I had the same problem a few months ago...from a bad shipment of crickets I think! I ended up having to take one of my dragons to the vet. You really have to stay on top of it and remember that it may take a few treatments to completely kill the entire cycle (mites and all of the eggs). One thing you want to also remember is that mites drown when they encounter water, so my vet had me giving my little one a quick bath daily (about 5 minutes). It was just long enough for the mites to drown, but you have to make sure that you also carefully add water to his/her head because the mites will try to climb up to avoid the water. You want to make sure that while your dragon is out of the room, yougive the cage, all of its furnishings and the entire room a good cleaning. I used water/bleach with a ratio of 10:1. Remember to clean the tops of the cages because mites tend to climb high when they leave their host to lay their eggs and are often at the tops of the cages where you would least expect them. It may take a few cleanings but this will break the mite cycle. When they leave your dragon, they may inject a toxin leaving your dragon lethargic for a while which is very normal. They may also leave lesions on the skin or open sores. If this happens; bath daily allowing to drink water first and then adding betadine to the water. Add enough to the water to give the color of weak tea. After removing your dragon from the bath 10/15 minutes, use witch hazel as an astringent...if the sore is really bad you may want to add some neosporin to help in the healing process. Never pick the skin off - allow it to come off on its own, or you can cause bleeding and additional scabbing. Sorry for so much info...when mites hit my colony I had no idea what hit me until a few of my dragons were covered with scabs and going to the vets. Hope some of this helps!
Good luck! It took me months to get throug it...but with patience and tender loving care so will you!!!
