I've been really busy and out of town the last month or so and basically missed all the signs that my yard is suffering from a massive grub infestation.
This was my yard on July 31st:

It used to be very thick.
Much of it in huge patches turned yellow and died off in about a week's time.
After heavy dethatching to remove the dead grass, aeration, a low mow and 3 days of heavy rain, it looks like this:

The turf pulls up in big sections like carpet, and I am finding around 10 full-size white grubs per sq ft.

Im worried the grubs will feast on any seedlings that pop-up from my overseed.
Clearly, its too late for a preventative measure, like Imidacloprid.
What on earth can I spray at this point to try to knock their numbers down a bit?
It looks like carbaryl and trichlorfon are the only 2 items for curative remedies.
The old formulation of "Sevin" Bug Killer used to have carbaryl but now its been replaced with Sevin Insect Killer with Zeta-Cypermethrin.
Is it too late at this point?
Do I have to bite the bullet and pony up $160 for some Bayer Carbaryl 4L Sevin?

Its my understanding that I'll need several applications, since the grubs are fully mature at this point.
