SPIDEX (Phytoseiulus persimilis) targets the two spotted spider mite (Tetranychus urticae) in all stages, preferring younger stages. This predatory mite can, reportedly, only survive on two spotted spider mites (Tetranychus spp.), IE: reproduce at a sustainable rate. 


  • turn and shake the bottle gently before use
  • sprinkle material on leaves or pour into application boxes (DIBOX)

Suggested Application Rates: The introduction rates of this product should be adjusted to the mode of action of the product and the results that can be expected in the crop where the product is applied. Your local consultant will be able to advise you further.


Environmental conditions: Relative humidity should be greater than 75% and the temperature above 20°C/68°F for some hours of the day. Phytoseiulus persimilis does not enter diapause.


  • Adults: bright red, very active, spherical, stands high on its legs
  • Eggs: oblong, first pink and transparent, later on darker, twice as big as spider mite eggs
  • Larvae/nymphs: pale to light red

Mode of action:  Adult predatory mites and nymphs search actively for their prey and suck them dry.

Visual effect: Adult red spider mites that have been eaten change color from brown to black (in tomato) and can be identified as tiny black dots on the leaves. This should not be confused with living, light-brown to dark-red spider mites.

Frequently asked questions:

  • Light infestations can be controlled within 2-3 weeks. Repeat releases every 7-14 days until control is achieved. Call to set up a customized weekly or bi-weekly ship program.
  • Predatory mites thrive in humid environments, whereas pest mites enjoy dry surroundings. Increase humidity by moistening soil or use a cool-mist vaporizer around plants in enclosed areas.
  • For heavy infestations, remove the most affected plants and use a knock-down spray. Release predatory mites after 48 hours of application of a knock-down spray.
