Every farmer knows that having manure odor management and fly deterrent tactics are essential for a good quality of life, for both humans and animals. But getting there too often depends on chemicals, pesticides and toxic methods. It does not have to be this way.
And now is the right time to develop those fly management tactics. Manure odors and fly populations are at their highest levels during summer’s warmth. During summer in livestock shelter areas, with even small accumulations of fresh and decaying manure, the odor-fly relationship is cause-and-effect as manure and urine odors attract a variety of types of flies.
This we know: fresh air that is free of manure odors does not attract flies, and manure that does not produce an odor does not attract flies. Can an ideal manure odor management and fly prevention program for livestock shelter areas exist in farm practice? The ideal program results in a livestock shelter area (barn, stables, loafing shed) so free of flies, full of fresh air and chemically safe that one could comfortably picnic there with family and friends. Our image of ideal success — the livestock shelter as picnic zone — guides us to its establishment in the real world.
Real Foundations for Manure Odor Management and Fly Deterrents
The tactics to start with are: (1) a cluster of standard, low-risk, fly-prevention tools to decrease an existing fly population. Several weak items working together can support each other’s actions; (2) an emphasis on decreasing fly attractant levels typical in livestock areas (the volatiles produced by manure, urine, decaying bedding material and spoiled hay/feeds), thereby preventing fly population increases and usually ensuring its decrease. Decreased concentration levels of fly attractants also make the program easier to accomplish by decreasing the need for the prevention items in (1). Further, with consistently very low levels of manure’s attractant volatiles, area fly traps’ attractant baits become relatively more effective.
