Neoseiulus californicus

Neoseiulus Californicus: is a predatory mite that attacks two spotted spider mites, broad mites and cyclamen mites. They are a pinkish red color, obvious long legs, and they are oblong in shape. This form of predatory mite works great on crops such as cucumbers, tomatoes, strawberries, tropical plants, and greenhouse plants. They may also be used in gardens and orchards. The Californicus tends to be calmer than Mesoseiulus Longpipes and Phytoseiulus Persimilis which are both also predatory mites. However due to the Californicus being calmer they will survive longer under harsh conditions. Californicus prefer warm weather roughly 50 degrees to 95 degrees.  They can also survive very low temperatures for small periods of time and can survive in humidity ranging from 40% to 60%Life Cycle Stages: Egg, Larvae, Protonymph, Deutonymph and Adult. Sex Ratio – females predominant 4:1. Completes a generation in one to two weeks depending on temperature.Target Pest: Neoseiulus californicus attacks two spotted spider mites, broad mites, and cyclamen mites. Good for lower spider mite densities. Neoseiulus survives on pollen in the absence of prey. Effective on cyclamen, strawberry, corn, grapes, roses, vegetables, ornamentals and interiorscapes.

A natural way to Spider Mite control!

Due to a high demand, listening to our customers and research, we have developed a mixture of 3 Predatory Mites called “Special Blend”, normally consisting of an assortment of the following; M. longipes, N. californicus and P. persimilis. Special Blend is best used in unknown growing conditions. Our Special Blend takes the guess work out of which mite should be used in your Garden, Green House, or Grow Room. It has been proven to be very effective. You will see a mixture of bright reddish orange, colored mites with obvious long legs. These mites can tolerate temperatures up to 95°F., but do best in temperatures between 60° -85° F. They do well in humidities ranging from 50%-90%. To raise the humidity level you can lightly mist the plants or surrounding walkways. 

Our different Predatory Mite species are also sold separate for known growing conditions. All species are listed in our Spider Mite Control Page.


Release Instructions

  • Keep the package or vial in a cool location until you can release the predators. Ideal storage temperature is 50°F (10°C). But remember to release them as soon as possible.
  • You should be able to see the predatory mites with normal vision. Some may be seen in the cap after it is removed but, the easiest way is to sprinkle some of the corn cob meal on a white paper under a desk lamp or flashlight and watch them run on the paper.
  • Roll or tumble the vial to mix. Mist the leaves with water using a pump-spray bottle.  Remove the cap and sprinkle the contents on the infested areas of the plants.  The meal can be brushed off after an hour or so when the predators have left.  If you do not want the meal on the plants place paper or foil on plant to place material.
  • The predators will go to the underside of the leaf where the pest mites are usually found.
