I'm pretty sure this is a super-low-expression paradox, letting the albino colours trough some places, and that you don't need to take the step treating for mites.

I don't have a blizzard, but i've had several snow corn snakes with these dots on them. I'm sure it's much more common than we think, it's just that in pure white snakes it's much more noticeable.

Terrible pictures, don't know what happend, but these are taken 5 minutes ago. Same little red dots
