House Guest

For the past month or so, I've been telling my husband, I been hearing some strange noises coming from the ceiling, especially in the morning when I'm stepping out of the shower. I've come to the conclusion, he thought I was crazy because he's chosen to ignore me. He's never heard the noises. Us ladies, like to call it selective hearing. Anyway, Elena, pointed out to him one morning a squirrel crawling through the gable area. Now, that he has witnessed it, I've obtained my credibility.

Now, does any one have any suggestions on how to get rid of our unwanted house guest(s)?
