Identifying Different Types of Weevils in Your Home Identifying Different Types of Weevils in Your Home

Weevils are small insects that are often considered pests. Basically, they belong to a family of tiny beetles.  Outdoors, this insect feeds upon plant leaves, fruits, vegetables, grains and seeds. At home, it can be found in pantries that contain opened boxes or bags of cereals, flour, and nuts. Below are some of the most common types of weevils that can move into your home.

Granary Weevils

This is a common type of weevil. It comes in black or dark brown. At about 4 mm, it is noticeably smaller compared to other members of the species. Granary weevils, or grain weevils, are known all over the world because they infest most types of grains. In India, they are notorious for decimating rice harvests, so they are also referred to as rice weevils in that country. A female granary weevil lays its eggs inside grains and can have an average of six reproductive cycles every year. At home, you can find this type of weevil in your kitchen eating their way into cereal boxes or cracker packs.

Pea Weevils

Members of this group are closer to being regular leaf beetles than weevils. But just like other weevil varieties, the female pea weevil would bore deep into seeds, in this case peas, to deposit its eggs. They are known to feed on peas and even beans.

Apple Blossom Weevils

This weevil originated from Europe and some parts of Asia and North Africa. It took its name from the fact that it feeds on apple or even pear blossoms. Adult apple blossom weevils are normally 4 mm in length with long and narrow snouts. They come in dark red or brown color with white markings on both wings. They can get inside your home if the apples or pears you buy from the grocery are not thoroughly cleaned or if you live near an apple or pear plantation.

The flowers that have been attacked by this weevil will fail to develop, thus bringing down the number of fruits that can be harvested. On top of using apple or pear flowers as food, the females of this type of weevil also deposit their eggs inside. So, it will not be surprising to find their larvae or pupae in affected blossoms. During the winter season, apple blossom weevils hibernate in loose or dried out barks of apple and pear trees. They can also lie dormant among dead leaves and other debris that accumulate on the ground, then come out at the start of spring and relocate onto apple or pear trees. 

Leaf Weevils

These weevils are characterized by short snouts and metallic green or bronze scales, but at first glance they appear to be black or dark brown in color. They can grow anywhere from 4 to 9 mm and are common in gardens. As their name suggests, these weevils eat the leaves of trees like apple, pear, oak, alder, cherries and even rhododendrons. As they feed, they can also cause damage to blossoms. The good news is that leaf weevils can be easily controlled using garden pesticides.
