Carpet Beetles

How to Get Rid of Carpet Beetles in Your Home

Carpet beetles are small household pests whose larvae can damage certain fabrics and other materials containing natural animal fibers. Finding an occasional adult beetle does not always mean you have an infestation, but discovering larvae, shed skins, or damaged belongings deserves further investigation.

Successful carpet beetle control begins with locating and removing the material on which the larvae are feeding.

What Do Carpet Beetles Look Like?

Several carpet beetle species are commonly found in California, including varied, furniture, and black carpet beetles.

Adult carpet beetles are small and usually measure about 1/8 inch long. Depending on the species, they may be black or have a mottled pattern of white, brown, and yellow scales. Adults can fly and are often discovered near windows because they are attracted to light.

Carpet beetle larvae are elongated, brownish, and covered with visible hairs or bristles. You may also find their empty, shed skins in closets, drawers, along baseboards, or underneath furniture.

What Causes the Damage?

Adult carpet beetles mainly feed outdoors on pollen and do not damage fabrics. The larvae cause the damage.

Carpet beetle larvae may feed on:

• Wool and wool-blend fabrics
• Silk
• Fur, feathers, and leather
• Natural-bristle brushes
• Pet hair and human hair
• Lint and accumulated debris
• Dead insects
• Animal-based materials in stored foods
• Dead rodents or abandoned bird nests

Synthetic carpeting and clothing generally are not suitable food unless they contain natural fibers or are contaminated with perspiration, food, oils, hair, or other organic material.

Signs of a Carpet Beetle Infestation

Common signs include:

• Small adult beetles near windows
• Hairy larvae crawling along walls or floors
• Shed larval skins in undisturbed areas
• Irregular holes in clothing or natural-fiber fabrics
• Damage along the edges or underside of rugs
• Bare areas on wool carpeting
• Activity in closets, storage containers, or upholstered furniture

Carpet beetle damage may be confused with clothes moth damage. Saving a specimen can help confirm which pest is present.

Find the Source of the Infestation

Inspect the areas where larvae, shed skins, or damaged items have been found. Pay close attention to:

• Carpet edges and areas underneath furniture
• Closets containing wool, silk, leather, or fur
• Stored blankets and clothing
• Upholstered furniture
• Heating vents and floor registers
• Attics, garages, and storage rooms
• Collections of lint or pet hair
• Bird or rodent nesting materials
• Dead insects in window tracks, wall voids, or light fixtures

Finding and removing the source is usually more effective than simply spraying the visible insects.

Clean the Affected Areas Thoroughly

Vacuum rugs, carpet edges, baseboards, closets, upholstered furniture, and areas beneath heavy furniture. Pay particular attention to cracks and undisturbed spaces where lint, hair, and dead insects collect.

Dispose of the vacuum bag or empty the canister outdoors immediately after cleaning because it may contain carpet beetle eggs, larvae, or adults. Repeat vacuuming may be needed.

Wash or dry-clean affected clothing and fabrics according to the manufacturer’s instructions. Items do not necessarily need to be discarded if they can be cleaned successfully and are not badly damaged.

Protect Clothing and Stored Items

Before placing fabrics into storage:

• Make sure they are clean and completely dry.
• Inspect them for larvae, shed skins, and damage.
• Store susceptible items in sealed containers or garment bags.
• Periodically inspect stored woolens, blankets, and similar belongings.
• Avoid leaving natural-fiber materials undisturbed for long periods.

Cleaning is important because carpet beetle larvae can be attracted to perspiration, food stains, body oils, and other residues.

How Do Carpet Beetles Enter a Home?

Adult carpet beetles normally live outdoors and feed on pollen. They can enter through open doors, windows, vents, and damaged screens. They may also be brought indoors on cut flowers or infested belongings.

Repair damaged screens and seal unnecessary openings around doors, windows, and utility penetrations. Inspect cut flowers before bringing them inside.

Are Carpet Beetles Harmful to People?

Carpet beetles do not bite or feed on people. However, the tiny hairs shed by their larvae can irritate the skin of some individuals and may be mistaken for insect bites.

Removing the insects, shed skins, and infested material generally resolves the problem.

Is Professional Treatment Necessary?

Many carpet beetle problems can be corrected by finding the source, thoroughly cleaning affected areas, and protecting susceptible materials. Pesticide treatment alone will not solve the problem if the larvae’s food source remains.

Professional assistance may be appropriate when:

• Larvae continue appearing after thorough cleaning.
• The source cannot be located.
• Activity is coming from an attic or inaccessible area.
• Valuable rugs, furnishings, or stored items are threatened.
• The insects have not been positively identified.
