It definitely pays to watch out for bed bugs, because a rare bite or two may turn into hundreds of bites per night, after the filthy little critters begin to multiply. The National Geographic put together a video that shows how bed bugs crawl out of the walls to bite people right before dawn, when they’re in their deepest sleep period of the night.
And here’s a video that shows what a serious infestation of bed bugs looks like. It’s the stuff of horror movies, and one definitely wouldn’t want to live in such a place, ever. Yet those poor old folks are stuck there, getting bitten by the bugs every day and every night.
So, it looks like the thing to do you see the first bed bug is to go all out. Get the strongest pesticide you can get, apply it to all the crevices where the critters could be, squash all the ones you can see, and hope you’ve staved off an invasion. Get all the help you can get, don’t give them an inch.
