first and foremost, i would treat all of them to be safe. do not spray anything with such harmful chemicals right on the snake. whether it says its ok or not. i have had mites twice in my snake career. the first was with a rescue boa, that was absolutely covered in them. the second was back when i used that cypress bark crap (im 99.99999999% positive i got a bad batch of that stuff that wasnt pretreated properly and there were mites in it), and my two breeders for this coming season (hopefully) had a few on them and in their cages. i went to petsmart and got stuff callee jurassimite. its an all natural mite erradicator. i was very skeptical the first time (which was on that covered rescue boa). it is fantastic. the mites were fully gone on the boa in about 5 days. and in my retic breeders last year, they were gone the next day. and because its natural, you can use it on the snake, in the cage, on the bedding, and any decorations you may have in there, and you can use it as often as you need to, since it is non-toxic. i figure, why not try something that is non-chemical and non-toxic to them first and see.
