We live in the Ozarks, and the old-timers and environmentally minded groupies 
in our area have told us that hanging a zip-lock bag of water above our 
entrance door will deter the flies entering our home. There are a lot of flies 
this year with the drought again, but it seems to work very well.  Now we want 
to know why!  None of the people that told us about it have a clue and I didn't 
find anything like this in your archives.  I did look.
