Weevils feed off stored materials like flour, cereal, and rice and reproduce quickly, making an infestation take over quickly. The most common way they enter homes is by coming in with already-infested food items. Adult weevils look for shelter when it is hot and dry outdoors, coming in through tiny cracks. Food infested with moths, weevils, or other beetles can be a major nuisance, but experts say there’s no need to panic.

Weevils can enter food by laying their eggs inside grains and seeds, which hatch and develop into larvae within the food supply. Improperly stored foods, cracks in walls, or food packaging can also cause weevils to enter your home. According to Wang, they can fly into your home or come in through contaminated food.

Where Do Pantry Weevils Come From?

Weevils are pests commonly found worldwide, especially in warm and moist environments. They tend to invade homes during hot, dry weather, typically entering through cracks around doors, windows, or the foundation. Infestations often start outside in areas like fruit trees and gardens. The pantry weevil, known for its peculiar appearance, is particularly problematic as it primarily feeds on grains, earning the moniker "flour bug." These pests enter kitchens by laying eggs in food sources, specifically flour or wheat products. Once the weevil eggs hatch, larvae develop within the food, leading to infestations.

To effectively tackle a weevil problem, it's essential to first identify any infested food items in your pantry. Contaminated products should be discarded to prevent further spread. Proper food storage is critical; keeping flour in airtight containers can help minimize the risk of infestations. Weevils may also enter homes through contaminated food or by flying in through open windows.

Historically, weevils have been present for thousands of years, with evidence found in ancient Egyptian tombs. While they can be troublesome, they are generally not harmful to humans. With cooperation from farmers, government officials, and scientists, certain weevils, like the boll weevil, have seen a decline, demonstrating effective management strategies. Understanding where weevils come from and how to store food properly can help maintain a pest-free pantry.

How To Bug Proof Your Pantry?

To effectively prevent pests from invading your pantry, consider the following strategies:

1. Periodically deep clean your pantry to eliminate potential hiding spots for pests.
