Had some of the sticky traps a little while ago. They catch the buggers. They break their legs trying to free themselves. I found out about them (my flatmate 'phoned me from the next room whilst I was still in bed) hours after capture. They'd been struggling all night. I had to dispatch them with my boot. There's nothing humane about a sticky trap.

I don't like killing.

Best way to keep mice away is to remove the incentive. Surely? Trying to get flatmates to keep things in cupboards... Almost working.

Good thing I'm going into the profession I am. I'd hate for a killer to do so.
