Safe for children, pets, and wildlife, it offers an eco-conscious solution that can be applied easily with common garden tools and keeps fresh refrigerated for up to two weeks. ## Description Control leatherjackets naturally by treating with Nemasys Leatherjacket Killer containing millions of natural nematodes – mix with water and apply the nematodes (Steinernema Feltiae) to the infected lawn with a watering can, EasyNem Applicator or Nematode Applicator. It is best to treat in the Autumn i.e. Sept/Oct/Nov as this is when the leatherjackets are newly hatched, the soil is warm (needs a daytime soil temp of 12c) and are at the most susceptible to the nematodes. You can treat at other times of the year i.e. NOW, but you must treat at DOUBLE STRENGTH as the mature leatherjackets are much harder to kill. Nemasys Leatherjacket Killer is a perishable product, which will keep for up to 2 weeks in the fridge, so please order when you are ready to apply. Nemasys Leatherjacket Killer is effective at killing leatherjackets, but is harmless to children, wildlife and pets and the lawn may be used immediately after application. 5 x Nemasys Leatherjacket Killer 100 sqm packs treats up to 500 sqm in the Autumn or 250 sqm when applied at double strength. ## Features - 5 x 100 sqm packs treats up to 500 sqm in the Autumn or 250 sqm when applied at double strength i.e. in the spring and summer. - Control leatherjackets naturally by treating with Nemasys Leatherjacket Killer containing millions of natural nematodes – mix with water and apply the nematodes (Steinernema Feltiae) to the infected lawn with a watering can, EasyNem Applicator or Nematode Applicator. - It is best to treat in the Autumn i.e. Sept/Oct/Nov as this is when the leatherjackets are newly hatched, the soil is warm (needs a daytime soil temp of 12c) and are at the most susceptible to the nematodes.
