Goodluck getting rid of mites when there are a 100 snakes, that will be a massive undertaking, cleaning, spraying, soaking. You should have listened in the first place, sounds pretty irrisponsible to me, cut your losses, sounds like youve done enough already, plus the fumes from provent-a-mite can kill snakes so make sure you follow the directions on the can if you can (doesnt sound like you follow directions very well), Dont make things worse, just admit what happened so he can take care of the issue properly, better than you thinking you got all the mites only for him to find an infested collection when he gets home.![]()
