Ratting with smoke, shotguns, airguns and terriers

There's more than one way to catch a rat. And if at first you don't succeed, try, try again. We start with smoking 'em out with a chainsaw and shotgun, and then let the terriers have a sniff. The last resort is to sacrifice some left-over Chinese takeaway to see if they fancy a late bite and stay still long enough for us to take aim with an air-rifle. Dedication... and great fun.
