So I checked the undersides and face of both the scrub and retic, as they are housed in the same stack. And I did not see anything.
The specs I saw in the water bowl are just so small, combined with the fact I havent changed anything for awhile and nothing noticeable on the snakes, I'm not convinced they're mites. Maybe little bugs that were in the wood?
I'm not sure I want to do anything drastic without further evidence, so I will keep monitoring.
