I've had mice in my house growing up a few times, as well once when I was on my own. It's pretty terrible. One good way is setting up a water trap so they drown. Another is good old fashion mouse traps. The drowning method works better because it gets more but I don't recommend it if you have other animals or kids around. There's also this guy on youtube who does mouse trap videos. You might find whats best looking up various mouse traps on their channel. Can't think of the link at the moment but it wouldn't be hard to find his content.
