Bronco E Horse Fly Spray Plus Citronella is a barn essential for horses, dogs, and the spaces they share. This water-based formula kills and repels six types of flies (stable, horse, face, deer, house, and horn) plus mosquitoes, gnats, ticks, deer ticks, lice, fleas, and chiggers. Safe for horses, ponies, and foals, it also works as a premises spray in barns, stalls, trailers, and kennels, and is safe for use on dogs. The non-oily formula won't leave greasy residue on coats, tack, or surfaces. The fresh citronella scent is noticeable but not overpowering, and works alongside the active ingredients (permethrin, prallethrin, and piperonyl butoxide) to help deter insects from the area. Apply as a light mist for full-body coverage or use with a cloth or sponge for sensitive areas like the face, ears, and muzzle.
