I feel your pain. I purchased my Red Tail Boa and fortunately, someone contacted me within an hour to let me know it and another snake had mites. I've been using plastic tubs as homes for now and use fresh cheap aspen bedding (she likes to burrow) every 2-3 days as well as a bit of Natural Chemistry. I spray the plastic tubs with fairly powerful germ killers (like Lysol) and wash them repeatedly before reuse. It's been a couple of weeks now and I can no longer find mites on her when I let her run through my hands (rubbing off the NC spray and mites). However, I occasionally find a dead mite in the bedding and will continue this until I feel there are none possibly left. She will stay in quarantine and get fresh bedding for a bit after I stop with the spray to make sure none were left behind.

Hopefully it helps keep your spirits up and your mite problem goes away. This is also my first experience with them, so if I am doing something wrong, I would like to know too. I was told to keep up this process for 90 days, but it feels excessive (90 days) based on research.
