Spalding Laboratories, spalding-labs.com, is the largest provider of natural pest fly control to the equine, dairy, zoo and other market segments. Our product, Fly Predators, is a tiny beneficial insect that stops flies from reproducing. While Fly Predators are the safer and more effective alternative to pesticides, they still generate the question, “do these things work?” from prospective customers that have not tired them before.  Customer testimonials are a core part of our marketing.
