It's my understanding that snake mites are black. It's possible that a mouse would have some external parasite on him (fleas or mites) but if so, they won't bother your snake. If they came from the mouse, you should be able to just clean out the enclosure really well and not worry about it. But I'd keep a clean, white substrate (like paper towels) in there until I knew for sure. (If it were me)Originally Posted by bonez
