I actually have not but if you wanted a non toxic (labour intensive) mite treatment is warm water and a few drops of soap. everyday soaks for at least 20 min twice a day and each time a absolutely spotless clean of the enclosure and the surrounding area (3 meters out) during each soak. It must be spotless and every nook and cranny, you are trying to kill as many eggs and adults trying to lay them as possible. You need to keep it up for 2-3 weeks. No chemicals and no toxins just lots of work. P-A-M works but be sure to read the MSDS sheets as it is more toxic than you might be led to believe. (carcinogen in humans)
