Hoover them, its the only way I can bear them, I cant stand the idea of swatting them, if necessary i spray a teeny tiny little bit of fly spray in the nozel with the hoover still on if i have a few of them and theres any chance of them being still alive, that way you dont use a load of the stuff, its contained and your not killing any friendly spiders or other little critters...
Bluebottles are horrid...like flying specs of ****e :)

I would get some flypaper, I realise that it is not to everyones taste to have a sticky ribbon covered with dead flies but they really work and are very green, no propellants, chemicals or any nasties. They are made from some kind of sticky gum andpaper.

Actually, Johnny I remember that sticky paper - awful stuff if you happen to brush off it! I think I may get some for the rooms not in use(empty nest situation!) and try it out.
Thanks
