Let’s learn more about weevils.

What Are Weevils?

Weevils are a family of beetles known as Curculionidae. They are also characterized by their elongated snouts or rostrums, which they use to pierce plant tissues for feeding and oviposition (egg-laying). Weevils are usually small in size, ranging from 2 to 12 millimeters in length, although some species can grow larger.

Do Weevils Bite?

Contrary to popular belief, most weevils do not bite humans or animals. Their mouthparts are specifically adapted for feeding on plants and stored food products, such as grains, seeds, nuts, and cereals. However, some larger species of weevils may be capable of delivering a pinch-like bite if they feel threatened or cornered.

What Do Weevils Eat?

Weevils are primarily herbivorous insects that feed on the reproductive parts of plants, including leaves, stems, flowers, and fruits. In addition, many species of weevils are notorious pests of stored grain products, where they lay their eggs and develop larvae that feed on the grains. Common types of stored food weevils include rice weevils, granary weevils, and maize weevils.

What Are the Types of Weevils?

There are over 60,000 known species of weevils worldwide, making them one of the largest families of beetles. These species vary in appearance, behavior, and preferred habitats. Also, some notable types of weevils include the boll weevil, apple blossom weevil, acorn weevil, and black vine weevil.

How Do Weevils End Up in Homes?

Weevils are found in various parts of the world, from tropical regions to temperate climates. They can be introduced into homes and buildings through infested food products, especially grains and packaged goods. Additionally, weevils are efficient hitchhikers and can also enter through small openings, cracks, or gaps in the building structure.

Signs You Have Weevils

There are several signs that indicate a weevil infestation in your home or pantry. These include finding small holes or channels in stored food products, discovering adult weevils crawling or flying around, uncovering larvae or pupae in food packages, and noticing an unpleasant odor or taste in contaminated foods.

Other Recommended Maintenance

Now that you know about weevils, let’s take a look at a few other areas of recommended maintenance. One of those is termites. It is important to know what causes you to have them in or near your home. Moisture, wood, and warmth attract termites to building structures but you can prevent them. This can be done by having regular termite inspections and sealing up cracks in the exterior.

Another is what fleas look like. They have small flat bodies, long legs, and hard plates to protect them. If you want to see if they are in your home, check bedding, carpets, and furniture.

Lastly, drain flies are a nuisance. Unfortunately, bleach does not kill them and can damage your pipes. A better way is with baking soda, vinegar, and salt.
