Can Carpet Beetles Fly? Decoding the Myth for Homeowners

Carpet beetles are common household pests known for causing damage to fabrics, fur, and feathers.

While the adult beetles themselves do not damage fabrics, it is their larvae that wreak havoc on materials made from animal fibers.

Surprisingly, adult carpet beetles can fly and are often attracted to light sources such as windows.

The ability of carpet beetles to fly enables them to enter homes through various openings like vents, windows, doors, and eaves.

Once inside, these intruders can spread throughout a living space, laying eggs and causing damage as their larvae feed on fabrics and other materials.

Although it may seem like a small detail, understanding that carpet beetles can fly is an essential factor in managing their presence and preventing infestations in your home.

Effective control measures include sealing entry points, regular cleaning, and monitoring for signs of their presence.

Carpet Beetles Overview

Life Cycle of Carpet Beetles

Carpet beetles undergo a complete metamorphosis with four stages: eggs, larvae, pupae, and adults. Female carpet beetles lay around 100 eggs on various materials.

The larvae phase, which causes damage to fabrics and other materials, lasts for varying lengths of time depending on the species. For example, the black carpet beetle’s life cycle is 180 to 650 days.

Identifying Different Types

There are several common carpet beetle species:

• Black carpet beetle: Adults are 1/8 to 1/4 inch in length, black with brown legs, and carrot-shaped larvae.
• Varied carpet beetle: Adult beetles are small (3-5 millimeters or about an eighth of an inch), rounded, and have dark-colored or patterned wing covers. Larvae have alternating light and dark stripes with tiny hairs.
• Furniture carpet beetle: Similar to varied carpet beetle, but with different patterns on their wings.

Do Carpet Beetles Fly?

General Flying Abilities

Carpet beetles can indeed fly. The adult stage of these insects is capable of flight, while the larval stage cannot.

Adult carpet beetles typically feed outdoors on pollen, leaving the larvae to cause damage to fabrics and animal fibers¹.

Attraction to Lights

Adult carpet beetles are known to be attracted to lights and windows¹. This attraction can lead them to enter homes through open windows and doors.

Once inside, they can lay eggs and reproduce, resulting in infestations.

To minimize the risk of carpet beetles entering your home:

• Keep doors and windows closed or install screens
• Use yellow or sodium vapor bulbs for outdoor lighting, as they are less attractive to insects²

In summary, carpet beetles can fly, which makes it easier for them to enter homes and potentially cause damage.

Their attraction to lights and windows can lead them to infiltrate your living spaces, so taking preventative measures is essential.

Infestations and Damage

Materials Carpet Beetles Target

Carpet beetles are known to cause damage to a variety of materials, including:

• Wool: Clothing and rugs made of wool are common targets.
• Silk: Delicate silk fabrics are also at risk.
• Natural fibers: Other organic materials, such as cotton, can be affected.
• Animal products: Items made from feathers, fur, or leather are vulnerable.
• Furniture: Upholstered furniture containing natural fibers can be damaged.
• Food: Stored food products, such as grains, are susceptible to infestation.
• Dead insects/Plants: Beetle larvae feed on dead insects and even pollen from plants.

Recognizing the Signs

Physical evidence: Keep an eye out for small, round beetles with patterned wing covers. The larvae are most damaging and have a tapered body with alternating light and dark stripes.

Damaged items: Look for irregular holes or chew marks on affected materials.

The following table compares the signs of infestation and damage from carpet beetles to other fabric pests such as clothes moths:

Prevention and Control

Household Cleaning

One effective way to prevent carpet beetles is by maintaining cleanliness in your home.

Regular vacuuming, especially in areas where animal fibers or pet hair accumulate, can help remove carpet beetle larvae.

Steam cleaning can also be beneficial, as it kills larvae with high heat.

Another essential aspect of household cleaning is inspecting and sanitizing potential breeding sites, like closets or areas where you store fabrics.

Washing clothes and bedding regularly can also keep carpet beetles at bay.

Sealing Entry Points

Carpet beetles can enter your home through small gaps or cracks.

To prevent their entry, inspect your home for any openings and seal them with caulking or weather stripping.

This can be done around doors, windows, and other potential entry points.

If you are still having issues with carpet beetles you can call your local pest company.
