Nematodes are microscopically small roundworms that specifically combat soil-dwelling pests such as fungus gnat larvae, black vine weevils or grubs.
Depending on the species, nematodes control, among other things, fungus gnat larvae, black vine weevils, grubs, mole crickets, garden chafer larvae, ants, flea beetles, snails and meadow crane flies.
No, nematodes are completely harmless to humans, pets, and plants. They specialize in specific pests and cause no harm.
The nematodes actively penetrate the pest larvae and release bacteria that kill the pest. The nematodes then multiply in the dead larvae.
The first effects usually appear after about 5–7 days. Complete control takes up to 3 weeks, depending on the pest and the severity of the infestation.
Yes, nematodes can be used regularly in vulnerable areas to prevent pests, especially if there are recurring problems with fungus gnats or grubs.
Nematodes are proving to be more resistant to heat than often assumed. Thanks to secure shipping packaging, our SF nematodes can easily survive unrefrigerated shipping for up to a week, even during the summer months. Therefore, we rely on environmentally friendly delivery without cooling pads and unnecessary packaging waste.
The nematodes will be delivered directly to your mailbox in an envelope . Even for orders containing other products, we ship our nematodes in a separate envelope. This ensures fast and secure delivery. For this reason, unfortunately, the nematodes cannot be delivered to packing stations .
Yes, ideally, nematodes should be applied immediately upon receipt. They can be stored in a refrigerator at 4–8°C for a few days (see packaging).
Our nematodes are enriched with a biological substrate that sometimes changes shape during transport and due to temperature fluctuations. This may make them appear mushy or clumpy, but they are still perfectly normal and fully functional .
If you add the product to water and stir well, you will notice that everything dissolves well and can be used without any problems.
Live beneficial insects are non-returnable. However, we're happy to help you with any problems.
