Nix is by far the safest mite treatment available. It's a shampoo for people with head lice, crabs, or any other body bugs..lol
You can buy it any pharmacy. You just dilute one bottle of Nix with one gallon of water and spray all over snake and enclosure. It is just as effective as BK and PAM, but <B>alot</b> safer.
I agree with Kahane. There is no reason that mites would be able to spread anywhere in your collection as long as proper treatment and prevention proceudres are followed.
