What is a Lawn Grub?

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.

Do You Have Lawn Grubs?

Persistent brown patches in your lawn are one indication that lawn grubs may be present in the soil. As your lawn greens up in spring, keep an eye out for irregularly-shaped dead patches.

If you have not seen many brown patches but your well-watered turf seems spongy, lawn grubs may be present.

Another indication of lawn grubs is when your lawn looks torn apart. 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.

There is a simple test for lawn grubs. Lift up a patch of grass or grab some grass in your hand and pull 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.

How to Control Lawn Grubs
