Just found some tiny, beetle-like bugs (not mites) in my sand boas tank. She's been on walnut shell bedding for the last 3-4 months (same batch) and I've never seen these before... Apparently they're nocturnal as they were no where to be seen this morning. Also saw a larval stage. They don't appear to be bothering her, but they sure do creep me out.

Has anyone ever had this happen before and /or know what they might be? I don't have a camera with a macro lens or I'd try to get a pic. They are definitely insects, have 3 body segments, 6 legs, have a rounded body shape (not flat like a mite or tick) and are brownish orangish in color. They're about 2-3mm long..closer to 2. The larva are whitish Caterpillar looking guys.

I'm mainly concerned about whether or not these guys could spread outside of the tank or pose a hazard to the snake.

Thanks for your help!
