Stored Product Pest Identification

What are stored product pests?

Stored product pests are those insects (beetles, moths, and weevils) that feed on or reproduce inside packages of whole or processed grains. They are problematic inside any structure where there are suitable food sources. Examples of stored product pests that live successfully throughout Maryland, Washington, D.C., and Northern Virginia are confused flour beetles, Indian meal moths, grain weevils, and beetles.

Are stored product pests dangerous?

Stored product pests are not dangerous to people - they do not bite, sting, or transmit disease-causing pathogens. However, stored product pests do cause a lot of damage. They pose a significant risk to our food sources. The larval stage of stored product pests is the stage of development that causes the most damage. After hatching, the larvae feed on the food source they were born in. These pests contaminate food sources, creating a substantial economic loss inside large food storage and processing facilities.

Why do I have a stored product pest problem?

There are a variety of ways that stored product pests find their way inside. Two of the most common ways include:

1. Adults find their way into structures through open windows or doors, torn screens, or openings in exterior walls, initially attracted to a building by its outdoor lighting. 
2. Bringing home products purchased from the store that are already contaminated with their eggs or larvae.

Where will I find stored product pests?

Stored product pests live and breed wherever there is a suitable food source. Kitchens, pantries, basements, attics, and closets are all places where these destructive pests feed and reside in homes and businesses. You may also find adults resting on walls, ceilings, or window sills. Stored product pests feed on and damage a variety of things, depending on their species. Common sources of food include flour, cereals, dried pasta, crackers, chocolate, dried milk, birdseed, dried fruits, dry pet food, and cake mixes.
