Perfect for eco-conscious gardeners seeking effective grub control without chemicals. ## 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 or EasyNem Applicator or Nematode Applicator. Nemasys Leatherjacket Killer is a natural product and is totally safe for children, pets and wildlife and the lawn can be used immediately after application. 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 10c) and are at the most susceptible to the nematodes. You can treat at other times of the year i.e. in the spring and summer, 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. This pack of Nemasys Leatherjacket Killer treats 100 sqm in the Autumn or 50 sqm when applied at double strength. Full instructions included. N.B. It is a perishable product which is sent by 1st class post so please order when you are ready to apply. Review: Effective & easy to apply - This works.

How long does it take?** A: Hi, The nematodes stay alive for up to 6 weeks, so we say to re-apply if needed every 6 weeks. The amount of applications will depend on the size of the infestation, so wait around 4-6 weeks from your last application to check. Kind regards, Lou **Q: How long we can store this at room temperature?** A: Hi, Once you receive them, please keep them in the fridge otherwise they will not survive. **Q: Ordered last Thursday and still waiting for delivery ! Today is Monday, would the nematodes die in transit with the mixed temperatures ?** A: No. Nematodes Direct know their business. You can even store them in the fridge when you get them **Q: If I'm not in to accept delivery straight away will the product perish as it presumably wont arrive refrigerated?** A: The shelf life is on the box I had no problems ## Customer Reviews ### ⭐⭐⭐⭐⭐ Effective & easy to apply *by N***� on 23 June 2026* This works.
