Well its good the shop is treating him & not sent him home with you, when its cleared up and you do take him home, keep him away from the other snakes for a good couple of weeks, just to make sure the mites are gone & if you do touch him make sure you use that special hand gel, sorry cant remember what its called, before you touch any other snakes or anything else for that matter. Good luck with him, be nice to see a pic of him.
