Granary Weevil

Granary Weevil


The Granary weevil is small in size, about 1/8” in length.  It is reddish-brown to black in color, and it is covered with short, yellow hairs.  It is sometimes referred to as a Wheat weevil or a Grain weevil.


Location and Behavior Patterns: 

This type of weevil and most pests are attracted to cereal grains, wheat, corn, barley, and other similar items.  It can be found in nuts, bird seed, decorative Indian corn, and other dry-stored items.  The female Granary weevil can lay up to 200 eggs at a time, and since this weevil doesn’t fly, the hatched larvae will feed on all grain items around them.  

They can be found in food items located in your pantry, as well as making their way indoors through cracks in your home’s foundation, or around doors and windows.  They especially seek the indoors when it is hot and dry outside.


Once a Granary weevil infestation has been spotted, it is important for you to discard all affected food items.  Additionally, it is recommended that you vacuum the area around where the food items were stored, and discard the vacuum bag, too.  Cleaning the shelving area, with something like white vinegar, will ensure that you clean the area completely, and ward off future Granary weevils from infecting other food sources.
