Demodex Mite

Natural Habitat

Hair follicles and sebaceous glands of mammals, including humans.

Diet & Feeding

Skin cells, sebum (skin oil), and occasionally bacteria associated with hair follicles.

Behavior Patterns

They live mainly in hair follicles and pores. They are nocturnal and emerge to mate on the skin's surface at night. They have a short life cycle of a couple of weeks.

Risks & Benefits

Usually harmless commensals. High populations can cause demodicosis or rosacea-like symptoms, particularly in immunocompromised individuals. They may provide minor benefits by consuming dead skin cells and excess oil.
