How to Get Rid of Carpet Beetles. Everything You Need to Know!

Do you think you might have Carpet Beetles? Act quickly! This ultimate guide will teach you about the different carpet beetles types, how to remove them and how to make sure they never infestate your carpet!

Adult carpet beetles feed on pollen and have the ability to fly. Hence, they can enter your home through cracks, windows or doors. They can also come in with flowery plants or hitch a ride on an animal’s skin. These can already be present in a used furniture item you bring in your home.

Once carpet beetles are indoors, they are likely to mate near light sources. The females prefer laying eggs where food sources for the larvae are abundant. So, I would say a carpeted home is one of the best options for them.

Why do they spread so quickly?

After carpet beetles enter your home, they invade different rooms very rapidly. Why does this happen? The answer to this lies mostly in the study of their reproduction habits.

The females can lay 35 to 100 eggs at once. This massive figure hints at the trouble larvae will cause after they hatch. The infestation will be extremely quick since they will be so many. You probably won’t be able to spot them due to their tiny size, but they will gnaw on your carpets all along.

Another reason for their vast and speedy spread in our home environment is the availability of their favorite feed. This includes a variety of items containing animal protein like wool, leather, fabric material and hair. They are also attracted to synthetic fibers that are spilled over with food or oil just like our carpets.

Carpets also provide them with their ideal living and feeding environment that is dark and undisturbed. This lifestyle coupled with the availability of vast carpeted areas results in the vigorous spread of carpet beetle larvae in your furnished home.

Are carpet beetles seasonal?

Do you think if carpet beetles ever take a break? I am sorry but the answer to this is negative.

Carpet beetle larvae hatch in spring or early summer. Due to their long life span, they aren’t exactly seasonal. Unfortunately, they can have you on your toes all year long. I agree that it sounds inconvenient and must be so frustrating.

Adult carpet beetles rise in spring. Keep in mind that their main food source is pollen, so it does make sense. Generally, carpet beetles do tend to be more active in warmer weather. Those hiding in vents and attics come out when it gets hot.



A study showed that carpet beetles reproduce at a much quicker pace in higher temperatures. This means you have to be more cautious in summers. Your home can be exposed to hundreds of larvae and resulting infestations.

Where will they most likely spread in your house?

Their favorite hideouts are dark and quiet places.

Other than the floor carpets, these include atticsbasementsair ducts or similar areas. They are also known to feed on dead insects in the walls and chimneys. This is one of the reasons why an infestation can be overlooked.

Adult carpet beetles can be found in flowers and plants. The larvae are greatly known for their ability to digest keratin that is found in animal-based materials.

That species is specifically named as furniture carpet beetles. Those tend to penetrate in your furniture, feed on hair, upholstery or padding. They will widely spread without any warning signs for quite some time.

Carpet beetle larvae also feed on grains or dry food. This poses a real threat to your pantry full of cereals and snacks. I am sure no one likes pests near food items. So, preventive measures are necessary.

Some carpet beetles also attack warm clothes as they are put away for the summer. They have a blast in there by feeding off your precious sweaters and coats. An infestation along with resulting damage can be spotted in the form of large holes in the garments.
