diddy1 - 25/8/2009 13:51 don't worry. The wasps will be killed off soon enough when the Giant Asian Hornet eventually crosses the channel ! Then you will really have something to worry about.
I think they may have occasionally visited our shores, but in small numbers.
About 13-14 years ago when I was living near Southampton, this 'thing' flew into my house on day in June that year. It was wasp shaped and coloured, but the only difference was that it was about THREE INCHES LONG!!! Being rather scared of wasps, I refused to go any where near it, especially as I could see its sting from the other side of the room. I sprayed some fly spray into the room, then beat a hasty retreat.
Later, when dead, transferred it to a large jam jar, the squat 2 pound variety, and this thing from nose to sting was as long as the jam jar was in diameter.
Earlier this year, a similar monster flew through my garden here in Devon. I heard it before I saw it, but it was obviously on a mission as it flew straight through the garden from north to south with no deviation, then off down the hill until I finally lost sight of it.
By the way, do not squash wasps. They release a pheremone that tells the rest of its mates its being attacked. This causes other members of its colony to fly out and to be aggressive, one reason why if you squash one wasp in the home, you then get lots more in.
