What I do is make sure my quarantine area is set up and about 3 days before I bring the new arrival home, I spray the empty quarantine tub with PAM (Provent-a-mite). Then the day new arrival is here, set up the tub with paper towels, water dish and disposable hide (like a cardboard box). That's it. Then after 60-90 days if all is well, new arrival moves in with the collection. I've brought in snakes that had mites before and this worked great.
