Method to catch multiple mice?
Try searching "mouse bucket trap". There's a ton of different variations, so I'm not going to go into too much detail. But basically it's a bucket, a ramp, some peanut butter, and a rotating mechanism.



If you want to kill the mice, put some antifreeze (or other poison) in the bucket. If you're looking for less lethal, leave the bucket empty, or put in some wood chips or similar.  

Notice that I said "less lethal". If you leave mice in the bucket too long, they will get hungry. And mice have no qualms about going cannibal.
