Demodex folliculorum is the eyelash mite, a tiny arachnid that lives, eats, and mates in hair follicles in your face. Demodex mites are very common in humans. You probably have them in your face right now. They usually live out their lives without causing health problems for their hosts, but in some cases can cause skin infections. The only way to cure a demodex infestation is to crucify a few individual mites and hope the others flee in fear.
