As you can see from the above list, there are some essential oils that kill or repel most insects.

Cedarwood is a must, as well as orange, peppermint, and spearmint.

The good news is that these oils smell great to us, (well at least most people think so) but they are fatal to insects and bugs.

Why Cedarwood Is Effective at Repelling Bugs and Insects

Cedarwood is extracted from conifer trees, commonly known as pine trees that I’m sure you’re all familiar with.

It’s known to be toxic to most bugs and pests, making it an obvious choice to use when repelling these annoying pests.

The science behind this is that cedarwood blocks a compound called octopamine, which is essential to some insects to regulate their heart rate and other functions.

If they have the opportunity they will flee the area pretty quick when they detect cedarwood. Otherwise, they will die, and you may see evidence of this in the areas you spray.

The good news is that it’s not toxic to us or our pets. Although you always need to be careful using essential oils around pets and it’s best they keep their distance.

How to Use Essential Oils to Deal with Insects and Bugs

All you need to do is add a few drops to a spray bottle with some water and soapy solution in.

The soapy solution is good because soap is particularly good at grounding flying insects as it makes it hard, or impossible for them to use their wings.

As for how much you use of oils, soap, and water, it’s up to you how strong you want the solution to be.

Don’t go overboard on your first batch, just add a few drops of oil. Then give it a few days use and see how much of a difference it’s making to your plants.
