Weevils usually get into your house by hitching a ride in your groceries. Adult weevils burrow into rice and other grains to lay their eggs, so you may not know you've brought home pests until they hatch and crawl all over your pantry! The fastest remedy for an infestation? Purge. Get rid of any unsealed dry foods, including flour, cornmeal, oats, rice, pasta, and prepackaged items that don’t have sealed pouches inside. Then, throw away all the boxes of sealed items like soup mixes or gelatin. Even if weevils don’t eat these items, they could enter the boxes to hide, only to reemerge later to contaminate your food. After you've tossed the affected foods, clean the pantry shelves and spray a household insecticide around the area. Once the liquid has had a chance to dry, you can restock.
