It is Summer and there are flies about so what is the best way to get rid of them besides moving to a cold climate!
From following the Casey Anthony murder trial we know that flies show up at the first sign of decomposition. So I guess the best way not to attract flies is to avoid having food and other organic matter decomposing near where you are located! Short of that it looks like hanging bags of water in the day (I believe there is some artistic value to doing this much like a previous neighbor that hung aluminum pie pans to scare birds from his garden – it didn’t really scare the birds but it had an interesting artistic element to it!) and lighting lavender candles at night along with the jar of water/green apple dish soap help. And of course getting a huge exhaust fan like the one’s they use in poultry houses could blow the flies into your neighbors yard!
