Description:

Weevil species occur in a wide range of colors and body shapes. Many are slender or oval-shaped insects. Depending on the species, weevils range in size from about 3 mm to over 10 mm in length. They are usually dark-colored—brownish to black. Some have scales or shiny hairs covering part of their bodies. The most distinctive feature of weevils is the shape of their head. An adult weevil has an elongated head that forms a snout. The mouth is at the end of the snout. Some weevils have a snout that is as long as the body.

Habits:

Like their appearance, the habits of weevils also varies by species. Some lay their eggs in the spring near the host plant, the larvae will then hide underground and feed on the plant’s roots. Some larvae will stay underground during winter and surface as fully grown adults in the spring. They feed on plants both in the larval and adult stages. They can be extremely detrimental to the livelihood of crops. Some weevils also attack stored grains and seeds, the most common of which is known as the rice weevil.

Defense:

• Most likely, homeowners seeing weevils are dealing with the stored product species.
• The most important control methods are to find the infested material and eliminate it.
• Careful inspection of items before purchasing can help prevent getting a new infestation. Products with holes or signs of damage on the packaging should not be purchasedA pest control professional should be contacted for assistance.
