Made to annihilate flies, ticks, and mosquitoes with brand-new, EPA-approved ingredients never before used in equine care.

Endure^® Gold Killer Fly & Mosquito Control represents a significant advancement in the category as the first EPA-approved fly spray for horses to feature acetamiprid and etofenprox, two new killer active ingredients, never before used in equine fly control. The formula delivers a new, field-tested mode of action designed to help manage resistant insect pests while providing fast knockdown and extended protection.

“We’re incredibly excited to launch Endure Gold, a groundbreaking new fly spray that brings an advanced, next-level formula to the market,” said Kevin Tompkins, Vice President & General Manager, Equine at Central Garden & Pet. “With six active ingredients—including two that have never been used in horse products—Endure Gold delivers a superior experience horse owners are going to love. It’s a powerful example of Farnam’s ongoing commitment to innovation and our promise to make everything for the ride better for horse owners.”

Designed for a New Era of Fly Control

Backed by science and developed at Farnam’s leading Research and Development facility, Endure^® Gold Killer Fly & Mosquito Control supports a smarter, more strategic approach to equine fly control that prioritizes effectiveness over time, not just short-term relief.

“Applying the same fly spray over and over can lead to insecticide resistance in pest populations,” said Chris Holderman, Ph.D., Senior Manager, Product Development at Central Life Sciences. “Endure Gold was developed to be a rotational product, one that’s included in an Integrated Pest Management plan. Rotating modes of action for pest control slows down development of insecticide resistance.”

By introducing acetamiprid—a modern ingredient with a new mode of action—and etofenprox, an ingredient exclusive to Farnam for use on horses, Endure^® Gold Killer Fly & Mosquito Control helps horse owners reduce reliance on the same chemistry season after season while fitting easily into rotational fly control programs. Approved for use on horses, ponies, foals, miniature horses, donkeys and mules, it offers a flexible, long-lasting solution for all equines.

Innovation Rooted in Experience

Endure^® Gold Killer Fly & Mosquito Control will arrive on retail shelves and across eCommerce channels nationwide as peak fly season begins.

As Farnam prepares to celebrate its 80th anniversary, the introduction of Endure^® Gold Killer Fly & Mosquito Control underscores the brand’s commitment to progress, combining decades of equine expertise with modern science to deliver innovative solutions that help keep horses comfortable, protected, and performing at their best.
