Below are some of the best recommendations on how to get rid of carpet beetles with essential oils. Yes, you can live in a pest-free home without the need to spray toxic and foul-smelling insecticides for carpet beetles.
Cedarwood Essential Oil
Let us kick off this article on how to get rid of carpet beetles with essential oils by talking about one of the most effective all-natural carpet beetle insecticides and repellents.
It’s none other than cedarwood.
You can use cedarwood in a couple of ways: in block or chip form, and in essential oil form.
Cedarwood blocks and chips can be purchased from local hardware or home improvement stores. To use them, simply place them where you don’t want any larvae carpet beetles to hang around.
The chemical compounds in cedarwood that give it its characteristic woodsy odor can suffocate carpet beetles.
What’s more, they can also dissolve the outer protective coverings of larvae carpet beetles, causing them to die.
If your home is prone to a carpet beetle infestation, it’s a wonderful idea to invest in cabinets and furnishings that are out of cedarwood.
To refresh their smell and keep them effective against carpet beetles, wipe their surfaces with cedarwood essential oil every three years or so.
Speaking of which, you can use cedarwood essential oil to kill larvae carpet beetles. You may also spray it where it is likely for those hairy critters to hide in between meals.
Cedarwood essential oil can damage carpet beetle eggs, too.
You can also use cedarwood essential oil as an alternative to cedarwood blocks and chips.
All you need to do is put a few drops of it in a cotton ball. Place the cotton ball where it matters. Do not allow it to come into contact with your clothes as they may end up stained.
Aside from carpet beetles, cedarwood essential oil can also kill and repel many other pests. Some examples are lice, fleas, ticks, mites, ants, silverfish, mosquitoes, and flies.
Here’s one of the best brands of cedarwood essential oil available in the market…
Majestic Pure Cedarwood Essential Oil
Size: 4 ounces
Unlike other essential oils extracted from leaves, flowers, seeds, and peels, cedarwood essential oil is obtained from the wood pieces of cedarwood.
Such is done by means of steam distillation, which isn’t easy and cheap. That explains the price tag of Majestic Pure cedarwood essential oil.
Especially if you are into cruelty-free products, you will love the fact that this particular brand of cedarwood essential oil isn’t tested on animals. It also comes with a dropper for easy dilution or straight application.
Cinnamon Essential Oil
It’s no secret that cinnamon can make a number of baked goodies smell and taste phenomenal. But other than that, it can also make the lives of common household pests miserable.
That’s because cinnamon is both an insecticide and repellent.
You can use cinnamon powder for eliminating larvae carpet beetles. However, it can stain carpets, clothes, linens, upholsteries, and others.
This is why the best form of cinnamon for the job is the essential oil kind. It’s so concentrated that, according to a study, it can kill some insects better than DEET, which is an ingredient commonly found in many of today’s insect repellents.
Cinnamon essential oil is so powerful that you should avoid coming into contact with it. Otherwise, you may end up with rashes and even skin burns!
Diluting it with water is pretty much useless because cinnamon essential oil and water don’t mix. If there’s a need to dilute it, you have to do it using a carrier oil such as almond oil, coconut oil, sesame seed oil, or olive oil.
Going back to cinnamon essential oil as a home remedy for carpet beetles, many homeowners swear that it becomes more effective when mixed with a little dish soap after it’s diluted with a carrier oil.
Worry not if you cannot seem to find live larvae carpet beetles but you are pretty sure that they are around. You can use cinnamon essential oil as an insect repellent instead.
Spraying it on or around items that are out of natural fibers or contain animal products can keep them from serving as snacks to larvae carpet beetles.

Eugenol in clove essential oil also possesses insecticidal properties, which is why the essential oil is excellent for ridding the home of common household pests, including carpet beetles.
To deliver results, clove essential oil has to be sprayed directly to larvae carpet beetles. This means that you will have to locate them if you want to see them dead.
Many homeowners who are into DIY remedies and swear by the effectiveness of clove essential oil as an insecticide prefer to combine it with other essential oils with minty smells.
Such is to enhance its pest-killing properties and make their homes smell nice, too.
Before spraying clove essential oil on a surface, it’s a good idea to test it on an inconspicuous area first. That’s because it may stain or damage it, depending on the material.
Clove essential oil’s insecticidal properties have residual effects. This means that it will still spring into action days after you have sprayed it. It may no longer be able to kill carpet beetles alright.
However, it can still repel them. This is why you may regularly spray clove essential oil around items that you would like to safeguard from larvae carpet beetles.
By the way, aside from the essential oil, you may also use dried cloves as an insect repellent.
