Sachets are great preventative!

Had bad infestation of spider mites so used Pytoseiulus Persimilis along with swirisky and californicus sachets! Be patient and reapply Persimilis if required! I get new sachets every 4 to 5 weeks! The tiny spider mite outbreaks disapear in aweek or so by are occurring with less frequency as each month goes by! Yay Growliv!


Despite having them in optimal conditions with lots of food available they, seem to have disappeared? and done little to nothing to suppress or end the pests. Unlike your competitor's product, these mites were ineffective.

Thanks for your feedback. Sachets are meant for preventative control only, before pests arrive. The number of mites released from sachets is not high enough to keep up with the fast life cycle of pests. It is best to use this product with a more aggressive predator (OriLiv for thrips or PersiLiv for spidermites) to suppress and prevent the pests. Send us an email with the pest issue you are trying to manage and we will be happy to recommend a product that will work best for you.


Great fast service, well packed products.
