Effective control of two spotted spider mites with Phytoseiulus persimilis PLUS in convenient sachets!
Introduce Phytoseiulus persimilis PLUS sachets at first sign of mite infestation. Once leaf damage is serious, more than 4 mites per leaf, achieving control is more difficult. For heavy infestations, remove the most affected plants and use a knock-down spray (see Neem Oil). Wait 48 hours after application of a knockdown spray to release predatory mites.
Controlled Release: For preventative use, Controlled Release sachet mites emerge 8-12 days after application.
Rapid Release: Mites emerge 3-5 days after application of Rapid Release sachets.
P. persimilis PLUS are reared in an innovative way to include mobile mites (adults and juveniles) PLUS eggs. Unlike traditional P. persimilis, P. persimilis PLUS arrives pale and changes to orange/red after predation on pest mites begin.
Optimum Temperature and Humidity: 68-90°F (20-27°C) and 60-90% Relative Humidity
These conditions are optimal and P. persimilis can be successful outside of those ranges; however, reproduction, development and activity levels can all be reduced. Increase humidity by moistening soil or use a cool-mist vaporizer around plants in enclosed areas.

Open the shipping box of the sachets in the crop. Separate sachets by tearing along perforations. Hang sachets inside plant canopy where possible with emergence hole on the underside. Apply when crop is dry to maximize hatch rates. Do not hang where sachets will be directly exposed to intense sunlight or near heating pipes.

Warning & Toxicities: Do not release P. persimilis in areas where A. cucumeris are being used. A. cucumeris feed on spider mite eggs, limiting the food supply for immature Persimilis. See our Quick Pest Reference Guide for alternative predators suitable to your pest situation.
Shelf Life: Use within 18 hours of receipt.
Life Cycle: The complete P. persimilis life cycle varies based on temperature with higher temperatures accelerating the process and cooler temperatures slowing it down. At 86°F, maturity is reached after 5 days, while maturity is reached in as many as 25 days at 59°F. The sex ratio for P. persimilis is 4:1 female to male with females laying 2-3 eggs per day.
Eggs hatch in 2-3 days, but newly hatched juveniles do not feed. Later immature stages and adults feed on all stages of mites with each predator consuming 5-30 prey per day.
