Natural Habitat

Indoor environments with high humidity, damp furniture, pantries, and stored products where fungi or mold grow.

Diet & Feeding

Primarily feeds on mold, fungi, and high-protein/fat organic materials like dried meats, seeds, and cheese.

Behavior Patterns

Rapid reproduction in humid conditions; they often appear as moving 'dust' or small white dots on dark surfaces. They do not bite humans but congregate around food sources.

Risks & Benefits

Non-biting, but can cause allergic reactions (dermatitis or respiratory issues) in sensitive individuals. They can contaminate food supplies and indicate a moisture or mold problem in the home.
