I think they wind up eating themselves after there are no more mites to feed on, if not they just die and drop off. I am sure we all smoked worse than good bugs before and didnt even know it....lol I am curious as to how they work also. Not cheap, but if they save a crop, who cares about 50 or so bux. And, it would beat the piss outa spraying 94 times a day. Best of luck with the battle.
