Prozap Insectrin Permethrin Dust contains 0.25% permethrin. Used for fly and lice control on cattle and horses; lice control on swine; and mite control on poultry.
Beef and Dairy Cattle and Horses:
Horn flies, lice, face flies: Place Prozap Insectrin Dust in a dust bag suspended in areas frequented by cattle or in gateways or lanes through which the animals must pass daily for water, feed, or minerals. Bags may also be placed in loafing sheds or in front of mineral feeders. For dairy cows, dust bags may be suspended in the exit through which the cows leave the milking barn. The bags should hang 4 to 6 inches below the back line of the cattle. For reduction of face flies, bags must be located so animals will be forced to use them daily and hung at a height so that the face is dusted.
Horn flies, lice: Apply 2 oz. of dust per animal over head, neck, shoulders, back, and legs.
Lice: Apply 1 oz. per head as a uniform coat to the head, shoulder, and back. Do not apply more often than once every 10 days. In severe infestation, both animals and the bedding may be treated.
Northern fowl mites, apply at a rate of 1 lb. per 100 birds.
