Nemasys Leatherjacket Killer Nematodes Treats 100sq.m + Nematode Applicator

Always struggled with my lawn in my new build, every year having to overseed a sparse lawn that has more mud than grass. I bought these last year and it’s the first time I have come out of winter with more grass than mud! So I think it’s worked great. I have just purchased another 2 packs to retreat now.

Nematodes we're easy to store and mix when ready to use on my lawn. It would be helpful if the mix was coloured as you can't really tell in the sprayer how much if the concentrate remains in the sprayer. With our water pressure being pretty strong, I was surprise the sprayer didn't have a longer reach from the sprayer output. I got the job done and am looking forward to seeing the results on my lawn.

I have to treat my lawn in spring and autumn for leatherjackets and this product together with the sprayer makes it much easier than filling endless watering cans. The sprayer will be great for lawn feed too. A good product, just dropped one star as I thought the two together were a bit overpriced. Does the job though which is the main thing.

I tried another more expensive applicator specifically for nematodes before this.. this one is far better. This one is made a bit cheaply so parts of the plastic have began to come apart for me after around 20 hours of use. I also find this sprayer useful for applying liquid feeds - they're no so easy to measure the water mix precisely but it works well enough for me.The nematodes do seem to have had an effect. The brown/bare patches in my lawn this year were not down to grubs but just due to the drought and were more minor than previous years thanks to a few applications of nematodes.

The nematodes applicator is not as good as it said, it stuck with all those nematode treat at the bottom no matter you shake/stir it well before you spray, even I have followed the instructions spray longer time than it asked to, still found plenty of treat inside, waste of water/time and money. Finally, we have to order another pack of treat and use watering can to apply those treat with rose head, it’s much more better, we could see all those treat gone.

We were inundated with crane flies over the past couple of years & our grass really suffered. However this year after treatment we have noticed hardly any.

So this arrived today and we stored it in the fridge as instructed and waited for early evening once the sun had gone down and the grass was cut and damp. We then mixed the product with water in the feeder provided and attached to our garden hose. We covered all the lawn and thoroughly went over everything as in the information leaflet, but then when we checked for how much was left in the feeder the level had gone up rather than down. Water had poured into the feeder so we now had more than we started with. It was a waste of time. I kept my son up later to help for nothing, so frustrated. I had read all the reviews about how the rose on the watering can had to be coarse and lots of people saying theirs hadn't worked which is why I chose this feeder that attached directly to the hozelock. No idea why it didn't work because we followed everything to the letter!

Used this treatment on my lawn. Seems to be working for leather jacket grubs. Will see in a few weeks if they are all gone as it takes 2-3 weeks to work.
