The genesis for Spalding Labs was the awful fly problem my mom had around her Arabian horses. This was 1976 and in the era following Rachel Carlson’s book Silent Spring that made everyone aware of the dangers of the “miracle” pesticides that we were using at the time. Fly Predators have become the preferred method of fly control for all types of animal owners and others with an abundance of rotting organic matter that creates flies. We’ve served hundreds of thousands of customers and the majority of them use Fly Predators as long as they have their animals. Another notable long term (30+ years) customer beside Dr. Miller and Bob Buell is Pat Parelli.
