8 causes of carpet beetles in house

Carpet beetle infestation is a recurrent problem in many houses. Every infestation is unique in terms of the cause and severity. However, one thing is common in all of them. They are extremely unpleasant to face.

The first step in solving a problem is knowing its cause. So, let’s discuss the causes of carpet beetles in detail.

Cause 1: Openings

Adult carpet beetles feed on nectar and pollen. That is why they are found in gardens and plantations. How do they come to your house? Can they fly? A not very comforting answer is YES, they can.

Carpet beetles will see an open window, a door, or crack as a welcome sign. They will fly straight in. That is when the nusiance starts

Cause Openings

Cause 2: Cozy spots

Once carpet beetles come to your house, they mate near light sources. The females lay eggs in warm sites where food is in abundance.

This poses a real threat to your carpets, furniture, and pantries. The larvae hatch and feed in such dark and cozy spots.

In short, your house provides an ideal habitat to carpet beetles.

Cause 3: Natural fibers

Carpet beetles feed on animal-based products. This includes wool, leather, silk, animal fur, and human hair.

Ask yourself. Aren’t pretty much all these materials present in your house? I am sure the answer to this is YES.

This means your wool rugs and wool toys are carpet beetles’ natural feed. Sweaters made of wool are also their favorites.

Cause Natural fibers

The availability of these fabrics makes your house suitable breeding and feeding ground for the six-legged invaders.

Carpet beetles can infest synthetic materials as well. They aren’t included in their natural feed, but the oil stains and food remains on such items can attract carpet beetles.

Cause 4: Curtains

Do you know what else can fancy carpet beetles? Window curtains.

When carpet beetles fly in through your windows, their first hiding spot is probably the curtains.

They can lay eggs and stay safe there. If you touched the curtains with oily hands, they could absorb the oil. That’s how carpet beetles can also feed on them.

Cause 5: Carpets

You might have heard that if you don’t buy carpets made of wool, there will be no carpet beetle infestation. I hate to be the one to break it to you but, even synthetic carpets can be infested.

Let me explain it to you. So, you often eat snacks in your living room. Kids run around, munching on crispy chips. What happens is that the crumbs fall around and go unnoticed.

That’s exactly what carpet beetles notice. The larvae are so tiny. They easily hide in your carpets and nibble on them. Hence, synthetic carpets can be edible for them if they contain food remnants.

Cause Carpets

Cause 6: Dirty clothes

Are you habitual of doing laundry more than once a week? If yes, that’s cool. If no, umm, I would suggest you make this habit.

I agree that washing clothes is not an easy task. However, carpet beetles will ruin stained clothes if they are piled up for some time.

They will chew on them since the dirty laundry will probably contain animal protein like oil, human hair, or animal fur.

To safeguard your clothing items, keep them clean.

Cause 7: Lack of cleaning

As much as uncleanliness is unpleasant for humans, it is pretty attractive for pests

Carpet beetles love dust and dirt. If you don’t vacuum regularly, it’s about time you start doing it. That will also help in cleaning the carpets since larvae reside in them.

Pay attention to hidden spots like carpet edges and under the furniture. Carpet beetles look for undisturbed spots. You have to make sure those are thoroughly cleaned.

Lack of cleaning

Cause 8: No pest control

Don’t rely on DIY methods if you have a serious carpet beetle infestation. Take professional help when it comes to that.

Carpet beetles won’t be removed for good if you don’t let the pros handle the situation. They will breed again and keep you on your toes.
