How do the mice keep getting in?

I covered the cabin filter in chicken wire and that kept the nests out. I keep finding acorns inside the car and finally put a snap trap on the floor. Caught three so far. How the hell do they keep getting in? I�m at a compete loss.

Does the car have any cheesy mods?

At least you didn't find empty snail shells because that's a sign of rats.

Check all the rubber grommet wire pass throughs. If any are missing, a mouse can definitely get through the space around wire harnesses�

A big, mean cat will help!

There's a dead mouse carcass near bank 2's motor mount in my car. It's still there because I don't have the heart to remove him (her?). RIP

happy to give it some company. Found another one this morning. Major search effort planned for the weekend to find ingress point. Grr

I've also found that birds like to sh*t on my car

I have probably a dozen snap traps, each baited with a peanut, all around my garage every winter. I catch a half dozen or so when the weather turns cold. In the warm months, I get snakes in the garage, which take care of the mice.

Mice are coming into the garage under the door or almost any small opening. Your best chance at catching them is to place a yellow paddle trap without bait right up against any or all your walls as shown here closest to any doors. The mice want to stay along the edge and the paddle is wide enough so that any part of the mouse touching it can set it off. Don't use the traps with the little bait bar, there isn't enough surface area. I catch mice in these traps in my garage when the weather gets cold, and not one has made it into my cars. I use the same trap over and over again. Image below.

That�s exactly the trap I have in the car. I�m a little reluctant to set them in the garage since it seems a little unfair. There are always mice scurrying in my detached garage. Inside the car, sorry all bets are off. On the bright side, they seem to be one at a time. Haven�t needed to rebait it yet. PSA - nutella works great. Second choice is the mushy stuff in a 3 musketeers bar. One candy bar lasts all season.

This fixed the cabin filter. Still spiky and pristine https://rennlist.com/forums/newreply...ply&p=16602963

you are nuts. kill them all. little f�ers (big f�ers for me�rats) have caused me $1000�s in damage. bait traps, sticky traps, deterrent spray, sonic devices, and yes, even selective use of poison. next, i�m bringing in snakes.

I use sonic repellant. Cheap and effective. Not sure where you live, but there's no way I would be able to kill all the rodents who want to live in my garage and chew my tasty wires. Best to keep them away. https://www.homedepot.com/p/Bell-How...Q7ngQIflxpmsoA

I would do this in a second. Does it really work?

Quotes source post: 19114699

IIRR,,,rodents were responsible for killing 50% of Europe. Rodents carry virulent disease even nowadays, they spread it by crapping and pissing all over your stuff. imo, don't allow them to be anywhere near where you live.... Add in chewing critical wiring in cars/anything, and no denying they're pest.

I had a huge mouse issue in our last residence. Previous owners refused to kill anything and LOVED to feed the wildlife. They kept a full sized trunk full of bird seed in the garage and there was seed all over the place. The mice had a field day (not to mention the raccoons and other critters they feed in the back yard) !! Anyway, the first year in the house I purchased a few of those little white, enclosed snap traps and baited them with peanut butter. Over the course of less than a year I caught over 40 mice (yeah, 40+). I kept it going and over the second year I caught about 15. Next year I bought outdoor bait traps and got some "one bite" bait from DIY Pest Control. I placed them around the house, in addition to the indoor snap traps. I caught 3 mice inside and every single trap outside was empty by February. I then kept the inside traps the following year and had zero activity. I also kept the outdoor traps, eventually adding a few more of them and moving them out, in a "circle" around the house. Eventually, I had zero activity inside the house. I have done the same in our new home (in a very wooded area) and, in addition to the smaller "triangle type" bait stations, I added 3 large "commercial" sized bait stations to the mix. I put fresh bait in all of them when the weather starts to get colder. I collect them in the spring to clean them out and rebait when the next fall season rolls around. Over the last 4 years, all the traps have been either emptied, or had some moderate activity by the end of the cold season. The activity keeps dropping off year by year. I keep only 4-5 around the actual perimeter of the house. The rest are scattered around the yard and around my rather large shed. Zero rodent issues inside our home or shed (lots of equipment in there).

Little ba$tards. Chewing up my car. All bets are off. Cleaned it up and left some poison in the cowl for them. Hope this keeps them on the outside. Also explains how they got the acorns on there.

Works for me! Just replaced them this fall.

Where is this? I've got many rodents, but the mice are my main concern. Squirrels, mice, voles, rats, you name it. I have snap traps and glue traps, at first I caught something every day, but between the poison and the traps I'm getting them under control. Death too all rodents.

Just don't do the poison bait inside your car (or house for that matter). If they are living inside and the poison is inside, they will die inside and it will smell (and it will be tough to remove that smell). Use enclosed snap traps for inside, baited with Skippy and check often (every few days until it is under control, i.e; no activity for a few weeks). Use a very good bait for the OUTSIDE feeding stations. One bite types of bait are the best (and quickest acting), but slightly expensive. Although not as expensive as Porsche parts or repairs!!

I store my 996 in my garage and I lost my car cover to mice over the summer. I'm going to go with Sonic and the paddle traps. Wondering - what is the purpose of a car cover with indoor storage - dust? It doesn't prevent the mice from getting in. I think I'll save the $200 - $400 and wash the car in the spring

Indoor car covers only keep dust/sediments off the car - they don�t keep critters out. Poisons just aren�t a good idea (due to environmental concerns, pets, wildlife etc�) even though they do work - potential for collateral damage is too much. If your indoor space is susceptible to rodents/critters/vermin, consider an indoor Car Capsule�

Been using Bounce Fabric sheets on my C4S going on 20 non noshing rodent years

damage - it�s under the cowl in the center just above the battery. I put the poison on the battery tray for unlimited consumption. As others said, never in the house or vehicle interior.

They like peanut butter too.

Set four traps (yellow paddle Victors) a week ago and the score so far is: Me 2 - Mice 4. Killed 2 the first night and felt pretty good. Set out new replacement traps so as not to have any kill scent. I used vinyl gloves and peanut butter. Went back today and all four traps remain set but the peanut butter is gone!!! One of the mice must have sent a text alert to the gang. These things are soooo sensitive i can't imagine how the traps weren't tripped. Pretty smart bunch. I ventured over to the r/mice reddit and that group talks about mice - but as pets. ARGHHHHH.

Well, last week my C4S died a few houses from home. It was missing, sputtering, and would only kinda restart for a few seconds. I brought it to the shop, and the problem was...... out of gas! The little buggers had messed up something with the fuel level sensor wiring. My shop said they get one more 911s every month with rodent damage. The typical places they hang out are in the front battery area as in the pictures above, or over the engine below the intake manifold. The scary part is my Indy has turned down the repair work and sent me to the dealer. They said it can be very difficult to isolate the problems, and if one is fixed, then the next one surfaces, and they said the dealers won't sell them the wiring harnesses. Stamp out those little invaders, it is getting expensive, today these ultrasonic devices will arrive: https://www.amazon.com/dp/B004UOO2SI?psc=1&ref=ppx_yo2ov_dt_b_product_details https://www.amazon.com/dp/B004UOO2SI?psc=1&ref=ppx_yo2ov_dt_b_product_details .

Sorry to hear. Don't forget the Bounce dryer sheets in the frunk, passenger compartment and engine bay. They have worked for me for the last two winters.

I was doing some work at my rental unit and saw some mouse droppings. I also use Victor paddle traps and just for the hell of it, I checked their website for bait recommendations and saw this: 7 MOUSE TRAP MISTAKES YOU'RE MAKING Maybe #3 was your problem

I�ve killed 14 the past two weeks in my Basement and garage (one reason I store offsite in the winter). Seems to happen when the season changes. I use the plastic bait traps with peanut butter and also put grandpa Gus� menthol traps in the frunk, and spray under the wheel wells and front end with NHOU Oil on all my cars.

Inspect your garage seal for gaps as well as the sill plate. Gap the size of a dime they can get in. Check up high as well as low. Mice control begins with an exclusion plan. Chances are if you can see daylight, they have a way in.

sorry, missed this post. It�s under the cowl right above the battery. I subsequently sealed the hole and replaced the screen. So far so good.

You need to replace/repair that foam heater core cover, it will leak during heavy down-pours or car washes...I had a customer back in the day bring in his 911 ( under warranty) complaining that when he goes through the touchless car wash that foam would come from under that dash and land on his right foot, and this is exactly what I found was the cause....lol

Should not be anymore mice in there,that’s the “out” arrow🙄

One seldom has "a mouse". Much more likely that one has "mice". Just sayin'.

Quotes source post: 19156559

lol, well, I haven't popped open the champagne yet. I put out six traps and I'll leave the remaining five (no, I don't reuse 50 cent traps ) out for a few more days. The last time I saw droppings about six years ago it was in fact a mouse, not 'mice'. Hopefully that will be the case this time.

Sorry to revive an old thread, but I just wanted to say thanks to everyone who posted here—I actually stumbled across this discussion a few months back while trying to figure out how mice were getting into my 2002 996 C2. I park it in a detached garage, and despite traps and mothballs, they kept showing up… once even left shredded carpet insulation behind the battery. I ended up trying a few things, but what finally made a difference was a product called Box-Kat —it’s a kind of physical barrier you lay around your car. Sounds a bit gimmicky, but it actually worked. I’ve been using it for about six months now and (knock on wood) no signs of activity since. Figured I’d circle back here in case anyone else lands on this thread like I did. Appreciate the insights that pointed me in the right direction.

Thanks for the product referral. I use bounty dryer sheets in an attached garage and so far...

Yeah, tried the same for a while — spotty results, at best

Quotes source post: 19991420

FWIW - I also use snap traps and when I kill one, I leave it in the trap and let if decay. Mice communicate by smell and the decaying mouse is a deterrent...or so I hope.

Oh ... interesting thought. Makes sense

Quotes source post: 19991469

Actually the opposite. It'll attract them. They have no problem eating their own. It'll never end unless you find the spot they can get into and fill it with something they can't chew through. They chew pretty easily through the little rubber seals on the sides of the garage doors. I added some thin sheet metal there along the sides and filled in any gaps. It seemed to work this past winter.

I tried using the dryer sheets and the results were not so good. Maybe they loose strength faster than I thought, or I can't know if they are still working. My car detailer recommended bars of Irish Spring soap and that seems to work quite well. (But these are not scientific observations.) And the old standby, snap traps if I detect an new infestation in the garage -- which work really well, baited with parmesan cheese. Nice to see this subject resurface, spring is always the active time with mice around here.

I've used soap before too ... swear I found a bar with bite marks in it. That, peppermint oils, dryer sheets, etc. always feel likes they work until they don't. That's what I've liked about the Box-Kat. In theory, they can jump over it or they can't — so far it seems to have worked for me. Will say though ... important thing is to make sure they're all out before you trap em in!

Quotes source posts: 19991490, 19991469

This is exactly right. I re-use snap traps until they get really gross and I don't dare touch them anymore. And they keep on working.

I wonder if coyotes like the taste of mice?

Wonderful! I had a visitor at my offsite garage last night. I'm not worried about getting rid of this guy assuming he's planning on sticking around but it's going to be a challenge to close up the gaps on each side of the main garage door. I'm pretty sure he's eyeballing the cars and their wiring harnesses and thinking, "Mmmm...snacks all winter!". I ordered traps and steel screen from Amazon but as you can see by the light coming through the gaps in the main door, it's going to take all of my Macgyver skills to close them up.

All they need is a 1/4" opening to get in. Better to put away the faux engineering skill set and think about traps. I've used Bounce dryer sheets throughout the car, 0000 steel wool (exhaust pipes and air intake) and mouse traps in the garage for 4 winters and so far so good.

Smooth not cruntchy peanut butter in those traps...In 21 years of car ownership I can't give a number of confirmed kills for fear of The Hague

Another thing to think about is smell. Rodents have a sharp sense of smell and they can't stand certain odors. That's why the Bounce Sheets work fairly well. I use commercial ammonia in one of my sheds. I also have a friend that stores a car at a storage facility. At first there were a lot of rodents in and around the storage unit. The facility has traps out, but i don't think they monitor them. My friend used snap traps and peanut butter (Skippy Smooth), but he kept finding quite a few dead rodents, but also fresh dropping on a weekly basis. I told him about the ammonia thing and we put few bowls out, in each corner of the storage unit. So far, no more rodents, in several of the units. Apparently, they really don't like that smell. I am not a big fan either, but it it works............

Guys, let me give you 30+ years of experience - on aircraft (talk about crazy expensive with wiring chewed way inside of a wing, or a mouse dying in the wing on the aluminum spar - unrepairable - total scrap) I have had my aircraft in the same hangar now since 1988, with grass fields all around and plenty of mice. I have always used the green poison pellets or the green blocks and continue to do so. They certainly get consumed and reduce population, but the risk of one dying inside the wing is tremendous. For several years I used 18" high circles of aluminum flashing around each of the three landing gear. I do think it slowed down mice from entering the aircraft, but soon found evidence to the contrary, so I removed them. Obviously this method would not work for autos. Along with the green poison, I have used a number of regular traps and even sticky traps. They certainly work, but I do not access the hangar sometimes for several months. I have used dryer sheets (large interior volume though) and used many bars of Irish Spring soap. During the winter I found one bar that had been chewed on - not alot, but enough to know the little bastards made it inside along with droppings. My interior does smell very nice now! Here is the trick. I never would have believed it, I thought they were just scams, but I finally bought an ultrasonic unit since they had gotten much less expensive, It absolutely has worked! I only placed one unit where the sound projects at all three landing gear. Never a mouse problem inside again! I have used them for 4 or 5 years now. On my third unit now as they seem to fail after 2 years or so running 24/7. It is possible an electrical spike/lightening etc. made them fail. I am just not there often. I bought the Victor unit - Victor� PestChaser� PRO Ultrasonic Rodent Repeller Special Price $39.49 Model M792 One of the less expensive, not fancy - it just works! I confirm its effectiveness by having regular baited traps located by the three landing gear and a couple others in the sound radiating area in front of unit. NEVER a mouse. And I refresh the bait on traps every 6 months or so. Obviously I am very happy after many years of trying every wives tail, etc. I do not have any affiliation with Victor sales! I have added one in my two car garage that radiates under both cars for several years now and it seems to work perfectly, even though there is lots of evidence of critters in the rest of the garage.

Was thinking the same thing. I would wager he doesn't own a Pcar.

You lost

When we first moved into our current residence it had quite a mouse problem in the kitchen. We tried those ultrasonic devices. Found mouse droppings within inches of them. I'm glad they work for some applications, but they definitely do not work for all of them. My go-to is snap traps. That isn't going to be a cureall for everyone either. My ultimate solution was a new and well sealed garage. No critters can get in, period.

These cars have mouse gateways. I found mice coming in through the four corners: upper corners of the frunk and upper corners in engine compartment. Stuffed the holes with steel wool, so far so good.

My only experience with ultrasonic was a faux birdhouse that was supposed to limit the neighbor's dogs barking. It seemed like it might have helped for the first couple of nights but after that, it was back to normal. I set some snap traps and because I'm a sucker for gadgets, I bought one that is a rodent electric chair. It takes four AA batteries and kills them when they contact an internal plate. It's been 2 or 3 weeks and I haven't caught anything yet in any of the traps. I actually Googled how often rodents can go without water and apparently it's only a few days. Since that garage is drier than a dead dingo's donger, I'm hoping they decided it's not a good place for a permanent home. We'll see...

[QUOTE=2002C2;19113036]I covered the cabin filter in chicken wire and that kept the nests out. I keep finding acorns inside the car and finally put a snap trap on the floor. Caught three so far. How the hell do they keep getting in? I�m at a Get a 3 to 5 Oz. Med bottle put 6 to 8 cotton ***** in it and 20 or so drops of peppermint oil on them. Drill a few holes in the top and put it near the battery int the frunk. Works for me. Put one in the glove box too.

FWIW, the pest control guy who works on our rural property(chicken coop only) says changing mouse deterrents is the way to keep the mice out. We have cats that are loved more than humans, so poison other than in the coop is a no go. So, maybe a few weeks with one deterrent, then another, then a 3rd. ??

Funny thread.... That's just funny right there.... And FYI... mice are attracted to plastic wires in Porsches and other vehicles because the insulation is often made with plant-based materials like soy, which rodents find appealing to chew. They are also drawn to the warmth and shelter of a car's engine bay, and they must constantly chew to keep their teeth from growing too long. ​​​​​​​
