Rice Weevils are among the most serious and invasive pantry pests. These insects are a larger problem throughout the southern United States, but can be found everywhere. They target food supplies, specifically whole grains like wheat, corn, oats, etc. Without treatment, they can ruin entire food storage supplies.

Characteristics

The rice weevil is small, 1/10 inch (2 to 3 mm) and stout in appearance. It is very similar in appearance to the granary weevil. However, the rice weevil is reddish-brown to black in color with four light yellow or reddish spots on the corners of the elytra (the hard protective forewings). The snout is long (1 mm), almost 1/3 of the total length.

The head with snout is as long as the prothorax or the elytra. The prothorax (the body region behind the head) is strongly pitted and the elytra have rows of pits within longitudinal grooves. The larva is legless and stays inside the hollowed grain kernel. It is fat with a cream colored body and dark head capsule.

Harborage

Like all pantry pests, these bugs make their homes in pantries, basements, and anywhere with food storage. The less likely you are to interact with the food, the more likely they are to try and eat it and make a home there.
