Apply undiluted as a surface spray. Remove animals prior to treatment. Allow treated surfaces to dry before allowing animals back into quarters treated with this product. Do not apply directly to any animals destined for milking or slaughter. Surface Spraying: Use a good sprayer adjusted to deliver a coarse wet spray. Apply as a coarse wet spray using 1 pint per 1,000 sq. ft. Direct the spray wherever flies congregate or alight, until surfaces are moistened. Treat around doorways, feed storage rooms, alleyways and windowsills. Spray around outside of door facings and screens to render area unattractive to insects. This helps to repel insects and prevent entrance into building.

Do not contaminate water, feed or foodstuffs, milk or milking utensils. Repeat treatment daily, or at intervals needed to give adequate protection.

FLEAS AND TICKS ON DOGS: Start spraying at the animal’s head avoiding the eyes, nose and mouth as you spray. Make sure the animal’s entire body is covered including the legs, underbody and tail.
