Natural Habitat

Found indoors worldwide, specifically in humid environments and soft surfaces like mattresses, pillows, carpets, and upholstery where humans and pets spend time.

Diet & Feeding

Primarily feeds on dander (dead skin cells) shed by humans and animals.

Behavior Patterns

They are photophobic (avoid light) and thrive in high humidity (above 60%). They do not drink water but absorb moisture from the air. Their life cycle from egg to adult takes about one month.

Risks & Benefits

They do not bite or sting but are a major source of allergens. Enzymes in their waste (feces) and decaying body parts can trigger asthma, allergic rhinitis (hay fever), and eczema in sensitive individuals.
