soak her in warm water and try to have as much of her body under water as possible. the mites will drown and then you can wipe them off of her. yu will want to also watch very closely while you do this because the mites will try to save them selves and scurry to the top of her head. then you can wipe them off with a moist cotton swab. provide a water dish at all times, and she will probably hang out in there to try and drown them herself too.
What are you using for substrate? If you use something like aspen or cypress that they can burrow in and you treat that, take away the hide and they'll more than likely burrow. When they do, the PAM on the substrate will help kill the mites. Re-treat after 10 days or so to be sure.
