Mice In Car: How to Get Rid of a Mouse in a Car

Table of Contents

Have you been driving less than usual lately? Maybe you have a car or RV that’s been sitting around for a season or two, either tucked safely in the garage or hanging outside under a tarp. As your car sits, the hood becomes a comfortable and enticing opportunity for creatures seeking asylum from the temperature. 

While mice might be small and unassuming creatures, they can cause real big problems for your automobile. One sole mouse can cause upwards of thousands of dollars to your car in just a couple of days! They’re also unclean, disease-carrying creatures.

Mice can heavily damage cars. If you suspect a mouse is living in your car, don’t fret—there are a number of ways to evict this loathsome loafer.

Mice in Cars: A Dangerous Pest

Mice can cause a lot of damage to your car. They carry diseases, gnaw engine wires, shred the gauze in your air vents, and chew holes in your upholstery. Mice can also cause major aesthetic damage and leave feces strewn about your vehicle. They can cause major vehicle malfunctions that cost thousands of dollars to fix.

Mice In Cars: The Telltale Signs

As a car owner, you will greatly benefit from keeping constant vigil for any rodents that have squirmed their way into your vehicle’s engine compartment, interior segments, or trunk. Mice view parked automobiles as pristine nesting spots—they enjoy air filters, dry trunks, and vents to build nests and store food.

Droppings & Urine Smell

You may notice odd or unpleasant smells emanating from your car, especially if you’ve seen mouse droppings or urine spots. The smell could be coming through your air vents or engine bay, where the mice are living and nesting. If you hear any strange sounds, especially when you turn on your heater or fat, it might indicate that rodents are nesting somewhere in your vents.

Since mice are living creatures and they need to eat, you might notice small collections of birdseed, dog food, or other items strewn about your car. This may give you an inclination of where they’ve built their nest, but it’s always a good idea to check under the hood and make sure they haven’t caused any extreme damage. The professionals at Hama Pest Control can properly identify mouse droppings and help you get rid of your problem.

Damaged Car

When mice live in your car for any amount of time, they cause interior structural damage. They can easily chew through wiring, insulation, filters, and more, causing a need for replacement. As discussed above, they can also bring with them a strong and foul odor, churning the smell of urine through your vents. Mice carry diseases, and they’re more than an aesthetic and structural problem. They can trigger allergies, cause illnesses, and make driving generally unsafe.

How to Get Mice Out of Your Car

Depending on the season, many people are out there Googling “how to get rid of mice in cars.” While there might be pages and pages of details, the recommendations sometimes lean more silly than practical. There are many ways to get rid of mice.

Mice are destructive nuisances, and any time you leave your car unattended for long, you run the risk of a minor infestation (especially if you park outdoors). There are a few ways to get mice out of your car, though in most cases you should consider calling a professional.

Remove Any Food Sources

Minimize your risk of an unwanted pest by minimizing the amount of food you keep in your vehicle. Don’t leave snacks in your car, sealed or otherwise, and try not to eat in your car if you park it outside. Try to park over gravel or pavement and away from fields, wooded areas, dumpsters.

Regularly inspect your car for signs of infestation. It’s a good idea to tidy up your vehicle weekly and not leave trash or other items under the seats. Look through your trunk, your engine compartment, and check your undercarriage for any signs of rodents. If you notice any strange smells or sounds, immediately investigate them. Vacuuming your car out regularly is also a good rule of thumb, as that will get rid of anything lingering in your vehicle that the mice might be attracted to.

Set Up Snap Traps

Once you know you have a mice problem, the next step is to remove them from the situation and gain control of your vehicle again. To start, set up mice traps (in safe spots) to get rid of the rodents. After you set up the traps you can spray down your car with a solution of 10 percent distilled bleach disinfectant, and wipe everything down. Traps will typically take care of the problem, though when it comes to vehicles it’s not recommended to use live traps because the animal could get scared and defecate/urinate.

Keep the Hood Wide Open

The hood of your car is a warm and inviting place with lots of little nooks and crevices for mice to stay. They love to build nests in and around your engine, especially during the cold months of the year where they are seeking shelter. You can attempt to make your vehicle less appealing by popping the hood and keeping it open, especially if you keep your car in the garage. It removes the “roof” of the mouse’s potential home, providing less shelter where they are able to nest.

Use Odor Repellents

You can treat the interior of your car with an array of natural essential oils or other available commercial products that will make your vehicle less appealing to mice and other rodents. There are essential oils that mice absolutely hate, such as peppermint oil, cloves, or cayenne pepper. You can spray your interior with these oils, as well as spray your hood and undercarriage, to keep the furry invaders at bay. There are lots of other pest control odor repellents out there with various uses.

Potential odor repellents for mice include:

  • Irish Spring Soap
  • Pine Sol
  • Dryer Sheets
  • Brillo Pads
  • WD-40

Wash Your Car Regularly

Regularly cleaning your car inside and out is a great way to deter mice. If you keep the interior cleaned and vacuumed there will be less appealing items for your mice to find, and if the exterior is cleaned and freed of any potential debris it will be difficult for the mice to find a way in. 

Scare the Mice Off With Pets

Having a cat is always a good call to deter mice. If you keep your car in the garage, consider installing a little pet door so that your cat can safely get in and out and scare mice away. If you have an outside cat, consider parking your car near where they like to hang out, and hopefully they will take care of the rodent problem for you!
