This natural, chemical-free solution targets leatherjacket larvae most effectively in autumn but can be used year-round at double strength. Safe for children, pets, and wildlife, it allows immediate lawn use post-application. The product is perishable with a 2-week fridge shelf life, ensuring peak nematode viability for superior pest control. ## 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. Each 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. ## 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.

It works as we've not had repeated problems with leather jackets. ### ⭐⭐⭐⭐⭐ Easy to use, but it may take a few applications *by on Reviewed in the United Kingdom 18 May 2026* Having a very infested lawn on a new build house I have used this product over the last 2 years and again at the start of this year (2026). You may need to use double doses at the beginning of the year (May) application is by watering can. Can only wait and see in September /October. It's an easy product to use if you follow the instructions carefully. It's safe to use and does harm pets. ## Frequently Bought Together - Nemasys Leatherjacket Killer nematode treatment (200 sqm) - Nematode Applicator Hose End Pouch & Sprayer Makes Applying Nematodes Easy - Nemasys leatherjacket killer (100sqm pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/104729187-nemasys-leatherjacket-killer-nematodes-200-sqm-coverage-pack-of-2](https://www.desertcart.com.ar/products/104729187-nemasys-leatherjacket-killer-nematodes-200-sqm-coverage-pack-of-2) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-08-27*
