You can get the better of grubs, though they’re among the most damaging lawn pests in the United States. According to the U.S. Department of Agriculture, Americans spend millions of dollars a year replacing the lawns that grubs destroy. They’re small, white insects with a brown head curled into a “C” shape.
White grubs live a few inches under your lawn and feed on the roots of your grass. Grubs are the larvae-or “juvenile” stage-of various kinds of scarab beetles, including Japanese beetles, chafers, and June and May beetles.
“When grubs are close to the surface, starlings and crows, as well as moles, shrews and skunks, can be seen digging them up because they’re a food source,” says Bayer Advanced; lawn expert Lance Walheim, who wrote the book “Lawn Care for Dummies.”
