prevent a mite
http://www.pro-products.com/index.ph...d=53&Itemid=59
empty all the cages, clean them, spray this in there, put in paper towels, put snakes in with just a water bowl, and if you can move the whole rack/s that theyre in to another room as to not infest the rest of his collection
also, before you put the snake back in its tub, make it crawl through a wet paper towel to remove any excess mites
when you know for a fact that theyre gone, put the rack back in the room, and make sure theyre all in their original spots with original items in the tubs
and good luck
