Here is how I control mites the one time I got them from two new animals, and it worked great. Get a sterilite bin and fill it with warm (80 F) water so that it will just barely touch the top of your snake. Now add just enough Listerine to slightly color the water. The listerine will steralize any mites that do not drown, and works as an antisceptic for the bites. Put your snake in and let it soak. While the animal is soaking, completely sterilize and clean the cage and all furniture. Once the cage is clean, I would place paper towels down so it will be easier for you to see any mites. Gently pat the snake dry. Now for the fun part! Get some mineral oil and put a good amount on your hands. Let the snake crawl through your hands until it's body is coated. Use a Qtip to get it around the eyes really good. The mineral oil will smother any remaining mites. Repeat in a week. This worked great for me. I saw no mites after the first treatment, but repeated the second treatment just because. Never had mites again.

If you have a canister vaccum cleaner, place a fela collar in the canister before you vaccum. This will kill any mites you vaccum up when you are cleaning. Good luck.

The treatment sounds out there, but I got it out of a vet book, and my vet also recommended it. I was treating hognose, which there are reports of them being very sensitive to Provent-a-mite. This is a poison free alternative.
