Weevil bugs, sometimes referred to as "weebles," love to infest busy kitchens. Weevils commonly find comfort in jars of flour or grain and rarely inhabit other food sources in your kitchen. Female weevils often lay their eggs in grain, so even if you buy weevil-free flour or wheat, there could be weevil eggs present that you don't know about. Because of this, it's important to regularly inspect your food to make sure that no dormant weevil eggs have hatched.
Inspect your food before you buy it, especially if you buy food in bulk. Check for signs of weevils. Look for small black specks in bags of grain and ensure that all bags of flour or wheat are properly sealed.
Store your grains in a sealed container in a cool, dry place. While large amounts of flour or wheat can be stored in large, plastic containers, grain products should ideally be stored in the freezer where weevil eggs cannot hatch.
Wipe down your kitchen counters after use with a damp cloth and regularly inspect your cupboards for signs of pests. One of the simplest ways to keep your kitchen free from pests, including weevils, is to make sure that your counters and floors are crumb-free.
Discard food once you notice a weevil. Even if there is only one weevil in the bag of flour, it's important to discard the entire bag. If you see one insect, the chances of there being more present are high.
While some bakers believe that placing a few bay leaves in flour will repel weevils, there is currently no scientific evidence to confirm this theory.
