So u poked my head in my Tegus enclosure this morning to mist and change his water and I noticed that there are little white bugs sitting around and jumping on the top of the water. What the hell could they be? Mites? I thought mights were black? I have never had this issue with any of my animals and I need advice. Where did they come from? How do I get rid of them? Here's some info..... His substrate is topsoil and sand mix (about 3 or 4") and then 8" of cypress mulch on top. Tegu is about 33" 1600g and eats/sleeps/poops/sheds with no issues. I'm terrified at the prospect of changing out all of his substrate. I'm not noticing any of these things outside of his dish. The water is about 2 days old.
