I found a package of toliet paper, and a paper bag chewed up and mice crap all over my back seat 3 days ago. I stripped everything out of my car , disinfected the inside, vacuumed. 2 nights later he is back. I drive my car many many times a day. How and where is he survivng. what can i do besides traps because he is ignoring the traps..

They ride around with you--and sleep all day, party all night.

You'll have to take everything out of the trunk down to the bare metal, also pull the rear seat bottom. They get in and find all sorts of hidey-holes. Use a vacuum cleaner and clean out your car.

Look for broken rubber flaps on the air vent, that's where they will come in. Use duct tape to cover the vent if necessary. Typically in the truck behind the wheel well area:

Had a similiar problem at one time. No baits or traps worked. I set up a trail cam and observed it bypassing everything. It was only interested in stealing foam from a seat cushion. I think it was a pet mouse that some people next door released when they moved and not a regular wild mouse. It was gaining access to the interior via the hole for the cabin air filter under the cowl. I mounted wire mesh over the hole, screwed in with self tapping screws. No more mouse problems after that.

I do 2 things.

1. I use peppermint oil mixed with water and spray it in my engine bay and cowl.
2. I lay this trap inside my garage and they work well. I use peanut butter as bait. I do not touch the box or trap with my bare hands even new, gloves is your friend) I don't want them to smell my hand or oil from my hand). I have caught so many in during winter times.

3. Some use paper glue traps, not humane but it does the job too.

I wish you luck, a co-worker of mine just had his 2016 car totaled due to a $15k bill in wiring harness damage.

FIrst thing is do not leave food or crumbs or food wrappers in the car. I'm always amazed at how dirty some people's cars are with food and wrappers strewn all over the place including under the seats. Second is to try and block off any opening 1/4 inch or larger where they might be getting in. One very common place they gain access to the cabin is the cabin air circulation motor intake in the engine firewall. There is a fairly large opening for the cabin air circulation motor intake that doesn't typically have a screen on it.

See my post at the following link for some examples pictures of that engine firewall opening for the cabin air circulation motor on a 05 Corolla. And what I did to deal with it.

In my case they were getting into the cabin air filter and chewing it up and they were getting into the engine air filter and chewing that up as well. I duct taped some window screen mesh over the openings and so far seems to have stopped the mice infiltration.

One can try all the usual methods if a mouse is already nesting inside the cabin. Bunch of snap traps or similar baited with peanut butter, peppermint oil on cotton balls scattered in the car, dryer sheets, Irish spring soap bar shavings, etc. But none of those methods work unless one also cleans out the car and blocks off common cabin entrances. If the vehicle is parked in a garage also put down traps under and around the car in the garage to catch any living in the garage itself.

And finally use the forum search feature, LOTS of past discussion of mice in vehicles being discussed here with various ways to try and deal with it.

Several thoughts:

1. If it ignores traps baited with cheese, it may be a field mouse. Use peanut butter to bait the traps and it won't be able to resist!

2. A couple moth balls in the trunk area will deter it from staying there. However the smell may deter you from driving it. Fortunately it will dissipate over time.

3. If all else fails, ask a friend or neighbor for some shedded cat hair. Distribute the hair throughout the trunk area to deter the mouse.

I'd keep it simple, put peppermint oil as others said (usually comes with an eye dropper) around each of the tires, they have to climb up from somewhere. I've also put ant poison around the tires, its smells nasty to us and them.

If things persist and you have a power outlet these work for sure: (I use them in a hunting trailer, no mouse poop anywhere inside and its left alone for months at a time):


Luck.

I had a mouse that chewed through my cabin air filter, to gain access to the rest of my car. I was parked for a long time in winter, so keeping warm and cozy was its motive. I solved the problem by replacing the filter and for some reason the problem did not recur. It could be that by the time I discovered the problem, I had driven to another part of the country and the mouse's routine was ended.

Check your cabin air filter for chewing damage.
