Opti-Force Fly Spray is a sweat-resistant formula that offers your horse 14-day, weather-resistant protection. Provides quick knockdown and repellency from biting and nuisance flies, gnats, and mosquitoes. Use on horses and ponies. Opti-Force contains 1% cypermethrin.
Spray or Wipe Application: Application should be liberal for best results.
For horse’s face, always apply as a wipe using a piece of clean, absorbent cloth, toweling (Turkish) or sponge. 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.
