Do You Have Lawn Grubs?

Lawn grubs, also called white grubs, are white, C-shaped creatures that are about a half-inch to two inches in length and have soft bodies with legs near their heads. These worm-like creatures are the larvae of different types of scarab beetles, such as Japanese Beetles, June Beetles (June “Bugs”), and Masked Schafer Beetles.

Lawn grubs feed on grass roots and cause sections of your lawn to die. When they have finished root-munching for the season, they will turn into pupae and then into adult beetles. The adults will emerge from the soil, mate, and lay eggs that will hatch into more grubs about two weeks after being laid, in mid-to-late summer.

Persistent brown patches in your lawn are one symptom of lawn grubs. Well-watered turf that seems spongy is another. If your lawn looks torn apart, it could also be an indication of grubs. Grubs are a tasty treat for birds, skunks, raccoons, possums, and moles, and they will dig for them in your lawn. These animals also like earthworms, however, so Inspect your lawn to confirm that grubs are present before beginning treatment.

A simple test for lawn grubs involves lifting up a patch of grass or grabbing some grass in your hand and pulling it up. If the grass is infested with grubs, the grass and its sod will pull easily out of the ground (because there are no roots). If you turn the sod upside down, you will see the grubs curled into C shapes underneath. Get rid of any grubs you find by dropping them into a bucket of warm, soapy water.
