Indian Meal Moth Life Cycle
Female moths deposit eggs directly onto grains or similar foods. They lay 100 to 300 eggs at a time, and larvae begin to hatch as early as two days to two weeks after.
The larvae then feed on the fine materials within the grain. After anywhere from six to eight weeks, pupation begins. Adults emerge between 15 and 20 days later.
Adults live between 5 to 25 days.
The entire life cycle completes within 40 to 55 days, and seven to nine generations occur in a single year.

Both in homes and grocery stores, the insects render a costly amount of product unfit for consumption by humans and pets alike. Indian meal moths frequently travel into homes in infested bags of dried pet food and birdseed. The larval stage is responsible for damage to stored products when they spin massive amounts of silk that accumulate fecal pellets, cast skins, and eggshells in food products. The adult moth causes no damage.
