The Indian Meal Moth is a very common insect found in stored products within the home and in stored grain on farms, in warehouses, and grocery stores. In the home, Indian Meal Moth larvae feed on any grain product (flower, cornmeal, oatmeal, etc.), seeds (including bird seed and dried beans), nuts, chocolate, dried fruit (such as raisins), and even dog food. These larvae often leave their food supply when they are ready to spin their cocoons and they may wander about in search of a suitable place to pupate. They are frequently found in unsuspected places because of this wandering behavior. Control of any stored food pest requires locating and eliminating infested item(s). All potentially infested foods should be checked. The insects may be in unopened boxes or containers. Infested items can be thrown away or salvaged by freezing for 1 week or heating in a 140 degree oven for 15 minutes. Empty and thoroughly vacuum clean cupboards or shelves holding infested items, paying particular attention to cracks and corners. Vacuum cleaning picks up hiding insects and spilled or infested material. Empty the vacuum cleaner bag after use to prevent re infestation. Insecticide sprays are not recommended for controlling insects in stored food cupboards.
Chem-Wise usually does not need to spray for Indian Meal Moths. The customer must first follow the following outlined steps, which in many cases will eliminate the problem:
- Thoroughly clean cupboards with a strong cleanser: repeat this process two weeks later
- After cleaning, thoroughly vacuum cupboards paying close attention to cracks and corners
- Store pet food in air tight containers: throw out old food and clean the containers before adding a new bag
- Store susceptible foods in seal able glass, metal, or heavy plastic containers
