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 or discard the vacuum cleaner bag after use to prevent reinfestation. Insecticide sprays are not recommended for controlling insects in stored food cupboards. Washing shelves with detergent, bleach, ammonia or disinfectants will not have any effect on insect pests. As a precaution against reinfestation, you may want to store susceptible foods in sealable glass, metal or heavy plastic containers or in the refrigerator or freezer until you are convinced the infestation is gone. After completing these tasks, a pheromone attractant such as Pantry Patrol for Beetles or Allure for Moths is recommended for complete control and monitoring and trapping the male species.
