  • Galendromus occidentalis, or the Western Predatory Mite, is a primary biological control agent of pest mites and is used to control mites outdoors for crops, orchards, vineyards, nurseries, and indoors for greenhouses, growing rooms, hydroponics, aquaponics, interiorscapes, and container plants. Adults are pear shaped and white, but once they start feeding they take on the coloration of their prey, usually red or brown. Best used before pest mite webbing occurs. Once pest mites are established, a much greater amount of Galendromus is required to be effective.

    Galendromus can tolerate higher temperatures and lower humidity than other predatory mites and can thrive in hot, dry climates. These biocontrol agents are packaged on corn grits or vermiculite.

  • 0.5-1.5 per square foot, 2,000 - 5,000/acre biweekly for 2-3 applications. 
  • Lay bottle on side upon receipt to evenly distribute mites. For best results, mist the foliage prior to application so carrier will cling. Gently shake predator and carrier onto the foliage of infested crops. Hold a paper plate under leaves to catch what falls through. This natural enemy will migrate off carrier immediately and seek out prey. Shipped fresh and quality guaranteed.
