Perfect application for face flies! War Paint®requires very small amounts to kill and repel flies. Small amounts of War Paint are applied to your horse where flies tend to congregate. War Paint attaches to the horse's hair and slowly releases the insecticide over a period of time. Full body fly control does not usually occur until 1 to 2 days after the application.
Because War Paint is not only an insecticide that kills, but also an effective repellent. The repellent will be apparent within hours if not immediately after application.
After a period of one to two weeks, as the insecticide is released onto the horse's hair, you will find that War Paint becomes powdery and will fall off the horse's hair leaving no adverse effects on the horse's appearance.
