I posted the other day. Now confirmed it was grubs (see 2nd pic). What would be the recommended next steps? More grub killer and wait before seeding again? Or can grub killer and new seed coexist?
Backstory I nuked this lawn last year. Was all weeds. No top soil. Builders just left sod over rocks and clay. All water would just run off. Eventually sod died and weeds took over. I put down 3 inches of top soil. Seeded. And watered meticulously last fall. Lawn looked great all through fall, spring, and most of summer. Then died very suddenly. I had put down preventative amount of Scott’s Grub-ex in early spring. Pretty sure the HOA landscaping crew had propagated them throughout the neighborhood as others are dealing with the same. By the time I noticed it was too late (we were away on vacation).
Any tips are appreciated. Thanks all.

Bastardos!
What method did you use to put down 3 inches of topsoil?
I’m currently dealing with the same problem. Following for advice
Last fall I was hit with grubs right when the new grass started growing. This was early October. I put down some Grubex then overseeded again right afterwards. Grubex isn’t a herbicide. This was mid October and my lawn really bounced back. Helped that we had a pretty warm October.
Best treatment I use for grubs already present: Arena. It’s expensive, but it works, and fast.

I had this problem terribly and have limited chemical options here in Canada. I got beneficial nematodes, ordered from Costco online. Attached right to the garden hose and blast those fuckers. You can only apply them at certain times- I believe spring. Has to be when the grubs are larvae stage- the nematodes eat them. Anyways, this cost me about $50 one time, and I have not had a problem since. And good for the environment!
