In our old house we had a dobber of a wasps nest. No kidding, it was the size of a proper black bin bag.
The most interesting way to get them would be to pretend it is ww2, the germans are going to take blighty once they have control of the skies. It is down to the "few" to save us from Goering's mighty blitzing luftwaffe. You are the RAF. The wasps are the germans. Put on a flying helmet and goggles, leather jacket, flying boots, gloves, yellow mae west. Run up the ladder shouting scramble, chocs away ginger, bandits at 3 o'clock etc. Then proceed to pick them off one by one with a badminton racket. Everytime you get one, mark it off on the side of your car. Every now and then, come down the ladder, have a bladdy good sing song round the piano with pints of frothing ale. Drive around the countryside in a little sports car with a labrador in the passenger seat. Keep us posted on progress as you go eh?
I mean fer ****'s sake, put the magic back into wasp eradication why don'tcha????
