We had an actual swarm of wasps a few doors down the street. I often get wasps in the house, but I can't bring myself to kill them - I just gently wrap a thick tea towel round one as it buzzes on the net curtain, and pop it outside. Same with bluebottle flies - I rather like them and carefully help them to freedom.
My neighbour has a horrible fly-swatter, and thwacks any flying creature with it. Her walls are simply covered in the remains of squashed flies and wasps.
But spiders ... er ...EEEEEEEK!!!!!
