Wasp warfare.

Pete - the bees are buzzing round the flowering shrubs, which are far away from the non-flowering Prunus hedge that the wasps are swarming around. So I can leave the bees safe with my chemical warfare.

I did post this with some trepidation because I know I'm doing wrong. I'm usually a very, very conscious gardener, but all bets are off when it comes to wasps. I want to live with them - but no matter how much I try, I just want them gone!
