Hey all, we had mice in our home too... and it really sucked!
I experimented with traps and poisons, but found them to be too dangerous (I have pets and little children) -- and also in humane. NOt to mention that I read the mice carry multiple diseases.
I discovered a little company out of North Dakota, call Earth Kind (www.earth-kind.com) that has an all natural mouse repellent -- called the mouse pouch. YOu simply put these pouches in the areas that they populate (these pouches emit an odor that mice HATE)..
we did this 4 months ago, and havent seen a mouse since...
