Natural Habitat

Human skin, specifically within or near hair follicles and sebaceous glands on the face (nose, eyebrows, eyelashes).

Diet & Feeding

Dead skin cells (corneocytes) and sebum (skin oils) produced by the glands.

Behavior Patterns

They are nocturnal, emerging from follicles at night to move across the skin surface to find mates. They spend their entire life cycle on human skin.

Risks & Benefits

Generally harmless commensals and part of the skin's normal microbiome. However, overpopulation can be associated with skin conditions like rosacea or blepharitis (eyelid inflammation).
