I had a mite outbreak a few weeks back. We used the commercial sprays for weeks without success. It was suggested that i try Nix. One small bottle of nix in one gallon of water, mix well, pour in spray bottle, spray snake and enclosure.
The mites were gone after that first treatment and have not returned. I did do the two follow-up treatments as suggested just to be safe. There have been no bad side effects from the Nix and none of the snakes seemed to be bothered by it.
Go for it!
