Prozap® War Paint Insecticidal Paste is specially formulated for full body fly control. It provides protection for horses against insects such as house flies, bot flies, black flies, face flies, horn flies, and stable flies. Contains three active ingredients that are relevant in targeting and killing flies. This insecticidal paste sticks and attaches to the hair when applied to horses and slowly releases the insecticide until it completely gives a full body control. It is proven to leave no visible negative effects on horses because, after two to three weeks of application, the paste turns powdery and falls off the horse' hair. For extended protection, apply to parts of the horse where fly conjugation occurs. Available in a convenient 96-gram tube.
