Organic Parasitic Nematodes, Heterohabditis bacteriophora

Heterorhabditis bacteriophora are live beneficial nematodes selected for susceptible insect stages below the soil surface. Their listed targets include ants, Colorado potato beetles, cucumber beetles, flea beetles, fleas, grubs, Japanese beetles, leafminers, termites, and ticks. Correct identification matters because different beneficial-nematode species seek different hosts and occupy different parts of the soil profile.

• Coverage options: Choose the 10-million garden size or 50-million farm size shown in the variant selector.
• Temperature range: Use when soil is 42–90°F and nighttime air temperatures remain at or above 42°F.
• Preparation: Premoisten the application area, mix the living organisms according to the supplied directions, and avoid equipment or filters that conflict with those instructions.
• After application: Irrigate lightly to move nematodes into the target zone and maintain suitable moisture. A second treatment 7–10 days later is recommended.

Apply promptly after delivery and follow the package requirements for storage, water temperature, application timing, and equipment. Evening or other low-light application helps limit drying while nematodes enter the soil. The current product record identifies this input as certified for organic production.
