A friend who lives in a mobilehome at the edge of town is having
problems with racoons.
Other than eating up his plants and keeping him awake at night
frolicking around on his roof, his girlfriend is terrified of them.
What are some methods he could use to get rid of them?
Shooting is out of the question.
Someone told him to try ammonia but he says it doesn't seem to do any
good.
