I believe I have a grub problem in a small proton of my yard. I have attached photos. I would appreciate a treatment plan recommendation with attention to timing, pesticide active ingredient, pre cautions with seeding, etc. Thank you.

Grubs are not unusual in lawns, but grub damage is actually pretty rare in lawns. Many other things can cause dieback in lawns.

It's normal to find a few grubs when turning over soil. (In fact, it's good to have a few--because it keeps grub predators and diseases around.) Read about the threshold at which grubs can be a problem: This page also includes a link to controls if that is necessary.

Unless you have a true grub problem, don't apply grub control. It will be a waste of money. More importantly, it does not only affect grubs. It is toxic to many organisms in your soil's ecosystem which you do not want to unbalance.
Fall is the best time to overseed and fertilize. Mid-October is the recommended cut-off for overseeding.
