We have experimented with many traditional chemical and ‘organic’ methods of managing fly populations. I can say that the use of balEnce and the technology of utilizing existing bison behavior have far surpassed any positive result we’ve experienced. We experience less fly management requirements with each passing year, which supports the hope that our farm, as a natural system, has become much less ‘fly-friendly’ with each year.

Fly control for Bison is a challenge for any fly management program but there is a solution. BalEnce Fly Spray, when sprayed in the wallows or dusting areas works incredibly well. Depending upon the location and time of year, house flies, stable flies, horn flies and face flies can all be problematic for bison.

Bison attract a variety of flies and treating them with toxic chemicals is not a good idea. The effect on the animals is not good and the chemicals don’t last. Tim Frazier of Frazier Bison has been using balEnce Fly Spray for years and is a true believer. His tried and true technique is to spray the wallows with double strength balEnce — “What you will see is a reduction in the population in the first 36 hours, followed by a cycle of reduction [ongoing] and each year will be less management intensive because of lower and lower populations. You will actually be turning your bison into fly traps, and causing the flies to kill other flies by contact. This has been my experience. I have also sprayed the bison occasionally if I get a ‘bank-up’ of fly populations.”

The active ingredient in balEnce products is a naturally occurring fungus (Beauveria bassiana).  This fungus specifically targets and kills the bison flies but does not affect humans, the bison, pets, or the beneficial insects that are so important for our environment.

In order to provide our bison customers with a complete solution to their bison fly control problems, Terregena includes parasitic wasps, also called fly predators, as an important part of its fly control product line.
