Written by: Rita Stadler January 01, 1970 Pest Control & Prevention

Mice in cars are a common problem, especially in the fall and winter when they’re looking for a warm place to nest. If you’ve ever had the unpleasant experience of finding one of these pests in your car, you know how important it is to prevent mice from returning to your vehicle.

Rodents can cause a lot of damage to your vehicle including gnawing on car wires, chewing up upholstery, and leaving behind droppings that can stain and ruin surfaces. They can also spread disease, which is especially concerning if they are living in a car that you and your family use frequently.

If you begin to notice signs of these critters, it’s time to take action immediately. Whether you are looking to keep mice away from your car that’s currently in storage, from a car restoration project you’re working on, or simply make sure they stay away from your everyday driver, we put together some pest control tips to help.

How to Keep Mice Out of Your Car

Keeping mice out of your car can save you from the hassle and cost of repairs. Some people try using mothballs, dryer sheets, or peppermint oil as DIY solutions, but these methods all have inconsistent results and can leave behind harmful chemicals and unpleasant odors. Common mouse traps like snap traps and glue boards have also been old standbys but they only stop the unlucky mouse that gets caught, doing nothing to stop friends and family.

Here are some practical tips to help you deter rodents from making your vehicle their home:

  • ● Keep both the interior and exterior of your car clean
  • ● Close the windows, sunroofs, and the hood each time it’s driven
  • ● Use a botanical rodent repellent inside of the vehicle
  • ● Seal potential entry points
  • ● Check the interior, the engine, and under the hood regularly to look for signs of rodents

How to keep mice out of a car: 6 steps

We go into detail on each of these tips below.

1. Keep Your Car Clean

Rodents are attracted to food scraps and debris, so keeping a tidy car will help to discourage them from wanting to move in. Regularly wash the exterior of your car and vacuum the interior to remove any potential food sources that could attract pests.
Clutter inside your vehicle provides perfect hiding spots for mice. Keep your car tidy and avoid using it as a storage space for items that can accumulate.

2. Close All Openings

Each time you park your car, make sure all windows, sunroofs, and the hood are closed and latched tight. Even small openings can invite rodents inside. This habit, though simple, can make a significant difference in keeping your car rodent-free.

3. Use Botanical Rodent Repellents

Use a botanical mouse repellent like Fresh Cab® in the interior of the vehicle. Fresh Cab pouches use essential oils to create a scent that’s offensive to mice but not to humans. Place these fast-acting pouches in your car’s trunk, under the seats, and in the glove box to deter rodents. These repellents are effective both for prevention and for dealing with an existing infestation.

4. Seal Potential Entry Points

Mice can squeeze through incredibly small openings, so it’s essential to seal any gaps or holes that might allow them access to your car. This is particularly important if you park in a garage or near areas where rodents are known to be present.

Inspect your vehicle for any gaps around doors, windows, or vents, and ensure they are properly sealed. If you park in a garage, check the garage door for any gaps or cracks that might allow rodents inside, and repair them as needed.

5. Perform Regular Inspections

Regularly inspect your car’s interior, engine, and under the hood for signs of rodent activity. Early detection allows you to take immediate action and prevent further damage to your car. Look for droppings, gnawed wires, or nesting materials.

By following these tips, you can significantly reduce the risk of mice infesting your car. Prevention is key to avoiding the mess and expense of dealing with rodent damage.

How to Keep Rodents Away from Car Restoration Projects and Stored Vehicles

Is there a car that when you see it, you get a rush? It takes you back to another time and place. Restoring a classic car is like preserving a little piece of history. A little piece of history that can purr like a kitten AND roar like a lion if you do it just right. The exterior of a collector car is the first thing most people notice, but we all know some of the most deviant details can be found under the hood and in the interior.

The Hidden Threat: Pests in Your Classic Car

Aside from the obvious challenges of finding the time, money, and parts required to restore your dream car, there can be a host of more insidious problems. One detail that often goes overlooked is pest prevention. Mice are happy to make their home just about anywhere, and a classic car that is parked more often than it is driven is mighty tempting. They will move into a vehicle, chew up upholstery and seat cushions for nesting materials, and leave droppings all over the place. They even gnaw on wires and other mechanical components to file down their ever-growing teeth! All of this can ruin any progress made on your restoration, and can lead to costly repairs and setbacks in your restoration project.

This is true for any vehicle that is placed in storage. You must be proactive in keeping these pests away from your car while it’s stashed away. The following methods, similar to the ones listed in the how to keep mice out of cars section above, focus on creating an environment that is uninviting and inaccessible to rodents and other pests:

  • ● Plant-Based Rodent Repellents – The best way to keep mice away from stored cars is by using a plant-based rodent repellent. Instead of luring them in with a baited trap or yummy-looking poison, repel mice away with a natural, fresh scent that overwhelms their little noses. Fresh Cab pouches will send them scurrying away before damage is done. Replace the pouches in your car every 30 days or when the scent begins to diminish.
  • ● Seal All Entry Points – Rodents can squeeze through incredibly small openings, so it’s important to thoroughly inspect your vehicle for any gaps, cracks, or rust holes that might allow them access. Pay special attention to areas around doors, windows, vents, and the undercarriage and seal any problem areas. If your vehicle is stored in a garage, inspect the garage door and walls for any openings. Repair any cracks or gaps to ensure that pests cannot enter the garage in the first place.
  • ● Elevate and the Vehicle – Elevating your vehicle on jack stands can make it more difficult for rodents to access it. Though rodents can climb, an elevated car can still reduce the likelihood of rodents climbing into the engine bay or undercarriage.
  • ● Cover the Tires – Consider using tire covers that are snugly fitted around each tire. This not only protects the tires from dust and dirt but can help keep rodents from climbing up into the car through the wheel wells.
  • ● Keep the Storage Area Clean and Clutter-Free – Pests are often attracted to clutter and debris, as these materials can be used for nesting. Keep the area around your stored vehicle clean and free of trash, boxes, or other items that could harbor rodents. Regularly sweep and clean the storage area to remove any food crumbs or other organic matter that might attract pests.
  • ● Regularly Start and Move the Vehicle if Possible – Even if your collector car is in storage, try to start it occasionally. The noise and vibration from periodic use can help deter pests from settling in. If possible, take the car for a short drive every few weeks. This not only keeps the battery charged and the engine in good condition but also disturbs any pests that might be considering your vehicle as a home.

How to Get Rid of Mice in Your Car

If you spot a mouse in your car or start to see or smell signs of these pests (like the smell of a dead mouse), don’t panic! You want to act quickly, however, before the problem leads to an infestation. There are a few simple steps you can take to get rid of them.

  • 1. Locate the Mouse and Check for Nests – Begin by thoroughly checking the interior of your vehicle for any signs of a mouse or a nest. Pay close attention to areas like the engine compartment, air filter, around the car battery, and underneath the vehicle. These are common places where mice might build their nests. Next, encourage the mouse to leave. Sometimes, simply driving the car, taking it through a car wash, or honking the horn can encourage the mouse to leave on its own. If you find a nest, hopefully, it will already be empty.
  • 2. Safely Remove the Nest – If you find a mouse nest, it’s important to remove and dispose of it safely. Follow the CDC guidelines for handling and disposing of rodent nests to avoid potential health risks. If you discover a dead rodent in your vehicle, use the CDC guidelines for safe removal and disposal. It’s important to handle this process with care to avoid contamination.
  • 3. Seek Professional Help if Necessary – If you can’t locate the mouse or its nest but continue to notice signs of pests, it might be time to seek professional help. A mechanic can thoroughly inspect your vehicle and address any hidden issues that could be attracting rodents.
  • 4. Prevent Future Infestations – Once you’ve resolved the issue, it’s essential to follow preventive measures to keep mice from returning. Regularly clean both the interior and exterior of your car to remove anything that could make it an attractive home for pests. Place Fresh Cab pouches throughout your car to repel mice. These pouches are available in-store or online and should be replaced every 30 days, or when the scent begins to fade.

By taking these steps, you can effectively deal with a mouse problem in your car and prevent it from happening again. Regular maintenance and vigilance are key to keeping your vehicle rodent-free.

Shop Fresh Cab in-store or online and stop rodents from causing costly damage to your vehicles.

If you have a camper or RV, be sure to follow additional tips for keeping mice out of these larger vehicles. They can be even more vulnerable to rodent infestations due to their size and storage conditions.
