What Causes Carpet Beetles in Car? (Everything You Need to Know)

Did you find a carpet beetle infestation in your car? Feels disgusting, right? Carpet beetles are tiny pests that have different types. However, one trait is common in all of them. They cause irreparable damage. This blog is all about the causes of carpet beetles infesting the precious interior of your four-wheeler.

You might have carpet beetles in your car for a couple of reasons: because you have trash inside your car, because you’re not cleaning it often because you haven’t used it in a while, or because you parked it close to a plantation. Cars are just a cozy habitat for carpet beetles! But whatever the reason you can get rid of them by cleaning your car and using boric acid and specific carpet beetle sprays.

What Reason of Carpet Beetles Infesting the Vehicle?

Carpet Beetles in Car

Owning a car is always a privilege. Sitting on an elegantly covered seat, you enjoy driving your shiny roadster.

It’s all good and comfortable until one day. You see a nightmare unfolding in front of you. Nah, I am not talking about a Dracula appearance. I mean to mention carpet beetles. Yes, the fabric-munching pests.

Now, you are troubled. You probably ask yourself instant questions like WHAT, HOW, and WHEN? It surely is a face-palm situation, but luckily it is solvable.

We have highlighted the potential causes of a carpet beetle infestation in your car. Let’s take a look at what those are.

Reason 1: Food Remnants in Your Car

Your car can probably be your second home. Going to work, traveling, long road trips, ALL of it involves food and drinks. If the trash isn’t picked up and thrown away, not only will your car be dirty, but carpet beetles will also be attracted to it.

These microsized pests can feed on dry food and oil as well. If empty packets of Doritos are laying around in your car, or any other snacks, carpet beetles won’t shy from taking their toll from all this junk.

Trash in the car

It is very important to pick up the trash and dispose it of in effort to keep pests away.

Kudos to you if you are particular about not keeping any waste in your car. Sadly, that does not mean your car is free from beetle trouble.

Reason 2: Food and Drink Stains on the Synthetical Fabrics in Your Car

Carpet beetles feed on products that contain animal protein. These include leather, wool, silk, hair, etc.

However, their natural feed doesn’t include synthetic fibers. Wait. Did you take a breath of relief? Uh-huh. They still can nibble your car seat covers. Let me tell you how.

You can probably recall a lot of times you ate snacks in your car. Some crumbs MUST have fallen on the seat or the car mat. You might have unintentionally touched the seat with your oily hands. Synthetic fabrics absorb oil. Similarly, sometimes there is a drink spilled on the seat covers. All of this becomes food for carpet beetles.

Lack of cleanliness

It’s remarkable if you keep track of the cleaning schedule of your car. However, not vacuuming your car thoroughly is the same as welcoming carpet beetles.

Cleanliness is NOT confined to just picking up trash. It also requires detailed cleaning now and then.

There are a couple of factors that act as bonus points for carpet beetles. Those play a huge role in aiding an infestation.

Reason 3: Leaving the Vehicle inactive for a Long Time

Your car usage depends on your routine and requirements. If you drive your car every day, that’s good enough. If not, it will be parked and undisturbed. This can result in carpet beetles sneaking into the car. They love dark and placid spots.

A dirty car coupled with quietness and peace says HELLO CARPET BEETLES.

Car idle for a while

Make sure you take your car on a drive even when it’s not needed. Just to move it around and have some action. The purpose is to destroy the tranquility available to carpet beetles.

Reason 4: Plantation Car Parking

Adult carpet beetles feed on nectar and pollen. That’s the reason why they are likely to be found in flowers and areas of a plantation.

Cars are often parked under trees or near gardens. I think you should avoid that. Carpet beetles are more likely to invade your car if it’s near their feeding grounds.

They can enter your car and make it a breeding ground. After that, it will be A LOT of trouble. The females can hatch 35 to 100 eggs at once.

The larvae are so tiny. They won’t even be seen until you notice the carpets and fabrics on the seats chewed.


If it’s not possible to use your car for a considerable period, just make sure you don’t park it very close to a plantation.
Also, try to put a car cover on to maximize the safety from pests.
