Following this in case anyone else has more insight because I have noticed spots like the first image on my BP as well, except on the scales on his back. There are only about two or three on his whole body. I was worried about the possibility of mites but I don't see them anywhere else and they seem to be too small to be mites compared to photos I have seen online. They disappear from my BP when he sheds, but he eventually gets another two or three at different places on his body when some time has passed after shedding, so I am guessing it could be from wear and tear.
I also tried looking at the dots after my BP shed on his shed skin and from what I have seen it looks like tiny scabs almost? Possibly from wear and tear when climbing something or crawling through his cypress mulch bedding.
