I recently purchased a snake from a "Big" breeder with mites, and as a precationary measure I'm treating all of my tubs. For those of you who use this product, how long do you wait before putting the snake back in? I have been airing these tubs with a fan for 15 minutes and they still have a bit of an odor to them but are fully dry. Also, if a snake has mites that I have not spotted, will PAM kill the mites on the snake too?
