Flies are like pennies, they can add up to real dollars.

My calendar says early June and fly season in the northern climates is under way. Here in Michigan, now is the time to be implementing your fly control program. The two major species of flies that cause the most serious production losses are the horn fly and face fly. The horn fly alone is estimated to cause animal losses to the United States beef industry over 1.5 billion with current market prices.
