I hate mites too. I saw one on my cell phone of all places, I think I picked it up from Pet Smart earlier that day. I grabed the magnifying glass and looked over my snakes and thankfully I did not see any on them but still treated them with frontline spray diluted 50/50 on all my snakes. (reptile vet recomended) cleaned tanks, and cell phone, sprayed tanks down with frontline, let dry and air out for 30 min to an hour and used pt as substrate..... have not had a problem plus it lasts for 30 days so everytime I clean tanks i treat with frontline spray.
I even treated the dog.
