Review on 🐴 SimpliFly Feed-Thru Fly Control for Horses - Disrupts and Halts the Fly Life Cycle 10 lbs by Maribel Hernandez

My first season of trying this started in April. It's easy to use, horses love it and the fly population has decreased noticeably compared to years past. Nothing will completely kill flies - you will always have them if you have horses. So it's nice to find affordable products that help keep them under control, and Simplify certainly does. However, the company's claims of 97-100% efficiency are ridiculous; I would estimate that it's around 50-75% for us. But it's enough for me to make it worthwhile, especially when combined with other methods (fly bags, masks, occasional misting). Both of our horses went through a 10 pound bath in about 2.5 months so at $70 that's about $15 per horse per month. For us, the fly reduction easily justifies the cost of this product.
