Mites are an external parasite, and are unlikely to just show up due to stress when an animal moves - they don't really work by coming out from inside the snake, which is what seems to be getting implied... A snake can pick up mites from a visit to a store, or a friend coming over who visited another place that had mites, etc, etc, so it's not always that a particular place is bad or has an infestation... The snake could also have had very young or small mites when you first purchased her, and while you've had her for a few days, they've fed and grown and gone from being a nearly invisible problem to a very visible issue.

Hopefully the shop owner can help you out with a discount on treating your snake; here is an article to help you with treating them thoroughly and ensuring that once you get rid of the mites, they're gone for good. http://lllreptile.com/info/library/c...h-snake-mites/

Also, here is a video along the same lines. I highly recommend treating both the snake and the enclosure; it's the best way to ensure both snake and cage are completely free of mites by the time you're done.


Good luck!
