I don't want to suggest the above is the only way to treat mites it was only a suggested place to start. I have no personal experience with any mite treatment since I have never experienced mites. I am only suggesting using a tried an true mite treatment that will not harm your animal.
Here are other options.
Nix treatment.

I keep cans on Provent-a-Mite and Reptile Relief, just in case. The instructions are on the can or bottle. I personally don't believe in the once a month insecticide sprayings, suggested by Provent-a-Mite.

Provent-a-Mite has undergone more than eight years of research and clinical testing to insure that it will effectively eradicate mites and ticks that feed on snakes and will not harm the host being treated when used as directed. Provent-a-Mite can also be used to stop future infestations. Just spray on substrate, racks, enclosure openings, etc. once a month as directed to kill any disease carrying mites or ticks before they can become a problem.
Reptile Relief is not a poison. See results immediately with fast acting Reptile Relief. Dioctyl sodium sulfosuccinate and undecylenic acid kill mites and ticks on contact – without poisons – by compromising their natural chemistry. Cleans and deodorizes wounds and irritations to promote healing. Biodegradable and pH balanced, you can safely spray it directly on your pet at three-day intervals. For use on turtles, lizards, and snakes.
