[Dujon] OK, then my advice (and always had been, truth to tell) is to slam them all on the head with a garden spade. Smash their little brains out. I was trying to phrase it delicately for the sake of the animal lovers who might read this, but phooey... sod 'em.
[pen]I don't do that myself, but if someone is going to the trouble of a live-capture trap, I figured they wouldn't then want to send the mouse to its maker. Personally, I get my Jack Russell to worry them. Very quick death, although he growls when I don't let him chew on the body. Mouse guts everywhere? No thanks. AND I'm a vegetarian. But my dog isn't.
Look you lot - all this killing stuff is making me feel a bit queasy. In fact it's completely put me off the crispy fried mice ready meal I was about to microwave for my lunch ..
