Nemasys leatherjacket killer (100sqm pack)

Product Information

Do take note of the leatherjacket lifecycle as they aren’t always active, and nematode predators, for example, are more likely to work during the autumn.

I have a new build property and about two years ago I had beautiful premium quality turf laid it died a little last spring but I managed to revive it with grass seed and watering. While they are a garden pest, crane flies provide a valuable food source to many species including the golden plover.

The microscopic nematodes then seek out the leatherjacket grubs invade them and destroy them from the inside! The nematodes (Steinernema feltiae), seek out the leatherjackets and attack the pest by entering natural body openings.

Also, I have seen the leatherjacket grubs be more active during a milder, wetter winter, so you may find that the damage could be light one year and extensive the next. Should we re-seed immediately or should we now wait until after any crane flies have stopped laying eggs this time around? Leave it at least overnight and then when you lift it in the morning they should all be sitting on the soil surface. To ensure accuracy, we asked Elizabeth Smith to review and fact-check the content before we published it. After losing an entire lawn to Leatherjackets in 2016, I started using the Nematode product twice a year.

Hi Chris, I applied 2 doses of treatment in September /October , mowing often – still, another year, I watch my lawn disappear before my eyes.

Turf growers have no pesticides against them and have no way of preventing them from being in the turf when it’s being cut and then transported to your house.

The only way to control a leatherjacket infection in 2020 is to try to control populations using non-chemical methods.
