Using Predatory Snake Mites

[jinhomyung00]

I just ordered some predatory snake mites for my new and first snake (baby corn). I noticed the other day he had black spots on his belly and around his eyes so I did my research and found out it was mites. He is currently in a 10 gal with aspen and a couple hides, so I removed everything cleaned out with disinfecting wipes and then with wet paper towels and I let dry. He is currently inside with a water dish and paper towels. Once I receive the predatory mites can I put new aspen along with all his hides back into his tank? Please help, thank you so much!
