Why Use Cinnamon Oil In Your Car To Repel Mice

There are some great reasons why cinnamon oil is a go-to mice repellent! In fact researchers at the National Institute of Health determined that cinnamon oil is a great repellent. Let’s discuss why!

Natural Alternative to Chemicals

Who doesn’t love a natural, chemical-free solution? Cinnamon oil is an essential oil that can deter mice in your car without endangering your health or your vehicle’s integrity. Unlike harsh chemicals, cinnamon oil is non-toxic and safe for you and your family.

Plus, it smells great!

Strong Scent Repels Mice

Cinnamon oil’s strong smell is repugnant to mice sensitive olfactory receptors! Their dislike for this potent smell makes it an effective rodent deterrent.

When using cinnamon oil in your car, there are a few methods you can try:

  • Cotton balls: Soak a few cotton balls in cinnamon oil and place them around the car, focusing on areas where mice might enter or hide.
  • Spray bottle: Create a mixture of cinnamon oil and water in a spray bottle (about 1 part oil to 10 parts water). Spritz the mixture in and around your car, targeting potential entry points and hiding spots.
  • Cinnamon-infused items: Consider using cinnamon-infused products like sachets, air fresheners, or even car diffusers filled with cinnamon essential oil. Just keep in mind not to overdo it, as the scent can be quite strong!

Eco-Friendly Solution

It’s 2023, and we all want eco-friendly solutions! Cinnamon oil doesn’t harm the environment, unlike some chemical rodent repellents. By using this natural essential oil, you’re making a positive impact on the environment.

Remember, the mice aren’t out to get you – they simply find your car a cozy hiding spot. So, try cinnamon oil to deter them but also take steps to clean up any food or debris that may attract rodents. That way, you’ll have a mouse-free car, and both you and the mice can coexist peacefully in your respective spaces.

Identify Entry Points

Mice are sneaky little creatures that can find the tiniest of openings to get into your car. Some common entry points include:

  • Gaps near doors and windows
  • Cracks in the garage
  • Crevices near pipes
  • Openings around the cupboards and drawers

First up, inspect your car thoroughly and locate these pesky entry points! Having this knowledge is essential before applying cinnamon oil effectively.

Indoor Application

Now that you know where the mice might be entering your car, it’s time to use the magical cinnamon oil to make sure they regret their decision! Here’s how to apply it indoor:

  1. Create a solution by mixing cinnamon oil with water at a ratio of 1:3 (1 part oil, 3 parts water)
  2. Fill a spray bottle with this mixture
  3. Spray the mixture directly onto the identified entry points (doors, windows, cracks, etc.)
  4. Place a cinnamon oil-infused cotton ball or sachet near the entry points
  5. Spray the mixture inside the glove compartment or under the seats to keep these furry intruders away

Pro tip: Reapply the solution every few days or whenever you feel the scent has faded.

  • Place cinnamon oil-infused cotton balls or sachets around the perimeter

Preventing Mouse Infestation

Sealing Entrances

You may have been a little cheesed off with mice getting into your car, well, let’s help you nip it in the bud! Mice have an incredible sense of smell and are attracted to food, so let’s first tackle the issue of sealing entrances.*

Check all the doors, windows, and potential crevices around your car that may provide access for mice. Make sure they are all tightly sealed, as they can squeeze through the smallest of gaps! Not only that, but also check for openings near pipes, the stove, refrigerator, and drain entrances in your garage.

And mice don’t just stop at your car, you may also find mice in your garage, shed or if you have an RV!

Proper Food Storage

Mice have a keen sense of smell, so storing food properly is essential to repel them. Proper food storage in your car is a key step in avoiding infestations, especially if you tend to snack on-the-go.

Use airtight containers to keep any food items in your car and keep those tiny troublemakers at bay!


You’ve seen how cinnamon oil can be an effective and natural way to repel mice in your car. As someone whose looking for a natural solution, this is the answer for you! Remember, mice are not fond of strong scents, and cinnamon oil is precisely that! So, let’s recap the best ways to use cinnamon oil in your car:

  1. Apply cinnamon oil directly: In a spray bottle, dilute the oil with water, and spray it around your car’s interior, especially in hidden corners and compartments. Don’t forget the engine area and the tires!

  2. Cinnamon oil-infused objects: Objects such as cotton balls, fabric scraps, or small sachets can be infused with cinnamon oil and placed strategically inside your car. Make sure to replace these items occasionally to maintain their effectiveness.

From personal experience, I’ve found that using cinnamon oil not only helps repel mice but also gives a pleasant aroma to your car. So, you’re achieving two goals at once: driving mice away and refreshing the scent in your vehicle! (Not a bad deal, huh?)

The effectiveness of cinnamon oil to repel mice can vary depending on the concentration of the oil and the frequency of application. However, combined with proper car maintenance and cleanliness, it can be a powerful tool in your arsenal.

In conclusion, cinnamon oil is a great way to keep mice out of your car while providing an aromatic ambiance to your vehicle.
