What Do Weevils Eat?

Beans

• The bean weevil is not technically a weevil, but is closely related to a beetle. They are referred to as weevils, though, because they are similar in appearance. They usually get into the beans while still in the field. Sometimes perfectly normal-looking beans are infested. These bean weevils can then continue to breed in dried beans in pantries. It is not uncommon for a homeowner to pull out a bag of dried beans and find these weevils.

Seeds

• Weevils that feed on whole grains or seeds are generally granary and rice weevils. These weevils are a dark, red-brown color. These weevils are generally found in large barn warehouses as they feed on whole grains, but can also infest the home. They can be found in popcorn, birdseed, Indian corn and nuts.

House Plants

• Root weevils can be found in both indoor and outdoor plants. The most common types of root weevils are the black vine root weevil and the strawberry weevil, which attacks strawberry plants. They generally attack the roots and leaves of a plant, leaving the leaves with an irregular edge. These weevils are attracted to water. A natural way to get rid of these pests is to place a dish of water down near a plant at night. The weevils will be drawn to the water and end up drowning in the dish.

Dried Foods

• If a weevil is found in the home, it is usually feeding on a variety of dried goods in the kitchen pantry. A homeowner will want to inspect her flour and cereal stores, along with any other dried foods. A person can tell if a weevil has been in a store of food if the individual pieces of food are stuck together by strands, much like a nearly invisible cobweb.
