To protect horses and ponies from Horse Flies, House Flies, Stable Flies, Face Flies, Horn Flies, Deer Flies, Gnats, Mosquitoes (Culex spp.): Thoroughly brush the horse’s coat prior to application to remove loose dirt and debris. For dirty horses, shampoo and rinse thoroughly. Wait until the coat is completely dry before applying this product.

Avoid getting spray into horse’s eyes, nose or mouth.Wear rubber glove or mitt when applying as a wipe. Spray or wipe horse’s entire body while brushing against the lay of the coat to insure adequate coverage.
Reapply every 14 days for fly control normal conditions for initial applications. As protection builds, reapply every 14-17 days. Reapply every 5 to 7 days for mosquito repellency. Also, reapply each time animal is washed thoroughly, particularly if with shampoo or soap.
