The first move would be to spray the outside or exteriors of all the cages in your collection with a permethrin spray such as PAM, Equate, etc. This will keep the mites from spreading through your collection. See the entire thread started by MsPony on Dec. 5th for more details on how to deal with the mites that are currently on this snake. Once the mites are eliminated and after a shed or two, this one should recover without incident.
