I use bounce dryer sheets, they smell better and rodents don't like them.I can't remember what is in them but there is something poisonous to them in them and they stay away. I used to have a problem with mice on my bikes in the winter, since the dryer sheets I have not had an issue.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
