Sold in Pharmacy stores as a hair lice treatment for children and adults who can't keep clean. Mix one ounce per qt. of water, but you can use less if you're only spraying a few cages. Just take out water dish and give the whole cage a light misting. Used 2x in the past 5 years. Mites were gone within a few minutes. Just quarantine new animals for a few days so mites can be caught early. I've used on snakes only, but others on this site have used on lizards with no ill effects. Two ounce bottle runs $10-12.
