Neoseiulus (= Amblyseius) californicus is an oblong, tiny predatory mite that feeds on a variety of prey and is useful in prevention, control and management of infestations of various spider mite species. It can also be used as a preventative control of broad mites, cyclamen mites, and some russet mite species. Since they are slower feeders than other mite predators (P. persimilis, N. fallacis), N. californicus should be used in conjunction with other suitable beneficial insects in the presence of large pest populations.

N. californicus mite predators are pear-shaped relative to pest mites and have a creamy color (more opaque than pest mites). Their slow feeding habits make them effective against low mite populations and when used preventatively. N. californicus are known to be effective on the west coast and in the southeastern United States due to suitable temperature and humidity levels in those regions. Use on crops including cucumbers, tomatoes, strawberries, tropical foliage plants, and greenhouse roses. Suitable environments for release are gardens, grow rooms, fields, orchards and greenhouses.

Preferred Food: Two-spotted spider mites and many other mite species. Reproduction rates are best when spider mites are the primary food source. These predatory mites consume egg, nymph and adult stages of pest mites.

Optimum Conditions: 50-105°F, 40-60% RH

Significantly cooler and warmer temperatures will slow and/or inhibit reproduction and development. Higher humidity is generally necessary with higher temperatures; however, N. californicus can persist in low humidity environments with limited food sources. The slower pace that these predatory mites feed at (5 mites per day) and their ability to sustain themselves on pollen allows them to survive longer in low pest populations. A full life cycle for N. californicus lasts between one to two weeks and is significantly influenced by temperature.

Release Rates: Some crops, including tomatoes & other highly resinous crops, require higher release rates.

  • 1-4 mites per plant (roughly 1,000-4,000 per 1,000 square feet) or 1-2 per square foot in greenhouses, biweekly, 2-3 times
  • 5,000-20,000 per acre depending on infestation levels, biweekly, 2-3 times
  • Mini-Sachets - 1-2 sachets per plant depending on infestation levels. Repeat applications every 4 weeks.

PLEASE NOTE: All Mite Predators require additional processing time due to rearing and collection times. Additional information can be found on the Shipping Tab to identify the earliest shipment date. If you have questions about shipment dates, orders can be placed with our sales representatives at 1-800-827-2847.
