I’m not sure if our curl grub infestation in the lawn is bad enough to warrant treatment.
Our raised garden beds had a lot of them that I picked out and disposed of whilst preparing for our summer crop. I’m sure for every one I found, there were several I didn’t however.
The nearby lawn always struggles in places, but we do have other issues such as shade and children playing sports on it. No obvious brown patches however and not “spongy”. I’ve tried the methods to find curl grubs that I’ve seen online (wet towel, soapy water etc) and they’ve never surfaced, however today when I was weeding (A LOT of weeding!) I found 2 grubs under the soil.
Do I just treat it just incase? Is there the potential to harm the grass with the treatment? Ie. what have I got to lose?
Thank you
EDITED to include photos as requested. The brown patches are all either where I’ve recently sprayed clover and it’s died (the was a lot of clover) or bare patches from the kids playing soccer. Today I aerated and put top dressing on the worst parts in the hope the lawn will spread and fill in the bare patches. There are no patches I can’t attribute to dead weeds or trauma. It was fertilised about 3 weeks ago

Hi @liz11
If you've had grub infestation before, I suggest following @Adam_W's recommendation and using Scotts Lawn Builder 4kg Grub + Insect Slow Release Lawn Fertiliser. It's never too early to do some preventive maintenance especially when it comes to curl grubs. Just remember to use the product as directed. As for the bare patches in your turf, I suggest using Lawn Seed to repair them.
If you need further assistance, please let us know.
