Check every package of food in your pantry for weevils. If you found weevils in one package, there may be more elsewhere.
Immediately discard any weevil-infested food.
Remove everything from your pantry. If you notice spills, use a vacuum or clean them up with warm, soapy water.
Spray the shelves of the pantry with a pyrethrin insecticide if weevils are a persistent problem. Let the insecticide dry for several hours before putting items back into the pantry.
Freeze or heat grain products in case you missed a weevil infestation in your earlier inspection. To heat grain products, bake them in an oven at 120 degrees Fahrenheit for one hour.
Alternatively, you can freeze products for four days. Both of these methods kill weevils and their eggs that you cannot see.
Store food in airtight, leak-proof containers. This prevents weevils or other insects from getting to the food.
Use clear containers so you can see the food inside.
Place cloves or bay leaves on the pantry shelves. Weevils avoid the smell of both.
Things You Will Need
- Dish washing liquid
- Insecticide with pyrethrin
- Clear storage containers
- Cloves or bay leaves
- Weevils can eat through cardboard, so even brand-new products aren't safe if you already have a weevil infestation. When you buy food, immediately store it in a glass jar to prevent weevils from eating it.
