Directions For Use

It is a violation of Federal law to use this product in a manner inconsistent with its labeling.

READ THE LABEL: Read the entire label and follow all use directions, use restrictions and precautions.


Do not apply this product with a sponge. Do not use this product on horses intended for human food. Do not apply to a wet animal since the product will not adhere to moist surfaces. War Paint, once applied to the hair of the horse, cannot be wiped off. Therefore, it should not be used within one to two weeks of an event or show in which the presence of small amounts of War Paint of the horse’s coat would have an adverse effect on the horse’s appearance. As with any product certain individual horses may be sensitive to one or more of the ingredients in War Paint. If local irritation should occur, discontinue use. If irritation persists, discontinue use, was area and consult a veterinarian.

Product Information

It requires very small amounts of War Paint to kill and repel flies. Small amounts of War Paint are placed on the horse only where flies tend to congregate. War Paint, when applied to the horse, attaches to the hair of the horse and slowly releases the insecticide over a period of weeks. Full body fly control does not usually occur until 1 to 2 days after application.

The reason for this is it takes time for the formulation to release the insecticide onto the horse’s hair. Because War Paint is not only and insecticide, but also an effective repellent, you will notice that in the case of face fly activity, the repellent activity of the product will be apparent within hours if not immediately after application. After a period of one to two weeks, as the insecticide is released onto the horse’s hair, you will find that War Paint becomes powdery and will fall off the horse’s hair leaving no adverse effects on the horse’s appearance.

Full Body Fly Control:

Adult horses: For the treatment of pastured horses, it is recommended that a full application be applied as a single treatment. This should provide adequate fly control for approximately one week on pastured horses.

Apply one (1) gram under each eye, two (2) grams on withers and (2) gram on each leg below the hock or knee - 12 grams total as a single treatment. DO NOT REPEAT TREATMENT FOR SEVEN (7) DAYS.

Application Techniques

FACE FLIES: Turn the applicator wheel until the gel is seen at the top of the applicator then continue turning 1/8 of a turn to place on (1) gram of War Paint on top of the applicator. Then while holding the applicator length wise, apply under the eye along the lower lid, close to the lid margin. Do not apply directly into the eye. Make a 1 inch wide stripe along the entire lower lid from corner to corner. For maximum Face Fly control, it is very important to place the product around the inside corner of the eye where the top and bottom lids meet. This is the area where tearing occurs due to fly irritation and where face flies congregate to feed. Repeat the application to the other eye. A 1 - inch stripe under each eye will apply 2 grams of War Paint to the face.


Turn the applicator wheel 1/4 turn to place 2 grams of War Paint on the top of the applicator. Then apply a 1 by 4 inch stripe under the horse’s mane on the withers. Place the product far enough up the withers so the product will not be under the saddle or blanket if the horse is to be ridden.


Apply a 1 by 4 inch stripe to each leg. Turn the applicator wheel 1/4 turn to place 2 grams of War Paint on the top of the applicator. Then apply the material to the front of the house’s leg for inches below the knee or hock. Touch the applicator to the spot to be treated and move the applicator in the narrow direction up the horse’s leg four inches toward the knee or hock. Smooth out the material using the top of the applicator to a 1 inch wide by 4 inch long stripe on each leg.


To kill and repel bot flies during the egg laying season, War Paint should be applied over the bot eggs already on the horse. A four inch by one inch wide strip should be painted over the area where the bot eggs are attached. This should be done instead of applying War Paint to the front of the legs, since this application will also control stable files and bot flies usually lay their eggs on the sides of the horse’s legs.


The same technique for applying War Paint can be used on foals, except only 1/2 of the adult amount should be used - 6 grams total. Since the foal’s eyes are smaller than adult horses, a one inch wide stripe under each eye of a foal will apply on 1/2 gram of War Paint under each eye. When applying to the foal’s withers and legs, make the application stripe only 1 inch wide by 2 inches long instead of the 4 inch long stripe used on adult horses. This will insure that a foal will receive on-half of the adult horse dose. Remember, a 1/8 turn of the applicator wheel will dispense one gram of War Paint on the top of the applicator.


For horses that are to be ridden and handled frequently, lesser amounts of War Paint be applied more frequently are a better choice. Lesser amounts of War Paint applied discreetly and prudently to the horse can provide more effective local fly control for several days to a week. If this technique is used, remember not to apply more than 12 grams of War Paint to a horse in any 7 day period. See application technique and illustrations.
