Spada you prompted me to quiz you on spraying lawn for grubs
Have you got a grub killing the grass?
I’m thinking I may have something killing the grass and suspect maybe a grub but they are not obvious.
What did you spray with?
You can get Lawn grub and Black beetle killer from a hardware or nursery. Telltale signs are patcy, brown grass areas, small, white moths and 'Ponytail' wasps. They're wasps with a long, black, thin tail.
Don't use anything if you have flowers with bees foraging during the day. Do it at night, careful to avoid flower contact with the spray.
Another way to tell is to lay a wet hessian bag on your grass overnight and have a bo peep under it in the morning.
I have used and found the 'Eco Friendly' stuff available to be just that. It wouldn't kill an ant. As a matter of fact any 'Eco Friendly' stuff I've used for different applications i.e weeds etc have not worked too well.
