We're having a bit of a problem with bl**dy jaspers in the garden- I read once that a glass of beer with detergent in attracts them then they can't get out. I tried this and attracted *no* wasps at all, in fact we had a citronella candle going and this attracted 1 wasp, when it's meant to repel them
bl**dy jaspers - anyone got a favourite trap-bait or any other ideas?
