This ointment is designed for use on dogs, horses and ponies to help manage fly activity around wounds, sores, scratches and other sensitive spots. The formula combines piperonyl butoxide, pyrethrins and di-n-propyl isocinchomeronate to repel and kill house flies, stable flies, face flies and horn flies on contact. It is applied topically to the area in and around a wound or sore rather than saturating the wound itself, and daily reapplication helps maintain coverage. The ointment comes packaged in a lightweight container designed for barn, kennel or tack room storage. Hands should be washed thoroughly after each application. The product is intended for animals 12 weeks of age or older, and a veterinarian should be consulted before use on debilitated, aged, pregnant, nursing or medicated animals.
