I have always used reptile relief for both the little red mites, and for ticks. I rub it over them from head to toe, and put it on around the face with a q-tip. Once every 5-7 days for at least 3 treatments.
Regardless of how you treat it, keep it away from your other herps until you do, and wash your hands very good inbetween, and dont let the lizards touch your clothes and other stuff that the other herps might touch.- just to be safe. Remember, you cant always see baby mites/ticks.
Almost every aligator lizard I find has mites and ticks.
I havent seen the red mites on snakes either-yet, knock on wood, but I'd still be careful.
