in three of my snake enclosures i have noticed these little tan grayish bugs on the bottoms of there hides and seen one or two crawling along the water dish. iv'e looked the snakes over and seen nothing on them(checked around the eyes, heat pits, under jaw, corner of jaw, and along body) the snakes aren't soaking, haven't seen them rubbing on stuff when they are out, and are still eating fine. Anyone have an idea as to what they could be? Iv'e been researching and the only thing i came up with was they are wood mites but want to be sure.
