You’re faced with a white grub infestation and don’t want to use chemical pesticides? Nematodes are beneficial, microscopic worms that are capable of controlling your infestation. They are mixed in with water to wake them up and then sprayed on the lawn. Once in the soil, they search for a host. The nematodes carry a pathogen that they inject into the host grub, and that pathogen multiplies and kills the grub within a day or two. Then the nematodes lay their eggs on the dead grub. New nematodes go out and search for more, and the cycle continues.
