Peppermint Oil for Roaches: Does Peppermint Repel Cockroaches?

Published by Vijay Singh on

Probably, you’re facing a cockroach infestation in your house. Am I right?

There are many roach killers available that effectively kill these pests, but it’ll be awesome if we can just repel them using a non-toxic repellent.

In the list of 10 natural insect repellents published by the American College of Healthcare Sciences, peppermint essential oil is one of them.

But, they did not talk about whether it is effective against cockroaches.

So, let’s find out.

Does Peppermint Repel Roaches?

Does peppermint oil repel cockroaches

Yes, peppermint oil repels cockroaches.

In the Cockroach Control Manual published by the University of Nebraska, peppermint is one of the herbs that effectively repel roaches away.

This phenomenon is also tested by Katia A. Mafra Spencer in the Project Cockroach Push and Pull under the California State Science Fair. In this project, it was clearly shown that a savory dollop (peppermint as a key ingredient) act as a strong repellent for cockroaches.

Does Peppermint Oil Kill Cockroaches?

Peppermint spray repels these pests, but is it a good way to completely eliminate them from the earth?

No, peppermint cannot kill cockroaches.

It only acts as a repellent when used properly. Even, if you do not use it properly, it can also become a poor roach repellent.

Can You Get Rid of Cockroaches with Just Peppermint Spray?

Peppermint works as a good repellent, but if you want to get rid of these pests by using only this repellent, then you don’t want to hear the answer.

This can work on a few roaches, but if you are facing a heavy roach infestation, then using just peppermint spray is not going to help you.

If this is the case, then you need to take help of cockroach killing baits or help of some professional exterminators.

Professional exterminators charge a good amount of money; some are costlier than others. So, if you are thinking about taking help of them, then do not just settle on any exterminator. Get exact free quotes from multiple exterminators, and then hire the best one according to your budget.

How to Make a Peppermint Spray

Peppermint oil and cockroaches

There are various ways from which you can make your own peppermint repellent spray.

The one recipe is shared by Dr. Greg Koob from Hawaii Horticulture.

The requirements are:

  • 1 gallon of warm water
  • 2 tablespoons of liquid soap
  • 2 teaspoons of peppermint oil

Now, you just need to put them together and mix properly. Now, fill this peppermint soap spray in a spray bottle, and you’re good to go.

Dr. Rober Stauffer, Area Extension Specialist also shared a similar recipe of making roach repelling peppermint spray.

Here, you need to make a mixture of 3 ounces of peppermint oil to the 1 gallon of water.

After creating this peppermint oil mixture, fill this in a spray bottle.

Now, spray directly on the roaches, and the places where you suspect their activity.

How to Get Rid of Cockroaches

Peppermint is not an excellent roach repellent; therefore, you will need to think about it in a different.

According to the Department of Health of New York State, you must take away their food, hiding places, and water to eliminate them from your house.

To completely remove these pests, you must know what types of roaches are present in your house, and how to deal with them. The University of California’s Statewide Integrated Pest Management Program has shared some valuable information and you should take a look at it.


Peppermint essential oil is very refreshing, but when it comes to cockroach control, it is not very effective.

So, if you’re thinking about using it, then you may have to use a few other methods along with it.

I have used peppermint oil and other essential oils to kill roaches. I mix it into Thieves cleaner and spot spray them on sight; almost immediately they flop over and die. However, it does not rid my oven of the infestation and because the spray dries quickly, it does not protect surfaces for very long. I’m trying a mixture of date syrup and baking soda, with a dish of water nearby.

Gluetraps gets roaches , but 2/3 weeks later they get away leaving bottom of legs on traps , can they still walk.,??

    It depends on how roaches escape and the condition of their legs. When glue traps get roaches, you can use a roach spray to kill them or if the glue trap gets a lot of roaches, then you can simply burn it. So the main idea is to kill these roaches before they escape from your glue traps. However, glue traps are not the best way to deal with them.
