Nemasys Leatherjacket Nematodes

from £20.70

Eliminate leatherjackets naturally with Nemasys nematodes, a safe and effective treatment for lawns and flower beds.  

Grand total

These tiny nematodes will clear your lawn and flower beds of leatherjackets – without harming anything else. So easily, so naturally.

You’ll need a watering can, a stirrer and a packet of Nemasys’s nematodes. Then, a couple of weeks after you see the crane fly, drench the ground with the mixture.

No need to worry about kids, pets, Honey Bees or song birds – it’s totally harmless pest control. Except to leatherjackets of course.

Please remember a couple of things though.

Always refrigerate the pack when you receive it, keep the treated ground well watered and apply when the temperature is above 12 degrees Centigrade – although perhaps best not to apply it on too hot a day as it may dry out too quickly.

Also, these nematodes can only really be effectively applied between late summer and earlyish Autumn, up to say mid-October.

Full instructions are included with the pack.

Available in packs of 100 sq yard or 550 sq yard coverage.
