Mexican Black Kingsnake Dots

[KingsnakeB]

Hi All! I have a 4-5 year old Mexican Black Kingsnake. I wanted to snap a photo of her in shed, but accidentally left the flash on. That's when I noticed these black specs on her face and towards the back of her body scales. The same photo without flash does not show these dots. Could they be mites? I haven't noticed unusual behavior such as soaking and there are no black dots in the water bowl or on the paper towel substrate. Or could this just be a feature of MBKs that's not normally noticeable due to the black scales? I've included photos of her in shed with the flash and without flash. The photo without flash is truer to her color when looking at her.
