  2. Indian meal moths develop in many kinds of stored foods. Coarsely ground grains and cereal products are commonly infested.

  3. Females lay tiny eggs (ca. 0.5 mm) on or near potential food items. The newly hatched caterpillars (larvae) seek out foods and begin to develop

  4. When feeding is completed the caterpillars usually wander from the food and search for a place to pupate. • Coccoons are most often located in cracks or confined spaces, such as the junction between walls and ceiling.

  5. The adults emerge, mate and lay eggs. • Since the moths do not feed they usually survive little more than a week. • During this time the female may deposit over 200 eggs, laid either directly on food or in crevices adjacent to the stored foods on which they feed.

  6. Control • The first, and most critical, step is to identify all sources of infestation. • Infested material should be immediately discarded, used up, or somehow treated to disinfest. • Heat to 120-140 F for 20 minutes • Deep freeze for a couple days

  7. Clean, clean and more clean • thoroughly clean areas where food was stored • thoroughness of the cleaning is important primarily to eliminate food for surviving insects to feed on • moths must be denied access to all food sources for the length of time that is required to complete the pupal stage plus how long the adult life span can be. A month should be adequate to cover this period.

  8. Use of insecticides within the pantry area is not recommended and will normally do little good.

  9. There are available traps for Indian meal moth that are baited with an attractant known as a sex pheromone. • This is the chemical used by the female Indian meal moth to attract males. • As mated females are not captured, they will continue reinfestation.
