Review on Farnam SimpliFly Feed-Thru Fly Control for Horses: Effective Solution to Break and Prevent the Fly Life Cycle - 3.75 lbs by Moises Dzihic

This is the first year that we have used a fly control supplement on our horses and we are very pleased! It's so easy to feed, just mix it with horse grain and watch the flies go away. Despite sprays/wraps/etc. mostly plagued by flies. This year the problem with flies was minimal. We still had a few flies but I'm talking about 85% less than before. Will definitely be using this product again in spring.
