Raccoons are an almighty pain in the ass.
They used to get caught in our window wells until we finally got decent metal grates to cover them.
I agree with the live-trap/relocate option. We trapped one in a "have a heart" trap that was so fat, he was squishing out the sides. Man that sucker was pissed. Took two of us to load him in the back of the truck and had to upend the trap to get him out. I've read that you have to go a fair distance to relocate though or they'll come back....
