I had mites come in on a pair of black eastern hognose several years ago, and this method worked for me. Put the animal in a diluted listrine / water soak for roughly 30 minutes. Listrine basically sterilizes the mites. While the snake is soaking, completely sterilize the enclosure. When you take the snake out of the soak, gently towel dry the animal off. Now the fun part. Get some mineral oil (not cooking oil) and coat your hands. Now, give the animal a good rub down. Use a Q tip to get around the head area, especially around the eyes. (this smoothers any remaining bugs and eggs). Place animal back in the enclosure with minimun decorations (water bowl, hide, and paper towel substrate). Repeat in two weeks. Never saw a mite again after that. It is a chemical free way that works. Hoggies are sensative to PAM, so I had to go an alternative route. By the way, I got this method from a vet book.

Oh, if you put a flea collar in your vaccum bag, any mites sucked up will be killed, just be careful using it around your reptiles.
