I think, in rare cases, it is possible to get mites from snake bedding. The family owned pet store I buy my feeders from got in a shipment of infested baby balls and when I was checking them out I noticed the mites and suggested to the owner that he get some PAM since it was obvious the mite spray he claimed to be using was not working. The setup sits right up against another set of shelves where the owner keeps his snake bedding. I suggested moving it away, but I think in a case like that it's possible.

Sadly, I don't think you can get PAM in Florida anymore. So if I end up with mites...I'm in trouble. I have never had them *knock on wood*, thank goodness, but it's definitely something I look out for.
