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.
