Horseflies and many other species of biting flies tend to develop on the edge of bodies of water and since they are strong fliers these breeding areas can be near or far which makes finding the source next to impossible. You can apply a product such as Talstar P around the pool area and flies that land on the treated areas will be eliminated. Using Talstar will give some relief but since these flies can fly over treated areas it can be tough to get complete control. Relief should be on the way soon however as horsefly season is usually on 3-6 weeks long
