If flies are bugging your horse， the Daily Dose Equine Bye Fly Horse Supplement offers a chemical-free fly control alternative. This feed-through system helps to repel flies from landing on your horse. After feeding， this supplement creates a 24-hour shield that tells flies， ticks， mosquitoes， gnats and no-see-ums to buzz off， rather than pestering your horse. It also kills adult flies， larvae and worms inside and outside of your horse. Its all-natural ingredients are safe and convenient， and you won’t have to worry about spraying down your horse every day. This supplement is highly palatable to appeal to even the pickiest eaters.
