When to use Spidend?

Use Spidend for biological control of various species of spider mites. Spidend is recommended especially when spider mite occurs in colonies/hotspots.

How does Spidend work?

Adult gall-midges actively search for spider mite colonies and deposit eggs next to the spider mites. It takes one week for the eggs to develop to mature larvae. Once hatched, the larvae feed on spider mite eggs.

How to use Spidend

Application Spidend

  • Make a hole in the lid and put the can on the rock wool slab or directly on the soil
  • Protect against direct sunlight and water
  • Leave the can in place for at least two weeks
  • Use the peel-off label to mark where the product has been introduced

Feltiella acarisuga should always be used in combination with the predatory mite Phytoseiulus persimilis (Spidex).
