The Most Common Pantry Pests and How To Keep Them Out

Nothing hits the spot like a good meal. And nothing can make you lose your appetite quicker than spotting a bug where you were about to take a bite.

While flies and bees might crash your outdoor picnic, some pests prefer a more discreet dining spot — your pantry.

Whether it’s a trail of ants in your sugar or pantry moths fluttering around your flour, stored food pests are an unappetizing surprise. These insects invade food storage, contaminate dry goods, and leave you with a mess to clean up that goes beyond doing the dishes. But by following a few steps, you can keep these extra cooks out of the kitchen for good.

Common Pantry Pests and How They Get In

Flour Beetles

Known for thriving in stored grains like flour, cereal, and even spices, flour beetles are a small, reddish-brown insect. They often enter your home through infested food products from the store or a farmer’s market. Once inside, flour beetles can spread quickly, growing from an egg to a full-sized adult in just a few weeks. They contaminate any food they come in contact with, so products should be discarded — no matter how magically delicious they are.

Pantry Moths

If you notice things fluttering around when you turn on your pantry lights, you might be dealing with pantry moths. Also known as Indianmeal moths or flour moths, these winged pests lay eggs in dry foods like grains, nuts, and pet food. Once hatched, the larvae spin silk webbing in your food, ruining entire packages of stored goods.

Ants

It turns out that these picnic pests are more than happy to extend themselves an invitation indoors. As expert foragers, ants can sniff out a pantry, and if they find yours, they’ll keep coming back for more. They’re especially drawn to sweet, sticky, and greasy foods, making sugar, honey, and cereals prime targets.

Weevils

Did you spot a bug that looks like a cross between a beetle and an elephant? You’re likely dealing with weevils. These sneaky beetles are notorious for infesting rice, grains, and dried beans. Weevils often start their lifecycle inside the food itself, hatching from eggs that were already in the grains before you even brought them home. By the time you notice these long-nosed pests, you likely have a full-blown infestation.

How to Prevent Pantry Pests

Finding pantry pests is frustrating, but preventing them in the first place is much easier than dealing with an infestation. By taking a few extra steps, you can keep these unwanted guests from making themselves at home.

1. Inspect Food Before Buying
Pantry pests often hitch a ride in food packaging from the store. Check for holes, tears, or signs of insect activity before bringing items home. If you notice clumped grains, webbing, or small moving dots, choose another product.

2. Store Food in Airtight Containers
Cardboard and paper packaging aren’t enough to keep pests out. Transfer dry goods like flour, rice, and pasta into airtight containers made of glass or plastic to prevent infestation.

3. Keep Your Pantry Clean
Crumbs and spills attract pests. Regularly wipe down shelves, vacuum corners, and check for forgotten open packages. Clean up any spills immediately, especially sweet or greasy substances.

4. Rotate Your Food Stock
Use older products first and avoid storing food for long periods. “First in, first out” is a good way to ensure nothing sits long enough to attract pests.

5. Seal Entry Points
Ants and other insects can squeeze through tiny cracks and crevices. Seal gaps around doors, windows, and pantry shelves to reduce entry points.

How to Get Rid of Pantry Pests

If you already have an infestation, acting fast is a must. First, discard any food that’s been infested. Help prevent the insects from spreading by putting the infested food in a sealed bag before you throw it out.

Once you’re sure that all contaminated food is gone, the next step is to clean your pantry. Vacuum your shelves to pick up any leftover eggs, larvae, or insects and wipe down all surfaces with warm, soapy water or a vinegar solution.

After everything is clean, you can place a few natural deterrents and traps in your pantry to make sure the invaders don’t come back. Depending on your pest, bay leaves and cedar blocks can help repel them from food storage areas. There are also types of pheromone traps that work best on pantry moths and ants to keep them off the food scent.
