Larder beetles, also known as Dermestes lardarius, are a common household pest that can cause significant damage to food, carpets, and other household items. These small, oval-shaped insects are usually brown or black in color and have a distinctive six-spotted pattern on their backs. If you’re finding larder beetles in your home, it’s essential to understand why they’re there and how to get rid of them.
What Attracts Larder Beetles to Your Home?
Larder beetles are attracted to food sources, particularly high-protein foods like meat, dairy products, and pet food. They can also infest grains, cereals, and other starchy foods. In addition to food, larder beetles are drawn to moisture, warmth, and darkness, making your home an ideal environment for them to thrive.
Common Food Sources for Larder Beetles
Some common food sources that may attract larder beetles to your home include:
-
- Pet food: Larder beetles can infest dog food, cat food, and other pet food, especially if it’s stored in a warm, humid environment.
- Meat: Larder beetles can infest raw or cooked meat, including beef, pork, and poultry.
- Dairy products: Larder beetles can infest cheese, milk, and other dairy products.
- Grains: Larder beetles can infest grains like rice, wheat, and oats.
- Cereals: Larder beetles can infest breakfast cereals, especially if they’re stored in a warm, humid environment.
Other Factors That Attract Larder Beetles
In addition to food, other factors that may attract larder beetles to your home include:
-
- Moisture: Larder beetles need moisture to survive, so they’re often found in humid environments.
- Warmth: Larder beetles thrive in warm temperatures, typically between 65°F and 90°F (18°C and 32°C).
- Darkness: Larder beetles prefer dark environments, which is why they’re often found in pantries, cupboards, and other enclosed spaces.
How Do Larder Beetles Get into Your Home?
Larder beetles can get into your home through various means, including:
Used Furniture and Appliances
Larder beetles can hide in used furniture and appliances, especially if they’re infested with food debris or other organic matter. When you bring these items into your home, you may unintentionally introduce larder beetles into your environment.
Food and Packages
Larder beetles can also hide in food packages, especially if they’re not properly sealed or stored. When you bring infested food into your home, you may introduce larder beetles into your environment.
Cracks and Crevices
Larder beetles can enter your home through cracks and crevices, especially around windows, doors, and vents. They can also enter through holes in screens or vents.
Signs of a Larder Beetle Infestation
If you suspect that you have a larder beetle infestation, look for the following signs:
Live Beetles
The most obvious sign of a larder beetle infestation is the presence of live beetles. They’re usually found near food sources or in dark, humid environments.
Shed Skins
Larder beetles shed their skins as they grow, leaving behind a trail of discarded skins. These skins are usually found near food sources or in areas where the beetles are present.
Holes in Food Packages
Larder beetles can chew holes in food packages, especially if they’re made of paper or cardboard.
Frass
Larder beetles produce frass, a type of insect waste that resembles sawdust or coffee grounds. Frass is usually found near food sources or in areas where the beetles are present.

What are larder beetles and how do they look?
Larder beetles are small, oval-shaped insects that belong to the family Dermestidae. They are typically 1/4 inch long and have a shiny black body with a distinctive red or yellow band running across their back. The larvae of larder beetles are legless, grub-like creatures that are usually white or cream-colored.
Adult larder beetles have six legs and two antennae, and they are able to fly. They are often mistaken for carpet beetles, but larder beetles have a more elongated body shape and a distinctive pattern of hairs on their body. Larder beetles are also known for their ability to infest a wide range of food sources, including grains, dried fruits, and even leather.
What do larder beetles eat and how do they infest homes?
Larder beetles are opportunistic feeders that can infest a wide range of food sources. They are particularly attracted to high-protein foods such as meat, dairy products, and pet food. They can also infest grains, dried fruits, and other stored food products. In addition to food, larder beetles can also infest non-food items such as leather, wool, and silk.
Larder beetles typically infest homes through contaminated food products or on used furniture and appliances. They can also enter homes through open windows, doors, and vents. Once inside, they can quickly spread to other areas of the home, infesting a wide range of food sources and non-food items. Larder beetles are also known to hide in small, dark areas such as behind baseboards and in wall voids.
What are the signs of a larder beetle infestation?
The signs of a larder beetle infestation can vary depending on the severity of the infestation and the type of food or non-food item being infested. Common signs of a larder beetle infestation include the presence of live beetles or larvae, as well as small, round holes in food packaging or other materials. Larder beetles can also leave behind a trail of tiny, white eggs or a fine, powdery residue.
In addition to these physical signs, larder beetles can also cause a range of other problems, including unpleasant odors and flavors in infested food products. They can also cause damage to non-food items such as leather, wool, and silk. In severe cases, a larder beetle infestation can lead to significant financial losses and even health problems.
How can I prevent larder beetles from infesting my home?
Preventing larder beetles from infesting your home requires a combination of good housekeeping practices and smart food storage habits. One of the most effective ways to prevent larder beetles is to store food in airtight containers and to keep your home clean and free of clutter. Regularly vacuuming and dusting can also help to reduce the risk of a larder beetle infestation.
In addition to these general precautions, it’s also a good idea to inspect any used furniture or appliances before bringing them into your home.

By taking these simple steps, you can significantly reduce the risk of a larder beetle infestation.
How can I get rid of larder beetles in my home?
Getting rid of larder beetles in your home requires a combination of non-chemical and chemical methods. One of the most effective ways to get rid of larder beetles is to thoroughly clean and declutter your home, paying particular attention to areas where food is stored. You should also dispose of any infested food products or non-food items.
In addition to these non-chemical methods, you may also need to use insecticides to get rid of larder beetles. There are a range of insecticides available that are specifically labeled for use against larder beetles, including sprays, powders, and baits. It’s generally best to use a combination of these methods, and to repeat treatments as necessary to ensure that all of the larder beetles are eliminated.
Can larder beetles cause health problems?
Larder beetles are not typically considered to be a significant health risk, but they can cause a range of problems in certain individuals. For example, some people may be allergic to the hairs or body parts of larder beetles, which can cause skin irritation or respiratory problems. Larder beetles can also contaminate food products, which can lead to food poisoning or other health problems.
In addition to these direct health risks, larder beetles can also cause indirect health problems by infesting food products that are high in fat or protein. For example, larder beetles can infest pet food, which can lead to malnutrition or other health problems in pets. They can also infest food products that are intended for human consumption, which can lead to a range of health problems.
How can I tell if I have a severe larder beetle infestation?
A severe larder beetle infestation can be identified by a range of signs, including a large number of live beetles or larvae, as well as significant damage to food products or non-food items. In severe cases, a larder beetle infestation can also cause unpleasant odors or flavors in infested food products, as well as a fine, powdery residue.
If you suspect that you have a severe larder beetle infestation, it’s generally best to seek the advice of a pest control professional. They can assess the severity of the infestation and recommend the best course of treatment. In some cases, a severe larder beetle infestation may require repeated treatments or specialized equipment to eliminate the infestation.
