Hello, I'm having a hard time growing grass in areas of lawn. The lawn is non-irrigated. So are many of my neighbors. We live in a townhome community Hyland Townhomes in Bloomington, MN. I was digging in the dirt yesterday and these grubs (see pictures) were everywhere buried in the soil. The pictures were taken about 2-3 hours after digging and exposing the grubs. What are they? Are they a serious threat? What's the best way to get rid of them?

Please check out the references for advice on if control is necessary and when it is most effective. Fall is rarely the time to treat because the larvae are too big.
