Take a look at this: http://www.proexotics.com/FAQ_answer..._of_mites.html

That will help you get rid of the mites thoroughly. I can almost guarantee you they are not all gone, the process of getting rid of them must be a thorough one. I recommend Black Knight spray. You cannot find it in any pet store or hardware store; it must be purchased online. The URL I gave you also is the website that you can purchase Black Knight from. It's $20 plus shipping for a 12oz can. Here is the URL to purchase it: http://proexotics.com/supplies.html scroll down, it's in there.

Good luck with those nasty critters.
