How the unique chemistry in Outlaw outperforms the rest
Outlaw Equine Fly Spray has six times more cypermethrin than the leading brand
With just a few exceptions, most equine fly sprays on the market today are based on permethrin and/or pyrethrin. While those formulations were considered revolutionary in their day, now there’s something better: cypermethrin.
In clinical trials between Outlaw Equine Fly Spray, Farnam® Endure™ and a control formula, new Outlaw Equine Fly Spray with cypermethrin repelled biting flies and other pests with 90% efficacy for a full two weeks, while Endure showed similar performance for only 9 days. That’s because although both Endure and Outlaw contain the breakthrough chemical cypermethrin, Outlaw Equine Fly Spray contains six times as much cypermethrin as Endure for the best fly protection you can buy.
Protection from West Nile Virus-bearing mosquitoes
In our tests, both the Endure Spray and the Outlaw Equine Fly Spray provided good protection against mosquitoes for at least seven days after application, but the Outlaw Equine Fly Spray showed higher potency against nuisance insects and gnats on day 14 and continued protection against house flies and stable flies on day 22.
Additionally, although all three sprays repelled the Culex mosquito associated with West Nile Virus, on day 14 the Outlaw Equine Fly Spray worked the best. When horses were sprayed a second time after day 14, the percentage of mosquitoes repelled 22 days later was much higher for horses treated with Outlaw Equine Fly Spray.
That’s especially important today when the potentially deadly West Nile Virus (WNV) has spread to virtually all corners of the United States. According to the USDA, one horse in three diagnosed with WNV either dies or is euthanized because there is no treatment or cure.
