This YouTube video appears to have been taken by a PCO during a second visit to a badly infested apartment.
The person who posted it, iamyournot, said in the comments,
The Video doesn’t show how bad it really was, I had to stop taping because there were thousands of bed bugs running over the top of the bed, after the opening shot, the video was taken on the second visit, the room was clear by then, it took three visits to totally clean out this apartment of bed bugs.
It sounds like it was a thousand times worse in the first visit. It’s hard to believe someone could have an infestation this bad. If they did not react to bed bug bites, they must surely have seen the bed bug feces everywhere– let alone “thousands of bed bugs” running around– and wondered what was up?
I also found this lovely ad for PCI (Pest Control India):
And this one, from Suburban Exterminating:
And finally, though Harris Pest Control in Detroit makes no mention of bed bugs in their ad, this was priceless and delightful:
