Many moons ago when I still lived out west, we had a mice plague.
One night I sat in a dark room with 3 mice traps and a bucket.
1 trap in front and one each side.
By the time I'd empty one trap the others had gone off.
65 mice in half hour.
That was in the house. For the shed we used to empty the pellets from shotgun shells and replace them with wheat.
Open the shed door and blast away. The wheat would kill mice but not damage anything else to much.
