Do not freak out, but you almost certainly have a few dozen arachnids that live, eat, crawl and leave their detritus on your face. They are known as eyelash mites or Demodex, and just about each adult human has them. So, there is nothing wrong with you. These creepy-crawlies are mostly transparent, microscopic in size, eight-legged, and eat sebum (greasy oil on your skin). Definitely, face mites have the closest connection with humans.
