body. different body parts like his arm. and it's all eaten alive. i mean, there's no skin left showing. it's just all chapped as if somebody burned his skin with fire. he would have had hundreds and hundreds of bedbugs on his body while he was sleeping and they'd be feeding. >> the man had tried defending himself using pesticide products from his local garden store. >> as you see in the videos, it didn't change one thing. i don't think any of them were dead when we got there. they were all still very much alive. >> they're running like roaches. >> we walk in, and there were literally piles of bedbugs. probably well over a million in just one bedroom. and in the video you'll see the shells they shed. a bedbug sheds six times before it becomes an adult. and the skins were in piles. they'll pick them up with their hand. and it's just like dust. it looks like tobacco.
