Thrips destroyer is a beneficial predatory mite Amblyseius cucumeris which controls the pest, Thrips, by attacking the larval stage of the insect before they have a chance to become adults. These beneficial predators work best when applied early to prevent thrips numbers from increasing. Thrips Destroyer is easy to use. Lightly mist leaves of the infected plant with water. Sprinkle granular bran mixture directly on the leaves or in a 5 ml (1 tsp) pile directly on soil or rock wool blocks, preferably beside the stem of the plant. 1 unit/tube contains 50,000 Amblyseius cucumeris and covers up to 100 medium plants.
