Biological fly control for your stable

Fly parasites are a time-honored tool in the battle against pest flies, killing flies long before they become adults that spread disease and bother you and your horses. Our harmless gnats-sized guys prey on and kill flies, like a predator, the natural way. And as you remove chemicals, fly pupa-devouring beneficial predators such as Hister Beetles can thrive and enhance the overall fly control at your horse barn.
