After that beat down, here is what to do.
Get rid of the bedding and use newspaper. Wash the enclosure. Go to the pharmacy and buy some Nix head lice shampoo. Get a 1 L spryer and use a coulple tbsp's of the Nix. < I could only find Nix in a non concentrate>. Shake the sprayer vigorously. Spray the WHOLE inside of the tank, including the snake. This worked 100% for mites in my case. Ticks will probably die, but you may have to remove the dead ones with tweezers. Look in the cavity under the snakes lower jaw. Mites tend to gather there.
Nix works great and it cheaper than the 30.00 prevent a mite, that is WAY more of a PITA to administer.
