Our front lawn has been under attack from crows, they have been rooting up

said the previous owners of our property, out in the sticks here in north
Shropshire, had a problem in the 1970's with a Chafer grub infestation

How funny - I found a few leatherjackets grubs last week end whilst
planting trees. Well, not funny really. The birds are your friends
there. However I was told the bestest results are nematodes that you
water in, simply callled Chafer Grub Killers. I've never used it. I
don't have lawn ... Good luck.
