Can Rodents or Mice Ruin a Car?
Can Rodents Ruin Cars?
The simple answer to this question is YES!!! Is there a way to prevent this from happening? Absolutely!!! Every minute of the day there is a mechanic uncovering damage caused by:
and other rodents that chew wires, hoses, plastic panels, and other car parts that make good nesting materials. Not only do they damage cars by chewing parts, but they also ruin cars by urinating and defecating throughout the entire interior which doesn’t leave a pleasant smell; in fact it's downright raunchy.

Signs That Mice May Be Living in Your Car
Rodents are not very clean nor do they pick up after themselves. If you think you may have rodents, like mice, living in your car you’ll need to look for evidence, like mouse droppings, bad odors, or weird sounds. One of the most common noises you’ll hear is the heater fan making a rumbling or vibrating noise; this is because mice like to build nests in warm dark areas and the heater blower motor meets both criteria.
The heater blower motor may provide these comfy living conditions but it also comes with a little surprise. Once the operator enters the vehicle and turns on the fan, the amusement park ride begins for these little critters; some make it out before the ride gets out of control, some don’t, and if they don’t make it out in time, all hell breaks loose and so do their little bodies. I’m not going to go into details because I’m sure you can imagine the mess it makes, and the smell that follows a few days later.
Rodents Give Mechanics a Bad Name
There is a disconnect between the customer and the mechanic when rodents are the cause of a problem in a vehicle. It’s almost like the customer doesn't believe rodents could be living in their vehicle and they think the mechanic is selling them a bunch of malarky. BUT there are many news reports on this very widespread problem and tons of documentation on the issue.
Some of the most common problems found in our Honda shop are chewed windshield washer hoses and nests built in the HVAC blower motor. I’m not sure what the attraction is with these windshield washer hoses; maybe it's because they have alcohol running through them and it makes a nice night cap for the mice? In our garage, we see about ten of these chewed windshield washer hose problems each week and a half dozen HVAC heater motor nests. Some of these cars are in our inventory and the others are customer vehicles.
What Rodents Chew In Your Car
So you’re probably asking yourself, “Self … where do the mice get the nesting material from?” Most of the material comes from either your vehicle or your garage. Items they use from your vehicle include:
- Insulation they chew from the vehicle's hood liner (where the windshield washer hoses are located )
- Carpet insulation
- Interior upholstery
Mice also like to bring in snacks for the late-night matinee, like acorns, dog food, bird seed, and French fries found under the seats. They taste great washed down with a little windshield washer fluid. Remember, they have unlimited access to your vehicle, so it important to keep your car clean with no snacks left behind for your unwelcome guest late night binge eating problem. One important thing to remember about rodents is they shit and piss where they eat and live and that’s not cool.

When Rodents Live in Your Garage
If you park in a garage, there is a good possibility that these critters will have a smorgasbord of options. If you’re anything like me, I store water, dog food, birdseed, snacks, and leftovers in the garage. It's only because I'm lucky that I don’t have rodents living in my garage or vehicle.
If you think you may have mice or rodents living in your garage, you can either set up snap traps to put a permanent end to a temporary problem or you can get an electronic rodent deterrent system that simply plugs into a wall outlet. I have also found battery operated units that you can place inside your vehicle.
So what can you do to help prevent further damage or evict these critters from your car? You can try one of the many electronic devices mentioned above or you can try a different line of defense like peppermint oil or Pine-Sol. I have also heard of customers using Bounce dryer sheets. I’m not sure dryer sheets work but your car will definitely smell better.
Stop Rodents From Chewing Wires and Hoses
If you have rodents that are chewing wires or windshield washer hoses, there’s a rodent tape that can be wrapped around these areas. The tape has hot pepper embedded in the tape and most rodents don’t like to eat hot pepper, unless it’s on the hot fries under the seat. If you’re looking for a spray, there are some commercially offered sprays you can spray directly on the affected areas.
