Forget the Four Paws junk, it may alleviate some of the problem but it will never resolve it.
Follow this link, and get some of this stuff. Widely accepted around the reptile community as the best and only reliable course of treatment. Yes, there are home made remedies out there, but this stuff is worth every cent and then some. Don't mess around, just get yourself a can of Provent-a-Mite. Its good to have one around just in case at all times regardless.
