What’s in the CaliLiv Sachets?

Predator: Amblyseius californicus – each sachets contain about 250 mites of all life stages.

How to use A. californicus sachets:

  • For best results place sachet inside the plant canopy where humidity is higher, and temps are cooler than the ambient climate.
  • Don’t hang sachets in areas with strong winds from ventilators/fans
  • Avoid direct sunlight, it dries the sachets microenvironment and creates excessive heat which can kill the mites quickly.
  • Don't make the release hole bigger for faster release, this will reduce the moisture in the sachet and shorten its life span significantly. 

Can you store A. californicus sachets?

We recommend releasing the predators immediately upon arrival. 

If storage is necessary sachets can be stored for 1-2 days at room temperature in a dark, humid place (RH 60% or more). Avoid any contact with direct sunlight. 

WARNING: Storing predatory mite sachets accumulates Co2 overtime, always store in a well-ventilated place.

How to promote establishment?

To achieve optimal results the most important factor is humidity. If there isn’t enough moisture in the sachet, the food chain will end and starve the predatory mites. The predatory mite eggs and larval stages are also very sensitive to low humidity, constant dry conditions will significantly decrease the egg hatchability. The relative humidity for sachets needs to be at least 60% or higher.

How to check if my sachets are still producing predatory mites?

After week 4 you should check if your sachets are still producing predatory mites or if it’s time to replace them. To check, open up a few sachets from different areas in the greenhouse. Use a 10x lense to check for fast moving mites. If you don’t see any predatory mites, it’s time for a replacement.

How often should you be reordering?

Sachets normally last 4-6 weeks before requiring a replacement.
