Last week I discovered partially eaten food and mouse droppings on my desk, so I went out and got some mouse traps. Well, a few days later, and to my surprise, I caught not one but two mice (and I had set up two mouse traps). I hoped this was the end of the problem, but this morning I awoke to find more droppings on my desk.

I'm afraid that the stupid vermins reproduced or something...What should I do?
