I have seen tiny little white bugs crawling around in the substrate. Probably the only reason they are visible is because the power sun illuminates them and they stand out on the dark substrate. There aren't a ton of these things. Just randomly will spot 1 or 2 when i stir the substrate around. Anyone experience the same thing? Are they bad or nothing to worry about? I've never seen them crawling on my tegu yet either. It is a 5wk or so varnyard baby.
