Overview
Indian meal moths are the most common stored product pest in homes. They infest grains, cereals, nuts, dried fruit, pet food, and other dry goods. The distinctive two-toned wings help identify them.
How to Identify
- Wingspan about 1/2 to 5/8 inch
- Gray inner wing portion, copper/bronze outer portion
- Distinctive two-toned wing pattern
- Larvae are cream-colored with brown heads
- Webbing in infested products
Behavior
Adult moths fly at night and are attracted to lights. Larvae spin silken webbing in food products. Infestations often originate from products brought home from stores.
Habitat
Found in pantries, cabinets, and wherever dry foods are stored. Larvae can crawl considerable distances to pupate, appearing on walls and ceilings.
Diet
Larvae feed on grains, cereals, flour, cornmeal, rice, nuts, dried fruit, pet food, bird seed, and similar dry products.
Reproduction
Females lay 100-400 eggs on or near food. Development from egg to adult takes 4-6 weeks in warm conditions. Multiple generations per year.
Distribution in the Southern U.S.
Common throughout Texas, Oklahoma, Louisiana, and Mississippi in homes and food storage facilities.

Warm Southern temperatures accelerate pantry moth development. Infestations can establish quickly in hot pantries.
