Grain moths are flying stored-product pests also referred to as pantry pests.  Their coloring will depend on the specific species, but in general, they are cream colored with brown to brownish-reddish markings.  Their larvae are lighter colored and grub-like in appearance.

Grain moth behaviors

If there is a grain moth infestation in your home, you might see the adults flying around your home, especially in the kitchen and pantry areas.  Grain moths feed on a large variety of food including: flour, cereal, pasta, nuts, spices, chocolate, dried flowers, dried fruits and vegetables, dry pet food, and bird seed.

The adults will mate and the female will lay her eggs in a suitable food source.  When the larvae hatch they will feed on, pupate in, and contaminate that food source.  Signs of a grain moth infestation include:

  • Webbing along the corners of packages or on the product itself
  • Small holes in the packaging of food and dry goods - especially flour and cereal which will develop an unpleasant odor
  • The presence of adult grain moths or their caterpillars in your kitchen area.

Grain moths are more often than not introduced into your home through infested products that you purchase from stores.  Adults may also get into your home while foraging for food sources through gaps and holes found in screens or around exterior windows and doors.

Are grain moths dangerous?

No, grain moths are not a dangerous; they are more annoying than anything else.  Grain moths do not bite or sting and are not known to transmit any diseases to people; however, their presence in food means that it is contaminated and will need to be thrown out.  Eliminating a problem with grain moths in your home can be tricky and should be handled by a professional.

Grain moth prevention tips

When it comes to preventing grain moths and other stored product pest from taking over your pantry, you must focus on inspection, proper storage and exclusion.  Carefully inspect food packaging for any holes or rips; do not purchase items that have been damaged.  You should also inspect your pantry and cupboards for old and/or expired food and toss any that are no longer good or that are not stored properly.  Store dry goods in sealed glass or plastic containers rather than their original packaging.  Same goes for dry pet food and bird food.  Repair or replace torn window screens or screen doors and seal any cracks, gaps or openings on the exterior of the house.
