The fast and effective way to get rid of chafer grubs and crane fly larvae

Get rid of chafer grubs and leatherjackets from your turf within 10 – 14 days. This safe treatment uses nematodes to biologically control your larvae problems, without harming your turf or other wildlife. Two types of beneficial nematodes feature here: the ones in Nemasys G feed on chafer grubs while the Nemasys J nematodes hunt down leatherjackets (crane fly or daddy long leg larvae). Within 3 days, the larvae will stop feeding, and will die after 10 - 14 days.
