Beneficial nematodes are applied to the growing medium at the first stage in its life cycle. This first stage is also known as the infectious stage. The young nematodes enter into their host via the pest mouth, respiratory openings or the anus. Once inside the host the nematode releases bacteria which then begin to dissolve the host from the inside. The predatory nematodes then feed on the dissolved host. The predatory nematodes will reach adulthood inside of the host and will produce infective stage juveniles. The host larvae dies in a few days after infection. The juveniles will then exit the dead host and seek out a new host. This cycle takes 7-14 days. It is important that the growing medium does not dry out after the application of predatory nematodes. Nematodes move through the growing medium when it is moist, thus a dry growing medium will limit the movement of the nematode and limit its effectiveness. Predatory nematodes will infest a host of pest larvae living in the growing medium pests such as sciarid fly larvae, white grubs, beetle larvae and even fungus gnat larvae.

Application: Soak the sponge for five minutes in a 5 gallon bucket of water (60-70°F). For hydro systems - stir the water well before applying the solution to the reservoir (only use water in the reservoir when applying predatory nematodes). Initiate a watering cycle as soon as possible after applying to the reservoir. For soil - stir contents in the bucket and apply to soil using a watering can. Drench the soil with the nematode mix and keep soil moist for effective control.
