Wife brought her car in for no AC. I have checked cabin air filter and did not see any signs of mouse nest. Dealer said there were several inside the AC ducts. Unhappy wife.

Looking on Amazon for mice repellent for a car. Looks like various forms of peppermint oil and 12V ultrasonic repellers.

Nothing on Amazon looks like it has a super review.

Anyone found one that works.

I have a cat. He chooses not to go out a lot. But he is an indoor/outdoor cat.

I assume this vehicle is parked outside?

I've found that dryer sheets work fairly well, but they MUST be the strong smelling ones. The typical store brand ones are weaker and don't really do much.

Honda dealers sell a 60' roll of Caspian tape to ward off mice/rats. It's about $25 I think.

Where do they get in? I had a 400 dollar heater box/ blower motor repair for mice also on the rogue. Left car parked for 2 weeks and that was that .

If they are heading in thru the HVAC outlets, I would put screening on the rear heater outlets and the floor (footwell front outlets) Defrost vents ? IDK. Look for gaps in the HVAC air cowl inlet under the hood near the windshield base and epoxy screening there. From the engine bay, Look and see if there is knowing/chewing avident around where the AC refrigerant comes into the evap coil in the heater box.

A couple of months depending on heat, etc. I also use them in my power equipment with excellent results. Haven't had a mouse in an engine since, and I replace them every few months. I put them right on top of the blower screen on the engines. I also stuff one into an opening for the gear drive on snowblowers to keep them from making nests down there.

I had mice in the heater/AC ducts on my motorhome. Changed the worst hoses, sprayed AC duct cleaner https://www.amazon.com/gp/product/B000UHD74E/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 which neutralized any smells and now keep a 9 watt LED on a timer under the hood. No mice for a year.
Dryer sheets make nice nest material

I have a few of these around, in the garage and barn near the vehicles, and outside near the chicken coop. Keeps the population of all the rodents down. We also have cats, dogs, and chickens running around and none of them seem to eat the poisoned rodents that I have found. Or if they have, none of them have any noticeable effects.

Does anyone think the Glade scent things you attach for the air vent to blow at could attract mice?

One of my friends had a rodent get into their system, got there during a big camping road trip. They said that 200mi with a dead animal in the vents is not pleasant...

The garage they took it to said that they'd recommend switching the car to recirculate when parked, especially at a camp site.

Go to Walmart and buy a tube or two of "Capsaicin", it's cheap about $10. Take some of the mouses favorite food, cheese and coat some of it with the Capsaicin. Once they bite into it there should be quite a wild scene. I use this stuff for neuropathy of my clavicle and it burns like fire. I can't imagine getting it in your mouth. I'm sure the mice will find a new home. Wash your hands well after and don't get it in your eyes.

We had a 2010 Sequoia and bought some plants. There were mice in the pots and they got into the air ducts. I disassembled half the car and got rid of them but could not get rid of the smell. My wife made me get rid of the car.

I have replaced four air filters in my 06 Outlander and 09 Elantra Touring due to mice.

The Mitsubishi service manager at the dealership let me know their trick, and it has been working for me - unless I forget to re-apply.

Use mint scented air conditioner treatment. The dealership uses Ultrashield AC Odor Treatment in Spearmint. I have stuck with that, since it has kept the mice out, and it helped with the partially-desiccated mouse scent that tipped us off to the problem initially.

You can follow the directions on the can for doing the whole AC vent system scent treatment, but I would also put some blasts in the air-intake and air filter housing (cabin and engine) while the car is off. I now just do the latter, unless I end up with a nest due to forgetting to 'top up' my protection.

I have also used this to keep the mice out of my JD lawn tractor, since they like to deposit corn and other seeds in the battery housing and air filter housing there too.

No nests so far this year!

It might, they could confuse the scent with food.

What about drops of the peppermint oil onto the cabin air filter?

Could work.
I haven't tried it yet, so I cannot comment on its efficacy.

I still have a bit of spray left, but may try the essential oil on one of my cars as an experiment.
