Marks - Yeah, they were definitely snake mites. They were all over the snakes and burrowing under their scales. Took me a month and a half of soaking, PAM, and Lice MD to finally kill them all. And that was after throwing out all the cypress and putting them on paper. Never want to do that again.
Badgemash - You rock, thanks so much. That's exactly what I was looking for. =)
