I own a little john boat and store it in a private garage in a "nearly
rural" part of town. Mice come into the garage from the surrounding corn
field. I have noticed mice pellets in the boat and once after bringing the
boat to my house, noticed a dazed mouse moving down the driveway and finally
finding the grass.

I do not want to kill these mice--I am afraid if they die in the insulation
under the flooring, the boat will stick of rotten mouse for a long time. I
do want to make the boat unpleasant for the mice--get them to leave.

Thanks in advance for your ideas.
