About this product

An insecticidal plant spray for tomatoes and vegetables! Doktor Doom Spider Mite Knockout contains a high concentration of the naturally-occurring insecticide pyrethrin (0.20% formula). Effective indoors or out against aphids, spider mites, whiteflies, leafhoppers, Japanese beetles and much more. Unique nozzle sprays in all directions — even upside down for hard to reach areas. Safe to apply on food crops up to one day before harvest. Does NOT contain PBO. DIRECTIONS FOR USE: 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.
