The use of FlyRaptors on a regular basis along with fly traps.
The need for chemical sprays can be greatly reduced or eliminated by adopting a program of Ecological Fly Control. Such a program includes regular releases of fly parasites aimed at preventing flies at their sources, or breeding sites. It also includes the use of fly traps which will help eliminate the adult fly population.
Using good sanitation practices.
No fly control program will be successful if manure is allowed to pile up around the premises. The most effective method of manure management is to spread it thinly on fields where it will dry quickly as the pest larva are highly susceptable to this drying process. If spreading isn’t practical the manure should be piled. This reduces the surface area and results in heat generation within the pile, driving the pest larvae to pupate near the surface within reach of the fly parasites. Elimination of as many wet areas as possible and the use of hydrated lime on the areas where your animals urinate frequently is also very helpful.
The use of pesticides should be aimed at adult fly populations.
Sprays may be safely used in non-manure areas where flies congregate, such as rafters in the evenings, fence rails and barn sides in the morning sunshine and shady places in the heat of the day. In addition, sprays and wipes may be used on the animals themselves. Applying poisons to the breeding habitat does more harm than good as fly parasites and other beneficial organisms are thus destroyed. Bait stations can draw adult flies to areas away from your animals and kill them there.
