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.
This Product Controls These Pests or Diseases: Brown Almond Mite (Bryobia rubrioculus), Spider Mite (Mult), Two-Spotted Spider Mite (Tetranychus urticae), Cyclamen Mite (Phytonemus pallidus), Broad Mite (Polyphagotarsonemus latus), Russet Mites
N. californicus are effective mite predators and control spider mites, broad mites, cyclamen mites and some species of russet mites. Release instructions can be found below. If you are a first time user of N. californicus mite predators, please call us at 1-800-827-2847 to walk through application instructions and best practices.
Shaker Tube Application: Shake small quantities of predatory mites onto crop where pest pressure is heaviest. Immediately before opening, gently rotate the container to distribute mites evenly throughout the carrier material and continue rotating during application, keeping material mixed. Keep rotating the bottle slowly as you disperse the predators.
Mini-Sachet Application: Place sachets within crop canopy using one to two sachets per plant. Apply when crop is dry to maximize hatch rates. Each sachet contains a mixture of immature and adult mite predators to ensure continued emergence over 4-6 weeks.
Viability Note: If you plan to check for viability, please do so upon receipt and prior to releasing the beneficial insects. Many predators and parasites are small and can be difficult to spot once released. If you believe there are issues with viability, please contact us at 1-800-827-2847 or email@example.com.

Owner Response: Fantastic! Most of our mite predators go to indoor growing environments, so it is great to get feedback when they are used differently. Thanks for getting back!
