Just thought I'd mention that I did the oil treatment with Sly when we first got him and he had mites. What I did was every other day I would remove him from his enclosure, rub him down with olive oil, put him in another container, clean his enclosure thoroughly, replace paper towel substrate, new disposable hide, and clean water in a clean dish. Then I would return my attention to the snake, rubbing him down again with olive oil, just letting him move through my fingers for several minutes, then I rinsed him with warm water for a couple minutes and returned him to his now clean enclosure. If I remember correctly, the egg to mite cycle is about 3 days and, of course, the oil does nothing to the eggs, which is why I opted to treat Sly every 2 days. While rubbing him down with the oil my hands would eventually be covered in dead mites... I know, gross, but it was obviously working. I did this for about 3 weeks and haven't had a recurrence yet. This was about 7 years ago. He was a yearling at the time and I just didn't like the idea of using poison on him. May do things differently now, but the oil did work and work well.

Geez, I hope saying that doesn't jinx me!
