Who knew we had these living on our face?
"It might give you the creepy-crawlies, but you almost certainly have tiny mites living in the pores of your face right now.
They're known as Demodex or eyelash mites, and just about every adult human alive has a population living on them.
The mostly transparent critters are too small to see with the naked eye. At about 0.3 millimeters long, it would would take about five adult face mites laid end to end to stretch across the head of a pin."
Although they look like fat worms they are actually realted to ticks and distantly to spiders.
People in different parts of the world have different face mites. Mostly our immune systems can keep the numbers in check. But rarely they do cause problems for folks.
