I have tried various fly sprays, but nothing seems to kill these, also we have loads more than usual. Has anyone else got this problem and any answers would be appreciated. Many Thanks
You can buy Vapona fly killer window stickers, which look like sunflowers. You stick them on a window, the flies are attracted to them then they die. They are very effective.
you know places abroad hang bags of water up outside doors and windows to deter flies. Don't know how it works but apparently it does so i am going it try it too
