How to keep mice out of engine

Hello all
Just want to see if anyone has any good ideas how to keep mice out of my motorhome engine. Probably very hard to do but any ideas would be great. Thanks.

When we lived on an acreage we used to leave the engine hood open when stored off season. The theory being that mice do not like to be exposed.

We store our vehicles in our barn , so the chance of mice is a sure thing.

I have been using Dryer Softener Sheets for years with great success.

I put them under the hoods of our MH , MG and boat . I scatter them in the cabinets and on the floors and in the trunks. I put them on the ground around the tires.

Since finding a nest under the MG hood , the sheets have stopped any further infestation.

Works for us .

There really is no good way to keep mice at bay unless you can park in a well sealed garage. A hungry cat helps.



There are many threads about this and I have yet to see a real solution. I have just spent an hour today after several previous hours under what I thought was our sealed 5th wheel - and still can't find a mouse doorway.

Everything I've read on the issue has been debunked from dryer sheets to mothballs to electronic ear zappers that only mice can hear. The next thing I plan to try is wolfsbane! Hey if it works on Ware wolfs it should work on mice right?

You will find that the mice will love your dryer sheets to make new nests. Chuck

I was pulling my engine cover off not so long ago and felt something like needles scratch the back of my hand. I pretty much tried to do a backflip but it was just a flop. Got a very different grip on the cover and took it off. About four feet of black snake curled up on the driver's exhaust manifold. Since I wanted to work on the engine and there weren't even any scratches on my hand I encouraged him to go elsewhere. Last saw him headed for the garage where I keep my old cars (that I also don't want mice in). Haven't found a mouse in a trap all summer. I don't care for snakes at all but in stored vehicles I consider them very much the lesser of two evils.

I don't like poison as things have a nasty to crawl off into a dark corner and die somewhere where I can't find them even though they stink to high heaven.

I use Downy dryer sheets.

I replace them every month , and after 5 years of winters have not had another nest or sign ( droppings ) in any rig .

I have found sign of them on the work bench and open shelves , so I know they are still around .

Whether other brands of sheets work , I wouldn't know as Downy is the only brand I've used .

I found what looked like a mouse nest made of battery insulation and some small mice feces in my Ram pickup a couple years ago, and used a product called all natural Rodent Defense Spray. It gets a lot of bad reviews, and some good ones, but since I started using it I haven't had any mice return. It has a strong minty smell, but when I use it it doesn't go into the cab.

Recently I took the dog house off my 2010 Tioga and saw avocado pits and macadamia remnants in the valley of the V10. I didn't see any wire damage, but I vacuumed everything out and sprayed the heck out of it with that same spray, then opened it up a week later nothing was there. I sprayed it again and they haven't returned yet. In fact it was just opened up again because I had it smogged, and no sign of any more activity.

By the way the motorhome is parked in my backyard right next to a macadamia and avocado tree. Very convenient for the squirrels!

Good luck, and by the way you can spray everything with it, like the wires and the cable sheaths, and they even recommend spraying down around the tires.

Put some traps, either sticky or snap. You have to get rid of them not chase them away.
