Indian Meal Moth


Indian meal moths are one of the most common stored product pests found in homes, food processing plants, grain storage and processing facilities. The larva prefer to feed on coarsely ground flour and meal but also commonly feed on whole grains, dried fruit, nuts, chocolate, beans, crackers, dry dog food and more.

The larva produce a silky web over the surface of food materials. This webbing is a tale-tale sign that most homeowners notice first. However, some homeowners will notice the adult moth flying around the pantry and kitchen areas.


Females lay 100 to 400 eggs over an 18-day period at night on the larval food source. The life cycle lasts from 25 to 135 days. Usual there are four to six generations per year depending on the food supply and temperature.


Indian meal moth control starts by identifying the infested product and the breeding sites. Indian meal moths are attracted to light so reducing the amount of night time lighting will help.

All products that are infested should be immediately removed and destroyed. Utilizing plastic, sealed container for storage will assist in stopping the spread of these pests.

Shelves, cracks and crevices should be vacuumed to remove webbing and debris.

Theses areas should also be treated with a residual product.
