When it comes to household pests, most people think of ants, spiders, or rodents. But lurking in your pantry—right under your nose—could be an even sneakier intruder: the weevil! These little grain-loving pests can turn your stored food into an all-you-can-eat buffet, and before you know it, your flour, rice, or even your spices could be crawling with unwanted guests.
At Sasquatch Pest Control, we know that battling weevils isn’t just about eliminating them—it’s about keeping them out in the first place. Let’s break down what these pantry invaders are and how you can protect your home from an infestation.
Meet the Weevils: Rice & Granary Weevils
Two of the most common types of weevils found in stored food are the Rice Weevil and the Granary Weevil.
Rice Weevil (Sitophilus oryzae)
🔹 About 1/8″ long, reddish-brown with faint yellowish spots
🔹 Distinct snout with chewing mouthparts
🔹 Can fly and is attracted to light
🔹 Targets corn, wheat, rice, beans, nuts, cereals, and even fruit like apples and pears
Granary Weevil (Sitophilus granarius)
🔹 Slightly larger at 1/8″–1/4″ long
🔹 Dark reddish-brown to black, without spots
🔹 Cannot fly and is not attracted to light
🔹 Infests a variety of stored grains and grain products
Both of these pests have larvae that are small, legless, and white with a dark head. They burrow into food, making them hard to spot until it’s too late!
How to Spot an Infestation
The first sign of a weevil invasion usually isn’t a big neon sign saying “Hey, your food is infested!” Instead, you might notice:
✅ Small beetles crawling in your pantry or food containers
✅ Fine, sawdust-like droppings (called frass)
✅ Webbing inside food packaging
✅ Worm-like larvae in cereals, flour, or spices
If you see any of these signs, it’s time to act fast before the problem spreads!
Weevil Control & Prevention
1. Store Food Properly
Weevils are like tiny burglars—if they can’t get in, they can’t steal your food! Always store dry goods in airtight glass, plastic, or metal containers with tight-fitting lids.
2. Keep It Cool & Dry
Heat and humidity help weevils thrive. Keeping your pantry cool and dry slows their reproduction. If you have bulk grains, flours, or nuts, consider storing them in the freezer for added protection.
3. Inspect & Rotate Food
Before bringing dry goods home from the store, inspect them for damage. Once home, use older items first to prevent anything from sitting too long and attracting pests.
4. Clean Your Pantry
If you find weevils, remove all infested food and vacuum the shelves thoroughly—especially in the corners where eggs or larvae might be hiding. Wipe everything down with warm, soapy water and avoid using insecticides where food is stored.
