Mites are some of the most tenacious and diverse animals. They are ubiquitous in this world, and most of them aren't parasitic. The ones that are usually are very picky about their host, and some can be a little more diverse. Mostly my experience and what I heard of is that an otherwise heathly snake will react quickly to mites by soaking water and compulsively rub it's face against rough surfaces despite not being in a shed. Good hygiene is the best prevention. The prevent a mite line works well, helped my friend's sav out. If you do see mites ever, switch to paper towel for a couple months.
