Indian Meal Moths
Indian meal moths are the most common stored product pest in homes and grocery stores. Adults are small moths with distinctive two-toned wings - the inner half is pale gray and the outer half is reddish-brown or copper-colored. Larvae feed on a wide variety of stored foods including grains, cereals, dried fruits, nuts, chocolate, pet food, and birdseed. Infestations often originate from products purchased at the store that already contain eggs or larvae. Silken webbing produced by larvae is typically the first visible sign of infestation in stored products.

Key Behaviors
Indian meal moth larvae produce silken webbing as they feed, which contaminates food and binds particles together into clumps. Mature larvae leave their food source and crawl to pupation sites on walls, ceilings, and shelf edges, making them visible to homeowners. Adults do not feed and are attracted to lights, often found fluttering in rooms away from the pantry. Infestations can spread from a single contaminated product to multiple stored foods.
Risks & Concerns
Indian meal moths contaminate stored food with frass, webbing, and larval skins, rendering products inedible. Infestations spread rapidly through pantries as larvae move between products. They do not transmit disease but cause significant food waste and homeowner distress. Commercial infestations in grocery stores, warehouses, and food processing facilities can result in product recalls and regulatory action.
Identification Tip
The two-toned wing pattern with a pale base and copper-reddish tip is distinctive. Other pantry moths such as the Mediterranean flour moth are uniformly colored. The larvae are often confused with clothes moth larvae, but Indian meal moths are strictly associated with food products, not textiles.
