Mite Predator, Phytoseiulus persimilis - 4000

Effective control of two spotted spider mites! Release Phytoseiulus persimilis 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. P. persimilis are red in color relative to the pest mites they feed on and are best used to combat active mite populations. P. persimilis will leave the area in search of alternative food sources if pest levels drop too low.

P. persimilis consume egg, nymph and adult stages of pest mites. Light infestations can be controlled within 2-3 weeks. Repeat releases every 7-14 days until control is achieved.

Optimum Temperature and Humidity: 68-90°F (20-27°C) and 60-90% Relative Humidity

The above 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.

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