KattleGuard™ is the leading fly and lice control, helping control filth and biting flies, mosquitoes, ticks and lice. It’s easy-to-use motion activated, automatic system is safe, shutting off to control waste and not overdosing the animal. Micro-layering kills flies and protects cows by applying a fine mist to the cow’s outer coat, cutting down on chemicals and boosting effectiveness. Flies land on the coat and die quickly. Little, if any, chemical reaches the skin – leaving the maximum dose on the hair surface for flies.
