Crane Flies in your lawn? Nemasys Leatherjacket Killer (100 Sqm) - £16.99 delivered at Gardening Naturally (+ potential 4.25% TCB)
Posted 14th Sep
It seems to be the time of year for Crane Flies/Daddy Long Legs and if you have a lot in/around your lawn there's a good chance you could have their larvae (Leatherjackets) in your lawn doing some damage. I was looking for something to rid my lawn of them and came across Nemasys Leatherjacket Killer. Over 4k items of this application sold on ebay for £19.99 (item link) but if you buy directly from them it's £16.99 delivered. Better still, go via TCB for a potential 4.25% cashback. Delivery can be set from this Thursday.

UPDATE - Just to confirm these are nematodes (microscopic creatures), NOT poison (as has been mentioned a few times in the comments).

What are Leatherjackets: Leatherjackets are the larval stage of the crane fly or daddy-long-legs. When you start to see the adult daddy-long-legs in your garden (normally towards the end of August) you will know that in a few days they will be laying eggs. These will hatch quickly, within two weeks and start causing damage to your lawn.

What are Leatherjacket Nematodes: Leatherjacket nematodes are used to stop the larvae of the crane fly or daddy-long-legs. The larvae are about 2.5cm (1" long), greyish black in colour, legless and with no distinct head.

Damage From Larvae: The young crane fly larvae start to feed on the roots of grass, continuing throughout Winter and into Spring.

I await the terrible fashion related leather jacket jokes, but also interested in if this is of use to anyone else or if you think this can be found cheaper elsewhere. Hope it's of use to someone.

If you've wondering why your newly laid grass lawn gets overtaken by weeds after a few years even if you keep it watered... Leather jackets are normally the cause, eating the lovely juicy roots. This stuff seems to do the job but follow the instructions to the letter and once you get your delivery use it as soon as possible, I was just thinking about ordering this as I noticed the craneflies about last night. Looks like a good price, thanks OP!

Thanks, good advice. Glad the deal is of use

Also worth double dosing and doing again in March-April, note lawn temps should be above 10 degrees so need to get these down by end of Sept ideally.

Anyone living on relatively newbuild developments etc. are likely to experience these nightmares (even if you dont know why your grass looks terrible) and our lawn this spring looked something like these pictures - used to be able to use a chemical treatment to kill them but was banned a few years ago and even the nemetodes only work 50% of the time sadly

I’d never heard of leatherjackets until a few years ago. Moved into a new build and they devastated the lawn. I retrospectively treated it with this stuff and it did grow back but at the time it was a right mess

Just treated my lawn again these are a right pain to get rid of.

New build treated in spring and again in September

Another way is by covering sections of your lawn up for 24 hrs as they come to the surface if you cut out the light then just pick them up good fishing bait.

This is for smaller lawns 50 Square meters £12.99

I didn't know this was even a thing, so thank you OP! I don't need it at the moment but will keep it in mind in case I see my lawn going dodgy.
My dog used to be able to sniff these nasty things out and would dig up the lawn to get them.....making a bad situation even worse!!

Well, I said in the OP I was waiting the fashion and leather jacket related 'jokes'.....can't grumble too much at that one!
Great advice about something I knew nothing about. I love HotUKDeals for this exact reason. Heat from me!

Now if only it could tell me how to find a girlfriend?
Do they look like small slugs? Ive had them appearing at my doorstep the last few days!
Heat, if nothing else, for learning leatherjackets were crane fly larvae.

Just like QI here.

Ant powder kills leather jackets too. Hope this helps.
I bought some stuff that controls leather jackets but it's supposed to be for agricultural / professional use.

Took me a while to find someone that still sold it!!

Extremely unlikely. You normally coma across them when you're digging in the lawn. They're like large maggots (bit darker).
Really can't see the point of this. What else is killed by this poison? Blackbirds etc dig these up & eat them.
In my experience, nature finds its own balance & there is no need to kill them.
Vine weevils are another matter!

I understand your view point, but I think some of the photos above suggest otherwise (with regards to the balance).

EDIT - Also just to confirm these are nematodes (microscopic creatures).

I take your point - and you may be right. But the problems could have had another source. But we'll never know.
I must say that I come across them all the time when I'm going various things with the grassy parts of my garden (6 acres!) but they are normally in areas where the grass is perfectly healthy.

Sounds like they have more room to spread out I guess most of the time things do remain in balance, but when they don't and you need to re-address it this product might be one way to go about it.
I attract plenty of birds to my garden and never had leather jacket issues. Birds love eating leatherjackets plus plenty of other pests in the garden.
You should see a flock of starling in action. They soon eat a lot of the little blighters.
Embrace nature and it will repay you ten fold.
Yes, because we all need more poison in our environment and less insects... Get rid of lawn, cut a tree and build a parking lot. Then drive miles to a museum, pay a pound to see it.
These nematodes are not a poisonous chemical though. Its an organic gardening solution that uses other organisms to combat the pests naturally.

Having said that lawns are pretty poor for wildlife anyway, but a million times better than paving over your garden or decking or whatever the latest fad is.

Vine weevils are the work it the devil! Little fookers

If you think these are bad, chafer grubs are even worse! No simply way to control, either!

I do feed and have birds in my garden but still suffer. As mentioned above these are nematodes rather than any chemical etc (they are all banned for the treatment of Leatherjackets).

No worries. I'm not knocking the deal as it is non-chemical. But just a suggestion for 'extra' help to fight the L. Jackets
Mind you I've had a mole so my poor old lawn suffered in other ways. :-) Luckily the little fellow has gone somewhere else.
