23,740 --> 00:12:29,100 Dan Suiter: So, they're a few degrees on either side of the equator is where your abundance of cockroaches are. 170 00:12:29,899 --> 00:12:35,220 Dan Suiter: And so, they live in these really highly tropical rainforest type areas. 171 00:12:37,139 --> 00:12:43,259 Dan Suiter: And insects in general, when they feed on something, when they eat something, 172 00:12:43,500 --> 00:12:48,700 Dan Suiter: you've got to take in nutrients. And one of the nutrients, of course, is nitrogen. 173 00:12:49,700 --> 00:13:00,100 Dan Suiter: Right? So, nitrogen is used to make proteins. So, when your body is your body, and an insect's body 174 00:13:00,700 --> 00:13:05,060 Dan Suiter: is synthesizing proteins, they have to use nitrogen to make that protein. 175 00:13:05,760 --> 00:13:11,140 Dan Suiter: Well, insects take in more nitrogen than they can actually use at that moment. 176 00:13:11,600 --> 00:13:15,899 Dan Suiter: So, it comes out the other end and they get rid of it. 177 00:13:16,600 --> 00:13:22,920 Dan Suiter: As in a form of a chemical called uric acid and it has a white look to it. 178 00:13:23,040 --> 00:13:27,079 Dan Suiter: It's a, think of a bird poop, you know, the white bird poop that you see, that's uric acid. 179 00:13:27,160 --> 00:13:28,779 Dan Suiter: The white is bird poop. 180 00:13:29,279 --> 00:13:38,240 Dan Suiter: So, insects excrete, they excrete their excess nitrogen as uric acid, except cockroaches. 181 00:13:40,400 --> 00:13:44,400 Dan Suiter: cockroaches actually hold on to that excess nitrogen. 182 00:13:44,680 --> 00:13:47,460 Dan Suiter: So if they're in an environment where, 183 00:13:49,150 --> 00:13:52,900 Dan Suiter: you know, they're in a big forest, 184 00:13:53,230 --> 00:13:55,920 Dan Suiter: big tropical rainforest where they can't fly, 185 00:13:56,280 --> 00:13:57,680 Dan Suiter: they're crawling around on the forest floor, 186 00:13:57,760 --> 00:13:58,900 Dan Suiter: they're crawling around the trees, 187 00:13:59,340 --> 00:14:01,220 Dan Suiter: there's not a lot of nitrogen for them to eat. 188 00:14:01,460 --> 00:14:03,200 Dan Suiter: Nitrogen comes in the form of dead animals. 189 00:14:03,500 --> 00:14:13,180 Dan Suiter: So, a dead bat, a dead bird, a dead lizard, whatever it might be, those dead things are rare. 190 00:14:13,900 --> 00:14:19,760 Dan Suiter: So if you're a cockroach living on the forest floor and you're eating dead leaves and fungi and stuff like that, you don't have a whole lot of nitrogen sources. 191 00:14:20,320 --> 00:14:23,080 Dan Suiter: So when one does come by and you eat it, 192 00:14:23,500 --> 00:14:26,040 Dan Suiter: and you utilize the nitrogen at that moment, 193 00:14:26,800 --> 00:14:28,760 Dan Suiter: don't get rid of the rest of it, keep it. 194 00:14:29,440 --> 00:14:30,520 Dan Suiter: So that's what they do. 195 00:14:30,720 --> 00:14:32,860 Dan Suiter: And this is, cockroaches are unique in doing this. 196 00:14:32,900 --> 00:14:34,500 Dan Suiter: They, no other insect does this. 197 00:14:35,000 --> 00:14:38,160 Dan Suiter: They store it and they store it as fat. 198 00:14:39,140 --> 00:14:39,440 Dan Suiter: So. 199 00:14:40,500 --> 00:14:50,800 Dan Suiter: The best recollection you might have of fat body in a cockroach is when you step on an American roach, that white stuff that comes out, that's all uric acid. 200 00:14:51,660 --> 00:14:53,840 Dan Suiter: And that is gold to a cockroach. 201 00:14:55,000 --> 00:15:01,120 Dan Suiter: So, what they do is they'll, there's multiple, there's three different cell types in a fat body. 202 00:15:02,060 --> 00:15:03,640 Dan Suiter: And one is called a urocyte. 203 00:15:05,620 --> 00:15:09,460 Dan Suiter: CYT just means cell and uro means uric acid. 204 00:15:09,920 --> 00:15:11,340 Dan Suiter: There's a cell called a urocyte 205 00:15:11,860 --> 00:15:15,120 Dan Suiter: that this excess nitrogen is made into uric acid 206 00:15:15,180 --> 00:15:19,940 Dan Suiter: and it goes into this cell and it's stored in that cell. 207 00:15:20,740 --> 00:15:24,880 Dan Suiter: Right next to it is another cell called a mycetocyte. 208 00:15:25,340 --> 00:15:29,860 Dan Suiter: And that is a cell that only stores bacteria. 209 00:15:30,400 --> 00:15:36,720 Dan Suiter: And this is a species of bacteria that's found in cockroach gut in nowhere else on the globe. 210 00:15:36,980 --> 00:15:39,280 Dan Suiter: It's only found in a cockroach gut. 211 00:15:39,900 --> 00:15:46,340 Dan Suiter: So when the cockroach starts becoming starved, it has to utilize the nitrogen that's tied up as uric acid. 212 00:15:46,900 --> 00:15:52,520 Dan Suiter: This bacteria goes in and breaks down the uric acid into usable nitrogen, 213 00:15:53,360 --> 00:15:55,720 Dan Suiter: and the cockroach can then survive starvation. 214 00:15:56,980 --> 00:16:01,000 Dan Suiter: That's why they can go live three months without, without just giving them water. 215 00:16:01,370 --> 00:16:03,140 Dan Suiter: They can go three months without starvation. 216 00:16:03,940 --> 00:16:05,900 Dan Suiter: This is a system that... 217 00:16:05,900 --> 00:16:06,000 [INAUDIBLE: silence; ASR artifact "Bye-bye."] 218 00:16:07,000 --> 00:16:09,200 Dan Suiter: is what we call obligatory. 219 00:16:09,800 --> 00:16:13,160 Dan Suiter: So cockroach cannot, they can't stop this system. 220 00:16:14,020 --> 00:16:15,740 Dan Suiter: There were studies, we did it too. 221 00:16:16,880 --> 00:16:17,940 Dan Suiter: There were studies that were published 222 00:16:18,040 --> 00:16:20,200 Dan Suiter: that if you give a cockroach a high protein diet 223 00:16:21,280 --> 00:16:23,060 Dan Suiter: in a kitchen, they're not really eating, 224 00:16:23,900 --> 00:16:26,000 Dan Suiter: they may be eating a piece of chicken that's high protein, 225 00:16:26,120 --> 00:16:29,020 Dan Suiter: food, fish, that kind of thing, steak, that's high protein. 226 00:16:29,080 --> 00:16:30,320 Dan Suiter: But a lot of it is just grease. 227 00:16:30,700 --> 00:16:34,300 Dan Suiter: And they're forging for, German cockroaches are forging for something. 228 00:16:34,930 --> 00:16:38,740 Dan Suiter: But if you give them a really high protein diet and nothing else, 229 00:16:41,420 --> 00:16:44,060 Dan Suiter: they're obligated to make uric acid. 230 00:16:44,060 --> 00:16:49,560 Dan Suiter: They can't stop the process to the point that their gut almost explodes. 231 00:16:50,000 --> 00:16:52,800 Dan Suiter: with uric acid, that they're trying to pack 232 00:16:52,900 --> 00:16:53,920 Dan Suiter: that uric acid in there. 233 00:16:54,280 --> 00:16:55,920 Dan Suiter: They're eating a high protein food. 234 00:16:56,300 --> 00:16:57,700 Dan Suiter: They actually can't stop. 235 00:16:57,820 --> 00:16:58,660 Dan Suiter: They can't stop it. 236 00:16:59,320 --> 00:17:02,240 Dan Suiter: And their gut, their gut nearly explodes 237 00:17:02,380 --> 00:17:04,319 Dan Suiter: because there's so much uric acid in there. 238 00:17:06,600 --> 00:17:09,480 Dan Suiter: When I was in Florida, we worked on a, 239 00:17:10,600 --> 00:17:12,120 Dan Suiter: there's a human connection here. 240 00:17:13,939 --> 00:17:15,980 Dan Suiter: And I talk about this every time I talk 241 00:17:16,039 --> 00:17:17,240 Dan Suiter: about this uric acid system, 242 00:17:17,439 --> 00:17:20,179 Dan Suiter: because there's a connection between cockroaches and you. 243 00:17:21,600 --> 00:17:24,020 Dan Suiter: And if there's somebody listening out there 244 00:17:24,100 --> 00:17:25,280 Dan Suiter: that's ever had gout, 245 00:17:26,000 --> 00:17:28,380 Dan Suiter: you know that gout is uric acid. 246 00:17:29,480 --> 00:17:34,420 Dan Suiter: The way you make your uric acid in your blood is the same way 247 00:17:35,040 --> 00:17:38,640 Dan Suiter: cockroaches make uric acid in their body. 248 00:17:42,520 --> 00:17:45,140 Dan Suiter: If you have a molecule of uric acid here, 249 00:17:45,190 --> 00:17:46,620 Dan Suiter: it was something before that. 250 00:17:46,900 --> 00:17:54,000 Dan Suiter: Right. And so that whatever it was before that is called a precursor to uric acid. 251 00:17:54,840 --> 00:18:02,000 Dan Suiter: So there's a there's an enzyme that actually converts that precursor into uric acid. 252 00:18:02,960 --> 00:18:03,280 Dan Suiter: So. 253 00:18:03,280 --> 00:18:04,380 [INAUDIBLE: silence; ASR artifact "Thank you."] 254 00:18:06,000 --> 00:18:11,299 Dan Suiter: drugs, a human drug is meant to remove that enzyme. 255 00:18:11,820 --> 00:18:15,700 Dan Suiter: So it used to be, there was a drug called allopurinol 256 00:18:16,340 --> 00:18:18,059 Dan Suiter: and it was a pill that you took 257 00:18:18,200 --> 00:18:19,580 Dan Suiter: and you absorbed it into your blood. 258 00:18:20,080 --> 00:18:21,880 Dan Suiter: And what it did was it took that enzyme, 259 00:18:21,960 --> 00:18:24,880 Dan Suiter: the allopurinol came in and grabbed that enzyme 260 00:18:25,020 --> 00:18:29,160 Dan Suiter: from the system and it removed that enzyme from the system 261 00:18:29,500 --> 00:18:31,600 Dan Suiter: and it prevented the buildup of uric acid. 262 00:18:31,760 --> 00:18:34,400 Dan Suiter: As you know, uric acid is a buildup of... 263 00:18:34,200 --> 00:18:39,019 Dan Suiter: of, it's, well, gout is a buildup of uric acid 264 00:18:39,100 --> 00:18:40,340 Dan Suiter: into knife-like slivers, 265 00:18:40,840 --> 00:18:43,519 Dan Suiter: and they concentrate around your toes and your ankles, 266 00:18:44,480 --> 00:18:46,480 Dan Suiter: and it's really, really painful. 267 00:18:47,700 --> 00:18:50,100 Dan Suiter: And so when you take this blood, you take this. 268 00:18:50,700 --> 00:18:57,620 Dan Suiter: This allopurinol pill removes the enzyme from the system and you have precursors that build up and PML. [VERIFY: "PML"] 269 00:18:58,279 --> 00:19:01,380 Dan Suiter: And you don't have any more uric acid. 270 00:19:02,240 --> 00:19:07,559 Dan Suiter: We did the same, we gave that same drug, allopurinol, to cockroaches and it killed them. 271 00:19:08,600 --> 00:19:16,799 Dan Suiter: Because we had this, there was no more uric acid buildup, but those precursors built up to toxic levels that the cockroaches had never experienced before. 272 00:19:17,120 --> 00:19:24,600 Dan Suiter: Now it took a long time to do this, but it actually killed them, and the University of Florida patented that use of a human drug for cockroach control. 273 00:19:25,000 --> 00:19:28,620 Dan Suiter: And it turned out it was too slow. 274 00:19:28,880 --> 00:19:29,900 Dan Suiter: It was just way too slow. 275 00:19:29,960 --> 00:19:31,980 Dan Suiter: There's a couple, there was one commercialized bait 276 00:19:32,480 --> 00:19:34,880 Dan Suiter: that had oxypurinol as the active ingredient. 277 00:19:35,100 --> 00:19:36,420 Dan Suiter: Some of you have been in the industry a long time, 278 00:19:36,540 --> 00:19:37,220 Dan Suiter: might remember this. 279 00:19:37,660 --> 00:19:39,860 Dan Suiter: Long time ago, it was a bait that had oxypurinol, 280 00:19:39,960 --> 00:19:42,400 Dan Suiter: but it took, it's like a growth regulator. 281 00:19:42,600 --> 00:19:45,660 Dan Suiter: It takes months and months and months to get a reduction. 282 00:19:45,900 --> 00:19:47,720 Dan Suiter: But in the trials that we did, 283 00:19:48,700 --> 00:19:58,460 Dan Suiter: It prevented, it took a long time, but cockroaches that ate bait laced with allopurinol saw a major reduction in their numbers. 284 00:19:58,720 --> 00:20:05,679 Dan Suiter: So, I told you I was going to cover this, I probably spent too much time on it, but it's really cool stuff. 285 00:20:05,899 --> 00:20:08,779 Dan Suiter: Cockroaches are the ultimate cool insect. 286 00:20:08,779 --> 00:20:12,500 Dan Suiter: They are, some of them are pretty gross, 287 00:20:12,700 --> 00:20:14,539 Dan Suiter: but I'm gonna show you some pictures here 288 00:20:14,539 --> 00:20:15,899 Dan Suiter: in a little bit of some that are. 289 00:20:18,380 --> 00:20:21,240 Dan Suiter: quite attractive. They're strikingly pretty. 290 00:20:23,340 --> 00:20:26,000 Dan Suiter: And there's an article, I talked about this too, 291 00:20:26,400 --> 00:20:28,720 Dan Suiter: there's an article published years ago, I want to get it, I can't remember, 292 00:20:30,260 --> 00:20:34,280 Dan Suiter: I'm going to have to see if I can get it online, but it was National Geographic, it was cockroaches of the world. 293 00:20:34,600 --> 00:20:45,480 Dan Suiter: And some of the cockroaches and some of the images of the roaches in that publication were every bit as beautiful as any, any swallowtail butterfly you'd ever seen. 294 00:20:45,620 --> 00:20:51,600 Dan Suiter: There are some really incredible looking cockroaches. Some really nasty ones too, when we deal with those. 295 00:20:52,200 --> 00:21:04,580 Dan Suiter: So, I'm going to talk a little bit about peridomestic cockroaches here. I don't know how far I'll get here, but we'll, we'll take a break close to four o'clock and then 296 00:21:03,520 --> 00:21:05,020 Dan Suiter: We'll start talking about ants. 297 00:21:05,120 --> 00:21:07,380 Dan Suiter: But, peridomestic cockroaches, 298 00:21:07,480 --> 00:21:08,740 Dan Suiter: or anything that's big, right? 299 00:21:08,860 --> 00:21:10,760 Dan Suiter: So this is, if you're from the South, 300 00:21:10,840 --> 00:21:12,240 Dan Suiter: or from, especially from Florida, 301 00:21:12,340 --> 00:21:13,340 Dan Suiter: you're called a palmetto bug. 302 00:21:13,880 --> 00:21:15,400 Dan Suiter: There truly is a palmetto bug. 303 00:21:15,700 --> 00:21:18,540 Dan Suiter: There is a cockroach that has a common name, 304 00:21:18,560 --> 00:21:19,780 Dan Suiter: it's called palmetto bug. 305 00:21:20,420 --> 00:21:23,020 Dan Suiter: And it's Eurycotis floridana, a Florida woods roach. 306 00:21:24,200 --> 00:21:26,179 Dan Suiter: It looks like a UGA linebacker. 307 00:21:26,340 --> 00:21:30,260 Dan Suiter: This thing is that big, it's wingless, and it has weight. 308 00:21:30,700 --> 00:21:32,019 Dan Suiter: It lives in palm trees. 309 00:21:34,440 --> 00:21:39,019 Dan Suiter: And they have this chemical defensive compound 310 00:21:39,100 --> 00:21:40,039 Dan Suiter: that they spray. 311 00:21:41,299 --> 00:21:43,260 Dan Suiter: When you really irritate them, they'll spray it. 312 00:21:43,299 --> 00:21:44,500 Dan Suiter: I mean, they'll spray it at a distance 313 00:21:44,559 --> 00:21:46,299 Dan Suiter: and it's a really pungent odor 314 00:21:46,399 --> 00:21:47,440 Dan Suiter: and you have to leave the room. 315 00:21:49,000 --> 00:21:53,260 Dan Suiter: was to trap these things and it would have a show the trap here in just a few minutes. 316 00:21:53,640 --> 00:21:58,600 Dan Suiter: There was a one quart paint can and we would trap them to see how well our treatments worked or 317 00:21:58,700 --> 00:22:05,780 Dan Suiter: whatever. And every time we would get these things in, raccoons would find these traps and eat all 318 00:22:05,800 --> 00:22:10,740 Dan Suiter: the cockroaches and they would never ever eat one of these smoky, one of these large palmetto 319 00:22:12,040 --> 00:22:16,300 Dan Suiter: bug roaches, the Florida woods roach, because they would bite into this thing and we would get 320 00:22:16,200 --> 00:22:17,300 Dan Suiter: roaches back that would have 321 00:22:17,700 --> 00:22:25,840 Dan Suiter: fang marks where the raccoon had bit into the cockroach and got a mouthful of yuck from the roach and spit it out. 322 00:22:26,700 --> 00:22:31,539 Dan Suiter: But this is, you only find these in Florida. It's a Florida woods roach, big old honking thing. 323 00:22:33,299 --> 00:22:40,260 Dan Suiter: But in large part, these peridomestic roaches, the large roaches, basically the non-German roaches, 324 00:22:40,600 --> 00:22:49,360 Dan Suiter: They live a long time. They'll live a year, right? So, they may live six to nine months as an adult. 325 00:22:49,840 --> 00:22:55,919 Dan Suiter: And it may have taken nine months to get to become an adult. So, this is a long-lived insect. 326 00:22:56,100 --> 00:22:58,660 Dan Suiter: It may be a year and a half to two years old as an insect. 327 00:23:00,300 --> 00:23:06,280 Dan Suiter: Their eggs are protected in an egg case. You'll know them as a, you've called it an ootheca. It's in the egg pouch. 328 00:23:06,580 --> 00:23:10,940 Dan Suiter: You've all, everybody has seen that egg case. They produce one a week. 329 00:23:11,220 --> 00:23:14,840 Dan Suiter: So when a, when one of these large roaches becomes an adult, they mate. 330 00:23:15,340 --> 00:23:21,680 Dan Suiter: They got to mate one time. This is a, it's another common thread in biology of roaches and some moth species, 331 00:23:21,880 --> 00:23:25,460 Dan Suiter: especially Indianmeal moth in German roaches. You got to mate one time. 332 00:23:26,000 --> 00:23:29,360 Dan Suiter: They've got to mate one time to produce all the eggs they'll ever make. 333 00:23:29,490 --> 00:23:32,860 Dan Suiter: They don't have to mate every time they produce eggs like vertebrates do. 334 00:23:33,760 --> 00:23:37,920 Dan Suiter: Of course, they're not active and most common in Georgia, of course, is smoky brown roach. 335 00:23:38,490 --> 00:23:42,820 Dan Suiter: In American roach, smoky brown roach is actually from Japan, originally. 336 00:23:43,520 --> 00:23:47,180 Dan Suiter: And American roach, I think, is from Africa. 337 00:23:48,200 --> 00:23:59,279 Dan Suiter: So, the one thing in common that these cockroaches have is, where you find them harboring, is 338 00:23:59,799 --> 00:24:07,220 Dan Suiter: our environments where the humidity is high, and the air movement is very still, and it's dark. 339 00:24:08,440 --> 00:24:17,680 Dan Suiter: The term blatt, B-L-A-T-T, which is Blattaria, Blattodea, Blattella, that root, B-L-A-T-T, means dark loving. 340 00:24:18,720 --> 00:24:21,620 Dan Suiter: So, when you see roaches, you see them in the dark. 341 00:24:22,220 --> 00:24:22,940 Dan Suiter: Middle of the day. 342 00:24:23,500 --> 00:24:27,820 Dan Suiter: You're not going to see German roaches if you do you probably don't want to go inside. 343 00:24:28,840 --> 00:24:35,900 Dan Suiter: You don't want to hang around, but generally cockroaches come out at nighttime we know this from the work that we do. 344 00:24:37,500 --> 00:24:45,700 Dan Suiter: So, if you look at peridomestic cockroach habitats, it's things like tree holes, attics, crawl spaces, any void. Any. 345 00:24:47,140 --> 00:24:49,580 Dan Suiter: voided block wall, anything of that sort. 346 00:24:50,360 --> 00:24:58,000 Dan Suiter: So, and it's a combination of warm, no wind, and moisture. 347 00:24:58,900 --> 00:25:02,000 Dan Suiter: Right? And that is the definition of an attic with a leak. 348 00:25:02,400 --> 00:25:06,580 Dan Suiter: And in the South, if you have pipes penetrating an attic, 349 00:25:07,500 --> 00:25:08,160 Dan Suiter: you're gonna have a leak. 350 00:25:09,640 --> 00:25:12,460 Dan Suiter: And this is personal experience, but we bought a house, 351 00:25:13,080 --> 00:25:14,020 Dan Suiter: we've been in it 20 years now, 352 00:25:14,100 --> 00:25:18,060 Dan Suiter: but when I bought it about 1957 and did some renovations 353 00:25:18,220 --> 00:25:22,300 Dan Suiter: and it had a major smoky brown cockroach problem. 354 00:25:22,440 --> 00:25:24,260 Dan Suiter: And I can remember going into the... 355 00:25:24,200 --> 00:25:28,059 Dan Suiter: the bathroom and pulling down the drywall, 356 00:25:28,820 --> 00:25:32,480 Dan Suiter: we're gonna redo the drywall in the ceiling 357 00:25:32,480 --> 00:25:34,860 Dan Suiter: and pulled it down and this wave of cockroach, 358 00:25:35,080 --> 00:25:37,100 Dan Suiter: smoky brown cockroach crap came down on me. 359 00:25:37,139 --> 00:25:38,460 Dan Suiter: It was about a half an inch thick. 360 00:25:39,100 --> 00:25:40,539 Dan Suiter: And it was because there was a pipe 361 00:25:40,679 --> 00:25:44,440 Dan Suiter: that penetrated the roof and it leaked, 362 00:25:44,559 --> 00:25:45,720 Dan Suiter: had been leaking for years. 363 00:25:46,340 --> 00:25:47,880 Dan Suiter: And that... 364 00:25:47,700 --> 00:25:50,179 Dan Suiter: Attic was like a big old tree hole. 365 00:25:50,309 --> 00:25:52,220 Dan Suiter: It was a perfect habitat for cockroaches. 366 00:25:52,360 --> 00:25:53,600 Dan Suiter: I finally got up in the attic. 367 00:25:54,159 --> 00:25:55,760 Dan Suiter: This is a picture of my attic here on the left. 368 00:25:57,620 --> 00:25:59,519 Dan Suiter: Redid all the insulation up there and had 369 00:26:00,510 --> 00:26:03,139 Dan Suiter: all those pipes cut off and fix the attic. 370 00:26:03,279 --> 00:26:05,779 Dan Suiter: But a lot of times, smoky brown roach problems indoors. 371 00:26:07,540 --> 00:26:23,680 Dan Suiter: They're living indoors or even if they're living in walls, or a lot of times they'll be living in the attic. So if you can get something in the attic, especially the soffits, the attic itself a lot of times is too hot, but if you have a little bit of air movement in the soffits if you can get 372 00:26:24,500 --> 00:26:28,940 Dan Suiter: granular baits or anything of like that into those areas, that'll work pretty good. 373 00:26:29,460 --> 00:26:31,300 Dan Suiter: These roaches are half starved. 374 00:26:31,500 --> 00:26:33,580 Dan Suiter: Because of that whole uric acid thing, 375 00:26:34,480 --> 00:26:36,220 Dan Suiter: these roaches will eat anything. 376 00:26:38,120 --> 00:26:39,480 Dan Suiter: They're really baitable. 377 00:26:39,720 --> 00:26:43,780 Dan Suiter: These large roaches are any good granular bait, 378 00:26:43,840 --> 00:26:45,980 Dan Suiter: Niban, Advion IG, 379 00:26:46,840 --> 00:26:47,820 Dan Suiter: you can gel bait them, 380 00:26:47,940 --> 00:26:50,620 Dan Suiter: but it's hard to put out the amount of gel. 381 00:26:52,200 --> 00:26:57,380 Dan Suiter: But it's good granular scatter bait for these roaches will do wonders. 382 00:26:57,450 --> 00:26:59,779 Dan Suiter: They do love gel baits too because of the water. 383 00:27:00,600 --> 00:27:03,080 Dan Suiter: But I actually prefer those. 384 00:27:03,549 --> 00:27:08,299 Dan Suiter: A reason I say this is there are a host of parasites that we never see. 385 00:27:08,799 --> 00:27:14,200 Dan Suiter: It's one of these things that you never see these things, but there's a host of parasites and little wasps. 386 00:27:14,400 --> 00:27:17,060 Dan Suiter: that attack the egg capsules of these things. 387 00:27:17,080 --> 00:27:20,920 Dan Suiter: And I did some work in Florida years ago, there's a wasp. 388 00:27:21,100 --> 00:27:22,540 Dan Suiter: It's literally about that big. 389 00:27:23,220 --> 00:27:25,300 Dan Suiter: It's maybe a 16th of an inch. 390 00:27:25,380 --> 00:27:27,540 Dan Suiter: It's like a gnat, like a South Georgian gnat. 391 00:27:29,540 --> 00:27:32,420 Dan Suiter: And the females are actually attracted to the smell. 392 00:27:32,760 --> 00:27:35,260 Dan Suiter: We identified the odor, the chemical 393 00:27:35,820 --> 00:27:37,120 Dan Suiter: that comes off these egg cases. 394 00:27:37,960 --> 00:27:39,840 Dan Suiter: And these wasps will... 395 00:27:39,900 --> 00:27:44,280 Dan Suiter: they'll be attracted from 20 feet away and they'll find that egg case. 396 00:27:44,600 --> 00:27:48,180 Dan Suiter: And if it's in a tree hole, they'll search until they find it. 397 00:27:49,160 --> 00:27:51,120 Dan Suiter: They sting it and they lay 80 eggs in it. 398 00:27:51,580 --> 00:27:54,340 Dan Suiter: That's how small the wasp is. They eat the entire contents. 399 00:27:55,340 --> 00:27:58,140 Dan Suiter: All the baby cockroaches that are in there that are developing. 400 00:27:58,680 --> 00:28:01,620 Dan Suiter: And then they chew a hole in and they all emerge at the same time. 401 00:28:02,040 --> 00:28:04,400 Dan Suiter: They mate and then those females... 402 00:28:04,300 --> 00:28:12,120 Dan Suiter: which are about 80% of the wasps, start looking for additional egg cases to attack. And the study 403 00:28:12,120 --> 00:28:17,940 Dan Suiter: we did in Florida showed about half the egg cases that we recovered were stung by this wasp. 404 00:28:18,920 --> 00:28:21,580 Dan Suiter: So I guess the point I'm trying to make here is... 405 00:28:21,800 --> 00:28:29,360 Dan Suiter: If a bait will work, you know, something like a microcap, pyrethroid microcap would probably work too. 406 00:28:29,560 --> 00:28:36,220 Dan Suiter: So you could spray a wall or, you know, a tree hole, anything of that sort. 407 00:28:36,320 --> 00:28:38,540 Dan Suiter: That's going to work, but it's also going to kill the parasites. 408 00:28:38,700 --> 00:28:44,980 Dan Suiter: And so just by doing something like switching to a granular bait, handfuls of granular bait, 409 00:28:45,659 --> 00:28:50,159 Dan Suiter: and the granule will stay there a long time with a, with a, with a liquid spray. 410 00:28:50,960 --> 00:28:57,320 Dan Suiter: You know, we did some ant trials here this summer and we put out a, we put out a liquid 411 00:28:57,639 --> 00:29:00,760 Dan Suiter: residual two nights later, we got five inches of rain. 412 00:29:02,700 --> 00:29:04,899 Dan Suiter: I'm not sure if anything was there later. 413 00:29:05,480 --> 00:29:09,179 Dan Suiter: But with a bait like that, if it's in a protected environment, you still have bait available 414 00:29:09,299 --> 00:29:09,880 Dan Suiter: for a long time. 415 00:29:09,899 --> 00:29:13,600 Dan Suiter: And keep in mind, when these egg cases hatch, you'll kill a lot of the adults here when 416 00:29:13,600 --> 00:29:18,440 Dan Suiter: you first put out the bait, but these egg capsules incubate for 40 days. 417 00:29:18,799 --> 00:29:23,720 Dan Suiter: And so you, it may be a little while longer, but you're going to get another influx of 418 00:29:24,480 --> 00:29:26,419 Dan Suiter: cockroaches when all these egg capsules hatch. 419 00:29:27,400 --> 00:29:32,760 Dan Suiter: horses, smoky brown roaches from East Asia. You all know what this thing looks like. [VERIFY: "horses"] 420 00:29:33,700 --> 00:29:39,320 Dan Suiter: It's throughout the southeast. I don't think it's ever gotten up into Canada, but another question. 421 00:29:40,240 --> 00:29:42,780 Dan Suiter: And of course, there's the egg caps. Everybody knows what the egg capsule is. 422 00:29:43,200 --> 00:29:47,820 Dan Suiter: Here's our first instar smoky brown cockroach, recently hatched from an ootheca. 423 00:29:48,300 --> 00:29:52,980 Dan Suiter: I put this picture in here because a lot of people don't know what this is. 424 00:29:54,230 --> 00:29:57,320 Dan Suiter: A lot of times they'll carry their, if they're walking, they'll carry their butt up in the air. 425 00:29:57,580 --> 00:30:00,280 Dan Suiter: This thing's about maybe an eighth of an inch long. 426 00:30:00,860 --> 00:30:03,200 Dan Suiter: And they came out of this egg capsule right here. 427 00:30:03,800 --> 00:30:11,060 Dan Suiter: And they got this white band right behind their head, and they have white tips to their antennae. 428 00:30:11,780 --> 00:30:21,920 Dan Suiter: And this is their life. When they hatch from that egg case, these first instars, if you ever find a first instar smoky brown roach or German roach or anything like that, it's hatched within a couple square feet of where you find it. 429 00:30:22,100 --> 00:30:24,660 Dan Suiter: So that's their life. 430 00:30:25,340 --> 00:30:27,440 Dan Suiter: And at least in German roaches, 431 00:30:27,640 --> 00:30:30,340 Dan Suiter: the primary food of German roaches, 432 00:30:30,520 --> 00:30:31,520 Dan Suiter: first instar German roaches, 433 00:30:32,299 --> 00:30:35,059 Dan Suiter: is their mother's fecal matter. 434 00:30:35,660 --> 00:30:39,380 Dan Suiter: So this is why we talk about this domino effect 435 00:30:39,520 --> 00:30:44,120 Dan Suiter: where cockroach will eat a bait and it will die. 436 00:30:44,120 --> 00:30:45,919 Dan Suiter: But before it dies, it poops out. 437 00:30:46,500 --> 00:30:51,700 Dan Suiter: And it has active ingredient in its poop any roach that come to needs that poop will die. 438 00:30:52,520 --> 00:31:02,060 Dan Suiter: And that actually occurs with with German roaches pretty good actually goes another another level with Advion bait so. 439 00:31:03,779 --> 00:31:06,360 Dan Suiter: We may talk about that when we talk about German roaches here in a minute. 440 00:31:09,279 --> 00:31:20,059 Dan Suiter: Yeah, here's a video of some good videos of smoky brown roaches in some of our lab stuff. 441 00:31:20,659 --> 00:31:22,240 Dan Suiter: These are little smoky brown roaches. 442 00:31:22,240 --> 00:31:28,039 Dan Suiter: You see the little white lines there, and that's an American roach there on the lower 443 00:31:28,039 --> 00:31:29,240 Dan Suiter: left is either American roach or a, and there's a big smoky brown cockroach coming in. 444 00:31:35,500 --> 00:31:38,899 Dan Suiter: We talked about tree hole habitats. 445 00:31:39,299 --> 00:31:44,820 Dan Suiter: These, we've got these very common place 446 00:31:44,940 --> 00:31:48,000 Dan Suiter: for smoky brown cockroaches to harbor 447 00:31:48,539 --> 00:31:53,480 Dan Suiter: are these harbor sites where you have these large tree holes 448 00:31:53,919 --> 00:31:55,720 Dan Suiter: and that's the equivalent, basically the equivalent, 449 00:31:55,860 --> 00:31:59,919 Dan Suiter: ecological equivalent of an attic that has a moisture issue. 450 00:32:01,440 --> 00:32:04,080 Dan Suiter: warm, humid, and no air movement. 451 00:32:05,940 --> 00:32:08,500 Dan Suiter: And this was in Athens, this picture right here is in Athens, 452 00:32:08,500 --> 00:32:10,440 Dan Suiter: but everybody, you've got one of these in your yard. 453 00:32:12,360 --> 00:32:16,040 Dan Suiter: And if you go out at nighttime, in July and August, 454 00:32:16,240 --> 00:32:18,380 Dan Suiter: you'll see smoky brown roaches coming out of these things. 455 00:32:18,440 --> 00:32:19,500 Dan Suiter: And that is a... 456 00:32:19,300 --> 00:32:25,120 Dan Suiter: that could very well be a source of of smoky brown cockroaches that maybe are are wandering in 457 00:32:25,460 --> 00:32:33,840 Dan Suiter: from from these things um these tree holes but uh a handful of bait i'm this tree hole right here 458 00:32:35,840 --> 00:32:40,460 Dan Suiter: had a large population of smoky brown at night time 50 roaches that come out of this hole right here 459 00:32:40,800 --> 00:32:46,740 Dan Suiter: And just removing, I'm not a big believer in trying to fill these holes up. 460 00:32:46,800 --> 00:32:49,600 Dan Suiter: People do this to try to make the tree look better or whatever, 461 00:32:49,800 --> 00:32:54,480 Dan Suiter: but all you really do when you do something like that is you create more habitat for roaches. 462 00:32:54,960 --> 00:32:55,640 Dan Suiter: That's all you're doing. 463 00:32:56,200 --> 00:33:02,880 Dan Suiter: And you're actually creating area around that tree hole where more roaches can live 464 00:33:03,040 --> 00:33:05,740 Dan Suiter: because you're creating harborage space. 465 00:33:07,500 --> 00:33:12,560 Dan Suiter: This is at my house when we started redoing some of the fascia boards. 466 00:33:12,970 --> 00:33:18,380 Dan Suiter: This is in the outer area here, the soffits. 467 00:33:19,000 --> 00:33:22,680 Dan Suiter: And you can see that's where the cockroaches go to keep cool, 468 00:33:22,830 --> 00:33:25,140 Dan Suiter: because the internal part of the attic is so hot. 469 00:33:27,160 --> 00:33:38,540 Dan Suiter: any void, right? So any block wall has got voids behind it. There's no such thing as a solid block wall, unless it's poured concrete, of course. 470 00:33:38,960 --> 00:33:53,660 Dan Suiter: But if you've got something like this, you've got granite, you know, that granite is actually probably sitting on a poured wall, or some other, well maybe concrete block that's got screen on it. 471 00:33:54,000 --> 00:34:02,500 Dan Suiter: and this granite has got mud on it and it's put onto the screen and it's hanging on the screen, right? 472 00:34:02,720 --> 00:34:06,620 Dan Suiter: So there's voids all behind this. So at nighttime you go out to this wall right here, 473 00:34:06,830 --> 00:34:12,040 Dan Suiter: you know in the daytime, let's say you go out to this wall and roaches are coming out of every void that's there. 474 00:34:12,480 --> 00:34:17,000 Dan Suiter: And you'll have 150 smoky brown roaches on these steps right here at nighttime. 475 00:34:17,520 --> 00:34:23,040 Dan Suiter: Same with cross ties, rotted cross ties, anything of that sort. 476 00:34:25,339 --> 00:34:37,799 Dan Suiter: Here's a, this is in a local park, and it just looks like a, you know, these blocks are hollow, right, so we would go out we would trap cockroaches at nighttime to bring them back to the lab and do experiments with. 477 00:34:38,619 --> 00:34:39,179 Dan Suiter: But, you know, 478 00:34:39,399 --> 00:34:44,159 Dan Suiter: would go out and you look at this area and it's just full of smoky brown roaches. 479 00:34:44,260 --> 00:34:49,539 Dan Suiter: If you go out here in the daytime and you don't see anything, 480 00:34:50,779 --> 00:34:52,520 Dan Suiter: but you go out here at nighttime and I'll tell you, 481 00:34:52,819 --> 00:34:54,460 Dan Suiter: there's a little bit of a crack right here. 482 00:34:55,279 --> 00:34:58,720 Dan Suiter: That crack right there, a little bit of gel bait, 483 00:35:00,099 --> 00:35:02,279 Dan Suiter: this is backup, a little bit of gel bait, 484 00:35:02,339 --> 00:35:03,680 Dan Suiter: even one of these cracks right here, 485 00:35:04,240 --> 00:35:06,799 Dan Suiter: just a gel, a smear of gel right there, 486 00:35:06,839 --> 00:35:08,640 Dan Suiter: that's where the roaches come out at nighttime. 487 00:35:10,859 --> 00:35:16,819 Dan Suiter: This wall right here, I'll tell you, we would have a hundred, maybe a hundred smoky brown 488 00:35:17,079 --> 00:35:22,460 Dan Suiter: cockroaches coming out of that wall at night time. They're living in the blocks. And just 489 00:35:22,539 --> 00:35:27,599 Dan Suiter: some granular baits. There's another void. Tree holes are, I don't recommend that you do this 490 00:35:28,579 --> 00:35:33,960 Dan Suiter: too often because of, you know, squirrels and probably not raccoons, but maybe possums, 491 00:35:34,079 --> 00:35:39,380 Dan Suiter: things like that could be living in these tree holes. But if you've all seen this, you see a 492 00:35:39,400 --> 00:35:45,079 Dan Suiter: if you could stick your head up in there, this is what you would see, right? There's a big void 493 00:35:45,510 --> 00:35:48,760 Dan Suiter: that goes way up in that tree. This tree is going to fall over at some point. The 494 00:35:49,200 --> 00:35:55,980 Dan Suiter: next big gust of wind is going to die, but the point here is, at nighttime, some smoky 495 00:35:56,079 --> 00:36:02,500 Dan Suiter: brown roaches would come out in a huge population of carpenter ants in that tree right there. 496 00:36:05,820 --> 00:36:21,340 Dan Suiter: Okay, this is the American and brown roach. They're very similar. I'm not going to differentiate between the two here, but the brown cockroach Periplaneta brunnea has slightly different biology than the American cockroach. They are a little bit different. 497 00:36:23,060 --> 00:36:25,440 Dan Suiter: But these are large, these are big roaches, right? 498 00:36:25,599 --> 00:36:28,880 Dan Suiter: So these are the largest of the ones that we deal with. 499 00:36:28,900 --> 00:36:30,200 Dan Suiter: Their biology is a little bit different 500 00:36:30,320 --> 00:36:31,140 Dan Suiter: than where you find them. 501 00:36:31,200 --> 00:36:32,560 Dan Suiter: Their ecology is a little bit different 502 00:36:32,660 --> 00:36:34,900 Dan Suiter: than where you might find smoky brown roaches. 503 00:36:35,440 --> 00:36:37,280 Dan Suiter: I have found smoky browns and Americans living 504 00:36:37,320 --> 00:36:38,940 Dan Suiter: in the same tree hole together happily, 505 00:36:40,440 --> 00:36:43,780 Dan Suiter: but where you'll principally find Americans, 506 00:36:43,820 --> 00:36:45,079 Dan Suiter: you won't find smokies. 507 00:36:45,200 --> 00:37:03,320 Dan Suiter: So, Americans will live with smokies in tree holes in in other locations, but you're typically not going to find smoky brown roaches living in the classic habitats that like a like a sewer, where you might find American roaches. 508 00:37:03,780 --> 00:37:04,660 Dan Suiter: So here is a sewer. 509 00:37:05,200 --> 00:37:08,400 Dan Suiter: It's a sewer situation at nighttime. 510 00:37:10,240 --> 00:37:12,140 Dan Suiter: There's a smoky brown roach right there. 511 00:37:12,480 --> 00:37:13,580 Dan Suiter: There's another one right there. 512 00:37:14,050 --> 00:37:15,020 Dan Suiter: They just, I don't know, 513 00:37:15,080 --> 00:37:17,540 Dan Suiter: they want to be friends with the American roaches here. 514 00:37:17,660 --> 00:37:20,040 Dan Suiter: But most of all the rest of these are American roaches 515 00:37:20,700 --> 00:37:23,260 Dan Suiter: and they're coming up out of these manhole covers 516 00:37:23,320 --> 00:37:23,820 Dan Suiter: at night time. 517 00:37:25,820 --> 00:37:30,980 Dan Suiter: And I tell the story of years ago at Purdue, 518 00:37:31,240 --> 00:37:33,680 Dan Suiter: we were doing, we would do cockroach research with 519 00:37:38,320 --> 00:37:53,580 Dan Suiter: American roaches and you'd have a manhole cover like this in the pavement and a car would come by and run over a bunch of these roaches and kill them and squash them and all their mates would run back into the sewer and a few minutes later there you see these antennae come out and they would come out and they would start eating 520 00:37:54,760 --> 00:37:56,740 Dan Suiter: The ones that are just, they're so starved, 521 00:37:56,820 --> 00:37:58,700 Dan Suiter: there's so much, that's why they're so baitable. 522 00:37:59,200 --> 00:38:01,560 Dan Suiter: They come out and they start looking for something to eat. 523 00:38:02,260 --> 00:38:05,100 Dan Suiter: And the first thing they find is a squashed mate. 524 00:38:06,040 --> 00:38:07,640 Dan Suiter: And they go straight for the uric acid. 525 00:38:07,780 --> 00:38:08,460 Dan Suiter: That's all they eat. 526 00:38:08,740 --> 00:38:10,120 Dan Suiter: They go straight for the uric acid. 527 00:38:12,820 --> 00:38:18,300 Dan Suiter: So, some of you have been in the industry a long time, remember, I think it was a Dursban product called Killmaster. 528 00:38:18,330 --> 00:38:24,520 Dan Suiter: Do you remember that? It was a paint. You would take this manhole cover off and paint it around the inside edge. 529 00:38:24,520 --> 00:38:29,440 Dan Suiter: It was white. It was almost like a paste and you would paint it on. It was chlorpyrifos. 530 00:38:30,620 --> 00:38:31,840 Dan Suiter: It was a good product. 531 00:38:33,780 --> 00:38:36,920 Dan Suiter: And that and there were, we don't have any of these baits anymore. 532 00:38:37,040 --> 00:38:41,080 Dan Suiter: Most of the baits are in gel, most of the good gel baits we have come in like a syringe now, 533 00:38:41,200 --> 00:38:44,020 Dan Suiter: but there used to be tubs of bait. 534 00:38:44,080 --> 00:38:45,000 Dan Suiter: We need a really good... 535 00:38:46,380 --> 00:38:52,760 Dan Suiter: wide, cheap bait, wide scale bait, you get two, three pounds of it at a time in a paste. 536 00:38:53,230 --> 00:38:58,940 Dan Suiter: There was something called, it works in blue diamond, two different boric acid baits, [VERIFY: "it works in blue diamond", two boric acid bait product names] 537 00:38:59,070 --> 00:39:04,580 Dan Suiter: and it was blue, and you would put it on with a knife, and the cockroaches just loved, these 538 00:39:05,040 --> 00:39:10,400 Dan Suiter: large roaches loved it. The problem with using inexpensive bait is these roaches can eat a lot 539 00:39:10,400 --> 00:39:12,820 Dan Suiter: of bait. I mean, tubes of it. 540 00:39:13,100 --> 00:39:18,820 Dan Suiter: You've got large populations in an elevator shaft or something like that. 541 00:39:20,680 --> 00:39:21,460 Dan Suiter: They can eat a lot of bait. 542 00:39:21,620 --> 00:39:22,700 Dan Suiter: They can eat a lot of gel bait. 543 00:39:25,040 --> 00:39:28,220 Dan Suiter: Now we've got some American roaches here. 544 00:39:28,320 --> 00:39:33,540 Dan Suiter: This is a pretty cool video where we had a bunch of American roaches put in this tub 545 00:39:33,660 --> 00:39:34,140 Dan Suiter: right here. 546 00:39:34,960 --> 00:39:38,920 Dan Suiter: I think at some point, coming up, they're going to give me a little bit of a surprise. 547 00:39:40,620 --> 00:39:42,840 Dan Suiter: see the first and second and third instar. 548 00:39:43,100 --> 00:39:47,400 Dan Suiter: Americans there and then this one comes up here on the camera. 549 00:39:49,240 --> 00:39:57,020 Dan Suiter: And then we had other videos of more of these big old stinky 550 00:39:58,000 --> 00:40:02,700 Dan Suiter: American cockroaches that were doing kind of doing their thing. 551 00:40:03,440 --> 00:40:05,520 Dan Suiter: We'll try to get some new videos for next time. 552 00:40:08,000 --> 00:40:21,480 Dan Suiter: So that's American and smoky brown we have, you know, we have oriental cockroaches we, we have not seen oriental cockroaches in this area in Georgia here in Griffin in quite some time there was a local park here. 553 00:40:24,300 --> 00:40:26,720 Dan Suiter: where they had shown up. 554 00:40:28,940 --> 00:40:31,020 Dan Suiter: I'm gonna show you another cockroach here in just a second 555 00:40:31,040 --> 00:40:32,360 Dan Suiter: called the Turkestan cockroach 556 00:40:32,420 --> 00:40:34,400 Dan Suiter: that showed up right here in Griffin. 557 00:40:35,640 --> 00:40:41,380 Dan Suiter: It was mainly known from the Southwestern United States. 558 00:40:41,840 --> 00:40:44,300 Dan Suiter: It out-competes the Oriental cockroach. 559 00:40:44,400 --> 00:40:49,579 Dan Suiter: So it has completely outcompeted the Oriental cockroach out in the southwest. 560 00:40:49,839 --> 00:40:56,700 Dan Suiter: But this is what the males of an Oriental cockroach have wings that only cover about two-thirds of the abdomen. 561 00:40:57,420 --> 00:41:01,339 Dan Suiter: The female is wingless. This looks a lot like that big cockroach from Florida. 562 00:41:01,339 --> 00:41:05,359 Dan Suiter: I was telling you about the Florida woods roach, that real big honking thing. 563 00:41:06,440 --> 00:41:08,520 Dan Suiter: Again, these are not from the U.S. 564 00:41:08,700 --> 00:41:14,720 Dan Suiter: These oriental roaches eating some bait that we put out at the park here in Griffin. 565 00:41:16,060 --> 00:41:22,500 Dan Suiter: Talked about this already, so baiting these roaches is, or a handful of bait up in tree holes, 566 00:41:22,579 --> 00:41:27,680 Dan Suiter: things like that are a really good way to go. Here's an ootheca that has been parasitized 567 00:41:28,020 --> 00:41:33,460 Dan Suiter: by a parasite. And this is a, that hole that you see right there is a hole that a 568 00:41:34,060 --> 00:41:36,220 Dan Suiter: that a small little wasp that thing that's only a 569 00:41:36,700 --> 00:41:46,300 Dan Suiter: So, as when that actually chewed a hole to get out and then 60 or 80 of its buddies actually emerged from that in case that's how small these things are. 570 00:41:48,880 --> 00:41:52,720 Dan Suiter: Cockroach researchers have forever. 571 00:41:53,600 --> 00:42:02,800 Dan Suiter: As long as I can remember, you have to have a need, you have to have a way of evaluating 572 00:42:03,940 --> 00:42:06,860 Dan Suiter: your cockroach population non-destructively. 573 00:42:08,560 --> 00:42:13,900 Dan Suiter: So if you want to trap cockroaches for some reason, the reason I bring this up here is 574 00:42:14,160 --> 00:42:18,880 Dan Suiter: in some situations you may have a case where somebody doesn't want to use pesticides. 575 00:42:20,300 --> 00:42:25,420 Dan Suiter: seeing more of that. Whether it's a spray or a bait, somebody, maybe they don't, they got dogs, 576 00:42:25,599 --> 00:42:30,960 Dan Suiter: you know, hunting dogs or whatever, they don't want to use any type of bait. This is a really good 577 00:42:32,280 --> 00:42:35,000 Dan Suiter: system to trap a lot of cockroaches very quickly. 578 00:42:35,300 --> 00:42:38,820 Dan Suiter: So we take a quart can, which I had it. 579 00:42:39,280 --> 00:42:40,020 Dan Suiter: I don't have a cup. 580 00:42:40,020 --> 00:42:42,880 Dan Suiter: I don't have one here, but this is just a quart paint can. 581 00:42:42,880 --> 00:42:43,540 Dan Suiter: I got at Home Depot. 582 00:42:44,380 --> 00:42:47,100 Dan Suiter: You take a little bit of mineral oil and Vaseline, 583 00:42:47,400 --> 00:42:50,360 Dan Suiter: mix them one-to-one to get this slickness 584 00:42:50,980 --> 00:42:52,380 Dan Suiter: and you coat the inside. 585 00:42:53,560 --> 00:42:57,900 Dan Suiter: inside lip of this paint can with that mineral oil Vaseline. 586 00:42:58,780 --> 00:43:02,860 Dan Suiter: And then you take a cup, some type of small cup, 587 00:43:03,620 --> 00:43:06,880 Dan Suiter: and a piece of screen, and you take white bread, 588 00:43:07,460 --> 00:43:11,780 Dan Suiter: and you pour cheap beer into, don't waste good beer, 589 00:43:12,500 --> 00:43:14,840 Dan Suiter: pour cheap beer onto this white bread, 590 00:43:14,840 --> 00:43:17,780 Dan Suiter: and you take that white bread, that soaked white bread, 591 00:43:17,840 --> 00:43:20,560 Dan Suiter: and you put it in this cup, you put a screen over the top of it. 592 00:43:21,460 --> 00:43:29,599 Dan Suiter: It's really pungent. And you take that, you put that in the bottom of the can, and you put that against a wall somewhere where you've seen these large roaches. 593 00:43:29,859 --> 00:43:31,400 Dan Suiter: And at night time, you'll come back the next morning. 594 00:43:33,260 --> 00:43:34,700 Dan Suiter: And we did it last summer. 595 00:43:35,829 --> 00:43:45,740 Dan Suiter: We got, typically, this was common, the trap catch you see here, but there were times where we would catch 75 adult cockroaches in a paint can overnight. 596 00:43:46,300 --> 00:43:50,940 Dan Suiter: And then you just put some hot soapy water in there and be done with it and then you can redo the can. 597 00:43:52,140 --> 00:43:55,520 Dan Suiter: That's a really good way to trap cockroaches. We do it for German roaches too. 598 00:43:56,680 --> 00:44:10,520 Dan Suiter: What they'll do is use it rather than paint cans, they'll use baby food jars and just put a little bit of Vaseline on the inside of the baby food jar, put some attractant, maybe a piece of dog food or a banana works really well because it's so pungent. 599 00:44:10,520 --> 00:44:15,680 Dan Suiter: always put these traps against the wall because roaches that are... 600 00:44:14,900 --> 00:44:16,980 Dan Suiter: Don't put them out in the middle of the floor somewhere. 601 00:44:17,119 --> 00:44:20,640 Dan Suiter: Always put them against the wall and then the smell wafts up and 602 00:44:20,660 --> 00:44:23,500 Dan Suiter: the cockroaches come down and fall in the trap and can't get out. 603 00:44:26,579 --> 00:44:31,480 Dan Suiter: We did some work in this park here locally with some cockroach. 604 00:44:32,400 --> 00:44:39,859 Dan Suiter: some cockroach gel. This is when Advion was first coming out. The real good Advion gel for German 605 00:44:40,079 --> 00:44:46,020 Dan Suiter: roaches is years ago, 10 years ago now, but before it actually got its label we wanted to just play 606 00:44:46,119 --> 00:44:51,839 Dan Suiter: with it in a local park. And so of course there were smoky brown roaches and American roaches 607 00:44:51,940 --> 00:44:55,700 Dan Suiter: and brown roaches behind this wall right here. You put out a little bit of gel. 608 00:44:56,400 --> 00:45:00,680 Dan Suiter: and boom, come out at nighttime and they immediately begin to consume the bait. 609 00:45:01,980 --> 00:45:05,839 Dan Suiter: And then, then they all started to die. The next day you come out here and die. 610 00:45:06,319 --> 00:45:11,420 Dan Suiter: I had a grad student that just, she just finished, went to work for Valent, but she had a project where 611 00:45:12,160 --> 00:45:18,579 Dan Suiter: she was collecting these roaches and there's a secondary kill of fire ants. So, 612 00:45:19,300 --> 00:45:33,760 Dan Suiter: Some of you may have noticed this, when you kill a lot of these large roaches like this outside, or you kill anything, kill large populations of insects on the outside, in the south, one of the first things that comes after them is fire ants. 613 00:45:34,380 --> 00:45:35,180 Dan Suiter: And, and 614 00:45:37,180 --> 00:45:42,240 Dan Suiter: And when we do our, we kill, do our cockroach kill like this, 615 00:45:44,200 --> 00:45:48,340 Dan Suiter: inevitably it's always fire ants that come after these dead roaches. And we were taking these, 616 00:45:48,420 --> 00:45:52,040 Dan Suiter: she was taking these dead roaches and doing it in a lab and in the field like this, 617 00:45:52,780 --> 00:45:56,360 Dan Suiter: and feeding them to fire ant colonies and killing the entire fire ant colony because 618 00:45:56,440 --> 00:46:00,700 Dan Suiter: it was bait left over. There was, you have a cockroach that was killed by indoxacarb. 619 00:46:01,200 --> 00:46:05,520 Dan Suiter: There's an indoxacarb, activated indoxacarb, still in the cockroach. 620 00:46:05,599 --> 00:46:07,859 Dan Suiter: The cockroach is now a fire ant bait. 621 00:46:08,810 --> 00:46:11,420 Dan Suiter: And so you're actually not just killing the cockroaches, 622 00:46:11,430 --> 00:46:14,000 Dan Suiter: you're actually killing, having an impact on the fire ants as well. 623 00:46:15,140 --> 00:46:16,200 Dan Suiter: It was a pretty cool little study. 624 00:46:17,740 --> 00:46:19,500 Dan Suiter: So again, this is the gel. 625 00:46:20,180 --> 00:46:21,940 Dan Suiter: And by the way, it's not just Advion, 626 00:46:22,500 --> 00:46:25,420 Dan Suiter: any gel you put out here, they will react this way to it 627 00:46:25,420 --> 00:46:26,560 Dan Suiter: because they're half starved. 628 00:46:28,240 --> 00:46:29,780 Dan Suiter: And they come out, you know. 629 00:46:31,240 --> 00:46:32,840 Dan Suiter: That was a really cool video of a. 630 00:46:34,640 --> 00:46:40,180 Dan Suiter: An American cockroach eating, I can't remember what kind of, what gel that was, but when 631 00:46:40,280 --> 00:46:44,640 Dan Suiter: they start chewing on the bait, they can eat a lot of bait. 632 00:46:45,400 --> 00:46:50,220 Dan Suiter: This cockroach, I can't remember, it ate half of this, it's amazing the amount of bait that 633 00:46:50,300 --> 00:46:50,420 Dan Suiter: they ate. 634 00:46:51,000 --> 00:46:54,760 Dan Suiter: This cockroach right here ate probably half of that pile of bait right there. 635 00:46:55,000 --> 00:46:58,560 Dan Suiter: And we've had, we in our trials, we'll go in, 636 00:46:58,620 --> 00:47:00,220 Dan Suiter: we'll have 25 of those large roaches, 637 00:47:00,540 --> 00:47:03,420 Dan Suiter: and we'll put out the amount that would fit on a quarter. 638 00:47:03,980 --> 00:47:05,900 Dan Suiter: It'll come back the next day, it's all gone. 639 00:47:06,660 --> 00:47:08,680 Dan Suiter: So they really can eat you out of house and home. 640 00:47:10,680 --> 00:47:11,560 Dan Suiter: In just a few minutes, 641 00:47:11,560 --> 00:47:13,040 Dan Suiter: let me talk a little bit about German roaches. 642 00:47:14,860 --> 00:47:17,600 Dan Suiter: So I wanted to make this point right here. 643 00:47:17,780 --> 00:47:18,200 Dan Suiter: So, 644 00:47:18,520 --> 00:47:20,120 Dan Suiter: Um... 645 00:47:20,740 --> 00:47:24,880 Dan Suiter: So German roaches, of course, hide in cracks and crevices because of that. 646 00:47:24,980 --> 00:47:28,660 Dan Suiter: They are cockroaches, of course, and they're most active at nighttime. 647 00:47:28,960 --> 00:47:33,840 Dan Suiter: So I guess the point I'm trying to I wanted to make here is we go into a kitchen area like this. 648 00:47:34,880 --> 00:47:35,960 Dan Suiter: There's lots of dark spaces. 649 00:47:37,180 --> 00:47:38,180 Dan Suiter: There's lots of water. 650 00:47:38,540 --> 00:47:41,100 Dan Suiter: You've never been in a kitchen there where there was not enough water 651 00:47:41,180 --> 00:47:45,800 Dan Suiter: to keep cockroaches alive or food, for that matter. Right. So. 652 00:47:50,440 --> 00:47:58,619 Dan Suiter: Going back to this situation right here, you probably can't keep enough water out of a 653 00:47:58,820 --> 00:48:03,619 Dan Suiter: kitchen to actually desiccate cockroaches out. 654 00:48:03,619 --> 00:48:04,099 Dan Suiter: You can't. 655 00:48:06,180 --> 00:48:08,280 Dan Suiter: We've already talked about this right here, but. 656 00:48:10,080 --> 00:48:17,800 Dan Suiter: Ask yourself this point right here, the last kitchen you were in, whether you were eating there or you were in the middle of the night doing a treatment. 657 00:48:19,370 --> 00:48:25,540 Dan Suiter: You go into, and this was actually a pretty clean kitchen, but it's an older kitchen. 658 00:48:26,360 --> 00:48:31,280 Dan Suiter: Ask yourself, is food or water limited anywhere in that environment right there? Of course it's not. 659 00:48:31,700 --> 00:48:36,720 Dan Suiter: And this is right outside that prep area that I just showed you. 660 00:48:36,900 --> 00:48:38,440 Dan Suiter: This is where the lady is serving food. 661 00:48:40,440 --> 00:48:42,420 Dan Suiter: Is food or water limited anywhere right here? No. 662 00:48:43,060 --> 00:48:44,359 Dan Suiter: She's got the food right there. 663 00:48:45,480 --> 00:48:47,260 Dan Suiter: She's always spilling food on the floor. 664 00:48:47,380 --> 00:48:50,460 Dan Suiter: She's kicking it under these coolers over here. 665 00:48:50,560 --> 00:48:52,359 Dan Suiter: It's three feet back to the wall. 666 00:48:52,700 --> 00:48:54,000 Dan Suiter: These coolers are never moved. 667 00:48:54,500 --> 00:49:11,220 Dan Suiter: Of course, there's food underneath there and then of course, you know, the people that are eating in the in the dining area are always dropping food so that I the point I'm trying to make here in these environments, food and water not limited, it doesn't take a roach whole lot of food to survive. 668 00:49:11,780 --> 00:49:12,360 Dan Suiter: And of course. 669 00:49:13,820 --> 00:49:20,880 Dan Suiter: They go a long time without food, but they can't go very long without water, but water is not limited in a kitchen. 670 00:49:22,480 --> 00:49:29,420 Dan Suiter: So, German roaches have this really peculiar 671 00:49:29,900 --> 00:49:35,240 Dan Suiter: biology. It's really interesting. And many insects do this. So, 672 00:49:36,640 --> 00:49:39,160 Dan Suiter: in their talk a little bit about their reproductive biology, keep 673 00:49:39,240 --> 00:49:42,400 Dan Suiter: this in mind. This is important. A male cockroach can 674 00:49:42,539 --> 00:49:45,760 Dan Suiter: inseminate multiple females. Right? So you've got a 675 00:49:45,779 --> 00:49:48,020 Dan Suiter: population of males in any kitchen, you got a population 676 00:49:48,180 --> 00:49:49,500 Dan Suiter: males, a population of females. 677 00:49:49,900 --> 00:49:57,660 Dan Suiter: So they go through six or seven instars, they turn into an adult, the female releases a pheromone, attracts a male, and they mate. 678 00:49:58,440 --> 00:50:05,700 Dan Suiter: She has to do that one time to produce all the egg cases that she'll ever make, and she makes about six or seven of them. 679 00:50:06,300 --> 00:50:14,980 Dan Suiter: This is important. Moths do this and they're going to mate. Many insects have to just mate one time, produce all the eggs they'll ever mate, they'll ever need. 680 00:50:15,640 --> 00:50:24,960 Dan Suiter: So, once a female becomes that adult, she goes through six or seven, what we call reproductive cycle, and then she dies of old age. 681 00:50:25,620 --> 00:50:27,520 Dan Suiter: Well, reproductive cycle is just this. 682 00:50:35,840 --> 00:50:36,280 Dan Suiter: She... 683 00:50:30,460 --> 00:50:37,040 Dan Suiter: you've seen a German cockroach female with a ootheca protruding out of her rear end. 684 00:50:37,780 --> 00:50:43,660 Dan Suiter: We call that gravid. When she's gravid, when she's that way, she's pregnant. Well, 685 00:50:44,640 --> 00:50:48,900 Dan Suiter: she's pregnant for about a month like that. We call that a gravid female over here. 686 00:50:49,380 --> 00:50:54,040 Dan Suiter: And then she hatches at a case, there's 35 to 45 first instar babies that come out. 687 00:50:54,900 --> 00:50:57,980 Dan Suiter: And then that's about a third of her body weight. 688 00:50:58,500 --> 00:51:01,700 Dan Suiter: And then it's not. 689 00:51:02,740 --> 00:51:06,500 Dan Suiter: Then the baby's run away, and then she's free now. 690 00:51:07,180 --> 00:51:11,880 Dan Suiter: She's been released, and she's starting the next reproductive cycle. 691 00:51:12,410 --> 00:51:14,540 Dan Suiter: And it's during that 10-day period right there. 692 00:51:16,180 --> 00:51:20,040 Dan Suiter: that there's worked a really cool study done at Purdue years ago, 693 00:51:22,060 --> 00:51:24,180 Dan Suiter: that showed that during that 10-day period, 694 00:51:25,420 --> 00:51:29,320 Dan Suiter: that's when she eats most of her food and drinks most of her water, 695 00:51:29,740 --> 00:51:31,280 Dan Suiter: and does most of her movement. 696 00:51:31,920 --> 00:51:34,360 Dan Suiter: Because if she's eating that much food and drinking that much water, 697 00:51:34,440 --> 00:51:35,840 Dan Suiter: she's got to move a lot more. 698 00:51:36,500 --> 00:51:39,240 Dan Suiter: During that 27-day period over here when she is, 699 00:51:40,900 --> 00:51:49,299 Dan Suiter: When she's gravid, she goes back in a hollow leg of a stool somewhere and literally just sits there. 700 00:51:50,079 --> 00:51:52,200 Dan Suiter: She just sits there and waits it out. 701 00:51:52,880 --> 00:51:56,440 Dan Suiter: She waits for a month because it's all about the baby cockroaches. 702 00:51:56,600 --> 00:52:01,100 Dan Suiter: She doesn't eat anything, she doesn't drink anything, and she doesn't move. 703 00:52:01,540 --> 00:52:05,880 Dan Suiter: She goes back in her little harborage and she sits back there and doesn't do anything. 704 00:52:06,160 --> 00:52:12,820 Dan Suiter: So I guess one of the points I'm trying to make here is if you're not getting your aerosols in screw holes 705 00:52:14,160 --> 00:52:20,380 Dan Suiter: and popping tops and getting aerosols down in there or baiting, getting baits into cracks in crevices, 706 00:52:21,120 --> 00:52:23,100 Dan Suiter: you're not reaching this female population. 707 00:52:23,800 --> 00:52:24,320 Dan Suiter: and 708 00:52:25,559 --> 00:52:30,799 Dan Suiter: Biologically, if you're going to limit a population of animals, 709 00:52:31,599 --> 00:52:32,900 Dan Suiter: you can kill all the males you want, 710 00:52:35,539 --> 00:52:42,539 Dan Suiter: but that's not going to impact a population of insects where the female only has to mate one time. 711 00:52:43,000 --> 00:52:49,000 Dan Suiter: So in order to actually impact the population of insects, you have to go after the female population. 712 00:52:49,960 --> 00:52:53,420 Dan Suiter: And I use a hunting analogy, I hunt. 713 00:52:54,140 --> 00:52:59,980 Dan Suiter: And, you know, in Georgia, DNR thinks we're overpopulated with deer. 714 00:53:01,000 --> 00:53:03,000 Dan Suiter: So you can take 12 does a year. 715 00:53:03,570 --> 00:53:08,920 Dan Suiter: You only kill two bucks, but you can take 12 does because you want to reduce the population of an animal. 716 00:53:08,920 --> 00:53:10,940 Dan Suiter: You have to reduce the female population. 717 00:53:11,100 --> 00:53:15,320 Dan Suiter: So this is what she does. She does this six or seven times and she dies. 718 00:53:15,800 --> 00:53:20,460 Dan Suiter: So if you do the math, she's basically pregnant for about 75% of her adult life. 719 00:53:21,480 --> 00:53:23,880 Dan Suiter: And she's much less killable during that time. 720 00:53:26,000 --> 00:53:30,680 Dan Suiter: So I'm not going to show you the gory numbers here, but the females are less active. 721 00:53:30,900 --> 00:53:36,460 Dan Suiter: They spend more time in the harborage. It's like 90% of their time they spent harboring. 722 00:53:37,039 --> 00:53:43,180 Dan Suiter: They visit resource sites less often, meaning food and water, and they consume, when they get there, they consume fewer resources. 723 00:53:44,059 --> 00:53:49,400 Dan Suiter: So, the key here, of course, is, as always, this has always been true, we've been doing this. 724 00:53:51,020 --> 00:53:54,260 Dan Suiter: You've been doing this a year, you've been doing this 40 years, you know that you've 725 00:53:54,280 --> 00:53:57,579 Dan Suiter: got to inspect thoroughly and you've got to treat cracks and crevices. 726 00:53:59,020 --> 00:54:04,260 Dan Suiter: That terminology, crack and crevice pest control, was coined by a company called Whitmire years 727 00:54:04,320 --> 00:54:04,940 Dan Suiter: and years ago. 728 00:54:05,300 --> 00:54:07,680 Dan Suiter: Dan Stout, a guy named Dan Stout coined that term. 729 00:54:07,680 --> 00:54:10,400 Dan Suiter: I think it was Dan Stout coined that term years and years ago. 730 00:54:10,920 --> 00:54:12,359 Dan Suiter: And the whole Whitmire... 731 00:54:13,619 --> 00:54:20,299 Dan Suiter: Micro-Gen, it was Whitmire, the back end of Whitmire Micro-Gen, their whole series of products 732 00:54:20,400 --> 00:54:25,260 Dan Suiter: was based on crack and crevice pest control. Everything from their aerosols to their, when 733 00:54:25,359 --> 00:54:30,359 Dan Suiter: baits finally came along, everything was based on putting it back in a crack and crevice where 734 00:54:30,420 --> 00:54:33,220 Dan Suiter: the cockroaches live. Anyway, I think I'm... 735 00:54:34,859 --> 00:54:36,240 Dan Suiter: It's about four o'clock. 736 00:54:36,359 --> 00:54:39,619 Dan Suiter: So yeah, this is, this holds true. 737 00:54:39,920 --> 00:54:41,260 Dan Suiter: You know, if you're not getting on your back 738 00:54:41,320 --> 00:54:44,339 Dan Suiter: and looking behind things with a flashlight, 739 00:54:44,500 --> 00:54:47,680 Dan Suiter: you're not doing it right. 740 00:54:48,460 --> 00:54:50,800 Dan Suiter: Okay, Richie, I think I'm gonna stop 741 00:54:50,800 --> 00:54:51,140 Dan Suiter: there.
