Live catch wouldn't really work round here mate, well they would but only till some little shit nicks it or stamps on it . If i can find a way of hiding it or lofting it even i might try the one i made as it was free.
Still waiting for a stoat though on my ditch tunnel, i'll get one there though coz i often see stoats there. Does pissing them on the trap really help? I would have thought that when they dump their stink gland when caught would be enough?.
