Weevils are small, dark beetles with a distinctive snout that bore into rice, pasta, flour, lentils, and other dried goods — a common nuisance in Greek kitchens, holiday-rental cupboards, and hotel dry-storage rooms where food sits undisturbed for weeks at a time. The video above from Solutions Pest & Lawn walks through exactly how granary weevils spread and what a professional approach looks like; this article takes you through every step in plain language so you can carry out the work yourself. Whether you are dealing with a fresh infestation or trying to prevent one ahead of the summer season, the method is the same: clear, clean, seal, and monitor.
What Pantry Weevils Are and How to Spot Them
The granary weevil (Sitophilus granarius) and the rice weevil (Sitophilus oryzae) are the two species most likely to appear in a Greek household. Adults are roughly 3–4 mm long, reddish-brown to black, with a noticeable elongated snout. If you see tiny holes in individual grains of rice or pasta, or fine powdery dust at the bottom of a bag, you almost certainly have weevils rather than pantry moths — moths leave silk webbing, weevils do not.
Infestations often enter the home inside a single contaminated bag of rice, semolina, or dried legumes bought at the supermarket. Once inside, the female lays eggs inside individual grains, and the larvae develop entirely hidden from view. By the time you notice adult beetles crawling around the shelf, the infestation has usually been building for several weeks.
Why Greek Kitchens and Holiday Rentals Are Especially Vulnerable
Mediterranean cooking relies heavily on dried staples — rice, orzo, chickpeas, lentils, fava — stored in bulk, often in open bags or loosely sealed containers. In summer the ambient temperature in a kitchen or storage cupboard can exceed 30 °C, which is ideal breeding territory for weevils: their life cycle shortens dramatically in warm conditions, meaning populations double faster.
Holiday-rental properties present an additional risk because pantry stock is left untouched between guest stays, sometimes for weeks at a time. A single infested bag overlooked at the end of the season can become a full infestation by the time the next guests arrive. A structured end-of-season clear-out, described in the steps below, is the most cost-effective way to avoid this.
How to Eliminate a Weevil Infestation Step by Step
- 1
Empty and Inspect Every Item in the Cupboard
Take everything out of the affected pantry or cupboard — every bag, jar, and tin. Examine each item carefully: look for small beetles, tiny holes bored into individual grains, and powdery residue at the bottom of packaging. Any opened bag of flour, rice, pasta, semolina, or dried legumes that shows signs of infestation should go straight into a sealed rubbish bag and out of the building immediately. Do not shake infested goods into the bin inside the house — weevils can escape and re-establish elsewhere.

Freeze Suspect Items You Want to Keep
For unopened or borderline items that show no visible signs but that you suspect may be contaminated — a recently bought bag of lentils, for example — place them in the freezer at -18 °C for a minimum of four days. This kills all life stages including eggs and larvae. After freezing, transfer the goods to airtight hard containers (glass jars or rigid plastic with locking lids) before returning them to the cupboard. Freezing is the safest food-safe treatment available without any chemical risk.

Vacuum, Wash, and Dry the Cupboard Thoroughly
Once the shelves are empty, vacuum every corner, crack, and shelf edge to remove weevil eggs, larvae, and adults that may be hiding in the timber or along shelf lips. Pay particular attention to any cracks or joints in wooden shelving. After vacuuming, wipe all surfaces down with a solution of white vinegar and water (1:1 ratio), or warm soapy water, and allow the cupboard to dry completely before restocking. Moisture left behind will attract other pests. Empty the vacuum canister or bag outside immediately after use.

Restock Only in Airtight Hard Containers
Weevils cannot chew through glass or rigid plastic, so the single most effective prevention measure is moving all dried goods out of their original paper or thin plastic packaging and into properly sealed containers. Label each container with the purchase date. Bay leaves placed inside dry goods containers are a traditional deterrent — weevils dislike the essential oils — though this works best as a supplement to, not a replacement for, airtight sealing. Avoid overstocking: smaller quantities turned over more frequently give weevils less time to establish.

Set Sticky Traps and Monitor for Four Weeks
Place one or two small adhesive pantry-pest traps (available at most Greek supermarkets or hardware stores) inside or near the restocked cupboard. Check them every few days. A clean trap after two weeks is a good sign the infestation has been cleared; any new adult captures mean eggs or larvae survived and you should repeat the inspection. For holiday rentals, a brief trap check at the start of each new booking and at the end of every season takes less than five minutes and prevents the problem from becoming a guest complaint.

FAQ
- Can weevils harm humans if accidentally eaten?
- Weevils are not toxic and do not bite or sting humans. Accidentally consuming a small number in cooked food is unpleasant but not a health risk. That said, infested dry goods are considered contaminated and should be discarded, both for hygiene and because the feeding damage reduces nutritional value.
- Do I need a pest-control company to deal with a pantry weevil infestation?
- In most cases, no. Because weevils are confined to stored food and do not nest in walls or structural timber, a thorough clear-out, freeze treatment, and restock in airtight containers resolves the problem without professional intervention. You should call a licensed pest-control company if the infestation has spread beyond the pantry into multiple rooms, if you find structural damage to woodwork (which would suggest a different species), or if repeated DIY treatment has not cleared the problem after four to six weeks.
- How do I stop weevils coming back in rice and flour bought from the supermarket?
- The most reliable method is to freeze all newly purchased dry goods — rice, flour, semolina, pasta, dried pulses — for four days before putting them into storage. This kills any eggs already present in the packet before they hatch. After freezing, transfer the contents to airtight glass or rigid plastic containers rather than keeping them in the original packaging. This single habit eliminates the main entry route for weevils into the home.
