Here is a update on this problem.
I bought a 2006 prius and decided to add the mouse guard screen.
I took lots of pictures.

I had to remove the wiper blade arms so I could uncover the spot where I wanted to add the mouse screen.

removing the wipers is very difficult, you need a small pully puller.
with the correct tool it is not bad.
I will post pictures below

While I had the car this far apart I decided to remove the drivers side and see if there is another opening that needs to be screened.

Hobbit commented that he thought that there are other openings and I have to say he is right. the other side also has openings that need to be screened.

I will post pictures below.

Any openings under the car?
I didn't see any other openings for the fresh air intake and it's a good thing because I was running out of screen.

I can't believe that toyota could build such a great car and not do this simple screen on fresh air intake.

small animals nesting in the fresh air intake is a real common problem.

Even hyundai has addressed this problem on their 2001- present cars!

WATCH OUT TOYOTA, HYUNDAI IS GOING TO OUT SMART YOU !!

:cry: My Prius was towed to the dealer...apparently those little rodents love my car. This happened in the winter, but I thought they would be gone by summer. Not a chance..I have tried mothballs, but I smell them in the car, putting used kitty litter aound the car, mouse traps along the driveway and house....I am at my wits end. I was told I should report it to my Ins co. This is getting out of control.....

Mothballs are hazardous to people health, and are bad if you have cats or dogs that might ride in the car, or be near where the car is.

I think I'd skip the moth balls.
I was told to use 'FRESH CAB" - so far so good..no mothball smells..in fact this smells really nice.

Looking back at the first post on page 1 by SYNCMASTER, wouldn't it be simpler to just plug the hole labeled "Entrance to the mouse hotel" rather than pulling off that black cover and putting in all those screen covers? Or can (and will) mice squeeze between those vertical slats. Any additional thoughts on this topic would be appreciated.

Hi, Bruce,

That opening (& its mate on the opposite end) that you think would help to plug is clearance for the hood hinge to move. Plus the plastic piece doesn't go all the way to the sheet metal of the fenders & mice can certainly squeeze between the fenders & the ends of the plastic (let alone if you were able to plug the hinge clearance area).

Despite getting my hands cut from handling that Gutter Guard material (that can be found in your neighborhood hardware store for a couple of bucks) after you cut it to shape to cover the 5 holes [yes, FIVE (2 behind the plastic pop-out cover & 3 over on the driver's side that you can't see until you remove the whole plastic tray/cover), the satisfaction is well worth it knowing that mice can no longer get into my car.

Even if you cover those 5 holes, you still need to be somewhat concerned that your mouse problem may not be entirely cured. I didn't review all 4 pages here, but if it isn't in this thread, then you can do some additional searching to find other similar threads (sometimes listed at the bottom after the very last post in a thread---Edit : they do that over at PriusChat, not here though) where others have found another possible entry point in the hatch area. Behind the plastic panels on each side there is a hole in the fender covered by a little rubber flap that the mice have no problem moving aside to get in.

Those should really be screened off too with the Gutter Guard material, but I haven't done mine & so far I haven't experienced any mouse problem. I think the front is more inviting because the engine compartment is warmer than the rear fender area & while they are keeping cozy under the hood they begin to explore & sense the heated air from the cabin escaping through those 5 big holes in the firewall. Some have found nesting materials & food & droppings inside the airbox & have screened off the tube at the entrance to the airbox, but if they take that stuff into the tube in the first place, they can fill up the whole tube if you only screen off at the box. So I screened off the end of the air intake tube by the windshield washer bottle so they can't even begin to get in there.

Even if you screen off the front 5 holes & the air intake tube & don't do the 2 rear ones, you still have one last concern that may involve very expensive damage, and that would be the mice chewing into your wiring harnesses under the hood. Some of those harnesses will cost about $1,000 to replace. That's why some have been suggesting mothballs or cotton balls soaked in peppermint oil to ward them off.

Another edit : By the way, Bruce, where have you been for the last 3 years? Are you just starting to have a mouse problem too & that's why you are re-visiting now? Glad to have you here at any rate.

Sounds like an absolute nightmare... Call an exterminator!

We have had a horrible time this year with mice in our 2000 Sienna. Been to the dealer twice for disassembly and detailing. Now another mouse is in thereLas Vegas hotel roomsI guess I'll have to take a day off and watch the dealer disassemble it, stop them at the right moment, and install some screen.

We asked them to install some kind of screen last time, but it appears that if they do not have a Toyota part number for it, they will not do it.

I was going through my browser bookmarks and there was priusonline.com...my God, it's probably been four years since I posted here. And it's funny that I'm actually a moderator here. Shortly after I purchased my 2005 Prius, I found this site and must have posted at least 200 times. Anyway, hi Ct. Ken V and any other holdovers from the early days.

My Prius is going strong here in Vermont with 130,000. It's had almost nothing but routine maintenance, though I've been told the water pump and an axle seal are starting to leak and will need replacing in a few thousand miles. I appreciate getting 53 MPG in the summer and 46 MPG in the winter (with studded snow tires).

As to the subject at hand, my Prius has suffered the wrath of mice on and off (but mostly on) since it was six months old. There were signs of them or they would make nests in the air filter housing, cabin filter (that was the worst spot) and in the spare tire well, and I'm sure other places I can't access. I tried several solutions including dryer sheets and peppermint essential oil in the cabin filter, but it wasn't until last September that I decided to place a trap under the hood. I did it almost every night for a month or so. I trapped about four mice doing that and for the first winter there's been no sign of mice in the car - cabin filter totally clean and no smells. They must have gone elsewhere like the woodpile in the new woodshed (there was a nest there) and hibernated. The car smell has disappeared, though it may come back in the warm humid weather.

So that's it for now...

Hi, wayneswhirld,

It's great to see you back. There's only a few of us old-timers still here (me, firepa63, & Phoenix basically). Most everybody left when the spam got so bad about 2 years ago. I kept sending PM's to Jeff (one of the 2 original owners) about it because all of the moderators were gone. Next thing I know, he made me a moderator without my knowledge. So when I discovered those powers about a year & 1/2 ago, I started deleting all the spam & have to keep up with it each day. Up to this point I've deleted/banned about 6,000 spammer's accounts & IP addresses (sure could have used your help back then).

This place isn't as active as it once was, but please do stop in again (& often) & contribute your knowledge as you used to, & give yourself some more credit because your post count now stands at 637. I was really happy to see an old friend back again tonight. Thanks for stopping by !!

(By the way, I now have 125,000 miles on my 2005, so you have 5,000 more miles than I do, but I've only got 40 more posts than you do.)

Using peppermint oil on cotton swabs helps but after months of no activity someone is back. But that forgotten candy cane was the lure as well as the cold temps. Will check hotel entrances and try to plug up for sure.

Thanks for the advice on screening. I also had the mice nesting in the insulated cover on the bottom side of the hood. I removed this cover to find the resident still at home.

Hi, I'm new to this forum. Can you provide a little more detail as to where the 5 holes are? I had a 2001 Prius and it had a mouse problem. I now have a 2012 Prius and it too has a mouse problem.

Like most people on this forum (and others) , they are nesting in the cabin filter.

I blocked the vents in the hatch with hardware cloth. They are still getting in.
Are the 5 holes accessible from inside the cabin? Under the hood?

I would appreciate any help you could offer.
