Today I handled the BP I got two weeks ago, and I noticed a single, very tiny black bug crawling on its head. I picked it off, and inspected the snake for more, but did not see any. I inspected the water bowl and the substrate (paper towel) and didn't see any there either. Should I be worried, or could this be something other than mites? This is my only BP, so if it has mites, I'd imagine it was purchased with mites.
