I just went through mites with my pied who has been in quarantine; I used the Reptile Spray from Petco and it worked great. Thoroughly cleaned his tank and his hides while I let him soak to drown the little pests.

Placed paper towels in his tank along with his clean hides; then I sprayed him with the Reptile Spray. I also put a little mineral oil around his heat pits, eyes and under his chin in the fold of skin (found a few hiding in there before I soaked him). I repeated this treatment 3 times and I haven't seen any more mites in a few weeks so I'm hoping I killed all of them.
