Best working conditions Swirski-Mite

The predatory mite is not susceptible to diapause and therefore can also be introduced during the winter time. It is tolerant to high temperatures; a swirskii population starts to develop when the temperatures during the day regularly exceed 20-22°C.


Biological beneficials have a very short life expectancy and therefore need to be introduced into the crop as soon as possible after receipt. Failure to do so can have a negative impact on their quality. In case you do need to store Swirski-Mite, please follow the instructions below. Koppert B.V. is not liable for any loss of quality if the product is stored for longer than recommended and/or under incorrect conditions.

  • Storage after receipt: 1-2 days
  • Storage temperature: 12-14°C/50-60°F
  • In the dark
  • Provide ventilation to prevent CO2 accumulation


The information given below is merely indicative. Tailored advice can be provided if information is available on the local factors that need to be taken into account, such as the crop, the climate conditions and the level of infestation. For the correct approach, please consult a Koppert specialist or a recognized distributor of Koppert products.
