10 Tips To Help Protect Your Home From Pantry Pests

Pantry pests is a most unimaginative moniker for insects that like to hang out in your pantry.

Also known by the equally humdrum name, Stored Product Pests, these critters have an insatiable appetite for the dried and processed food products that are stored in your home. 

They can include: flour; cereal; powdered milk; pasta; dry pet food; cornstarch; crackers; spices; bread; bird seed; dried nuts; fruit and more.

Pantry pests can breed almost continuously, as they tend to live inside the food products they thrive on.

They can produce several generations over the course of a single year.

Some Common Pantry Pests Found In Homes 

Pantry pests include a variety of insects, the most common of which are: the Indian Meal Moth, the Saw-Toothed Drain Beetle, the Flour Beetle, weevils and the Cigarette Beetle are most commonly found in kitchens and homes.

The following paragraphs detail these various types of pantry pests.

What is an Indian Meal Moth?

In an odd twist of fate, Indian meal moths are probably the most common pests the average homeowner doesn’t know by name.

Also known as weevil moth, pantry moth, flour moth or grain moth, according to Penn State University’s Department of Entomology: “The Indian meal moth is one of the most commonly reported pests of stored grains in the United States.

Even when compared to other household pests and other types of moths, this critter is unstoppable once it considers your pantry its very own “home sweet home.”

Common pantry foods are far more vulnerable than might otherwise be expected because the larvae of the Indian Meal Moth can easily eat through plastic and cardboard.

Sealing stored food in plastic bags and boxes is really not much protection against these voracious pests.

They are cosmopolitan critters that prefer tropical climates but they are found all over the world except Antarctica.

This moth is by far, the most common and destructive stored food pest found in the United States today.

Indian Meal Moth Control

They do all their damage during their larval stages because it is at this stage in development that they eat every second they are alive.

These moths lay eggs on or near food to insure the larvae will have something to eat the moment they hatch.

These critters can easily eat through cardboard and soft plastic.

Only airtight hard plastic containers can keep these stored food pests from infesting stored grains.

Home owners should watch out for crumbs accumulating in a pantry, as they can attract pantry pests.

Indian meal moths are also more mobile than other pest invaders.

This translates into the most disturbing realization that just because you once saw them around your pantry and now you don’t doesn’t mean you no longer have an infestation.

As a homeowner, you still need help with pest-management and pest-control strategies, such as those Pestco can offer.

But even the experts do not have an easy road ahead of them, as Indian meal moths have developed biological resistances to various pest-control measures.

In their own horrible way, Indian meal moths have actually out-evolved modern science!

There are a variety of beetles that can make their way into a residence and pantry, but the most common are saw-tooth grain beetles, flour and confused flour beetles, cigarette beetles and various types of weevils.

Further information is listed below.

The Red Flour Beetle and The Confused Flour Beetle

Even though they are two entirely different species, they are so similar that the confused flour beetle was so named because it is often “confused” with its red flour cousin.

Without the aid of a magnifying glass, it is difficult to tell the two apart.

The Red Flour Beetle is of Australian origin, and is found worldwide in warm climates, but it can survive the winter months in homes where central heating provides protection from the cold.

The Confused Flour Beetle originated in Africa and its distribution occurs mostly in colder climes. Both species attack stored grain products in homes and grocery stores.

These include: flour; cereals; crackers; beans; spices; pasta; cake mix; dried pet food; dried flowers; chocolate; nuts; seeds and even dried museum specimens.

The Saw-Toothed Grain Beetle

These pantry pests are known to attack almost any dry food under the sun, but they are most likely to be found in cereal products such as flour; cake mix; cornmeal; macaroni and other pantry products such as bread; dried fruits; nuts; chocolate and dry pet food.

Like other species of pantry pests, it is the larvae that cause the damage and contamination of food stuffs.

It is the adult insect, however, that is most encountered by humans, as they are known to to gain ingress via sealed (and broken) cardboard boxes and soft plastic packages.

The Cigarette Beetle

The cigarette beetle is known all over the modern world and is found especially wherever dried tobacco in the form of leaves, cigars, cigarettes, or chewing tobacco is stored.

These pests have caused severe economic losses to many businesses including: flour mills; bakeries; pet food factories; cereal manufacturing centers; snack food plants; chocolate factories; confectionaries; wholesale distribution centers; and sometimes retail stores.

Cigarette Beetle Pantry Pest Control

In addition to being the most damaging pest of stored tobacco, the cigarette beetle is a major invader and destroyer of many stored food products kept in kitchen cabinets, pantries and other areas in the average home.

These include: flours; dry mixes; dried fruits like dates and raisins; cereals; coffee beans; herbs; spices; nuts; rice and dry pet food.

These insect invaders evoke disgust and anger to all who find them ruining products purchased with hard-earned money.

Just when homeowners might think that other items in their home might be safe, they discover that these destructive pests infest non-food products as well.

Some of these include: dried floral arrangements; potpourri; decorative grapevine wreaths; prescription drugs and pills; medicinal herbs; furniture stuffing; papier-mâché items and bookbinding paste.

Our integrated pest management (IPM) solutions are often implemented to control these infestations for homes throughout Pittsburgh.


These small reddish brown beetles known for their elongated snouts, are often found in kitchen cupboards and pantries.

Unlike beetles that live and feed on foods, weevils live and feed inside the food.

In an average residence, weevils can be brought in on packaged products or they can enter from outside.

Once inside, they multiply rapidly and can quickly destroy stored food items if they are not controlled by pest specialists.

The major problem is finding the source of the infestation because these insects naturally blend in with their environment, making them difficult to identify.

Preventing their ingress into your home us the best way to deal with these stored product pests. Consider the following helpful tips listed below.

1) Store Dry Food In Air-Tight Containers

One way to minimize the risk of pantry pest infestations is to ensure that all food products are stored in air-tight containers and that your pantry or cupboards are kept clean and free of food that may be left open or not closed properly.

This prevents any existing pests from contaminating newer products.

Remove dry pantry foods and bulk foods from original containers and store them instead in tight-fitting containers.

Also, don’t forget to clean old containers before filling them with fresh food.

2) Do Not Store Old And New Products Together

Never combine older and new dry food products unless you’re absolutely sure both products are pest-free.

This is because if the older food materials are infested, the newer ones will soon be.

3) Avoid Buying Damaged Food Boxes of Any Kind

When food shopping, do not purchase boxes that already look damaged and inspect all bags/boxes prior to purchasing to ensure that they are securely sealed.

In addition, be wary when purchasing specialty items such as international foods, holiday specialty items, i.e. matzah meal, corn meal etc.

These types of products often sit on store shelves longer than staple food items and are highly susceptible to grain pest infestation.

4) Always Check Expiration Dates On Food In Your Pantry

Periodic checks on food in the pantry will help to organize older items that might have lost their way to the dining room table.

Dispose of any food that is past its expiration date and/or has been stored for a long period of time.

5) Add Bay Leaves To Canisters And Packages In Your Pantry

This herb deters pantry pests in general because its aroma is pungent and distasteful to most stored food pests.

Place whole bay leaves on counter tops, under cabinets and appliances, around trash cans and along baseboards.

6) Be Careful When Buying Bulk Food Items 

Grains, spices, rice, dry pet foods, birdseed, bird suet and other products often sold in bulk are particularly vulnerable to pantry pest infestations.

Beware of moths or beetles seen on shelves or flying in the air when walking down store aisles.

These are true indicators of an infestation.

7) Clean Pantry Shelves Regularly

Removing the small bits of food that pantry pests thrive on helps to eliminate their food source.

As an extra safety measure, wash the shelves, walls, and corners thoroughly before returning any items to the pantry.

8) Keep Food Storage Units Dry At All Times

This is very important because moisture attracts pantry pests.

Homeowners should  keep food storage areas dry via a fan or dehumidifier.

9) Pesticides Are Not Recommended For Pantry Pest Control
