One of the first things I checked after finding carpet beetles in our house was the stack of blankets we’d been storing in a closet.
It probably sounds strange until you think about it.
Blankets spend long periods folded up.
Many are made from natural fibers.
Some aren’t touched for months.
From a carpet beetle’s perspective, that’s a pretty comfortable place to leave the next generation.
The good news is that simply owning blankets doesn’t mean you’ll end up with carpet beetles.
The bigger question is what kind of blankets you have and how they’re being stored.
Yes, Carpet Beetles Can Live in Blankets
The answer is yes.
Carpet beetle larvae can live in blankets if they provide food and shelter.
They’re especially attracted to blankets made with natural animal fibers because those materials contain proteins the larvae can digest.
Synthetic blankets are generally less appealing, although they can still collect enough hair, lint, and organic debris to attract larvae.
Wool Blankets Need the Most Attention
If I owned several expensive blankets, the wool ones would be the first I’d inspect.
Wool has long been one of the favorite food sources for carpet beetle larvae.
That doesn’t mean they’ll ignore every other blanket in your house.
It simply means wool deserves a closer look, especially if it’s been folded away for a long time.
Blankets in Storage Are More Likely to Have Problems
A blanket you use every evening gets shaken out, moved around, and washed fairly often.
A blanket sitting on the top shelf of a closet for two years is a completely different story.
The longer fabrics remain undisturbed, the more time carpet beetles have to complete their life cycle without anyone noticing.
That’s one reason seasonal blankets deserve a quick inspection before they’re used again.
It’s Not Always the Blanket They’re Eating
One thing that surprised me while learning about carpet beetles is that the blanket itself isn’t always the main attraction.
The larvae may be feeding on:
- Pet hair.
- Human hair.
- Lint.
- Dead insects.
- Dust mixed with natural fibers.
Those materials slowly collect while blankets sit folded or stored.
That’s why simply washing the blanket once may not solve the whole problem if the surrounding storage area hasn’t been cleaned.
Check the Blanket Before You Put It Away
This has become a habit I’d recommend to anyone.
Before folding a blanket for long-term storage, I’d give it a quick inspection.
Look for:
- Small holes.
- Shed skins.
- Tiny fuzzy larvae.
- Adult carpet beetles.
- Heavy lint or pet hair.
Finding any of those early is much better than discovering damage months later.
If you’re unsure whether you’ve found a larva, my guide explaining what carpet beetle larvae look like shows exactly what to look for.
Don’t Forget the Closet
When people find carpet beetles in a blanket, they often focus only on the blanket.
I’d be much more interested in the closet where it was stored.
Closets naturally collect dust, lint, and clothing made from natural fibers.
They’re also quiet places that don’t get disturbed very often.
That’s exactly why carpet beetles like them.
If you’ve found activity there, Why Are Carpet Beetles in My Closet? Common Causes and Solutions explains what I’d inspect next.
Washing Helps, But It Isn’t the Whole Solution
If I found carpet beetles in one of my blankets, the first thing I’d do is wash it if the care label allows.
For delicate wool blankets, that may mean dry cleaning instead of tossing it into the washing machine.
Cleaning the blanket removes a lot of the hair, lint, and debris that larvae depend on.
But I wouldn’t stop there.
I’d also clean the shelf, storage bin, or closet where the blanket had been sitting.
Otherwise, it’s possible for the next generation to develop in the exact same place.
Vacuum the Storage Area Too
One thing I’ve learned is that carpet beetles rarely stay confined to a single item.
If they’re using a blanket, there’s a good chance they’re also taking advantage of nearby debris.
That’s why I’d vacuum:
- Closet floors.
- Closet corners.
- Baseboards.
- Shelves.
- Storage bins.
- The floor just outside the closet.
A strong vacuum removes far more than dust.
It helps remove hair, lint, shed skins, eggs, and even some larvae before they have a chance to mature.
I explain why I consider this one of the most important tools in Best Vacuum for Carpet Beetles Why Powerful Suction Matters.
If you’re shopping for one, I’ve had the best experience with the Bissell Pet Hair Eraser Allergen Lift-Off because its powerful suction and detachable canister make it much easier to clean closets, shelves, furniture, and other places where carpet beetles like to hide.
Sealed Storage Can Prevent Future Problems
If you only use certain blankets during part of the year, I’d think about how they’re stored.
Instead of leaving them exposed on an open closet shelf, sealed plastic storage containers can make life much harder for carpet beetles.
They’re also much easier to inspect when you pull them back out months later.
That small change can help protect expensive blankets from becoming an easy target.
One Blanket Usually Isn’t the Only Clue
If I discovered larvae inside one folded blanket, I wouldn’t assume the infestation ended there.
I’d immediately inspect nearby:
- Sweaters.
- Scarves.
- Coats.
- Bedding.
- Shoes.
- Upholstered furniture.
Carpet beetles are opportunists.
If several natural-fiber items are stored together, they’ll often use more than one of them.
That’s exactly why I recommend reading Where Do Carpet Beetle Larvae Hide? Common Hiding Places after finding evidence anywhere in the house.
Sometimes a Spray Is Worth Considering
Cleaning should always be the first step.
Once you’ve removed as much hair, lint, and debris as possible, an indoor carpet beetle spray can help treat cracks, baseboards, closet edges, and other areas where carpet beetles continue hiding.
I wouldn’t depend on spray alone, but it can be a useful part of an overall treatment plan.
I talk about realistic expectations in Does Carpet Beetle Killer Spray Actually Work?.
If you decide to use one, the Carpet Beetle Killer Spray for Indoor Use is designed specifically for carpet beetles and their larvae when used according to the label directions.
What I’d Do If Carpet Beetles Got Into My Blankets
I’d wash every blanket that could safely be cleaned.
I’d vacuum the closet from top to bottom.
I’d inspect nearby clothing and bedding.
Then I’d continue checking that storage area over the next several weeks.
Carpet beetles are much easier to eliminate when you interrupt their life cycle instead of waiting until new adults begin appearing around the house.

Frequently Asked Questions
Can carpet beetles damage blankets?
Yes. Carpet beetle larvae can damage blankets made from natural fibers such as wool, especially when the blankets are stored for long periods without being disturbed.
Can carpet beetles live in fleece blankets?
Most fleece blankets are made from synthetic materials, making them much less attractive than wool blankets. However, larvae may still be attracted if the blanket contains enough pet hair, lint, or other organic debris.
Should I throw away blankets with carpet beetles?
Usually not. Most blankets can be cleaned and saved if the infestation is discovered early. It’s equally important to clean the surrounding storage area so carpet beetles don’t return.
How should I store blankets to prevent carpet beetles?
Wash blankets before storing them, make sure they’re completely dry, and keep them in sealed plastic storage containers whenever possible. Periodically inspect stored blankets if they remain packed away for several months.
Can washing blankets kill carpet beetles?
Washing can remove or kill many carpet beetles, larvae, and eggs depending on the fabric and washing instructions. Even so, you should still inspect and clean the surrounding closet or storage area because that’s often where the infestation continues.
