Your Guide to Grub Control for North Carolina Lawns

Learn about grub control for North Carolina lawns.If you’ve noticed any dry, brown patches on your lawn, it’s easy to assume that it’s due to the summer heat or dryness, and that you just need to water your grass more. While this may be the case, it could also be due to a more serious problem—grubs.

What are Grubs?

White grubs, also known simply as grubs, are the larvae of various scarab beetles. They are white or cream c-shaped insects that have soft bodies and six small legs.


Common types of grubs include Japanese Beetles, Green June Beetles, Northern Masked Chafer Beetles and European Chafers. In North Carolina, Japanese Beetle grubs cause the most damage to lawns.

Why are Grubs a Challenge for North Carolina Lawns?

Grubs live below the surface of the soil and feed on grass roots. Heavy infestations will cause areas of your turf to die. This damage looks similar to dry stress, and many North Carolina homeowners mistakenly assume the lawn only needs water to restore its appearance. Persistent grub feeding will cause permanent damage to your lawn, killing the turf, requiring you to renovate these areas.


Other signs of grub feeding include:

  • Brown patches that don't turn green with watering

  • Irregularly shaped dead patches that appear in your well-irrigated lawn

  • Birds, skunks and raccoons feed on grubs, leaving holes in your lawn

  • Your lawn feels spongy. This can happen before any brown patches appear, and it’s often the first sign that grubs are present and your lawn’s root system has been eaten by grubs

  • Severely damaged turf will roll back like a carpet because its root system is destroyed

When are Grubs a Problem for North Carolina Lawns?

Learn about grub control for North Carolina lawns.People are most aware of these lawn pests in their adult form, the flying beetles often seen feeding on landscape plants. After approximately 4-5 weeks of feeding, mating, and laying eggs in lawn areas, the adult beetles die. A few weeks later, their eggs hatch into the notorious grub larvae underneath the surface.


As grubs feed through the latter part of summer and early fall, serious damage occurs to lawns. As the weather cools in fall and winter arrives, grubs burrow deeper into the soil to overwinter. In spring, they begin feeding for a very short time, and then pupate to turn into the flying adults which emerge in early summer.


Your only hope to protect your lawn from grubs is to apply a grub control treatment.

How to Treat and Control Grubs

There are two approaches to grub control for North Carolina lawns: curative and preventative. If your lawn has already experienced damage due to grubs in the fall, your only option is to apply a curative treatment to eliminate the existing grub population. If this is the situation you’re in, after applying a curative grub control treatment, you should consider adding a preventative grub control treatment in the future.


Preventative grub control for lawns reduces grubs by applying a product to the lawn prior to the grubs rising to the root zone in the late summer. This product will remain active for several months, controlling grubs as they begin to feed. It’s not only a more cost-effective way to control grubs in your lawn, but it will ensure that damage doesn’t happen.
