Dead mice in my new car!

Category Auto

I would really appreciate any help that you can give me. we just purchased a new (to us) minivan. We got it from a family that lived on a farm, and when we went to look at it and brought it home, the windows were down, so we really didn't think anything of the smell, as it wasn't that bad and we were on a farm.


Anyway, I went and got everything done at the title office yesterday, came home to transfer all the stuff from the old car into the van, and when I slid open the side door, I was hit in the face with a terrible, overwhelming stench! I found a dead mouse laying out in the open between the seats, but it appeared to have just died. I was just sick! anyway, I sprayed the van down with 2 bottles of febreeze, a can of airwick odor neutralizer, and some fragrance.

Got in this morning to take my son to school, and the smell is just as bad as ever! I tore up the carpeting in the back, and found a bunch of mouse poop, but I cannot find the dead mouse. I have no idea what to do. I don't know how to get rid of the odor??? and, i don't know if that would even be enough??? I mean, it's got to be some sort of health risk having that in there? Please help! I don't have any more ideas. Thanks.

I looked around the internet and haven't found much except that the body will cause odor until it is totally decomposed. With it being warm this time of year, hopefully that won't take too long.

1. Keep looking for the body. If you can find and remove it at least the smell won't continue to get worse. Look under the seats, possibly removing them if that is possible.

Treat the area around where you find it with borax, just dump a half a cupful or so on the spot. I've found borax is great for freshening and absorbing odors. You can mix it half and half with baking soda and sprinkle it around on the seats and carpets, then let sit for a half hour or so and vacuum out.


Fabreeze just covers the odor whereas both baking soda and borax will absorb so when you vacuum it up, it takes the odor with it.

2. If you can't find the body, keep the windows partially opened to let the odor out.

3. You might also try spraying with one of enzyme compounds used for pet accidents. See:

One site online had an odor absorber that might work for this.

Best of luck with this. I know it is a horrible smell but from what I've read, it isn't harmful to you, just smells bad and will go away once the body has decomposed.

I am also going through the same thing right now I've already found four dead ones but the smell is still terrible my husband is pulling my seats out today. But I did hear that the smell is very risky you should not be driving and it is very harmful and can actually kill you. The smell has been in my car now for about two days and I think it's starting to get a little better I cleaned it out with bleach and other stuff and it smells OK for a few hours and then the smell got bad again just waited out it will decompose sooner or later if you cannot find where it is good luck I feel yeah it's a terrible feeling

Dear Pryncess,

I feel your pain! A few weeks ago I began to notice a smell in my fairly new Honda sedan. I thought my car had picked up some smell from the garbage in the garage; sprayed it down with Febreeze for autos, but the smell got worse. Started looking around for some kind of food that got left somewhere in the car or trunk, found nothing. Aired out the car, searched more, sprayed more...finally found a small dead mouse near the radiator, but the stench continued. My stepson found another dead stinky mouse by reaching his arm way up under the air filter somewhere. Took car to car wash to get underside sprayed & sprayed water everywhere we could, but it was hopeless! Took car to dealer who said it was probably just a dead mouse in the blower & shouldn't be a problem. After almost 2 days of searching ($$$!!!), going through everything from the engine to the trunk, they pinpointed problem to the rear passenger side, BUT the nest or whatever is in the frame of the car & they can't get to it.


They could see mouse turds, pieces of dog food, and (yuck!!!) maggots by looking through the drain holes in the bottom of the door. They think I might have to take the car to a body shop to have the frame cut to get to the problem. Insurance agent not sure if this is covered; currently waiting for claims adjuster to look at car. I think this should fall under homeowners; want to make adjuster sit in car for 5 minutes...then I think he will pay!! Workers at dealership had to take frequent breaks because the stench was so bad. I'm a little skeptical of Susan's - "it will decompose soon" response. It's been 3 weeks since your post, the smell going away??? I'd love to hear the conclusion of your problem!!

How do you keep mice out of your car when it sits for awhile, we have a camp truck that sits for period of time, Mice seem to get into the car. Is there a way to keep them out ???

I had a mouse in my car and did not know it until it began to stink. I found a nest under the back seat of the car. I put on a rubber glove and dug the nest out and then put a small flexible piece of hosing on the vacuum cleaner and got as much out as I could. Then I sprayed area with odorcide which i get at Walmart and kept spraying under the seat and the smell went away.


this odorcide is also good for pet urine. I do have to tell you that after that i did get a another mouse. i live in the country. but after I pulled out the nest again and sprayed I didn't have any more problems.

I have a dead mouse in my car and I am still trying to find it. In the past I have found the dead mouse under the back seats. It can be hard to pop those seats out. In that instance, I smelled it most when I opened the trunk but not as much when opening the car doors. I has been convinced it was in the trunk. More recently, I smelled a dead mouse most when I put my head near the gas and brake pedals. It wasn't under the driver's seat.


Finally found two dead mice by pulling the carpet away from the dash near the gas pedal, and found the nest by pulling the carpet away from the dash on the opposite side. Usually the smell in the car disappears as soon as you get the dead mice out, but the smell is still there and I'm looking for ideas on where else to check. It does seem like one can get a clue for where it is by sniffing in various places around the car. The search continues!
