How do mites get in a T enclosure anyway??? I am really careful, but a couple weeks ago i had some in with my Chilean Red. Taken care of and none with the others. Are they naturally in the substrate or what? I use a mixture of peat/gardening soil (more peat). I know that if kept overly damp there is more likelihood of this. Also if it is not as well ventilated? Bluh. Damn things. I like them even less than crickets.
