[Arid_gardener] bob sod insect question

[jwalters38 at cox.net]

Hi
I read a post of yours on a turf forum and thought you might be able to help.  I've just come back from a 2 week trip to find my Bob sod dying out in an approximately 10x12' section.  After mowing today, I was able to pull up chunks of turf/dirt that had white round wormlike insects in it.  Actually, rather infested.  They don't look like any worms I've ever seen and I'm suspected grubs.  Do grubs attack grass?  There is a mesquite nearby but?  What treatment options would you suggest?  Can I save the grass?  I've had the sod for four years and it's been fantastic.  I'd appreciate any help you can provide.
Thanks.
