Equisect Fly Repellent is not labeled for use on donkeys. However, Absorbine UltraShield Red Insecticide and Repellent Spray is labeled for use on donkeys. This product may be applied either as a wipe or as a spray. When applying as a wipe, or on the animal’s face, always use a soft cloth. When possible, first brush animal to remove excess dirt and dust. Spray or wipe the animal’s entire body while brushing against the lay of the coat to ensure adequate coverage. Avoid getting spray into animal’s eyes, nose or mouth. Do not wet skin, or apply to the point of dripping or exceed two ounces per application. Reapply every 7 days under normal conditions. Reapply each time the animal is washed or exposed to heavy rain for best results. When possible, after application, brush thoroughly to bring out bright sheen on the coat.
