Natural Habitat

Indoor environments near stored food products such as pantries, kitchens, and warehouses; outdoors near grain stores

Diet & Feeding

Adults do not feed. Larvae feed on dry plant products including flour, cereal, grains, nuts, dried fruits, seeds, and pet food

Behavior Patterns

Adults are weak flyers and are attracted to light, often seen fluttering around kitchens or pantries in a zigzag motion. Females lay eggs directly on or near food sources, and larvae spin silk webbing as they feed

Risks & Benefits

Harmless to humans directly as they do not bite, sting, or spread disease. However, they are major household pests that contaminate stored food items with webbing, frass (feces), and cast skins
