Equi-Spot® Spot-On Fly Control is easy to apply and contains 45% Permethrin to effectively protect horses from pests for 14 days. The water- and sweat-resistant formula kills and repels house flies, stable flies, face flies, horn flies, gnats, and ticks on horses. This spot-on treatment is ideal for pastured horses, as the treatment stays on longer than sprays. There are three defense zones that need to be covered to effectively apply this fly control treatment. The chest, head and neck are defense zone 1, the sides of your horse's body are defense zone 2, and the legs or your horse are defense zone 3 (video below).
Note: Safe enough for horses as young as 12 weeks. One easy to apply 10 mL applicator lasts for 14 days. One 3-pk lasts 6 weeks.
