Perhaps one of the more annoying aspects of a bed bug infestation is that even when you don't see them anymore, you still come across little discoveries like this just so you know they're never really gone.
What you're looking at in this yellow basin are bed bug shell casings. As bed bugs grow, they also grow a new shell which breaks the old shell, kind of like a snake shedding its skin. This basin was empty and under my bed for the last month. Now M and I can't even remember the last time we saw a live bed bug or even been bitten by one, but this disgusting find serves as a friendly reminder that we should never rest easy. We should never stop inspecting our own homes, and most definitely, we should never stop cleaning. Most importantly this discovery serves as a reminder that those who have endured bed bug infestation should never, ever assume their homes are finally bed bug-free.
One of my financial goals if for M and I to have enough money one day to hire someone to do all this bed bug cleaning (the weekly mopping, the inspections, etc.) so we can somewhat relax.
