Selected Add-Ons

    A very effective control of two spotted spider mites and a variety of other spider mite species. 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. Wait 48 hours after application of a knockdown spray to release predatory mites.

    Phytoseiulus persimilis Mite Predator

    Phytoseiulus persimilis is a very effective control of two spotted spider mites and a variety of other spider mite species. 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. Phytoseiulus 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.

    Phytoseiulus 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 Conditions:

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

    The above conditions are optimum conditions and P. persimilis can be successful outside of those ranges. Keep in mind that cooler temperatures affect reproduction and development. At optimum temperatures, mite predators reproduce more quickly than predator mites; however, at warmer and cooler temperatures, pest mites reproduce more quickly. Predatory mites thrive in humid environments, while pest mites enjoy dry surroundings. Increase humidity by moistening soil or use a cool-mist vaporizer around plants in enclosed areas. See our Quick Pest Reference Guide for alternative predators suitable to your pest situation.

    Environment Release Rates
    Tomatoes/CucumbersUse 1 P. persimilis per plant, plus 1-2 per infested leaf.
    Greenhouse, Tropical & Garden Crops2,000 P. persimilis per 3,000 square feet.
    Bedding1,000 P. persimilis per 10,000 square feet.
    Growers5,000-20,000 P. persimilis per acre.

    Please Note: Release rates vary depending upon crop, infestation level and season of the year.

    Phytoseiulus persimilis are excellent for cold climates! Use preventatively as they over-winter and can be sustained on pollen. Release at the beginning and end of the season.

    Release immediately for best results. It is best to release Phytoseiulus persimilis in late evening on the day you receive them. Before releasing, gently rotate the jar to distribute the mites evenly within the carrier. Next, open the jar in the crop and gently tap the contents out of the jar as evenly as possible onto the foliage of the plants you wish to treat. Concentrate the bulk of them on or near the most heavily infested plants. In trees, sprinkle them into Dixie-like cups wedged into, or distribution boxes hung from, the branches. Leave the bottle in the treatment area for 24 hours after release to ensure all Phytoseiulus persimilis have exited.

    Due to its high reproduction rate, P. persimilis can exhaust its food supply and die out. Because of this, P. persimilis should be applied as an active control, not as a preventative measure. Repeated releases are recommended until all spider mite infestations have P. persimilis present.

    Since they are unable to sustain themselves without a mite population to feed on, look to N. fallacis for preventative applications as they can feed on pollen and small arthropods in the absence of mites.

    Environment:

    Outdoors, Crops, Nursery, Greenhouse, Grow Room, Hydroponics, Aquaponics, Pond & Environment, Interiorscapes, and Container Plants.

    Storage:

    If not releasing immediately, keep in a cool dark place out of direct sunlight. Do not refrigerate.

    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.
