This ready-to-use product provides fly protection and imparts a high sheen to the hair when brushed out. Effective protection results from only 1 to 2 ounces per head. Apply in either a fine spray mist or by using a soft cloth to coat the animal's body. Wipe N' Spray is citronella scented and contains lanolin as a coat conditioner. It has been proven effective on biting flies, mosquitoes, gnats, fleas and ticks.
