Bug Scout 1979
Good Sanitation Cuts Fly Problem
(Tom Turpin, Entomologist, Purdue University)
Hey, Bug Scout, from here it's hard to tell whether the flies are attracted to you or the manure pile.

Sanitation is an important aspect of fly control.  Flies found around farm buildings develop in moist manure or other wet decaying organic matter.  Some flies can complete a generation, from egg to adult, in as little as 10 days during August.  So, it is easy to see why fly populations appear almost overnight.

Insecticides can effectively kill flies.  However, without proper sanitation, use of insecticides is a losing battle.  Manure removal at least twice a week is needed to break the breeding cycle.  Let wet manure dry and dispose of old damp straw or hay away from buildings.

You can probably control more flies with a pitchfork or manure shovel than with any insecticide on the market.  And you really can't control flies without a spreader!
