Dear Sandy,

So sorry your gardener has let you down in this regard. We don’t work in your area, however, you still have time to control grubs, given the weather this year. It’s not difficult to do this yourself and I wouldn’t wait longer for your gardener. First, have your lawn aerated by a professional service. This will provide a place for any application to get into the roots of your lawn.

Then, if you want to use nematodes as a chemical free, organic choice, your local Home Depot should have a product called “Ladies in Red”.
I found this online:

You could, instead, apply a chemical grub-control pellet. I found one at Home Depot called “Green Light Grub Control with Arena”.
I found this online as well:

I’m not a Home Depot employee or anything, but I know there are loads of stores in many cities. You can also easily find some choices online, but that can be overwhelming. Your local landscape center is a good place to get region-specific information and products as well. Good luck!

“Beneficial nematodes, nature’s way to control Japanese beetle grubs, are microscopic worms that live in the soil. These nematodes actually infest and kill grubs by feeding on and reproducing within the grub’s body. In time, each grub in your lawn becomes a hatchery for 35,000 or more juvenile nematodes, which are ready to search for and destroy more grubs. The more grubs in your lawn, the more the nematode population increases.”
