There is only 2 that I can see and it's on his eyes?? There is none on his body.. would they spread??

I have him on lignocel (loose substrate) should I take him off? I have never encountered mites before so I don't know what to do, 2 of my snakes (this one and a hatchling corn snake)are kept side by side on a large heat mat?

Could you advise me what to do please as I don't want them all catching these filthy bugs..
