## Description

Nemasys Leatherjacket Killer nematode treatment (200 sqm)

## Features

- Control leatherjackets naturally by treating with Nemasys Leatherjacket Killer containing millions of natural nematodes.
- It is easy to apply - mix with water and apply the nematodes (Steinernema Feltiae) to the infected lawn with a watering can, 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.
- PACK OF 2. Each pack of Nemasys Leatherjacket Killer treats 100 sqm in the Autumn or 50 sqm when applied at double strength. Full instructions included.
