Everything About Peppermint Oil and Mice
The Myth
There is no specific peppermint oil for mice but it should be admitted that this type of oil has been commonly used worldwide. The effect of using the oil varies. Some people say it works while some other say it doesn’t. You may think that mice hate the strong smell of peppermint but it is actually just a myth. Just like people, these animals are unpredictable. Some of them perhaps don’t like the smell of the oil but others won’t even care.
So, if you hear that peppermint oil can actually kill mice, it is just a myth. However, it does not mean that you cannot use it. The oil still serves as a natural mouse repellent if there are just one or two mice running around the house. For more serious mouse invasion, peppermint oil won’t ever work effectively. Setting traps or ask for an exterminator’s help gives the much more effective result.
So, does peppermint oil repel mice? The answer depends. For a few mice running around the house, it may work to make them go away. But, for a greater invasion, the answer is no. Bear in mind that not all mice are disturbed with the smell of peppermint oil.
The Truth
In addition to knowing the peppermint oil myth, it is better to also know the truth. Maybe lots of people have told you to use peppermint oil to deal with mice infestation. Is it true that mice really can’t stand the pungent oil?
When it comes to talking about peppermint oil for mice, there will be two different views. Some people believe that oil can be used as a mouse repellent and deterrent in the first place while others doubt that. Those who think that the oil works to get rid of mice have their own reasons. First, the smell of peppermint can confuse the critters in a way that they disguise the trails mice leave behind. The smell makes them away since they like to stay in places that they can navigate easily.
Second, it is widely known that the peppermint smell or the menthol contained in the oil can injure the rats’ nasal cavity. For us, the scent might be relaxing but for mice it is irritating. That is why mice naturally avoid places where there is a strong peppermint smell.
There are some reasons why the pungent oil fails to work as mice deterrent for some people. The most common reason is the scent of the oil is not strong enough. If you wish to irritate mice with peppermint oil, the scent should be very strong. Products of peppermint oil that you find at stores vary. Even, the scent is a different one to another. Some products have high oil concentration while the others don’t.
The second reason for the failure is to place the oil in wrong places. Some people just randomly place the oil-soaked cotton balls or spray the oils in areas that do not attract mice. Before applying the oil, it is better to make an observation place. Mark the areas in the house where you spot mice frequently. If, for example, you place the peppermint oil on your desk while mice are frequently spotted on the wall behind your cupboard, you will likely to fail.
Diligence is another possible problem. For your information, the smell dissipates after 24 hours depending on the level of oil concentration. Some high concentrated oil can last for 48 hours. It means that you need to replenish the spray every day even sooner. Don’t just leave it after setting it out otherwise it won’t help. So, it is clear that knowing how to use peppermint oil for mice is very important if you want to be successful with the natural method.
Problems and Hassles to Use Peppermint Oil
If you plan to use peppermint oil to overcome mice problem, you should also try to understand the problems and hassles that may occur. These matters become important parts to consider related to peppermint oil and mice.
The first problem that confuses the users is the vague instructions to use the oil. For example, there is no clear information on how much the oil to use for a specific area. The absence of clear information is probably due to the fact that peppermint oil is not specifically intended for controlling mice.
In addition to problems in using the oil, some hassles may occur, too. For instance, you need to provide cotton balls and soak them in the pure peppermint oil. After that, you need to place it in some areas around the house. The hassles won’t stop there as you need to replace the cotton balls once to three times a week. It is because the smell usually wears off from the cotton balls in more or less two days.
Final Words
As now you know the myths and truths of Peppermint Oil and Mice, you should not be confused anymore in using the method. As long as you use the oil properly with only a few mice, there is a chance that it will work. However, for more serious mouse attack, you should try other effective methods like mouse trap or bait station.





I like this idea with peppermint oil as mice repellent. I tried it a few times, both diluted and concentrated, and it helped me a lot.
Great to know that Peppermint oil works for you.
Thanks for sharing your feedback.
peppermint oil in pure strength really works in my camper. i often leave the bottle sit open in the kitchen and that keeps the smell around for a while. TRY IT
Hello Dennis,
Thanks for sharing your experience with preppermint oil.
I punch many (30-40) small holes in Altoid tins, put a couple of cotton balls in each tin and put 15-20 drops of peppermint oil on the cotton. I have used this successfully on outdoor furniture. If you place a cover over the furniture, the deterrent lasts for months.
I have been livinf off the grid for about 3 years now and due to a couple of not so far nieghbors that are reallyy messy ( garbage wise )ive had to deal with rat infestations and theres no getting around it or calling an exterminator cuaae they will juat be back a week later starting up a new colony, so ive tried almost every method that you read about online and for the most part all of them have truth to them, but like this article states location and consistency is one of the most important part of any trap\baits when it comes to rats and you do need alot of paitience. For peppermint oil its not a very effective product for the fact it wont last long, i do use it though for inside my walls and under my floor boards becuase both places are very contained the oil lqst about a week under rhe floor boatds and 2-3 weeks in the walls cuase if youve ever had rats digging passagewsys in your wallls then you knkw the fustrations.The best and easiest methods i foind for keeping rats away is keep the inside of your place tidy, keep food in a sealed tote, cans are fine left out, seal any holes you find with wire mesh if you can acces the holes that is it ccan be tricky getting to the holes somerimes but rats are extremely skitish creatures and for that reason alone can make them really hard to kill and it can ne annoying as all hell when you have them rerenovating your house very loudly all night and theres not much you can do about it but wait till they break throifj and then deal with the hole. Also i keel a couple basic rat traps out with and q garbage can in the ground filled with water near there runways and a rolling pipe at the top. Those traps work well. Glue traps typically wont work in winter the adhesive isnt as sticky and they usually gey away but not before leaving a gray rat blanket of hair on the trsp lol. The biggest help i evrr had though was getting a trail cam so i could see what was going on why or why not my baits\traps were working or not
