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

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
