hey there!
i just mentioned that i would post my mite advice, so here is the perfect opportunity to do it:
it's a good thing you are moving out of the dorm so then you can start fresh. i would throw the bedding out for sure. i know it is a $ concern but it is less of a hassle and worth it in the long run.
scrub the cage good and spray the inside with Provent a Mite. let it sit a while before rinsing and drying. use only paper towels when treating for mites that way you can see if they are really gone or not. sprinkle a small amount of Sevin-5 dust on the bottom of the cage before laying down a layer of paper towels. keep the set-up VERY basic with just a water dish and some extra paper towels for your snake to hide under. in the meantime, you can soak/sterilize the regular cage furnishings and then spray them with Provent a Mite as a pre-caution. store them in a mite-free box until your snake is pest free.
your snake should be soaked in plain, warm water for 20 minutes and then placed under a running faucet to flush out any lodged mites, or mites that are hanging out by his eyes. take a q-tip and dab a bit of petro. jelly around the eyes, vent and any folds of skin to kill mites living in these hard to reach places. then, spray your hands with a mite-killing solution and rub all over the snakes body, taking care around the nose and mouth. i have used Frontline spray in small amounts without any ill effects and it is very effective in breaking the mite life cycle. i may get some heat for that, so use your best judgement. my herp vet is a well-known, trusted vet, and he recommends it as a one-time method of killing those lil' buggers. and btw, pyrethin is NOT an ingredient found in Frontline. wait at least a day before putting the snake's water dish back in the cage. once your snake is in his sterile cage, change those paper towels frequently and spray around the cage with some more Provent a Mite. make sure there is good ventilation.
i was able to eradicate a bout of mites in this manner. again, use common sense and good judgement - wash your hands and make sure your snake is far away from any other herps. i know this can be difficult in college, so that means across the room with a ring of Provent-a-Mite around the cage.
hope this helps!
good luck!
