That statement was a tad misleading. I get many calls about "bees" and very often the caller is either talking bumbles, "are they round and fluffy" question or "are they wasp like" If the answer to the first is yes it is usually bumbles, if the answer to the 2nd question is yes it is usually wasps, though occasionally it is a swarm of bees which of course is what I want.
If it is wasps and they are bothering the caller I advise on how to destroy them, using a powder called Nippon sold as an ant killer. If I can I persuade them to leave well alone, both wasps and bumbles as both to a lot of good. Bumbles pollinate many species that the shorter honey bee cannot manage, and wasps hoover up loads of greenfly.
I spoke with a wasp expert and he astonished me by saying there are on average one colony per acre. As a beekeeper I run a wasp trap in my apiaries if they are being a pest which they are some seasons though this back end they were barely present at all. One of the advantages of my feeding regime now is I don't use syrup and it appears the wasps are not tempted by the smell of it. I now put on blocks of Bakers Fondant around now. Works a treat.
I hope that is a bit clearer.
