sadly none. nothing is fully effective and nothing so far will make it totally go away some will suppress it for a bit but then it comes back, and sometimes with a vengeance. also remember aw is HIGHLY contagious. so any other reptiles you might have be so so so careful with just in case as well as wildlife can be affected if they are let to roam outside and they in fact do have it. it remains contagious even when no signs are seen also from our experience with this.
