Unwanted House Guest

For the past couple of weeks we have had an unwanted house guest. Let's call him Ralph. Ralph showed up unannounced one night & hasn't left since. Ralph is a skunk & he is made a home for himself underneath our house. Every time he gets frighten throughout the day we experienced a very strong odor of skunk. It comes up threw the vents & circulates through the whole house. I got up the other morning with Rex (our dog) about 4:30am. As we are making our way outside, there is Ralph sitting at the bottom of our stairs. It became a battle of the wills, me unable to move (for the fear of being sprayed) & Ralph not moving (for the fear of Rex). After what seemed like forever Ralph quietly moved back to his home underneath our house.
The neighbors probably think my husband is crazy. He leaves for work between 5:30 - 6:00 am. As soon as he goes outside he states really loud, "I am going to the car now, I hope you are not out here". He is trying to scare Ralph so he doesn't get sprayed. For someone that doesn't know what is going on, it must be quite funny to watch! So if anyone has any ideas on how to get rid of skunks, it would be greatly appreciated. The kids are good. Taylor goes to the doctor on the 5th of March for her 9 month check up!
