They can also be problematic in homes when they are accidentally introduced through infested products that are purchased at stores and are brought into the home. Adults are attracted to light and may enter a home through gaps found around windows and doors while foraging for food.

Indian meal moths infest a variety of dry stored food products including dried fruits, grains, seeds, granola, graham crackers, nuts, chocolate, candies, bird seed, dog food, powdered milk, dried red peppers, and chocolate.
DIY Indian meal moth prevention and control tips
To prevent an Indian meal moth infestation in your home’s kitchen or pantry you should always check any dry goods that you are purchasing for holes or rips in the packaging. When you get items home from the store it is a good idea to remove them from their original packaging and place them into plastic or glass containers. Routinely clean out the pantry to get rid of expired items and to clean up crumbs and spills. To prevent adult moths from entering your home, caulk gaps around windows and doors and change white outdoor lights to yellow or sodium vapor lights, which are less attractive to insects.
