If you are that concerned, I would put the snake on paper towels for more than a couple of days. That way, you can monitor the mite infestation (or lack thereof) more easily until you can be sure.

What I do is whenever I get a new animal in, I treat it for mites ASAP. No muss, no fuss.

You can PAM the Aspen too, if you want, or bake it.
