The white paper towels will help you assess the possible mite situation- look for tiny specks in the water bowl- they hide very well on a snake's body- especially around the eyes, in nostrils, on the chin, & under scales anywhere, including the "vent". I would avoid treating for mites unless you're sure they exist- and only snake mites really matter. Wood mites sometimes occur (especially with wood & mulch decor) & they're annoying but won't hurt the snake. Sometimes the warmth & humidity attracts other insects too, like fungus gnats. Also, IF you find snake mites, discard ALL decor made of wood as it's porous & both mites & their eggs will be hiding & residing there.
BTW, How long have you had this snake? Is is your only snake? Here's hoping you don't have any snake mites. They are tiny- like a pinpoint- & may appear black, brown or red when they've been sucking blood from your snake. They also move- unlike the specks that "came with your snake"-![]()
