When to use Spidend?

How does Spidend work?

After emerging from the pupa, adult gall-midges actively search for spider mite colonies and deposit eggs next to the spider mites. Once emerged, the larvae feed on the spider mites.

Application Spidend

- Protect against direct sunlight and water
- Leave the cup in place for at least two weeks


Storage time after receipt: 1-2 days.
Storage temperature: 12-14°C/54-57°F.
Storage conditions: In the dark.


The dosage of Spidend depends on climate, crop and spider mite density and should always be adjusted to the particular situation. Start introduction as soon as the first spider mites are detected in the crop. Introduction rates typically range from 0.25-25 per m2/release. Releases should be repeated at least 3 times at weekly intervals, or until the pest is controlled. Consult a Koppert advisor or a recognized distributor of Koppert products for advice on the best strategy for your situation.
