My 2.5 year old lawn has been demolished by leather jackets, around 50% of it has been ruined now.

Most of the methods Ive researched all seem to be suitable for small gardens, but my lawn is over an acre in size.

What would be the best method of ridding myself of these pests?

IM sure golf courses and farmers have the same problem you could check out NAD or Turfcare. Have a look at these links.

There are natural products on the market to kill the leatherjackets that would work for larger areas. They contain a parasitic nematode called steinernema feltiae, which kills leatherjackets but is harmless to children, wildlife and pets. They are effective when the soil is above 10°c / 50°f

An acre a little too big to dig and the birds can look after themselves???

Thanks for the replys lads.

There's a few problems with your suggestions.

The nematode solution requires the lawn to be constantly watered for a fortnight, which would require a hell of a lot of sprinklers.

The digging up solution would require an acres worth of reseeding, again a huge expense.

I don't really have the means to be re-doing the whole lawn again at this moment in time.

Hi Danyosan

This came up at the top of google when I typed in leatherjackets organic get rid of etc... http://www.greenguard.nl/en/emelten

How about turning it into a flower meadow? it'd only need cutting once or twice a year

Back to this again.

I left the lawn, as after researching I found that the best time to attack them would be Aug/Sep time. In the meantime the lawn had grown back fully.

I thought maybe the birds had eaten up all the grubs, but a whole load of crane fly have appeared in the past few days.

My question is, am I definitely going to have to treat this problem as it will keep getting worse, or is the fact that the lawn repaired itself mean I could leave it be as the lawn is another year older?

Laughing

I'd have taken the blame if I had actually gone through with it!
