Finding a bug in your bed can be disconcerting, and many types of beetles like to live in beds for various reasons. Among these beetles are carpet beetles which feed on natural animal fibers, like those in sheets and wool blankets. How do they get there in the first place, and how do you get rid of them?
Do carpet beetles get in your bed? Carpet beetles can get in your bed and will feed off fibers such as pet hair, wool, silk, and cotton, making the blankets and sheets on your bed a perfect place for carpet beetle larvae to eat. You’ll want to spray non-toxic insecticides and essential oil repellents to get rid of them.
In this article, we’ll discuss how to identify carpet beetles to make it easier for you to recognize them when you see them. Then, we’ll go over some of the habits of carpet beetles and ways that you can repel, kill, and remove them from your home.
What Are Carpet Beetles?
So, what makes carpet beetles different from other bugs, and why do they appear in your home?
Carpet beetles, or dermestids, are one of the most common indoor pests. The name dermestid comes from the Greek word for “skin” and “eat,” since larvae prefer to eat animal skin, fabric fibers, and hair.
So, let’s talk about the specifics of carpet beetles so that you can positively identify them.
What Do Carpet Beetles Look Like?
Carpet beetles are round or oval-shaped with a hard outer shell, and are either black or have a spotted calico pattern with yellow, black, and white scales. The larvae are a yellow-brown color, and they have hundreds of tiny hairs.
They also have long hairs near the end of their bodies, which look like a ponytail.
How Big Are Carpet Beetles?
Carpet beetles are tiny and the adult and larval sizes depend on the type of carpet beetle. Still, no variety will ever get any larger than 1/2 in (1.27 cm) long.
Black carpet beetles are usually 3/16 in (4.76 mm) long at full adult size, but when they are larvae, they can be up to 1/2 in (1.27 cm) long. Varied carpet beetles are more petite than black carpet beetles and are 3/16 in (4.76 mm) to 1/4 in (6.35 mm) long when they are larvae. As adults, they’re 1/8 in (3.18 mm) long.
Where Do Carpet Beetles Come From?
Adult carpet beetles can fly and are attracted to light. Carpet beetles may fly in through a door or unscreened window, and if they find a suitable food source for their larvae, they may lay eggs near that food.
Carpet beetles may also come inside domestic spaces via food, fabric, feathers, or animal hides.
They prefer to lay eggs in small crevices, making beds, rugs, and other areas with pet hair or natural-fiber cloth some of the primary places they colonize.
What Do Carpet Beetles Eat?
Adult carpet beetles only eat pollen, but the larvae have a more diverse diet. They commonly eat natural fibers like wool, cotton, and silk. They also eat dry cereal foods, pet foods, animal hair, leather, dry animal carcasses, and dried flowers.
Because only the larvae eat fibers, adult carpet beetles can’t stay alive in your home for long.
Carpet Beetle vs Bed Bug
So, if carpet beetles live in beds, does that mean that they are bed bugs? The short answer is no.
Carpet beetles are not bed bugs, and they’re not even related. Bed bugs feed on blood, while carpet beetles eat fibers. Bed bugs are also lighter in color, and they don’t have a round shell as carpet beetles do.
There are plenty of differences between carpet beetles and bed bugs. Let’s take a look at the differences so you can tell the difference between them.
Is a Carpet Beetle a Bed Bug?
Although carpet beetles can live in beds, they’re different from bed bugs. The most marked difference between the two is that bed bugs have pointy mouths that bite and suck the blood.
Carpet beetles, however, cannot bite, although their larva may cause an allergic reaction.
Difference Between Carpet Beetle and Bed Bug
|Characteristics||Carpet Beetle||Bed Bug|
|Larvae||Hairy||Smooth and wormlike|
|Length||Between 3 mm (1/8 in) and 5 mm (3/16 in)||4.5 – 5 mm (3/16 in)|
|Shape||Round, protruding shell with wings||Flat body with ridges and no wings|
|Color||Matte brown, black, or calico||Almost translucent amber brown|
|Signs of Infestation||Shed skins, dead adult beetles by windows, holes in your fabrics||Black smears on your mattress or sheets|
|Food Source||Animal hair, skin, pet food, dried flowers||Blood|
Types of Carpet Beetles
The most common types of carpet beetles are the black carpet beetle and the varied carpet beetle. Varied carpet beetles are round, and have a calico color, while Black carpet beetles have black or dark brown color, and their bodies are much more oval-shaped than varied beetles.
Are Carpet Beetles Harmful?
Even though carpet beetles aren’t blood-suckers like bed bugs, you may still wonder if they are harmful or poisonous.
Carpet beetles are not harmful, although their larvae can cause a minor allergic reaction if they contact human skin. Only some people are allergic to carpet beetle hairs, so you may not even notice the carpet beetles in your bed.
Do Carpet Beetles Bite?
People who come into contact with carpet beetle larvae may have small red welts on their legs that look like mosquito bites. Only the immature larvae of carpet beetles cause these welts because larvae have fine hairs that irritate human skin and often cause an allergic reaction.
Do Carpet Beetles Live in Beds?
Finding any bug in your bed is a frightening experience, especially if it seems like the bugs are intentionally setting up camp on your mattress.
Carpet beetles often live in beds. Since they’re attracted to pet hair, dead skin, and natural fibers like wool, they often feed on blankets, sheets, and feather pillows. If you find evidence of carpet beetles, you’ll want to spray a non-toxic insecticide to get rid of them.
Let’s talk more about why carpet beetles might be living in your bed.
Why Are Carpet Beetles in My Bed?
Carpet beetles, like every organism, need to eat. They’re attracted to the smell of animal hair, natural fibers, and dead skin, which makes your bed a prime spot for them. And, because your mattress is thick and private, they can live in your bed undetected for a long time.
What Attracts Carpet Beetles in Your Bed?
If you let your dog or cat sleep with you, large deposits of animal hair in your bed might attract carpet beetles. Wool or silk bedclothes and blankets are also a common food source for them.
If you don’t clean your sheets very often, carpet beetles may also eat dead skin or crumbs left between your sheets.
Signs of Carpet Beetles in Bed?
If you think that you may have carpet beetles in your bed, you should look for:
- Small holes in your bedclothes where carpet beetles have eaten the fabric.
- Hairy larvae
- Shed shells of the beetles or larvae underneath or around your furniture.
Carpet Beetle Eggs in Bed
If you think you may have carpet beetles in your bed, check for eggs in your pillowcases, under your mattress, on your box spring, or between your blankets. Carpet beetle eggs are tiny, ovular, and white. Usually, female carpet beetles will lay 50-100 eggs in one clutch, so you’ll likely see a large cluster of them.
How To Get Rid of Carpet Beetles in Bed?
Getting the carpet beetles to leave your bed is simple. All you have to do is clean your bed area very well and change some of the fibers you keep in your bedroom.
To get rid of carpet beetles, do the following:
- Wash your bedclothes in hot water.
- Gather cotton, silk, felt, feather, and wool items in an airtight container or bag.
