Dig a pit in your garden 100ft deep and hammer a trail of frozen sausages into your lawn leading from the shed to the pit and chuck some in the bottom for good measure. Coat the sides of the pit in goosefat so there's no chance of escape. Catch the rats in the pit then either fill it in, lower a cat on a rope or drop a gallon of petrol and a match
