I have kept reptiles for a wail now and the first time i ran into mites the issue more or less got resolved with provent-a-mite. this is the second time and my female boa still has mites and i have tried provent-a-mite and new cage, nix and new cage and just sterilizing the old cage and geting new substrate and stuff. What now? its not that severe on her but they wont go away. i had an idea i might try of filling her cage up with 1-in. of water and waiting for a week or so because im assuming mites can not reproduce in water.
