Buying advice

When choosing a fly repellent, consider your horse's sensitivity, climate, and activity level. For heavy sweating or water exposure, choose a sweat/water-resistant formula. Natural options like Fly Predators work well as a preventive but require time to establish. Always test a small area first to avoid allergic reactions. Rotate products to prevent insect resistance.
