How to Eliminate Pantry Pests: Weevils and Moths

Pantry pests are an unwelcome reality for any home cook, often arriving undetected in bags of flour, grain, or dried fruit. The sight of small moths fluttering near the ceiling or tiny weevils crawling through a pasta jar is a clear sign that an infestation has taken hold inside your stored dry goods. Successfully clearing these pests requires a total purge of your storage space rather than spot-treating individual items. Success looks like a completely empty pantry, sanitized shelving, and a system of airtight storage containers that prevents future outbreaks. This is a project about discipline as much as it is about cleaning.

1. Empty Everything First. Remove every single item from your pantry, cupboards, and shelves. Place everything on a table or island to facilitate a thorough inspection of each container.
2. Spot Infestation Signs. Open every box, bag, and container to search for webs, larvae, or adult insects. Discard anything that shows signs of infestation, including packaging that has small holes or sealed plastic bags that look suspicious.
3. Hunt Hidden Eggs. Use a vacuum with a hose attachment to clean every corner, crack, and crevice of the pantry shelves. Pay special attention to the underside of shelf clips and the tracks of sliding doors where eggs often hide.
4. Kill Eggs with Vinegar. Wipe down every interior surface, wall, and shelf using a solution of equal parts white vinegar and warm water. Vinegar effectively kills eggs and leaves behind no chemical residue.
5. Secure the Borders. If you saw heavy activity, wipe the interior door frames and hinges with a light vinegar wash. Do not use chemical pesticides inside food storage areas.
6. Seal Everything Airtight. Transfer all remaining dry goods—flour, rice, grains, and nuts—into airtight glass or hard plastic containers. This creates a barrier that pests cannot penetrate if they happen to come home with your next grocery haul.
