Pantry moth traps rely on pheromones to attract males and cannot be duplicated using readily available household products. To remove the infestation through do-it-yourself means, clean the pantry and discard any contaminated food. Make a sachet filled with bay leaves, cinnamon sticks, eucalyptus leaves, lavender, and peppercorns or wormwood, and leave it in the pantry. The aroma discourages the moths from returning.
- Clean the pantry
Vacuum the shelves, and use a hose attachment to remove dirt from between any cracks. Dispose of any debris, moths, larvae and eggs in an airtight bag to prevent the pests from escaping. Place the bag in an outside trash bin. Scrub the pantry shelves with soap and warm water. Avoid using insecticides to kill pantry moths.
- Dispose of contaminated food
Immediately throw out broken or cracked food packages in an airtight bag. Seal any remaining food tightly to prevent infestation. To eliminate lingering adult moths and larvae, keep food sealed for at least a month, which is the length of their life cycle. Store food in the refrigerator if possible.
- Make the sachets to prevent re-infestation
Fill a small cloth bag with a combination of bay leaves, cinnamon sticks, eucalyptus leaves, lavender, and peppercorns or wormwood, and put the sachet in the pantry. Hang dried lemon peels from the ceiling for another natural deterrent. Place bay leaves in flour canisters in the corners of the pantry and near food that might attract pantry moths.
