I am a bit annoyed at finding mites in some of my T enclosures and need some help with a few questions I have. 1) Do they pose any risk to my Ts? 2) How do you rid rid of them? I thought that as long as the humidity was low and dry substrate you would be okay. However my B. Smithi enclosure is bone dry and there is no water dish because she fills it with dirt if I add one but tonight I found some in my P. Regalis and look in my B. Smithi enclosure and some a couple not many. 3) Is it impossible not to have any?
