It's been mentioned several times already but raccoons hate radios and music. A neighbor had a 'coon litter born in her storage shed that was attached to the house. She didn't want 'em killed but wanted them gone. I had her put a radio out there and left it on, it was a talk radio station. Day or two later I saw the mama carrying the babies over to the nearby woods in broad daylight in the afternoon. About the time Rush Limbaugh was on that station. I guess raccoons don't like Rush, and they never came back.
