I agree its the same pet shop that infested my snake the first time when I bought him as a baby, he was riddled and they treated him for me so they must have been guilty.

Whilst I treat both snakes I put them in separate baths whilst I clean and disinfect their vivs, hoping that the soak will drown the mites, but the ones on their bodies are still there in the same place when I take them out and you can't get the damn things off when you rub them. How come they aren't drowning? Am I supposed to add something to the water? And I've heard olive oil works, do I massage it into their bodies?

Thanks as always for the advice it's very valuable to me. I hope to get them back to their former glory!
