Rice weevils attack whole grains such as wheat, corn, barley and rice. In homes, infestations are generally found in bird seed, nuts, decorative Indian corn and, in rare instances, in old pasta stored in cupboards. The rice weevil and its close relative the granary weevil do more damage to stored whole grains worldwide than any other pest.

Primarily whole grains, but also beans, nuts, cereals and fruit.

All products containing whole grains need to be inspected, along with decorative items such as Indian corn and shadow boxes containing seeds. Discard all infested packages and products. Clean spilled grain and infested cabinet areas using a vacuum followed by soapy water. Store all dried food goods in a glass or plastic container with a tight lid to limit spreading if one food becomes infested. Consider storing cereals and similar foods in the refrigerator to limit stored pantry pest problems.
