About a month or two after I got my first snake I found out about mite and had literally thousands of them in my ARS rack, didn't even know what they were. I found out that some of my snakes with black spots were actually pure white LOL. Those little buggers are hard to kill, I'd be devastated if I got them again. I used to clean and spray everything and I guess the Reptile spray didn't work by killing the eggs and they would all hatch out underneath the paper towels on the bottoms of the tubs and just show up out of nowhere days later. It took me about two months to finally get rid of them once and for all. Now I always watch like a hawk to make sure I don't see one. Just be careful not to directly treat the snake outside of the directions on the product, most can be lethal.
