Mouse nest in air box

[Dave Hess]

How often do you find a mouse nest in your air box ?

I replaced an air filter on a relative’s car and it looks like leaves and grass bedding.

It took a while to build nest so I wonder if mouse escapes when the owner starts engine in the morning and returns when the engine cools down at night.

I have a K&N filter in my air box. It is coated with K&N rodenticide so never a problem.

I had to quit putting in the cabin filters on the Gen Coupe. They would not last but a couple days before the mouses moved in.

I had a mouse nest in my M5OD bell housing. I discovered it when we dropped the transmission to in my van to replace the slave cylinder and do a clutch job while things were taken apart. I found it an interesting place for mice to take up real estate.

There’s something that involves peppermint that keeps them away.

Fortunately, I don’t have that problem.

I have never had any. I guess that is odd because the truck and Trans Am sit...a lot!

Ive heard that to . Get some Peppermint Oil and spray it around the engine

It has happened to me twice. I have added a hardware cloth barrier at the air intakes on my vehicles.

I will buy some peppermint oil.

Every vehicle I own has ¼" hardware cloth (steel) over the intake to the air filter, and air filter restriction gauges.

I've had a few nests, and this is the only way to prevent them IMHO.

When I was a mechanic we had a vehicle (don't remember what it was) come in which ran very poorly and would barely idle. The airbox was completely filled with nest, and the air filter was all chewed up. There was nest into the intake as well.

A shop vac and some mice later it got cleaned up. That engine ate a lot of dirt and used a lot of extra gasoline due to Fifel.

That looks more like a birds nest!

Peppermint didn't do the job for me.

Not quite as bad as it looks. No wire damage. New hood liner was $190, though.

All manner of nesting is common here. Blower motor nests drive me nuts. Seen that on Tacos, Subarus, GMT800s and more.

Once they start in on hood liners or the "battery blankets" that stuff goes right in the trash. Also best to remove any plastic engine covers because they feel safe under there, and fuel injector wires are tasty.

Had one on top of an NP261 in an '02 Silverado. Never knew until I dropped the t-case for other reasons.

First thing I do to any vehicle with a hood liner is to remove it. Also engine covers as D60 mentioned. I'll deal with a bit of engine noise over chewed up wires right before I'm supposed to leave on a trip etc.

I placed a couple of these near where I park the vehicle. Haven’t had any problems since.

It could be much worse. This is the throttle body connector of my Scion.

I thought the throttle body had failed and had started to disconnect it when I felt a wire poking my arm.

I have a vehicle that didn't have a cabin air filter from the factory but was setup for one.

It had been sitting for a year before I got it and I cut a slot for a filter. I ended up having to vacuum the mouse nest out. It was all around the blower motor also.

I still haven't been able to get it completely clean without pulling the dash but I vacuum it out again every time I change the filter.
