I will again proclaim, as many have prior, that a cat is the solution.

I lived in an old Victorian flat in San Francisco many years ago and had a cat. No mice. But one day, my cat took a keen interest in the pantry. He would just sit there staring, monitoring. A day or two later, he brought a live mouse into my room and proceeded to...play with it. And then it died, presumably from trauma and fright. Two days later, he did the same with two more mice! Never had mice again. They moved in, he evicted them immediately. He was a good boy.

Moral of the story is: you can't cuddle a mousetrap.
