Natural Habitat

High-humidity environments containing organic matter, such as damp pantries, kitchens, grain storage facilities, and areas with mold or fungal growth.

Diet & Feeding

Primarily feeds on mold, fungi, and high-protein/fat stored foods like grains, seeds, cheese, and dried meats.

Behavior Patterns

They reproduce rapidly in humidity above 65%. While they cannot fly, they can be spread by wind or by hitching rides on other insects. Large infestations appear as a moving 'dust' or fine white powder.

Risks & Benefits

They do not bite humans or pets but can cause 'grocer's itch' (allergic dermatitis) and respiratory issues if inhaled. They are significant pests that cause food spoilage and economic loss in stored goods.
