To keep mice away from your RV, spread Bounce laundry sheets around the inside of your RV. I've done it for years and it works great.

I put bounce in my Rubbermaid boxes that I store clothes in out in the garage and it keeps everything out.

My mom has a severe problem with field mice getting into the heating/air fan housing in her car. No one else has had a problem when they visit her, but she has had to have her car in the shop at least 10 times for this in the two years that she has owned the car. The car is a Chrysler Sebring. Does anyone have any ideas on what she could use to stop them from coming in? She has outside pets and is afraid to put out any poison.

The moth balls do work. It was happening to me a couple of years ago. We took an old pair of panty hose and cut them up into several pieces. Tied the bottom end closed and put the moth balls in. Tied the top in closed and hung them in a few places around the motor. IT WORKED!! The only thing is, the smell is kind of strong at first if your using your heater or air conditioner. But, it saved me a lot of money in the long run.

There is not much you can do as it is the design that allows small animals to get in there, which is also why some others dno't have the problem. I work at a car dealership and asked a technician as I have never seen anything that you can do, and there is nothing you can do. Trust me, I have seen all sorts of things in cars, mice, nests, dog food, acorns, etc.

If you can stand the smell of moth balls in your car, I guess that would do it.

What about putting one of those ultrasonic things out near where the vehicle is parked, or is it too far away from the house or an electrical outlet?

He sprayed something around his yard, couldn't remember the name or what it was, but the strongest thing you could by without a license. I don't recommend that as I don't like chemicals like that.

One thing not mentioned above is this. I do hope no one is actually paying for the repairs. Your insurance covers it, I promise. I had a friend that had a squirrel who took up residence in the transmission of a Renault and when he turned the engine over in the spring (it was garaged during the winter), he heard the worst sound possible.

Ad

Ugh! I happened to be there for dinner that night and was working in an insurance claims office at the time. I told him to call his agent and sure enough, he was covered for squirrels! He thought he'd have a huge repair bill, but they paid for it. Just wanted you to know.

We. also had two cars damaged from mice. We were told that Irish Spring soap would keep the critters away. We put some in the engine where the electrical wires are and so far no further problems. Is it the soap or have we just been lucky, I don't know. We never asked a mechanic, so use at your own risk.

They make small traps called mice cubes where the mouse can get in but cannot get out. The traps can be baited with peanut butter and will have to be cleaned out daily; I realize this is not a good long term fix but it may catch a few that the moth malls don't catch?

My car broke down beyond repair and I could not afford to by another one at the moment, fortunately my parents had a car sitting in their yard that was in seemingly good condition and was only there for about a year

Ad



When I Begin cleaning it out I discovered that there had been several families of mice living in it! Fortunately they all seemed to have deserted the car, however they left behind several little presents for me to clean!

I got the car repaired (the things the mice had chewed through and I also needed a strut). The mechanic told me that not only were they living in the car (and trunk) they had also built a nest in the blowers (for the AC and heat).

So I cleaned out the car I shampooed the interior and vacuumed and sprayed almost a whole bottle of fabreeze all though out the car and the smell is still there! (although it is not as strong)

I personally hate mice and their smell makes me sick but I can't afford to buy another car for a little while so I don't know what to do. I would like to get every little bit of smell out of the car not only because it makes me sick but also it's really embarrassing (I could not imagine taking out a date or going somewhere with my friends and them having to smell mouse!)
Ad



So please, any tips or ideas would help. Everyday I drive to work in this thing and it makes me nauseous.

Get some OUT in the WalMart pet department .Pour it on some wads of paper towels & stick it everywhere the mouse smell seems to be invading from unless the towels could catch fire .
Fabric softener sheets would probably work wonders too.

I had a similar problem. Mice invaded my car (don't know how) and I used humane mouse traps to catch 2 mice!

Anyway, to clean the car, my brother kindly removed all seats, all the carpet and shampoed the lot!

While everything was out, we used disinfectant to clean the car and get rid of the smell, which worked. Mind you; you can only get the smell totally out if the carpets are removed, washed thoroughly and the surface below the carpet AND the underlay are disinfected! its not easy.

After 6 months of cleanliness.... the mice are BACK! I don't know what to do..

I had mice in my car while it was sitting at the farm over the winter, they have left now but they left me a hell of a mess to clean up. They got under my carpet in my hatchback where the spare tire was and had all sorts of food left behind (canola,dog food,cat food, etc.) I had to clean all of that out, then i wiped it down and used industrial cleaner on it and spray painted over it. Well after that at least every day or two the mouse smell would come out of nowhere, and would only stay for maybe 5 minutes. This was no good because if i had a date or a friend in the car they would get all grossed out and make fun of me for having the "stinky car". Well then i went into the spare tire area again and cleaned it out with Fantastik Orange, which took off some of the spray paint but also got alot more of the mouse droppings and little bit of gunk i had missed the first time. I wiped it down with a rag and the cleaner at least 3-4 times, then i spray painted over it and let it dry, then i sprayed some Febreeze over that and let it sit over night. Well it has been a week now and i haven't had to deal with the horrid stench even once. Hopefully this helps someone out with their mouse problems.

I bought a 2007 Jeep less than a year ago it wouldn't start. I had it towed from the dealership (not under warranty). They said mice had chewed wires and plastic to the tune of $1100. Before I purchased this car it was garaged for a few years.

Could this damage have been from it being garaged before I bought it? Could it have been driven by me for 8 months with no infestation on my end? Or would it have to be recent? I want to challenge the dealer, but don't want to have this sound totally ridiculous on my part. Any advice?

Your posted question is a little hard to figure out. Which of the following timelines is correct?

You bought a Jeep that had been garaged for a considerable length of time from a used car dealer.

The Jeep wouldn't start at the dealer so you had it towed from there to a garage where you were told there was $1100 worth of mousie nibble damage.

If the above is the correct timeline, did you sign an 'As Is' contract? If yes, you are out of luck-no court is going to give you damages based on that 'As Is' clause in your contract.

But if you didn't sign an 'As Is' contract, you probably DO have a case. Try talking to the dealer and politely point out that without satisfaction you will be taking the case to an attorney (or Small Claims, which is cheaper)

OR

You bought a Jeep that had been garaged for a considerable length of time from a used car dealer.

You drove the Jeep for eight months without any problems but then suddenly (after eight months of carefree driving) the Jeep wouldn't start. The mechanic you took it to found $1100 worth of mousie nibble damage.

If that is the correct timeline, you have no case with the dealer because you were able to drive the Jeep without problems for eight months. Refer to the contract (or bill of sale) to re-read the terms of the warranty (if any)-if a warranty was part of the sale contract it surely has expired, most used car warranties on a vehicle that old expire after 90 days.

If you were offered and then opted to pay for an extended warranty of one year, you still probably are out of luck because the damage is from mice-not a fault of the dealer because mice are a condition of where you 'garage' the vehicle when not being driven.

What you do have is a mousie invasion going on where ever it is that you park the Jeep when not driving it-you need to sort that because those little 'darlings' will simply re-nest in your engine box and repeat the damage.

When mice move into the inner workings of a vehicle they waste no time chewing-within a day you are going to have a problem.

The damage they do is considerable and that damage shows up immediately. This is not something that 'develops over time', this is a 'they moved in on Saturday night and by Sunday morning I couldn't start the car' thing.

If you 'garage' the Jeep at your home, this is your problem, sorry about that.

However, if you are renting a garage or parking space, you may be able to recover damages from the landlord. Check your rental agreement.

(Unfortunately, most landlords have a clause relieving them of any damages caused by pests. Re-read the contract to be sure of the terms)

I would ask to see the old parts before I believed them about this. In fact, ask to see all old parts, when they are removed, and you can explain that you like to keep photographs or a record of all parts you have to have replaced.

Iv'e use peppermint oil for many years in our camp, cars and home it works great and doesn't leave a terrible smell that mothballs do. It can be purchased at any health food store. Put a few drops on a cotton ball and place around areas where mice signs are visible; but you do have to refreshen the cotton ball every so often. Another idea is yo put the soaked cotton balls in a small container with holes poked on the lid.

One way to get rid of mice is to keep the garage tidy and clean. Try to not put clutter or any boxes on the floor of the garage. See if there are any holes in the garage that the mice may be coming from, if so I would repair or close the holes up.

I have mice in my brand new car! I first noticed them in my glove box, they ate ketchup packets, so I took everything out of there. I also put peppermint oil on a cotton ball. They still go in my car. NOW they are all over, on the seats, on the dash, steering wheel. It is like they have set up camp, yet I have never seen them, just the droppings!

We park the car in the garage (which is infested with mice this time of year) and I was wondering if anyone has ever had this problem. My car is starting to smell! I use urine spray that I got for my dog who pees on the floor, it works well, but every morning they leave more. I set traps and they are constantly full. Is there a hole I can plug up or something! AHHHH!

Well, I am not sure how to do this, but one thing you DO NOT want to do is put mothballs in there. Mothballs are often given as a solution for keeping rodents out of places, but the stench from them is sickening, and very difficult to irradiate. Besides, they are poisonous to people as well as to all animals and the moths they are supposed to get rid of.

My remedy for getting rid of mice is always a cat, or several.

It would appear to me that the mice nested in the ducting either between the air intake and the heater core or between the heater core and the ducts under the hood. Check this hose under the hood for holes first. In either event first disconnect the intake air hose where it connects to the heater core and clear any debris. This is most likely the location of the blockage.

Determine how the mice got in and determine how to prevent the entry in the future. I do not advise blocking the hose but some hardware cloth (mesh wire with 1/4 or so openings) from a hard ware store of feed and seed. Most feed and seed stores sell buy the foot.

Mice Nesting In My Car

Lisa, the mice being in the car isn't the problem, it's where you are parking it. If it's in a garage, you need to treat the garage. If its outside, look for a nearby wood pile or brush. I also live in WI. I do not kill outdoor mice, but move or dismantle their nests and remove anything they can use for nesting material. Mice provide a necessary part of the chain of life we depend on. Don't worry, they won't come running back like little lost sheep. Poisons provided to kill them will also kill toads, frogs, and other little critters you need outdoors to help control insect populations. (05/26/2005)

I also have mice in my car. This is the second time. They have eaten all the wires causing my transmission to go out and the gas gauge not to work and the traction control not to work. It is costing me a fortune. After the first time it took me a long time to be able to drive my car without freaking out. I put peppermint oil and Bounce inside the car and I bought some fox urine to sprinkle outside. That worked. Then I sort of quit doing it because I thought the problem was solved, not, they are back. It is disgusting. But I do know that fox urine works. (01/02/2007)

Just a note for the people with mice in their cars. If you park your car in the garage and store dog food in the garage also, the dog food attracts the mice. Once they are in the garage, the nice warm engine does the rest. Food and a warm place to sleep. Isn't that what we all want. Get rid of the dog food or put it in an air tight container and remove all spills. (06/05/2007)

Just trapped a mouse in my new Toyota Matrix using an old fashioned spring trap (with extra old cheddar). Other approaches did not work. She was cleaning out tissue in the car and building a nest in the airbox. Turning on the AC each morning would create a wedding effect.

I don't know how it entered, but I am now parking the car away from a wood pile where I suspect there is a large colony. I would have preferred a more humane method, but I am worried about the airborne disease possibility.

Mice Nesting In My Car

I tried peppermint essential oil on cotton balls and the mice just play with them. I have 2 mice (I think) that are too smart to be caught. They run "around" traps of any kind and they boldly "play" in the kitchen. These are baby field mice, not rats or anything, just smart mice.

Back to peppermint, they seem to actually either like it, or they're attacking the cotton ball. It doesn't deter a thing, matter of fact, it gives them something to play with. The only thing that has worked for me is trapping. I keep the house very clean and when they get super hungry I lure them across the counter with peanut butter cookie crumbs to fall off the edge into an empty trash pail. I have caught 2 this way and another with a chocolate donut.

Sticky traps are okay. You can help them get off them with baby oil once you have caught them. Just remember to let them go in a place they can find food or they will find their way home. Also, mice follow the scent of their droppings. If you can do your best to remove droppings regularly, they get lost. (10/20/2007)

Mice Nesting In My Car

I've been dealing with these rodents for years now. They are a pain. I disagree with the post by c.j cox. There is no being nice when it comes to these things. I live in the country and have to deal with them as soon as it becomes cold out. The only way I have found to get rid of them is to set out traps. Get two pieces of cardboard that you can reuse throughout the winter. Cut them big enough to fit on your floor. Put two in a couple nights a week or more if you see droppings.

You do not want to poison them. They will go back to their nests and die in some remote spot in your car. Be proactive. Don't be lazy and wait until it's months into winter. They will come back every single year. My next idea is the mice alarms they have. The sound that drives them away. I haven't found one built for a car yet. That's probably going to be the best invention yet. I thought about buying a house one and plugging it in and shutting the door on the cord. I might try that. If it works I will post again. However, using old school traps I have been able to keep my cars smelling normal and to prevent any big nests from being formed. (12/09/2009)
