I’m assuming this is bugs? I’ll pick up some spray today. Is it best to treat the entire yard or only the spots affected?

My lawn was great then started seeing exactly what your pics show. Put down Talstar and have gotten several rains and have been watering and it’s recovering. Started seeing the moths so I assumed sod web worms.

You’ve got something eating the blades and if it’s army worms they have not been there that long. You said it’s been a couple weeks and army worms would have erased your lawn by now.
You do have grey leaf spot and that is causing a lot of discoloration and lack of grown.
Head over to site one and get a bottle of Talstar or Wisdom and a bottle of propiconizole. You can mix them in the same backpack.

Good video on the monster worms... Link to his website in the description. He recommends Anderson’s Duocide, which is what I use. Contains bifen in it as well, which is essentially Talstar.

I recently (early July) had what looks like the same issue in my newly planted St Aug. I reached out to the LSU Ag Center and was told it was tropical sod web worms--they did a number on my lawn (actually quite a bit worse than yours). Based on your pics, I believe you have the same problem. I noticed in one of your pics (the one with your thumb) that there is a white residue on your thumb and on the grass--I was told this frass (excrements from the larvae).
I did two applications of granular bifenthrin and have not seen any new damage. Hoping I caught it early enough for my lawn to recover.
