Always apply in the dark late at night or early in the morning — NEVER in direct sunlight or with HID lights on. Water plants before application.
Be careful to remove any webbing that you see by hand prior to treatment — webs work as an umbrella and prevent sprays from getting through to the plant.
Spray the underside of the foliage from a distance of 2-3 feet away from the plant. Spider Mite Knockout is equipped with a special spray valve that sprays upside down.
Spray with short bursts 1-2 seconds at a time — a light mist is all that is required. Do NOT soak foliage.
