Biological Control of Leatherjacket - 2 pack sizes

Damaging leatherjacket larvae are laid as eggs in lawns during August by the Crane Fly. Nemasys J is an excellent method to naturally control leatherjackets by using the beneficial parasitic nematodes in Nemaysy J.

The Nemasys J nematodes enter the larvae and stops them feeding within three days of infection. The larvae then die within 10-14 days. 

The nematodes complete their life-cycle within the larvae, then enter the soil seeking more hosts, and so the pest control continues naturally.
