Reddit reviews What's Wrong With My Snake (Advanced Vivarium Systems)

I tend to agree that mites can be transmitted by feeders and the What's Wrong with my Snake? book agrees.

I've also used their method with success. Basically, give the snake a bath in water with a drop or two of dish soap (per liter of water). The purpose is to drown the little fuckers. Slowly and painfully. Of course, some will try to migrate to the snake's head, so you can coat their head and neck in olive oil. Fair warning, but you are probably going to need a friend to help with this. Bathe the snake, disinfect everything with chlorohexidine, and switch to newspaper. You should do this daily until the mites are gone.

I would stay away from anything not indicated for snakes. There's been some cases of neurological damage from improper treatment.
