Are you sure they're mites, or could they be lice? Lice are a lot easier to treat and won't try to get onto any other fuzzy living things in your house (well they might try, but they won't survive like mites will). Your best bet is seeing if you have any vets in the area with exotic mammal experience. My rats got lice once and the vet just told me to go pick up some all-natural lice spray from a store. He had something he could have prescribed for them but since I had a bunch of babies he was afraid the prescription stuff would hurt/kill them.
