When we came back from Spain, our lawn was in a terrible state and looked like something had been digging underneath it. It was all bumpy and it was threadbare in places. The lawn keeper truly believed that someone had been in and sabotaged it, as it looked so bad! This picture was taken today so you can see what a state it’s in!
Eventually after much research on the inter web, we discovered that it must be leather jacket grubs which are the caterpillars from crane flies.
I always assumed they were harmless creatures, which I think they are, but their offspring can decimate a lawn in a couple of months.
Apparently the eggs are laid in the lawn in the Autumn and then hatch out early spring. That’s when they chew up the lawn and eat the roots. This is then followed by the birds and squirrels pecking at the lawn to eat the grubs which makes it even worse.
We have seen the grubs on the patio but didn’t know what they were. They look revolting as you can see.
It seems that there are no pesticides that you can use to get rid of them. You have to resort to wetting the lawn, covering it in black plastic, wait for them to rise to the top and them pick them up!! Well, him indoors has said he won’t be doing that. I feel really bad for him as he takes great pride in the lawn and has spent many hours scarifying, aerating, over seeding, watering, mowing and weed killing the blessed stuff and to have a load of ugly grubs undo all your work is soul destroying.
We’ve now discovered that you can buy a biological control to help get rid of them. It’s a nematode which you water into the lawn. It’s safe and environmentally friendly. So we’ve ordered some and are going to give it a go.
