When I lived in the UK I had a job working at a farm stockyard, & one of the things I had to do was kill mice, but as my boss was too cheap for traps or poison I had to do it by hand... well, steel-reinforced boot actually, but the thing was the mice where extreamly sensitive to any sound & would run, so I had to sneak around the meal shed & take them by surprise.
However, the mice that come into my current workplace at the start of winter react compleatly the other way, the louder you are the slower they move.
Mice suck, make walls fall down, & spread disease & fleas.
