When I treat for mites I use a combination treatment that works really well. I treat the snakes for mites by coating them in oil for about 15-20 minutes, while that sits I spray their enclosures and let them dry. Before putting the snake back it gets washed with a little dish soap. This usually kills all the live mites and the tub treatment kills any that hatch after treating. This has been very effective for me in the past.
