The Indian meal moth is one of the most common and troublesome of the moths infesting stored products. The caterpillar stage of this insect will feed on a variety of grains, meal, breakfast foods, dried nuts, seeds, chocolate, powdered milk, and especially dry pet foods.
This stage is a small, light-colored worm that produces dirty webbing that contaminates the surface of the food. After feeding, mature worms (about 1/2-inch long) often leave the food and spin a small silken cocoon in cracks and secluded places. They emerge from their cocoon as adult moths that will lay eggs and re-infest food.
