When to use Scia-Rid?

Use Scia-Rid for the biological control of larvae of mushroom flies. It has also effect on other species of flies (e.g. Phorid flies).

How does Scia-Rid work?

After application, the nematodes actively search for their prey and penetrate them. The nematodes feed on the contents of the prey, excreting specific bacteria from their digestive tracts as they do so. These bacteria convert host tissue into products that the nematodes can easily ingest. The larvae die within a few days.
