A scratching sound in the dashboard, a strange smell in the interior – sometimes everything points to an uninvited guest: a mouse. Especially in autumn and winter, the small rodents like to look for a warm place and make themselves comfortable in the engine compartment or even in the vehicle interior. A “mouse nest” in the car is not only annoying, but can also lead to damage and safety risks.
Why are cars so attractive to mice?
Mice love warm, dry and protected places – and what could be better than a parked car? The engine compartment with its many cables and hoses offers ideal nesting opportunities. In addition, cars are often parked in garages or carports, which offer additional protection from predators.

What damage can mice cause?
A mouse nest in the car is not just an aesthetic problem. The rodents gnaw on cables, hoses and insulation material to get nesting material. This can lead to short circuits, malfunctions and, in the worst case, even a fire.
“Mice can cause incredible damage,” warns Dr. Ing. Klaus Müller, automotive expert and author of the book “Modern Vehicle Technology“. “A chewed cable harness can quickly cause several hundred euros in repair costs.”
How do I recognize a mouse infestation in the car?
There are some signs that may indicate a mouse infestation:
- Rodent tracks: Droppings, urine or food remains in the car
- Bite marks: Damaged cables, hoses or insulation material
- Nesting material: Crumpled paper, leaves or fabric scraps
- Smell: A sweetish, pungent odor
What to do about mice in the car?
Prevention is better than cure:
- Cleanliness: Regularly clean the car, especially the footwell and the trunk.
- Remove food scraps: Food scraps and drinks in the car attract mice.
- Parking space selection: If possible, park the car in a garage.
- Ultrasonic devices: Ultrasonic devices can deter mice.
