How to keep mice out of my car

Mice will take up residence in your car for the same reasons that they will make their way into your home. They are seeking a warm, dark place to stay safe from predators and the elements. They are also seeking easily accessible food sources.

Mice will tend to forage for food close to their nests. They will typically only venture out about 25 to 35 feet in search of a meal. So if they are setting up shop in one of your vehicle’s it’s likely that there is a food source close by.

Mice Get Into Your Car Through:

Here are some basic steps to take to prevent mice from thinking your car is a good place to hang out:

  • Remove any food from your car.
  • Do not park your car in tall grass or wooded areas.
  • Open the hood of the vehicle.
  • Place traps inside your vehicle.
  • Place a sound repellent device near your car.
  • Put deterring material in your car (dog hair, peppermint oil, cedarwood, etc.)

Some of these are self-explanatory, such as leaving food in your car and parking it near locations that mice and other rodents live.

Opening the hood of your car will eliminate the warm and dark feeling of the engine compartment. This will deter mice and any other mammals that are seeking shelter to nest under the hood.

I have mice in my car engine: How to keep them out?

The engine compartment of your car can be an inviting place for mice and other rodents. It is typically dark and relatively warm with plenty of small crevices for them to come and go. To keep mice out, you need to make it less desirable for them to be there in the first place.

The goal is to make your car uninviting to mice.

How often you actually use your vehicle will be a big factor in keeping mice out. Try to use the vehicle regularly or at least start it up on occasion. Mice are looking for a predator-free environment, so if you are in the vehicle often they will choose not to be.

Letting light into the engine is another easy first step. If you are able to, keep the hood up when you are not using the vehicle. Flooding the engine compartment with light will deter mice from finding a warm and inviting location.

Where possible, you can also block mice size entries into the engine block. Wire screen works very well when placed over these openings. You can also try placing traps on the tires or wheels. Mice will use these to climb up from the ground to enter your vehicle. Other common entry points include vents, opening near cables, openings near the foot pedals and the steering columns.

Park your vehicle in a location that is not convenient for the mice.

Your parking location should:

  • Park your car in a garage or other shelter if possible.
  • Keep the area around your car clean.
  • Not store food or trash near the vehicle.
  • Be away from tall grass, vines or shrubbery.
  • Have gravel or pavement underneath the vehicle.
  • Be away from wooded areas and other mice habitats.

One last thing to consider is the use of deterring smells. There are a number of human-friendly options available that will make your car engine a less desirable residence for mice.
