Indian meal moth (larva)

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

Stored grains, cereal, flour, nuts, dried fruits, birdseed, and dry pet food.

Larvae spin silk webbing as they feed, which can mat food together. They often crawl away from their food source to walls or ceilings to pupate.

They are a major nuisance pest that can cause significant economic loss through food contamination, though they do not bite or spread disease to humans.
