Nix is available at any pharmacy. It is probably the safest treatment you can use to treat for mites. You mix 1 bottle of Nix (4 oz) to 1 gallon of water and spray snake and enclosure. For internal parasites Panacur and Flagyl are the most commonly used treatments. You need to an Rx to get Flagyl, but Panacur can be purchased at most farm supply stores (well, unless you live in my area).
