I can't suggest any of the mite killing products because I don't use them. I can tell you that with mites, it's WAR. It usually takes me a couple months to eradicate mites if I bring in an infested animal. I do daily soaks in plain, lukewarm water and clean their enclosure like I'm Super OCD. You can ask people who use it but I think I've heard of applying provent-a-mite on bags of substrate when they're bought to insure they're "clean" when you start digging into them. Good luck and Godspeed!
