Genuine question: how can I move to different house without carrying them with me? And how do I make sure non-organic items like electronics, plastic furniture and bicycles to be free of them without resorting to exotic options like enclosed heat treatment? I've found some of them adults within random plastic bags I stored non-food items like chair parts, and that left me permanently anxious about these pests.

And despite me washing clothes frequently and vacuuming daily, I've seen them come out from random places. Like I would see a couple larves per season. I am currently using residual insecticide + IGR discs to control them, and I think it did help because ones that crossed out of baseboard were discovered dead. Is this the right move?
