We’ve received some wonderful comments over the years as folks discover Organic Cowboy and our fly parasites. One client from Texas shared, “We have been using fly predators for our horses and cows for years, and when we switched to Organic Cowboy, we saw a huge reduction in flies. They are sent more often than other companies, and the quality of the larvae seems to have a much higher hatch rate. We had these little guys everywhere on our property doing a great job!” — K.R.
We truly appreciate feedback like this, which comes from boarding and training facility owners, breeders, and everyday horse owners alike. They all share a common goal: the health and welfare of their horses. Effective fly control is a vital part of that.
In the sections below, you’ll find valuable insights, particularly from a conversation with Kevin Meyer, a respected trainer in Wyoming. This discussion will provide you with the framework to optimize biological fly control in your unique setting.
It’s worth noting that people often refer to fly parasites as fly predators or eliminators; they all mean the same thing. These are parasitoids that, like predators, target and eliminate their prey—in this case, fly larvae. The species of fly parasite used in your program is crucial, which is why we stick to those with proven field-trial data supporting their efficacy, backed by USDA and university studies.
