I remember reading about this last year, from what i remember its down to climate change and european bees and wasps coming to live here, transported in shipping goods etc too, then they have mixed in with ours (or replaced them) to produce these goliath sized beasts that you swear will crack the window pane if it hits it any harder!.
Also, I seem to remember that some chemicals and pesticides that we insist on sloshing over all the fields n stuff are making them into double hard resistant little bastards and general fucking up of the whole ecology cycle......which is nice:S .
It will be like alfred hitchcocks film only "The Bees" rather than "the birds"........do birds eat bees and wasps? Whats thier predator? Theres a downturn in birds too in this country so that may have something to do with it. These gravel gardens, no hedges and excessive sized decking instead of lawns craze is contributing to the decline from what I believe - so think twice about doing a ground force peeps!. birds cant pull worms from 4" thick worth of pebbles, and cant really build a nest in a little 'box' plant in a plant pot near the decking which used to be a lawn!.
Its a good job I hardly ever go outside innit,lol, cant be doing with wasps
.
Im gonna patent a hole free house, where no insect can get in. Sounds lush to me!, no more spiders,bees,wasps,woodlice or even slugs in the house! That would be excellent.
