What Is the Most Effective Way to Get a Mouse Out of My House?

My wife told me a few weeks ago that we have a mouse in the house. I checked all the evidence and it checked out. All the tell tale signs of mouse in the house were there --snacks eaten, doo-doo droppings, the whole thing.

We got a few of the newest and hottest traps you could buy and put them all over the house, and I have nothing to show for it. Then, this morning, my wife texted me and said "I saw the mouse!" My response was, of course, brilliant. I said, "What was he doing?" Not helpful at all, but I had a good laugh.

Now that she has seen it and is sufficiently grossed out, I need to take this seriously. In fact, this morning, she was sending me Liam Neeson, "I will find you and I will kill you" memes. She even referred to our situation as "war." To say the least, my weekend has now changed dramatically, and the entire focus of it will be to rid my home of this vermin.

So what do I do? How do I best get rid of it? Erica did some research and told me most people say that the old school traps work best with peanut butter as bait. Is that true? Help a dude out -- I would like to get this over with.
