Scientific Name: Curculionoidea

Weevils are actually beetles belonging to the family Curculionidae. They are less than a quarter of an inch long in size. They are plant eaters and the larvae of most species will damage crops, making them pests. They prefer warm weather and can often be found in dry foods like nuts, seeds, and grains or grain products like flour or pancake mix.

What do Weevil's Look Like?

Management and Prevention of Weevils

To prevent adult weevils from entering your home, install screens on your windows and doors and repair any cracks around entryways including your crawl space. Weevils are attracted to moisture and can be trapped using shallow pans of water – however this will not catch all weevils. If you find weevils inside your home, you can remove them quickly with a vacuum or dust pan. Just make sure you empty the bag outside to prevent the weevils from re-entering your home.

Publicly available insecticides are not effective or necessary to use against weevils. If you have an infestation, contact a pest control specialist to help manage the infestation and provide a customized treatment plan to protect your home.
