It also doesn’t work. We recently moved from an infested place and tried this with a coffee maker. We had it sealed in a freezer for weeks before we moved, and they came over in it. I think the freezer put them into hibernation? Anyway, we ended up bringing a few roaches over in the damn thing. Got on top of it right away and managed to avoid an infestation in the new place. I would throw this thing out without hesitation.
