slugs in the lawn

lawn is looking very thin with some bare patches - today I discovered lots of tiny white slug-like creatures all over it just under the surface and in what's left of the thatch.  could this be linked to an overzealous application of weed and feed earlier this year? And what can I do about it? will the lawn die? Help please!

    Sounds like the larvae that eat the roots of the grass. Someone will let you know what to do about it. My mind has gone blank.

    Chafer grub is a strong candidate.

    Thank you all of you - it doesn't look like the pics I've seen of chafer grub, but Mike it is wet underneath.  There isn't much thatch as hubby raked it all before and after the feed and weed.  (How long does this take to wear off, BTW?  There are a couple of blackened patches which I think are burn from the stuff...)  Will try to get a picture on tomorrow - I'm new to this!  (And fairly new to gardening. A steep learning curve!)  He did spike it, but didn't use sand, so will try that.

    Could be leatherjackets.  Many people have complained about them this year.

    Here's one of the offenders, and a shot showing the grass looking a bit thin and poorly..

    Thank you so much.  What would you recommend as a "light slug repellent?!  I am reluctant to use too much that is harmful to wildlife - but don't want to see my garden wrecked either.

    the grass will improve when this rain finally stops.

    the hedgehog, frog, black birds, starlings  and thrush,if you are lucky enough to have them,  will eat the slugs, if you don't poison them !

    with so many chemicals being used by gardeners it's no wonder we have so little wildlife                                    

             please think of nature   image

     

     

     

     

  • I think I have the same problem as the original poster. It sounds like the original poster got an answer but I can't seem to find it within the thread image  can anyone tell me if its a grub or slug, and is this what's damaging the lawn and causing the yellow/brown patches and what is the solution?  Apart from these patches my lawn is looking nice and green, it's such a shame that these patches make it quite mottled looking. I know the damage is not from dog pee as he has now been relegated to the gravel area!  I've asked my lawn care company who said water it and see if it recovers if not call them back. An answer would be very much appreciated as I'd like to understand what the issue is before I'm talked into an expensive lawn treatment!
