Carpet beetle eggs are the main source of infestation of carpet beetles in homes. The female carpet beetle will deposit her eggs on protected surfaces near food sources. She will typically lay between 40 and 100 eggs in the same area, depending on the size of the clutch.

The eggs are small and white, and they will hatch within a week or two. They are difficult to see on most surfaces. The article goes on to list ways to identify them as well as avoid conditions that could lead to an infestation.

The Habitat of Carpet Beetles

Carpet Beetle Eggs

Carpet beetles can be found throughout the United States in various habitats. They are commonly found in homes, feeding on carpets, furniture, and other textiles. However, they can also be found in outdoor environments, such as gardens and fields.

Carpet beetles are found in many different habitats all over the world. They inhabit most of Europe and the Near East, including Northern Asia, Northern Africa, and Central and South America through the latter’s temperate zones.

Carpet beetles, namely the black carpet beetle and the varied carpet beetle, are the ones that are most likely to cause damage inside your home. They feed on natural fibers such as wool, silk, and cotton.

If you see an adult carpet beetle or its eggs around your home, it’s important to take action immediately.

What do carpet beetle eggs look like?

Carpet beetle eggs are small, oval-shaped, and have spine projections. They are creamy-white and can be difficult to see on light-colored surfaces. The corridors in the eggs are what give them their backbone-like appearance. These corridors allow the larvae to move around and eat.

Carpet Beetle Eggs

Carpet beetle eggs are a common sight in households. The eggs hatch into larvae, which go through molts before pupating and emerge as adults. From egg to adult, the entire process takes about a year, anywhere from six to eight weeks.

If you see small, white eggs around your home, there’s a good chance they are carpet beetle eggs. Carpet beetle eggs range in size from 1/4 to 1/2 inch in length and are cream or white.

They have spinelike projections visible at one end and are oval-shaped. You can find them near upholstered furniture, closets, air ducts, and lint buildups.

The eggs of the adult carpet beetle are deposited in batches and generally hatch within a week. The larvae will feed on natural fibers for up to two years, pupate, and then emerge as adults.

When do carpet beetles lay eggs?

Carpet beetle eggs are typically laid in the springtime when the weather starts to warm up. This is because the larvae need certain conditions to grow and develop properly, and laying their eggs in these places helps them do so.

Each female lays three batches of eggs, each comprising 20 to 100 eggs. Carpet beetle eggs are often found in areas where the larvae can find food. The mother will typically deposit them in a secluded area where they will be safe from potential predators.

Where do carpet beetles lay eggs?

Carpet beetles lay eggs in dark and quiet places where the conditions are optimal for their development. Typically, carpet beetles choose to lay their eggs under carpets and other surfaces where they can be protected.

The larvae will hatch and feed on the organic matter in those areas, including hair, fur, skin cells, and dried blood. The eggs will hatch into larvae, feeding on whatever they can find to grow.

How Many Eggs Do Carpet Beetles Lay?

Carpet beetles lay an average of 90 eggs at a time. The eggs are small, white, and oval-shaped. They hatch in about ten days, and the larvae will feed on various materials, including carpets, furniture, clothing, and other textiles.

Interestingly, carpet beetle eggs hatch in 177 to 370 days. After hatching, the larvae feed on various materials, including carpets, furniture, and clothes. If you’re seeing an increase in these beetles in your home, it’s important to identify and remove their eggs as soon as possible.

The life span of a carpet beetle larva is much longer than the adult life span. Carpet beetle eggs hatch into larvae, which can live up to two years. The adult carpet beetles only live for four to six weeks.

How do you get carpet beetles?

Carpet beetles are the source of the eggs. They come from various sources, the most common being shopping. They can also be found in flowers, animal fur, skins, and contaminated fabrics and furnishings.

Generally speaking, if you see carpet beetles and their eggs around your home, they thrive in the environment. Carpet beetles can feed off dirty carpets, so if the problem persists, it is likely due to uncleanliness.

If you have carpet beetles, it is likely because of an infestation. Unfortunately, you cannot do much to prevent them from coming in, as they are brought in by items such as used furniture or clothing. 

How fast do carpet beetles spread?

Carpet beetles quickly spread throughout the home. They lay eggs on animal-based larval food, so they can quickly infest carpets, furniture, and other items in your home.

In addition, carpet beetle eggs hatch quickly, and the larvae can spread rapidly throughout a home. The eggs of a carpet beetle can take 10–30 days to hatch, and the larvae will feed on natural fibers for an additional 30–60 days.

The larvae are very small and difficult to see, so it is important to identify the signs of an infestation as soon as possible.

The Process of Life

Carpet beetles go through a complete life cycle metamorphosis, which means they change completely. They pass through four stages in their life cycle: egg, larva, pupa, and adult.

There are different species of carpet beetle with different life cycles. Some can cause a lot of damage very quickly, while others may take more time to do significant damage. 

The black carpet beetle is one of the most common species of beetles in North America. They share a similar life cycle with other types of beetles, but the eggs and larvae are the most damaging stages for homes.

It’s important to identify the particular species of carpet beetle causing problems in order to address the issue effectively.


Carpet beetles lay eggs in warm areas where the larvae can thrive. The carpet beetle’s life cycle starts with white eggs that are smaller than a grain of sugar.

Carpet beetle eggs are oval-shaped and a light brown color. They are typically found in clusters and can be mistaken for mouse droppings. Eggs hatch in one to two weeks, and the larvae become carpet beetles.

Larvae emerge from these eggs and feed on the fabrics, carpets, and other materials that make up the home.


Carpet beetle larvae are small, brown, and have a big appetite. They will eat most organic materials, including dead insects, pet fur, and feathers. This can often damage homes and businesses as they consume fabrics, carpets, wood, and other materials.


When a carpet beetle has reached its final growth stage, it will pupate. This process happens inside the last larval skin, often in a protected place like inside a crevice or in furniture folds. Carpet beetle pupation typically occurs in the springtime.

The carpet beetle eggs hatching into pupae can take anywhere from six to 24 days. The length of time will depend on several factors, including temperature and humidity levels in the surrounding environment. The pupae will remain inactive and will not feed during this time.


Carpet beetle adults are about the size of a piece of rice and have an oval shape. They can be brown, black, or yellow. Adult carpet beetles live for several weeks to a couple of months, and they mate and lay eggs.

Carpet beetle larvae in the house

Once the carpet beetle eggs hatch, the larvae will start to feed on various items in your home, including clothes, furniture, and even pets. The adults can also fly outside in search of pollen, so it’s important to watch them and catch them before they lay eggs.

Are carpet beetles notorious pests?

Carpet beetles can cause serious damage to your home and significant destruction to furniture and other objects in it. They feed on dark, shady areas, which often leads to them damaging fabric, wood, and other materials.

In addition to damaging natural fibers, carpet beetle eggs also consume materials that contain animal fibers, such as wool, silk, fur, cashmere, or synthetics. As a result, they have a chance to succeed. It does significant damage to the environment, textiles, and clothing.

How to Prevent Carpet Beetle Infestation in Your House

A carpet beetle infestation can be a huge problem, not to mention a huge hassle. The best way to prevent an infestation is to clean all carpets, rugs, and upholstery before treating them. This will remove any eggs or larvae that may be present and help get rid of the beetles.

  • Vacuuming the area immediately after treatment is crucial to eliminating the carpet beetle eggs. This will remove any eggs or larvae that may be present and prevent them from hatching and infesting your home.
  • Dispose of the vacuum bag after use, and clean all surfaces where eggs might be laid with a vacuum cleaner or steam cleaner.
  • When you have treated the area for carpet beetles, it is important to open the windows in your home for 20 minutes so that the chemical fumes can dissipate. This will help to prevent a future infestation and keep your family safe.
