I actually had a skunk problem for a couple years. Found this remedy online. Soak tennis balls in ammonia over night. Next day, roll the tennis balls under the shed. It's preferable to do it when you know they're out, but I never worried about it. The ammonia smell makes them think another animal has come and pissed in their territory. They pack up the fam and leave. I did it for two years straight. They left both times and (knock on wood) I haven't had skunks under my shed in at least 5 years, maybe more.
Robins are the first sign of spring here. And for that, I love them!
