Biological plant protection
With Neudorff’s new nematodes now available straight from the shelf without the need for refrigeration, this natural form of pest control has never been more accessible to UK gardeners, but what are the benefits and how do nematodes work?
What are beneficial nematodes?
Nematodes are very small, white to colourless roundworms, which can be found in almost every ecosystem on earth. Some species of these tiny creatures are predatory and can be used in horticulture for the control of many soil bourne pests.
How do nematodes work?
Nematodes kill larval pests, thereby stopping the damage they cause to plants and lawns. They first enter the pest larvae and inject it with bacteria, causing death. Nematodes will then eat the dead body, multiply, and immediately start searching for a new host.
Once their source of food is exhausted the nematodes will themselves die, leaving behind no evidence of them ever being there.
Do I need to use nematodes, and if so - when?
Nematodes will only work in areas where pests are already present, they are not effective as a preventative measure.



How do I use nematodes?
1. Water the lawn or soil to ensure it is ready for the nematodes.
2. Fill the Neudorff NemaSprayer or watering can with water and nematode sachet(s). Sachet will not dissolve. Remove after use and dispose of in compost heap or household waste.
3. Apply the nematodes mixture on to the lawn or soil.
4. Keep area moist for the next 3 days (or a week in dry weather).
