I saw a tiny white bug on my ball python?

I think they're called tan mites, but I'm not sure. It was extremely tiny, and was on her neck.
I'm assuming it (or they, I should say; if there's one, there's more) came from the Aspen shaving substrate?
I just fed her, so I can't give her a bath for a couple of days. I can clean the enclosure out then, but I'm only going to have to put in more shavings. I am building her new enclosure this weekend, and after that I'll go bioactive (I have to order everything online; there are no places around here selling the necessary supplies, so it'll take another few days, and I can't order until Monday). Then I'll have a new substrate, springtails (I read somewhere that they kill mites?), and hopefully isopods.
Until then, what are your suggestions?
Thanks in advance.

If you're wanting to go bioactive, you might want to wait until your snake's mite-free. Think of it like giving yourself the best chance of succeeding.

There are some other threads going on right now about mite treatments; I think you'll just want to use paper towels as substrate for the time being. They might have come in on the aspen, but fortunately you can put some on a pan and bake it on a low setting (around 200-250F) for a few hours. That should get rid of any mites hiding in there.

You can use this opportunity to let your new setup grow in and let your isopods and springtails get their numbers up for when your snake is ready to be added.

Snake mites are small black specs. A white/tan mite is probably from the substrate then still a good idea to get rid of the substrate but it shouldn't hurt your animal. This is why a lot of people bake their wood substrate.

Thank you! I will try that. I didn't realize the aspen shavings should or could be baked. No one mentions these things when you're doing research lol :/.
Pretty sure the supplies will be coming this week or next, as we've finally ordered everything, so I'll be able to switch everything over then.
