Nemasys Leatherjacket Killer nematode treatment (100 sqm)

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.

Easy to use for large areas. No instructions on how to divide if using on smaller sections

Since purchasing my first treatment, I have bought, as Nemsey suggested, a second treatment. I must say, my lawn has never looked better, no unsightly yellow spots, and it is an indicator of Leatherjacket activity

We had infestation of leather jackets destroyed the whole lawn to just dirt . Once identified we ordered the above and carefully followed instructions as the solution worked thousands appeared soon eaten by birds. Absolutely wonderful

I've used this for first time as parents swear by it. The leather jackets have left my lower lawn just a mud patch, destroyed the complete lawn. Last night was bad rain, let the dog out and the patio was covered in leather jackets😥 I used this in January where it's under 10oC and extremely wet so not sure if this has effected it working. Will defantly try it again

Arrived promptly and in good condition. First time I have used this product but noted it's sell by date was nearly up ( use by November ) So hope once it's applied it is still going to do the job, Only time will tell. The only reason I have given it 4 stars as noted the sell by date!

Simple and effective way to save your lawn from disaster after a summer with a very high volume of crane fly larvae munching at the roots

Put this down a week ago and already there are signs that the leatherjackets are being killed off. Good stuff.
