I had mites on my first ever ball python. It was a small infestation, but he had a couple of them lodged in the eye sockets, just like in your picture.
While everything else died within a single treatment, I had a bit more trouble with those.
Ultimately, we ended up rubbing a moist qtip veeeery gently, from behind the eye, trying to push them out. It took a bit of patience, but it worked well.
