Nemasys Leatherjacket Killer Nematode Powder 100 sqm Coverage

Really impressed with the Nemasys Biological Leatherjacket Killer! Easy to use and a great natural way to tackle leatherjackets and protect the lawn. Would definitely recommend to anyone struggling with lawn damage and pesky crane flys!

I didn't even know what leatherjackets were until I completely redesigned my garden this year. Turns out my lawn was infested. I had seen over the years patches of lawn that wouldn't grow properly or that just seemed unhealthy. I use pet safe lawn fertiliser around every 6 weeks during growing season but my lawn looked poor. After I found the leatherjacketd I researched how to get rid of them and bought this product. It's easy to use I just dosed into a watering can as advised and treated the whole lawn About 6 weeks later I was weeding and found more leatherjackets. I presumed that this may not have killed all the eggs and so I bought more and reapplied. Now its autumn I cant say if they're all gone, I wonder if my lawn had become so infested its going to take time to resolve. I will buy again in spring amd reapply and see what happens. It is for this reason only I can only give 4 stars. You get a small packet in the box which when opened just looks like a tiny bag of soil. I dont feel its good value for money but time will tell. I can say since application my lawn has never been so green and healthy but I have also been using other new products such as iron sulphate. I had to wait several weeks after applying the nematoades to use any other product as it may harm the nematoades. Do i think its this product or the iron sulphate that has worked? I dont know, maybe its a combination of both. Will I buy again in spring? Yes, but if I see anymore live leatherjackets I wont be buying again. Ive added before during and after images

Saw quite a few leather jackets crawling on my patio in early spring. Applied the nematodes according to the pack instructions and the were gone within a week. I am going to keep applying in early autumn/early spring annually to keep on top of the problem. Quite a few of my neighbours have leather jackets and some of them it has completely destroyed their lawn, literally back to bare dirt. If your neighbours get leather jackets, chances are, you will too. So make sure you are prepared.

My lawn was an absolute state. It was yellow, patchy, and every morning it looked like a flock of crows had held a festival on it – just ripped to shreds. After digging up a patch, I found it was riddled with leatherjackets. I was hesitant to use a biological treatment, as it sounds complicated, but I'm so glad I did. This isn't a "spray and forget" chemical, it's a living product, and you have to follow the instructions to the letter. Here are the vital tips that made it work for me: Timing is EVERYTHING: I applied this in early October. You must apply it when the soil is warm enough (above 10°C) and when the leatherjackets are small and active (usually Aug-Oct). Applying it in spring is less effective as the grubs are too big. It's Alive: As soon as it arrives, get it in the fridge. It has a short shelf life. Do not buy it "for later". Application Day: This is the most important part. The nematodes (which look like a fine, clay-like paste) need water to travel through the soil. You CANNOT apply this to a dry lawn. I waited for a week of miserable, rainy weather, which was perfect. How I Did It: I used a standard watering can with a coarse rose (a fine one will block). I mixed the whole packet into a bucket of water first to create a "stock" solution, stirring it well. Then, I'd add a bit of that stock to my watering can, top it up with more water, stir again, and apply to one section of the lawn. Repeat until the lawn is covered. You must keep stirring to stop the nematodes from settling at the bottom. Aftercare: Keep the lawn damp for at least two weeks after application. My rainy weather solved this for me. The Result: It is NOT an overnight fix. For the first two weeks, nothing changed. Then, gradually, I noticed there were fewer and fewer birds attacking the lawn. Now, fast forward several months, the lawn is recovering beautifully. The patches are filling in and I've had zero new damage.
