Natural Habitat

Inhuman dwellings, specifically pantries, kitchens, and food storage facilities containing dried goods.

Diet & Feeding

Larvae feed on a wide variety of dried plant-based foods including grains, cereal, nuts, seeds, dried fruit, flour, and chocolate.

Behavior Patterns

Adults are nocturnal and attracted to light; they do not eat. Larvae spin silken webs in food sources and go through 5-7 instars before pupating in wall crevices or ceiling corners.

Risks & Benefits

They are major pantry pests that contaminate food with webbing, frass, and cocoons. They pose no direct health risk or bite to humans, but cause significant economic food waste.
