How it works

Mode of action

Predatory mites multiply in the sachet and disperse into the crop over a period of several weeks. They pierce the prey with their sucking mouthparts and suck out the contents.

Directions for use


  • Hang sachets in sheltered locations in the crop, not exposed to direct sunlight
  • Sachets already have an exit hole
  • Hold sachets by the cardboard strip at the top, to avoid damaging the predatory mites


The dosage of Spidex Vital Plus depends on climate, crop and pest density and should always be adjusted to the particular situation. Spidex Vital Plus should be introduced in and around a hotspot. Release should be repeated biweekly if the pest is not controlled. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
