Confused flour beetles are a nuisance when it comes to stored foods and grains. They are known to infest areas where they have access to these stored goods. Confused flour beetles are often misidentified and have a striking resemblance to red flour beetles, and these two species can usually be found infesting the same areas.

When in your home, confused flour beetles will infest your pantry in search of stored foods. After they gain access to your home and food, they will multiply and contaminate your food stores in the process. Learning how to store dry foods and grains properly will help to prevent confused flour beetles from invading your pantry.

What Is a Confused Flour Beetle?

Confused flour beetles are one of the most common pests to infest stored food products. They feed on the dust and broken bits of flour, grains, pasta, and cereal. They usually originate in warehouses where these types of products are produced. The supply chain then introduces confused flour beetles into grocery stores, and they make their way into your home inside the packaging of these stored goods.

Once confused flour beetles have made their way into your pantry, they can quickly move to other foods. If left unchecked, they can ruin all of your stored goods by making them unfit for consumption. Farms and warehouses can suffer catastrophic losses due to the destruction that these pests can dish out during an invasion. When the damage they cause is severe enough, it can cause economic hardship for the farmers and businesses involved.

The extent of foods that confused flour beetles will eat isn’t confined to just flour and grain. They have been known to eat spices, beans, dried flowers, nuts, chocolate, dried pet food, dried museum specimens, and seeds; this makes them a threat to many different industries, and they can be hard to control after they have established themselves in an area. If you think that you might have a confused flour beetle infestation in your pantry, knowing how to identify them will help you determine the best course of action to take to remedy the situation.

What Do Confused Flour Beetles Look Like?

Confused flour beetles are a reddish-brown color and range from 3 millimeters to 6 millimeters in length. They have an elongated and flat body with a head, six legs, and antennae. They also have wings that are covered by a protective shell.

Confused flour beetles have earned the “confused” in their name by being commonly confused with red flour beetles. These two separate species are so similar that distinguishing between the two may require a microscope. The main difference that distinguishes the confused flour beetle from the red flour beetle is their antennae. The confused flour beetle’s antennae have four clubs and gradually increase in size. The red flour beetle’s antennae only have three clubs.

Where Do Confused Flour Beetles Live?

Confused flour beetles originate from Africa, yet they are found worldwide in colder climates. The northern United States is home to these destructive pests. They are naturally occurring where grains are grown, but they will quickly move into the silos and warehouses the grains are stored in and begin to breed in these well-protected places.

Females are capable of laying up to 450 eggs and will lay them in loose food materials or broken kernels. The eggs will then hatch in 12 days or less, and the young begin to feed immediately. After about four months, they will have developed into adults and have an average life span of a year, but they have been known to live up to three years.

Problems With Confused Flour Beetles

Confused flour beetles can cause significant damage to grain crops, food stores, and other types of dried goods. When they have infested farms and businesses, they can cause the losses of entire harvests and disrupt the production of foods that contain grain. Once they have established themselves within the supply chain, they can be unknowingly transported to grocery stores, restaurants, and your home.

After Confused flour beetles have gained access into your home and pantry, they can contaminate and destroy all of your food stores; which can be financially distressing, since you will have to restock any spoiled food.
