SMITE is extremely effective and kills naturally on contact. It contains oils produced by cold-pressed extraction of naturally grown Geranium, Peppermint, Cottonseed, and Rosemary. Under warm conditions, SMITE will naturally biodegrade leaving minimal residue.Spider mites are known to feed on several hundred species of plants. A single mature female can spawn a million mites in one month. Their accelerated reproductive rates allow spider mites to adapt quickly and develop resistance to normal pesticides. SMITE kills on contact by blocking the breathing holes, resulting in death by suffocation. SMITE causes reproductive disruption among female spider mites not initially contacted by the spray. This leads to infertility, eggs that do not hatch or mites that do not develop to an adult stage. Dilute 1 fl. oz. of SMITE per 1 gallon of water. SMITE should be foliar sprayed directly onto the insects and areas infested by the insects. To reduce the chance of burning, raise grow lamps and do not use directly under intense lighting. If outdoors, avoid applying during peak sun by making application during the morning or evening. Apply to infested areas 2 - 4 times every 5 - 7 days apart. To prevent insect infestation, apply SMITE every 14 days. SMITE is FIFRA 25(b) exempt.
