Indian meal moth (larva)

Pantries, warehouses, grocery stores, and food processing facilities worldwide.

Stored grain products, seeds, nuts, dried fruits, flour, cereal, chocolate, and pet food.

Larvae spin silken webs as they feed, often matting food particles together. They crawl away from food sources to pupate in crevices or at the wall-ceiling junction.

Major household pest that contaminates food with webbing, frass (excrement), and silk; does not bite or carry diseases but causes significant economic loss through food spoilage.
