Will Keeping Blend Door Closed Keep Rodents Out?

Will Keeping Blend Door Closed (recirculate cabin air) Keep Rodents Out of the cab?
I think they can still get to the cabin air box, but could they get inside the vehicle?

 

It will definitely help having an extra obstacle. I made a habit of closing mine nightly at home for that reason and to keep dust out.

 

@ElectroBoy had a nice write-up about adding some metal mesh over the fresh air intake at the base of the windshield. You can find it here.

 

Ugh, this is a huge concern of mine. I work 4 months on (on a Navy ship) followed by 4 months vacation. My son wanted to use my little Ford Ranger and it took a lot of work to keep it running till all the corn finally blew out of the exhaust. My neighbor kept his corn hopper in my building unfortunately. Then, I geve my almost 25 year old Victory motorcycle to my son and it was the same thing.....corn had to get blown out. I need to close up/screen off all opening including the exhaust.

 

Joking, but not. Maybe something like this is an option for your barn.

That might work if it keeps chipmunks out too. The struggle is real. Two trucks, two quads, two mowers, a boat and a tractor.

 

Rodents hate the smell of mint. I spray my engine bay with peppermint on a regular basis and also add a few drops inside the cabin.
