Larvae feed on stored dry food products including grains, flour, cereals, pasta, nuts, seeds, dried fruits, and pet food.

Behavior Patterns

Nocturnal adults are weak flyers and are often seen resting on walls or ceilings. Females lay eggs directly on or near food sources, and larvae spin silk threads as they feed, contaminating stored goods.
