Directions For Use

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

For use on Dairy Cattle, Beef Cattle and Horses.

Livestock Spray is a dual-purpose formulation designed to protect dairy cattle, beef cattle, and horses from the attacks of biting flies, in the barn and on the pasture, as well as to function as an effective space spray for quick knockdown and kill of houseflies in the barn and milk room.

ANIMAL SPRAY-Dairy Cattle, Beef Cattle, Horses: To protect animals against the attacks of horseflies, stable flies, horn flies, mosquitoes and gnats, apply just enough to wet the ends of the hairs but not enough to soak the hide. One to two ounces is sufficient to treat an adult cow. Apply once daily, preferably in the morning. Repeat at daily intervals or as necessary for continued protection.

SPACE SPRAY-Barn and Milk room: To attain quick knockdown and kill of flies, gnats and mosquitoes in enclosed spaces, spray toward the ceiling and corners until the space is filled with a light mist. For best results, close all windows and doors prior to spraying and keep them closed for 10 to 15 minutes after spraying. Cover milking utensils and milk to prevent contamination from spray and falling insects. Sweep up and destroy fallen insects.

NOTE: Do not remain in treated areas and ventilate the area after treatment is completed.
