Can you use sevendust to kill mites off of snakes?

Yes, Sevin is relatively safe to use on snakes. However, I have found the best way to get rid of mites is to place the infected snake in a covered bucket of water for a couple hours while you thoroughly clean out the cage, wash it and replace the bedding. The mites usually drown. May have to be repeated again after a few weeks if the mites return.
