Natural Habitat

Damp environments with high humidity, fungal growth, or rotting organic matter, often found in kitchens, bathrooms, or stored food products.

Diet & Feeding

Primarily feeds on mold, fungi, and yeast, but also consumes high-protein stored foods like cheese, seeds, and grains.

Behavior Patterns

They congregate in large numbers where moisture and food are present, appearing as 'moving dust'. They have a very rapid life cycle when conditions are warm and humid.

Risks & Benefits

They do not bite humans or pets but can cause 'grocer's itch' (allergic dermatitis) or respiratory allergies in sensitive individuals. They can contaminate food supplies.
