The web wisdom says that foggers don’t kill those bugs; the poison isn’t concentrated enough. Once they’re there, they have to be starved out (3 months at room temperature) or frozen out (well below freezing) or cooked out (well over 100F) or maybe directly sprayed out (a shag rug in the house is, I suspect, giving the bugs a snug place to live as well).
Ny is infested with them...wouldnt be surprised if they were in the WH
Their favored hiding spot is behind wood trim...baseboards in particular.
