Apparently they are already active in Southern Europe as well, not only killing bees but also attacking people selling shrimps on fish markets over there. A colleague of mine has a bee-keeping friend in France who has to battle the wasps at times and he will ask him to send us some dead ones. It probably is only a matter of time before the wasps show up here, either in person or in the press as a possible thread to local wild life (including man).
