Neoseiulus californicus is a predatory mite that belongs to the Phytoseiidae family and is of the Arachnida Class.

Target Pests

Two spotted spider mite (Tetranychus urticae), fruit spider mite (Panonychus ulmi), citrus red mite (Panonynchus citri), begonia mite (Tarsonemus pallidus) and broad mite (Polyphagotarsonemus latus).


Citrus, grapes, raspberries, strawberries  and several vegetable crops.


Neoseiulus californicus are translucent and range in color from pale orange to peach. The nymphs resemble the adults except that they are smaller and cannot reproduce. Their eggs are oblong, transparent and white to dirty-white in color. Adult predatory mites, nymphs and larvae actively search for their prey and suck them empty. All stages of Neoseiulus californicus prefer to eat younger stages of host mites and adult females can consume fifteen to twenty spider mite eggs per day. Neoseiulus californicus can also feed and survive on Thrips and can survive for up to 3 – 4 weeks without food and therefore very good for prophylactic treatments and maintaining low populations of Red Mite and Red spider mite. Neoseiulus californicus tolerates high temperatures and low humidity levels.

  • Spread the content of the bottle as evenly as possible throughout the orchard.
  • During hot days, releases should be done during early morning or late afternoons.
  • First application is between 50,000 to 100,000 mites per Ha. Additional quantities might be needed according to the infestation level and scouting information.
  • Application should occur as early as possible in the season, however generally, releases start from January to March, after harsh chemical sprays

Follow Up

About 2 to 3 weeks after releases, BioCalifornicus mites will be observed in the proximity of their prey mites. Reduction in pest mite population will be noted after establishment of the BioCalifornicus. Dead prey mite eggs and nymphs will also be observed.
