Fly Predators are nature’s own enemy of all common manure and rotting organic matter breeding pest flies, including the common house fly, horn fly, biting stable fly and lesser house fly. In the natural environment Fly Predators serve as a major check of pest fly populations by destroying the next generation of flies in their immature pupa (cocoon) stage. Fly Predators are tiny, completely biteless and stingless. They never become a pest themselves. Because of their small size and the fact they live their entire life cycle on or near manure (where the pest fly pupa are typically found), Fly Predators go virtually unnoticed.
The current mixture of species marketed under the trade name Fly Predators include: Muscidifurax raptorellus, Spalangia cameroni or Spalangia endius and Muscidifurax zaraptor. and at times insignificant quantities of other fly parasitoid species. These species have been proven effective by both scientific tests and from decades of actual usage.
There is no known method of fly control that offers 100% eradication of pest flies. Fly Predators do not totally eliminate the fly problem, they minimize it, and often dramatically. The key is to maintain a sufficient Fly Predator population to stop each succeeding generation of pest flies. Because pest flies reproduce nine times faster, adding supplemental Fly Predators every three to four weeks during warm months keeps the population balance necessary for good fly control.
However, you must release enough Fly Predators to control all the fly reproduction in the area. You treat the farm not the horse. For example, if you board at a commercial stable, ordering Fly Predators for just your horse will not be sufficient as the flies that reproduce in the neighboring (within 1/4 mile) horses’ manure will easily reach your stall. Get the stable owner to use Fly Predators and then everyone’s horses will not be bothered by flies.
Others offer different brand fly bugs but they’re not Fly Predators. The species are different and the difference in performance can be huge! One competitor’s product is 90% Nasonia vitripennis, a species which is notably lacking in scientific support for effectiveness with large animals. Eight published evaluations reported that Nasonia was ineffective. The only positive evaluation we could find was for chickens.
By comparison, the Genera of our species have 43 positive published scientific evaluations for fly control with all kinds of animals, large and small. Plus, we guarantee live delivery of the quantity ordered, and typically, the total season cost is lower due to needing fewer shipments of Fly Predators for many locations. Don’t settle for anything less than real Fly Predators.
The other huge difference between Spalding and any other fly company is the comprehensive information we provide on all aspects of fly control. From our knowledgeable phone reps, publications, our videos, and our web site there is no better source to become fly savvy which leads to fly free. Mackinac Island is an example of how important good information is. They had been using a different competitor’s fly bugs with poor success due to inadequate and incorrect guidance from that vendor. The vendor was even selling the island House Fly traps when the big problem was Stable Flies. After switching to Spalding, Mackinac’s fly problem is history.
