About Pantry Pests

Pantry pests, also known as stored product pests, get their name because they often infest food stored in pantries and kitchen cabinets. These insects are often brought into the home unknowingly in items from the grocery store.

The National Pest Management Association (NPMA) recommends the following tips to prevent pantry pests:

  • Seal items: Proper food storage can go a long way in preventing an infestation. Once packages are opened, move ingredients into sealed glass or Tupperware-type containers with secure lids before storing them in the pantry or cabinet.
  • Check dates: Remember to check expiration dates on ingredients before use. Periodically sort through old items in the pantry and toss out anything that has been stored for a long time.
  • Clean often: Immediately wipe up any crumbs or spills from countertops, tables, floors and shelves. Occasionally empty the cupboards and clean them with soap and water to get rid of residue and anything that may be hiding inside.

Additionally, refrigerate or freeze bulk flour, spices, and grains both to maintain freshness and to kill insect eggs.
