What are Carpet Beetles?

Types of Carpet Beetles

Carpet beetles come in different shapes, sizes, and colors. Some are more common than others. In this section, we’ll explore the three most common types of carpet beetles:

Varied Carpet Beetle

The varied carpet beetle is the smallest of the three and measures around 1/8 inch long. It has a round body shape with a mix of black, brown, and white scales. The larvae are covered in long hairs and have a distinctive tuft of hair at the end of their body.

These beetles prefer to feed on natural fibers such as wool, silk, feathers, and fur. They can also infest dry pet food, spices, and dead insects.

Furniture Carpet Beetle

Furniture carpet beetles are slightly larger than the varied carpet beetle, measuring around 3/16 inch long. They have an oval-shaped body with a black, yellow, and white pattern of scales. The larvae are covered in short hairs and have a flattened body with a brown color.

These beetles prefer to feed on animal-based products such as leather, wool, fur, and feathers. They can also infest dried plant material, such as flowers and herbs.

Black Carpet Beetle

The black carpet beetle is the largest of the three and measures around 1/4 inch long. It has an elongated oval-shaped body with a shiny black color. The larvae are covered in short, stiff bristles and have a tapered body with a brown color.

These beetles prefer to feed on plant-based products such as cotton, linen, and rayon. They can also infest grains, cereals, and dried fruits.

While each type of carpet beetle has its own unique characteristics and preferences, they all share the potential to cause significant damage to your carpets, fabrics, and stored goods. Therefore, it’s crucial to identify and address any infestations promptly.

Where do Carpet Beetles Come From?

Carpet beetles are a common household pest that can be difficult to get rid of once they establish themselves in your home. Understanding where these pests come from is crucial in preventing an infestation from occurring in the first place.

One potential source of carpet beetles is through infested items, such as secondhand furniture or clothing. Adult carpet beetles may lay their eggs on these items, and when hatched, the larvae will begin to feed on the natural fibers of the materials. It’s important to thoroughly inspect any used items before bringing them into your home to avoid introducing these pests.

Stored food products can also attract carpet beetles, especially if they contain natural fibers or grains. Pantry items like flour and cereal should be kept in airtight containers to prevent infestations. Regularly cleaning out your pantry and checking for signs of pests can help catch an infestation early on.

Carpet beetles may also enter your home from outdoors, attracted by the scent of flowers or other plants. They can easily slip through small cracks and crevices in windows and doors, so sealing these openings can help prevent entry.

Lastly, pets can unknowingly bring carpet beetles into your home. They may pick up adult beetles or their larvae while outside and bring them inside on their fur. Regular grooming and vacuuming, especially in areas where pets spend time, can help prevent an infestation from starting.

By understanding the potential sources of carpet beetle infestations, you can take proactive measures to prevent them from entering your home in the first place.

Signs of a Carpet Beetle Infestation

How to Identify Carpet Beetles?

Carpet beetles are small pests that can cause significant damage to carpets, fabrics, and other household items. Identifying these insects is the first step in preventing and treating an infestation. Here are some key factors to consider when identifying carpet beetles:


Carpet beetles have a distinct appearance that can help you differentiate them from other pests. They have an oval-shaped body that is covered with tiny hairs or scales. These hairs give their body a fuzzy or speckled look. Carpet beetles also have six legs and two antennae on their head.


The size of carpet beetles varies depending on the species. On average, they range from 1/16 to 1/8 inch in length. The larvae are generally larger than the adults and can grow up to 1/4 inch in length.


The color of carpet beetles can vary widely depending on the species and life stage. Adult carpet beetles can be black, brown, or white. Their wings may have patterns or spots on them. Larvae, on the other hand, are usually light brown or yellow in color and have dark hairs or bristles.

It’s essential to identify the type of carpet beetle infesting your home accurately. Different species may require different treatment methods. If you’re unsure about what type of pest you’re dealing with, it’s best to contact a pest control professional for assistance.

Preventing a Carpet Beetle Infestation

Tips for Cleaning and Storing Fabrics

Tips for Cleaning and Storing Fabrics

Proper cleaning and storage of fabrics are essential to prevent carpet beetle infestations. Here are some tips that can help you keep your fabrics clean and free from pests:


  • Separate infested items: If you suspect an infestation, separate the infested items from the rest and wash them separately.
  • Wash in hot water: Use hot water (above 120°F) to kill the larvae and eggs of carpet beetles.
  • Dry thoroughly: After washing, dry the fabrics thoroughly using a dryer or hanging them outside in direct sunlight.
  • Add repellents: Add mothballs, essential oils, or cedar chips to the laundry to repel carpet beetles.


  • Use high heat: Dry your fabrics at high heat (above 120°F) to kill any remaining larvae or eggs.
  • Clean the dryer: Regularly clean your dryer to remove any accumulated lint, which can be a breeding ground for carpet beetles.


  • Iron thoroughly: Ironing your clothes can help kill any remaining beetles or their eggs hiding in the fabric fibers.


  • Use sealed containers: Store your fabrics in sealed containers, such as plastic bags or airtight containers, to prevent carpet beetles from accessing them.
  • Add repellents: Add mothballs, essential oils, or cedar chips to the containers to repel carpet beetles.

By following these tips, you can effectively clean and store your fabrics, preventing carpet beetle infestations and prolonging the life of your textiles.

Other Preventative Measures

Other Preventative Measures

Apart from cleaning and storage, there are other measures you can take to prevent carpet beetle infestations in your home. Here are some of the most effective:

Regular Vacuuming

One of the easiest ways to prevent carpet beetles is by regularly vacuuming your carpets, rugs, and upholstered furniture. This helps to remove any eggs, larvae, or adult beetles that may be hiding in the fibers.

Sealing Cracks

Sealing up cracks and gaps around doors, windows, and walls can help prevent carpet beetles from entering your home. This is particularly important if you live in an older home with lots of crevices where pests can hide.

Removing Infested Items

If you discover that an item in your home is infested with carpet beetles, it’s important to remove it immediately. This could include anything from clothing and linens to furniture and decorative objects. Be sure to dispose of infested items carefully, as they can spread the infestation to other parts of your home.

By implementing these preventative measures, you can significantly reduce the risk of a carpet beetle infestation in your home. However, if you do notice signs of an infestation, it’s important to act quickly to prevent the problem from getting worse.

Treating a Carpet Beetle Infestation

Using Insecticides Safely and Effectively

When it comes to dealing with a carpet beetle infestation, insecticides can be a powerful tool to eliminate these pests. But using insecticides incorrectly can be dangerous to both humans and pets, and may even exacerbate the problem.

The first step in using insecticides safely and effectively is to choose the right type of product for your needs. There are several types of insecticide products available on the market, including sprays, powders, foggers, and residual treatments. Each type has its own advantages and disadvantages, so it’s important to choose the one that will work best for your situation.

Sprays are a popular choice for carpet beetle control because they are easy to use and apply. They come in aerosol cans or pump spray bottles, and can be applied directly to infested areas. However, sprays may not penetrate deep into carpets or fabrics, and may not kill all stages of the carpet beetle life cycle.

Powders, on the other hand, are designed to penetrate deep into carpets and fabrics, making them ideal for eliminating hidden or hard-to-reach infestations. They contain active ingredients like boric acid or diatomaceous earth, which work by dehydrating and killing carpet beetles. However, powders can be messy and difficult to apply, and may need to be reapplied several times to be effective.

Foggers, also known as bug bombs, release a fine mist of insecticide into the air, killing carpet beetles on contact. Foggers are useful for treating large areas, but can be dangerous if used improperly. It’s important to follow the manufacturer’s instructions carefully, and to vacate the area for several hours after use.

Residual treatments, such as insecticide sprays or powders, are designed to provide long-lasting protection against carpet beetles. These products are applied to surfaces like baseboards or carpets, where they remain active for several weeks or months. However, residual treatments may contain harsh chemicals that can be harmful to humans or pets if ingested or inhaled.

No matter which type of insecticide you choose, it’s important to follow the instructions carefully and take all necessary precautions to protect yourself and your family. This may include wearing protective clothing and gloves, keeping children and pets away from treated areas, and properly ventilating the space after treatment.

In summary, while insecticides can be an effective way to eliminate carpet beetle infestations, it’s important to choose the right product for your needs and to use it safely and correctly. By following these tips, you can eradicate carpet beetles from your home and prevent future infestations.

Natural Remedies for Carpet Beetle Control

Natural remedies for carpet beetle control are a popular alternative to chemical-based solutions. These remedies offer a safe and eco-friendly way to get rid of carpet beetles without harming your family or pets. Here are some effective natural remedies that you can use to control a carpet beetle infestation:

Diatomaceous earth

Diatomaceous earth is a natural powder made from the fossilized remains of tiny aquatic organisms called diatoms. This powder works by dehydrating and drying out the exoskeletons of carpet beetles, causing them to die. To use diatomaceous earth, simply sprinkle it liberally on carpets, fabrics, and any other areas where carpet beetles are present.

Essential oils

Essential oils such as peppermint, lavender, and tea tree oil have natural insecticidal properties that can help repel carpet beetles. These oils can be used in several ways, including adding a few drops to a spray bottle filled with water, placing cotton balls soaked in essential oils in closets and drawers, or mixing them with carrier oils such as coconut oil and applying directly to carpets and fabrics.

Cedar oil

Cedar oil is another natural insect repellent that is effective against carpet beetles. This oil contains compounds that are toxic to carpet beetles, but safe for humans and pets. You can use cedar oil by spraying it directly on carpets, fabrics, and other infested areas, or by using cedar chips or blocks in closets and drawers.


Mothballs have long been used to repel moths, but they can also be effective against carpet beetles. These small white balls contain a strong-smelling chemical called naphthalene, which acts as a deterrent to carpet beetles. However, it’s important to note that mothballs should not be used in areas where children or pets may come into contact with them, as they can be toxic.

In conclusion, natural remedies such as diatomaceous earth, essential oils, cedar oil, and mothballs can be effective in controlling a carpet beetle infestation. However, it’s important to use these remedies correctly and safely, and to remember that they may not be as effective as chemical-based solutions in severe infestations.

When to Call Pest Control Professionals

If you’ve tried various DIY methods to get rid of carpet beetles, but the infestation continues to persist, it may be time to call in the professionals. Here are some situations where you should consider hiring pest control experts:
