Roy Here in Northern Ireland the fly is out and about from late May for approximately four weeks. They reach a peak in my garden in mid June. The last one I saw was in early July. I know I cant kill many but I have a few fly swats around the garden so there is always one to hand. I also carry one in my back pocket while working in the garden. There are a couple of myths about the fly. "They don't fly high" is rubbish.. I tried to kill one in my greenhouse this year that was inspecting my Nerine sarniensis. It managed to get out of the door and I clearly saw it head over the house. "They don't fly in shade" - oh yes they do. Last year I killed one that was inspecting troughs on the north side of the house. One chemical that does work, if you can get it, is Dursban. Sprinkle some granules around the base of your bulbs. I have been told Provado may work. Hot water baths work also. Have you considered you may have trapped a male and female under the screen that were in bulbs in 2007.
