Pretty sure they came in on the aspen, and were defo snake mites The bag was bought from a specialist reptile store, and they had a mite problem themselves when i went in the next week. Mites appeared 5 days or so after adding the new batch of aspen.Only had the snakes in my house for 2weeks, as i was looking after them for a friend, so never had any other pets/reptiles in the house for years, so the only logical source is the aspen, i guess??? Had them on newspaper since with no return of mites
