I live in the country and my driveway is long and slick.  I can not
drive my car down to the house and have to park it up by the road
alongside the neighbors corn field.  Then I have to drive my 4WD truck
or my tractor up to the car.  I have parked the car up there for some
time, but this year I have mice building a nest on top of my engine
(intake manifold).  I keep removing the nest, but they keep rebuilding
it.  Now they are chewing away at the hood insulation to make their
nest.  They also chewed a vacuum hose, and had the choke pulloff
jammed with their nest which caused the car to flood last week.  I am
getting real pissed !

I use the car at least 5 days a week, but they still continue their
nest.  I find it hard to believe the nest stays on the engine when I
drive up to 60mph, but it does.  Yet, I have a feeling if I put a snap
trap up there it will blow off the engine, and so will mouse poison.

What can I use?  A friend said to try moth balls, but I think they
will blow off too, unless I can encase them in some wire screen or
something like that.

Any suggestions, please?

Thanks

Gary
