Indian Meal Moth

Indian Meal Moth

The Indianmeal moth is the most common pest of coarsely ground flours such as whole wheat and cornmeal. They are also a common predator of shelled and ear corn, broken grains, dried fruit, crackers, nuts, dry dog food, peas, and beans. Indianmeal moths are well known for spinning large amounts of webbing that further contaminates food products. These webs, forming cocoons, are usually found in higher elevations, commonly in the crevice where the ceiling and drywall come together.

Indianmeal moth adults are multi-colored with reddish brown and a coppery luster. They also have pale gray wings with a wingspan of about ¾-inch. The reproduction period usually begins in the springtime. Females normally lay their eggs at night and are capable of laying eggs in small amounts or great masses producing between 200 – 400. Their complete life cycle takes between six and eight weeks.
