Review on Farnam Endure Sweat-Resistant Horse Fly Spray, Kills, Repels, Protects, 128 Ounces, Easy Pour Gallon Refill by Roberta Gonia

We use 3 to 4 gallons of this spray per summer on our farm, so I order 4 at the beginning of summer to save money by buying in bulk. This summer was especially bad so I ran out early, and not much seems to work on flies but Endure, so I had to order more. Luckily I found Walmart had a single gallon for the best price going! So great not to have to place a giant order and pay an arm and a leg for shipping. Good product, great price, super fast shipping. I do typically have to apply every day, however, and of all the products I've tried this is the best. I've never had a horse have a reaction to the product, and the sunscreen does seem to help with sunburned coats. More effective for mosquitos than biting flies, but it does help immediately after application.
