How to Know if You Have Carpet Beetles

How to Know if You Have Carpet Beetles| Full Scope Pest Control

Carpet beetles, though tiny, are a significant threat to your home furnishings. These pests are notorious for loving natural fibers and can cause considerable damage if they go unnoticed. However, identifying the signs of carpet beetles in your house may be harder than finding an errant ant or spider.

In this blog, we will discuss identifying if you have carpet beetles in your home. Let’s delve into the various indicators that can help you determine if carpet beetles have invaded your living space.

What Are Carpet Beetles?

Carpet beetles belong to the Dermestidae family, which includes over 2000 species worldwide. The variegated carpet beetle, furniture carpet beetle, and black carpet beetle are the most frequent types. As their names suggest, these beetles often dwell in carpets, rugs, and upholstered furniture. They are drawn to natural fibers, particularly wool, silk, fur, and feathers.

Carpet beetle larvae are the primary culprits when it comes to damage. They consume natural fibers and can leave behind a visible trail of destruction, including irregular holes in fabrics, while the adults are more interested in pollens and flower nectar.

Identifying Carpet Beetles

Knowing what carpet beetles and their larvae look like is crucial in identifying them.

Adult Carpet Beetles

Adult carpet beetles are small and round, measuring about 2-4mm long. Their coloration varies, depending on the species. For instance, varied carpet beetles are black with an irregular pattern of white, brown, and yellow scales on their back. In contrast, furniture carpet beetles are more uniformly colored, typically black or dark brown.

Carpet Beetle Larvae

The larvae are elongated and hairy. They are larger than the adults, reaching up to 5 mm in length. They are often carrot-shaped and brown or tan in color with dark heads.

Understanding the Life Cycle of Carpet Beetles

Understanding the life cycle of carpet beetles can help you better manage potential infestations. Carpet beetles undergo complete metamorphosis, passing through four stages: egg, larva, pupa, and adult.

The Egg Stage

Carpet beetles lay their eggs in dark, undisturbed areas often associated with a food source for the larvae. Depending on the conditions, a clutch of 100 eggs can hatch from a single female in anywhere from 10 to 20 days.

The Larval Stage

This is the most destructive stage. Depending on their environment, larvae feed on natural fibers and can continue for several months to even years.

The Pupal Stage

Once the larva is fully grown, it enters the pupal stage. This stage lasts 10-14 days, after which the adult beetle emerges.

The Adult Stage

Adult carpet beetles feed on plant-based foods, including pollen and nectar. They live between two weeks to a few months and seek light sources, explaining their presence near windows.

Signs of Carpet Beetle Infestation

Identifying a carpet beetle infestation relies on several key signs.

Fabric Damage

The most prominent sign of a carpet beetle infestation is damage to natural fiber items. You may notice irregular holes in your carpets, clothing, upholstered furniture, woolen blankets, or feather pillows.

Shed Larvae Skins and Fecal Pellets

As carpet beetle larvae grow, they molt and leave behind their shed skins. These skins look like tiny, hairy caterpillars and are often found near the infested items. The larvae also leave fecal pellets, which are small, round, and the same color as the infested fabric.

Sightings of Adult Beetles

While the adults do little damage, spotting them inside your home is a telltale of an infestation. As a result, they are often noticed near windows or other sources of artificial light.

How to Deal with Carpet Beetle Infestations

If you’ve identified a carpet beetle infestation in your home, immediate action is necessary to prevent further damage.


Carpet bugs can be eliminated with routine and thorough cleaning. Vacuuming can help remove larvae, adults, and eggs from carpets, rugs, and furniture.

Professional Pest Control

If the infestation is large or widespread, consider seeking professional help. Carpet beetle infestations require the knowledge and equipment of pest control services.

Prevention is Better Than Cure

The best defense against carpet beetles is proactive prevention.

Regular Cleaning

Regular cleaning of your home can go a long way in preventing a carpet beetle infestation. Vacuum your carpets, rugs, and furniture regularly, paying particular attention to hidden and hard-to-reach areas where beetles might lay eggs.

Proper Storage

Carpet beetles are drawn to natural fibers, so carefully preserving such goods when not in use is critical. This includes clothing, blankets, and other fabric items. Ensure they are clean before storing them in air-tight containers or garment bags.

Inspect Second-hand Items

If you purchase second-hand furniture or clothing, inspect them carefully before bringing them into your home. These items can sometimes harbor carpet beetles or their eggs.



Understanding carpet beetles, their signs, and the potential damage they can cause is the first step toward protecting your home. Prevention through regular cleaning, proper storage of susceptible items, and early detection is key in controlling these pests. Despite their small size, their potential problems make carpet beetles a threat to be taken seriously.

Remember, if the infestation is beyond your control, seeking professional pest control services is always an option. The sooner an infestation is addressed, the less damage these pests will cause. So, watch for carpet beetles and take swift action if you find them sharing your space!
