I love mice - but I can't bear one in the house. They make a mess and chew things they shouldn't like bills and electical cables. They spread Salmonella. A countrywoman, I allow no mouse to take up residence with me for long. But the latest one was defeating me. He left his traces in the kitchen cupboard and stole the bait off the six traps I put out to catch him. I tried everything - cheese, chocolate, peanut butter and bacon, all to no avail. A friend recommended the bait and mousy was quickly caught. But it soon became obvious he had left a widow! No problem - within a couple of days she too succumbed to the attraction of the Big Cheese Rat Bait. Home is my own again.
Incidentally, I am convinced that both animals had a quick, not inhumane, despatch.
