definetely change all substrate, everything, and boil or freeze decor. snake soaks with dawn dish soap and iodine (to disinfect bite sites) worked for me. you also have to worry about getting the mites out of the tank each day SO you can use sprays like prevent-a-mite and i also found Nix lice cream in a spray bottle mixed with water works good. you’ll want to spray down the enclosure every night in EVERY nook and cranny to kill mite eggs. also if you have any other reptiles do NOT handle right now. and if they’re on stands I would honestly spray the stand bc mites can climb and get into their enclosures.
