Wouldn’t it be great if insects didn’t like the smell of indoor air?
Then they’ll be happy to avoid your house!
These 4 essential oils that repel insects can make a dream come true. I use it in diffuser blends, so its people-friendly, bug-busting scents can fill your indoor air and keep pests out of your space.
The main essential oil in this mixture might surprise you. It’s catnip! (Yes, the crazy kitty maker!)
Catnip essential oil repels insects – especially mosquitoes!
Some catnip oils contain high levels of Nibitalactone, Which has been shown in studies to repel flying insects, including mosquitoes. One study showed that the percentage of expulsion is over 95%!
In this blend, I combine catnip rich in nibitalactone with three other essential oils that repel insects. I’ll talk a little more about each of these oils after the recipe.
Diffuser blend “Keep the insects away with catnip”
- 5 drops of catnip essential oil (Nepita Kataria)
- 2 drops of cedarwood essential oil (Juniperus virginiana)
- 2 drops of Palmarosa essential oil (Symbobojon Martini Where Dead)
- 1 drop of patchouli essential oil (Caplin Bogostemon)
This blend features a floral and herbal scent of catnip, with sweet, woody and earthy notes.

You have already learned why Catnip is so effective against pesky pests!
Let’s talk about the other bug repelling essential oils in our diffuser blend.
Cedar wood oil
Juniperus virginiana
Cedar wood is popularly used in cupboards to keep moths out of clothes. You can find cedar boards to hang on clothes hangers, pellets for drawers, and cedar spray to protect your clothes. (Some of the cabins are even made of cedar!)
And moths aren’t the only insects that do not like cedar wood. Mosquitoes, ants, fleas, flies, and spiders also tend to avoid it.
Cedar wood component Cedrol It likely plays a big part in making him so repugnant to bugs.
Palmarosa essential oil
Symbobojon Martini Where Dead
Contains Palmarosa Geraniol, Which has been shown to repel a variety of microbes, fungi and pests – including mosquitoes.
Diffusion Palmarosa oil can also help purify indoor air, reducing the presence of airborne microbes. You will love this oil if you occasionally get a cold in the spring!
Patchouli essential oil
Caplin Bogostemon
In one study, patchouli was among the 38 most effective essential oils studied to repel mosquitoes! This explains why it is such a popular natural insect repellent.
We can thank her main ingredient Patchouli For this. Research shows that it repels several types of insects.
What to do if you are bitten by an insect
On the occasion I forgot my repellant and got a bite, I like to use essential oils to soothe the itch.
Try Essential Itch Away Spray (from our blog!), Made with aloe vera, lavender, peppermint, and a couple of other skin-soothing oils.
