Application Cryptobug-L

  • Apply material on rock wool slabs for general introduction, or in Diboxes close to or at a hotspot
  • Place among infected leaves
  • Apply in the evening

Best working conditions Cryptobug-L

The minimum temperature for successful use of Cryptobug is 16°C/60.8°F. However, Cryptolaemus favors high temperatures and relative humidity. Therefore, Cryptobug is at its most effective at temperatures between 25°C/77°F and 28°C/82.4°F. Beetles are more mobile than larvae, thus more useful for general introductions or in high crops. When possible use larvae for hotspot treatments.


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 Cryptobug-L, please follow the instructions below. Koppert B.V. is not liable for any loss of quality if the product is stored for longer and/or under different conditions than recommended.

  • Storage after receipt: 1 day
  • Storage temperature: 10-15°C/50-59°F
