Thanks for contacting Ask an Expert. Beneficial nematodes are generally available from professional nurseries and garden centers (not big box stores.) Please note that nematodes are very species-specific and must be selected accordingly. Further, as these are live organisms, you will need to follow the application directions carefully. Application methods and Timing are essential factors for success of the treatment.
