Farnam - Bronco Horse Fly Spray
Description
TL;DR: Farnam Bronco Horse Fly Spray is a ready-to-use, water-based insect repellent that kills and repels flies, mosquitoes, gnats, and ticks on horses, ponies, and foals. It's a non-oily, citronella-scented formula built for daily use in the barn or pasture.
Biting insects make horses restless, rub-prone, and miserable during warm months. Bronco is a straightforward, spray-and-go defence you can apply before turnout, trail rides, or barn chores.
What does Bronco Fly Spray do?
It kills and repels a broad range of pasture and stable pests — flies, lice, mosquitoes, gnats, fleas, and ticks. The water-based formula dries without leaving an oily film, so it won't stain tack or dull coat shine.
