I'm not keen on killing things. Generally if some creature isn't having a go at me I'll leave it alone.
Today though I spotted a very small wasp's nest on our back door and when I hunted around there were another five nests attached to the walls or beneath the roof overhang. It was easy enough to move the little ones with five or six resident wasps but I hesitated at the thought of shifting something with twenty or thirty occupants. I hear that wasps sting!
So, I took a leaf out of Slobodan Milošević's book and slaughtered the whole lot except I did it with a lavender scented flyspray.
