Salvage foods that you do not wish to throw away by sterilizing them. Place the food in the freezer at zero degrees Fahrenheit for four or five days or heat food in the oven in a shallow pan at 130 degrees for 30 minutes to kill the eggs, larvae and weevil insects.
Remove all food items from the kitchen pantry and cabinets. Clean the surfaces with a vacuum cleaner to remove any eggs, larvae or insects. Focus on small cracks and crevices when you clean the cabinets. Throw the contents of the vacuum cleaner outside into the trash.
Examine the food in the cabinets every day to ensure that you killed the weevils. Continue to remove food items and vacuum the cabinets if you notice signs of the pests.
