Fly and insect management is key to a happy and healthy horse in the summer time heat. Swelling, inflamation, hives and stomping are all negative effects from biting insects. Fly repellents are a must-have in barns during peak fly season. Easy-to-apply spray or roll-on formulas each dispense effective product to all vulnerable areas. Applying fly spray also decreases the risk of disease spread by biting insects by encouraging them to not land on your horse.
