How to Get Rid of Weevils in Cabinets

Updated February 21, 2017

Flour, rice, wheat, cereals and other grain-based products provide weevils a food source in kitchen cabinets. Weevils lay their eggs in seeds, flour and cornmeal along with many other types of food. Egg laying occurs in the fields, at the processing plants, in shipment or at the grocery store. Weevil eggs hatch in the grain and grow to become adults that infest cabinets and contaminate cabinet shelves and other food.

Empty the contents of the cabinet and discard any contaminated food. Inspect nearby cabinets for signs of weevils. Throw away all food that is not in a can, glass jar or sealed plastic container. Immediately dispose of the garbage in a sealed bag outside the house.

Use a vacuum hose attachment to vacuum the cabinet's shelves, sides, top and bottom. Take the vacuum outside, remove the vacuum cleaner bag and place it in a plastic bag. Tightly seal the plastic bag and place it in the trash.

Mix a food-safe antibacterial cleaning agent with hot water according to the cleaning agent manufacturer's instructions in a bucket.

Put on rubber gloves. Submerge a rag into the cleaning water and wring out the soaked rag so it is no longer dripping.

Wipe down the shelves and all interior surfaces of the cabinet. Rinse the rag often in the cleaning water. Pour the cleaning water out of the bucket and rinse the bucket outdoors. Place the cleaning rag in a zippered plastic bag, seal the bag and dispose of in the outdoor trash. Mix the antibacterial cleaning agent with hot water. Wipe down canned, jarred and sealed food. Dispose of the cleaning water, rag and wash the bucket outdoors.

Wet a clean rag with hot water and wipe down all surfaces inside the cabinet and food cans, jars and containers to remove the cleaning agent's residue. Dry the inside of the cabinet and food containers, jars or cans.


Store grains, cereals, flour, rice and pasta in tightly sealed containers or glass jars to prevent weevils from infesting other foods. Consider hiring an exterminator if you do not succeed in eradicating the weevils.


Do not eat weevil-infested foods; insects carry bacteria, which can make you sick. Avoid using pesticides or insecticides near food, as they may contain toxic chemicals.
