Amblyseius Swirski is an amazing predator of Thrips and Whitefly as well as Broad and Russet mites. They can consume up to 10 thrips or Whitefly larva or 20 Whitefly eggs a day. Population development begins when temperatures rise above 68-72 F, and the beneficial will hunt and develop to 95 F. Due to their ability to feed on pollen and aggressive behavior, they make an excellent choice as a preventative or curative beneficial.

Working conditions
Temperature: 68-95 F
Humidity: 60%+

*Application rates can vary depending on actual conditions.

  • Sachets: Hang sachets on plant midway up the trunk of the plant, close in to the center. Sachets already have an exit hole for the mites. There is no need to open them. 1-2 sachets per 10 sq ft is recommended for preventative maintenance.
  • Loose Mites: Let the predatory mites come to room temperature with container on its’ side. Roll or tip, depending on whether a bottle or bag, container back and forth a few times to gently mix contents and then tap out of container onto the affected foliage for best results. When left in one position for too long, predatory mites will gather at the top, leaving the bottom with a much lower proportion of mites, so rotating the container as it is being tapped out is suggested. Alternatively, contents can be placed in Bugboxes and hung on plants.
