How to Get Rid of Mice In Car Vents/ Air Filters/ Dashboard?

Mice, rats, and other rodents get inside your vehicle from multiple inlets. The engine compartment is the first route to the rest of the car. Remember that the engine needs air, and mice can squeeze through a space as small as a dime. Thanks to the vacant spaces in an engine’s compartment, a mouse will find it easy to crawl up and find a nice warm location for nesting. 

Apart from the engine, rodents can also crawl through the tires and holes in the body panel. 

A mouse will then make its way to the vents, air filters, and dashboard from their point of entry. Undoubtedly, even one mouse can cause significant damages.

Some of the damage that mice cause include: 

  • Eating up insulation 
  • Chewing through hoses and electricals 
  • Tearing up upholstery and carpeting 
  • Stains from urine 
  • Nesting in the insulation 
  • Diseases that can spread to humans 

Even before you can see the damage, there will be tell-tale signs of mice living in your car. Such signs are: 

  • Foul smells 
  • Strange noises in various parts of the car
  • Mouse droppings
  • Chew marks 
  • Footprints 
  • Flashing check lights due to chewed wires

90% of the time, mice will live in warm, dark areas such as the dashboard, vents, and air filters. 

So, What To Do?

You will need:

  • Needle-nosed pliers
  • Screwdriver 
  • Vacuum 
  • Metal mesh 
  • Gloves 

Step 1. Open The Air Intake Cover  

To do this, you’ll need to gain access to the hood. Then, find the air intake cover below the windshield. It’s either attached with screws or plastic clips. You’ll need to use the needle-nosed pliers and screwdriver to remove the cover. 

Step 2. Vacuum Blower Housing 

After the cover is out, you’ll gain access to the nest in the blower fan. At this point, you’ll want to clean out the blower fan by getting rid of the nest and debris. Use gloved hands to remove the nest. And then vacuum out the water drain hose and ventilation system

Step 3. Block Mice Entry 

You may have cleaned out the mouse nest. But mice may still come back. To prevent reoccurrence, cover the entrance with wire mesh. 

Attach the wire mesh with cotter pins. If you can’t fasten the mesh with pins, you may have to drill some holes to attach it permanently. 

Step 4. Put Back the Cover

After you’ve successfully attached the mesh, it’s time to get everything back as it was. And that’s it. See, you don’t need an expert to get rid of mice from a car’s vents.

How To Get Rid of Mice in Car Engines?

The car engine is the first place that mice want to nest. But it’s the last place you want to find them owing to the engine’s vital components. Most engines now come with a plastic cover for the motor. It’s usually a nice place for mice to hide after they manage to get into the engine compartment. 

Other good locations are the plates below the engine. And if your vehicle has a filter in the top plastic cover, it’s the perfect hiding place for mice. 

What to do?

Step 1. Disconnect the Battery 

This will protect you from getting electrocuted or burned. After disconnecting the battery, let it cool down for a while. 

Step 2. Remove The Nesting Material

Get rid of the mice’s nest. Of course, with gloved hands and a face mask. 

Step 3. Disinfect the Engine Compartment.

Urine and mice droppings carry the Hantavirus, which can infect humans when inhaled. Use a mixture of household bleach and water and spray it on the compartment. Let the mixture sit for five minutes. Then, wipe the areas with a paper towel. 

Step 4. Wipe it Down 

Now, sponge the areas with the bleach solution. Then, dispose of all cleaning materials in a tightly sealed plastic bag. And wash your hands thoroughly with soap and water.

How To Prevent Mice from Car?

It helps to prevent mice from accessing the vehicle instead of dealing with an infestation. These are some ways to prevent mice in cars. 

Use Peppermint Oil 

Majestic Pure Peppermint Essential Oil

Rodents hate peppermint. All you need is 20 drops of the stuff in a spray bottle. Then, spray the oil on the engine compartment and other entry points. On the engine, do stay away from the mass airflow sensor since it is susceptible to moisture. Also, don’t spray the heat shield since oil will make it superheated. 

Use peppermint every six months as a mice deterrent.

Mouse Traps

Traps or glue boards are quick and effective methods of preventing mice in the car. Place the traps near entry points like to the wheels and on the floor. The traps will capture mice and keep them from invading your vehicle. 

Clean the Cabin

Do your kids eat in the back seat? Well, mice will be attracted to the leftovers. Food, debris, and unnecessary clutter attract mice. The material is ideal for mice nesting. To this end, you will want to maintain a clean car at all times. 

Park Away from Mice Attractions 

Trash cans, piles of wood, and shrubs are some of the places where vermin tend to hide. If you park next to these places, your car’s warm engine will soon become home to rodents. Avoid such areas, hence limit the chances of a mice infestation. 

Block Entryways 

Install metal mesh in areas where you think the mice may be accessing the car. Don’t use anything that could block air intake to the engine, like cloth. Look for black mesh or paint it black to make it invisible next to the other components. 

Park in Well-Lit Areas 

Rodents hate brightly lit areas. Parking in a well-lit area will prevent mice from coming close to your car.

Switch Parking Spot from Time to Time 

Whether you use the car every day or it’s been sitting in parking, make a point of changing the spot often. It will ensure that rats won’t establish a permanent location for a new home. 


Mice are attracted to cars because they offer warmth, shelter, and food. Plus, they will keep coming back if you do nothing about it. In this how to get rid of mice in cars guide, you no longer have to deal with mice. We hope our top tips will help you eliminate mice for good.  

Don’t wait until you have to fix an expensive component.
