Mousetraps are a perfect way to trap a mouse. First, get yourself a mouse. Your local pet store should have some available for sale. If you have multiple mouse traps, you will need multiple mice. Get yourself a female mouse and a male mouse. Put them in your house, spill some food on the floor and wait about a week. Now that you have lots of mice running around, it’s time to setup your mouse traps. Set the mouse trap on the floor. Put some peanut butter on there and set the trap. Now wait about a week.
