Step two: Find their home.
Like we said, if there’s one, there’s probably a whole family. So, find out where their mouse motel is located, and kick them out for good. A professional exterminator can likely help you out with this if searching for mouse homes will make you a little queasy. Once you’ve tracked that down, you can set up traps around that area (the exterminator will also be able to help with the ideal spots to place them).
