I get a lot of questions about bed bugs from folks who are getting eaten alive. I wrote a blog post for the Penn Medicine Health and Wellness Blog. I hope you find some helpful hints there. (Check out some of the other articles by other Penn docs while you’re there.)
TL;DR: You WILL have to deal with bed bugs, sometime, somewhere, some way. Know how to control them before you get an infestation, and you can avoid making the problem much worse (and more expensive).
