Swirski Ulti-Mite contains the predatory mite Amblyseius swirskii, a highly effective natural enemy of thrips, whitefly, and tarsonemid mites, targeting young larvae of various thrips species and eggs and larvae of whitefly. This polyphagous predator establishes rapidly in a wide range of protected cropping systems, including glasshouses and polytunnels, and is a warm active temperature predator with an optimum range of 20–32 °C. A. swirskii moves very rapidly and when applied preventatively or at the first signs of pest presence, the species maintains stable populations by feeding on pollen and small arthropods, ensuring continuous pest suppression throughout the crop cycle.

With its continuous-release sachets, Swirski Ulti-Mite ensures long-lasting protection and consistent predator establishment over a number of weeks.

Please note, Amblyseius swirskii is sold under licence in the UK.
