We’ve had this discussion on here many times. Some don’t believe ball pythons soak for any other reason then mites. Some believe that ball pythons should be provided with a bowl to soak in in case it chooses. I myself have an occasional soaker, and seen one or two others take a dip now and then. And it’s harder to observe the ones kept in racks and tubs. I keep in tanks, so for me it’s easy to see. But again it never ever hurts to double make sure you don’t have mites or a possible husbandry issue. But yes, some will take a soak if provided the option. Hope this helps. Also make sure you check around the eyes and nostrils/heat pits when looking for mites.
