Granary weevils are a type of beetle and a type of stored pest product. They are known for their distinct snout that extends downward from their head. They do have wings, but they cannot fly, unlike other types of weevils. These pests target grain products; the female even lays her eggs in grain kernels. They are not dangerous to you or your home, only the grains in your kitchen. There are a couple things you can do to prevent them from entering your home, but if you do find that your home is infested, call Nashville Pest Control.
Appearance and Life-cycle:
The granary weevil is a brownish red color and only 1/8th of an inch long. They have a hard-shell body. Their head is longer with a snout that extends downward, which can be an easy way to identify these pests. They do have wings with four light-colored patches, but they cannot fly.
The female lays her eggs in grain kernels. They can lay up to 400 eggs at a time, but not all of the eggs hatch. The larvae are wrinkly and grub like with a whiteish color. The larvae will pupate before chewing their way out of the kernel. It takes about five weeks for the larvae to develop into adults. The adult can live about seven to eight weeks.
Habitat and Behavior:
Granary weevil infestations normally start at food processing plants. They can enter your home in food products bought at stores that are already infested with the larvae. They are mainly attracted to grains: wheat, corn, barley, rice, etc. they have also been known to infest bird seed, buts, and decorative Indian corn.
When they are disturbed, they play dead by pulling their legs close to their bodies. They will stay still for several minutes before moving again.
Level of Danger:
The granary weevil is not dangerous. Luckily, they do not bite or sting and they are not known to transmit diseases. The only damage they create is in the grains that they infest. They are considered a large threat to the agricultural industry.
Signs of Infestation:
A sign of granary weevil infestation is the exit holes they leave when they chew out of the grain the eggs were deposited in. Because they cannot fly, they stick fairly close to the infestation site.
The best way to prevent these pests from infesting your home is to inspect food products before you buy them, because that is how they generally enter your home. It also helps to put grain and seed products in sealed containers. Keeping the places where you store food clean is also helpful in preventing bug infestations.
If you think your kitchen might be infested with granary weevils, call Nashville Pest Control to get rid of them for you. They know what to look for and can ensure that all of the pests are removed from your home.
