4 Destructive NC Lawn Pests and How to Manage Them
Maintaining a healthy lawn in North Carolina can be challenging due to the variety of pests that thrive in the state's diverse climates. Whether you’re dealing with underground pests like grubs or surface feeders like armyworms, knowing how to identify, detect, prevent, and treat these common lawn invaders is essential for a vibrant, green lawn. This blog will outline the four most destructive lawn pests in NC, simple methods to detect them, and effective strategies for managing them.
Identifying Major NC Lawn Pests
North Carolina's varied climate zones—from the coastal plains to the mountain ranges—are home to numerous pests that can damage your lawn. Identifying the major lawn pests in your area is the first step in managing them. Below are four pests that frequently cause problems for North Carolina lawns.
1. Grubs (Japanese Beetle Larvae)
Grubs are the larvae of Japanese beetles and are notorious for their destructive feeding habits. These pests feed on the roots of your grass, often leading to patches of dead, brown grass. Grubs are most commonly found in late summer to early fall when they are actively feeding before they mature into beetles.
- Symptoms: Lawns with grub infestations often feel spongy when you walk on them. Grass in these areas pulls up easily, revealing the larvae beneath. Additionally, you may see increased activity from animals like birds, raccoons, or skunks that are digging for grubs.
2. Surface Feeders (Armyworms, Sod Webworms)
Armyworms and sod webworms are two of the most destructive surface feeders in NC. Armyworms are especially fast-moving and can consume entire sections of your lawn within days. Sod webworms, the larvae of small moths, cause similar damage by feeding on grass blades, leading to brown, dead patches.
- Symptoms: Armyworms leave irregularly shaped patches of chewed grass, while sod webworms typically create round patches of dead grass. Both pests can spread rapidly, especially during hot, dry weather.
3. Chinch Bugs
Chinch bugs are small but damaging pests that thrive in the warm, coastal areas of North Carolina. These insects feed on the sap of grass, causing the grass to turn yellow and eventually die. They tend to cause more significant damage during periods of drought.
- Symptoms: The damage from chinch bugs often appears as irregular patches of yellowing grass. Over time, these patches can spread, causing extensive damage if not controlled early.
4. Mole Crickets
Mole crickets are another common pest in the coastal areas of NC. These burrowing insects cause damage by feeding on grass roots and tunneling through the soil, which weakens the structure of your lawn. Their tunnels can cause the grass to collapse, leaving unsightly brown patches.
- Symptoms: Look for raised tunnels or burrows in the soil, which are often visible when mowing your lawn. Mole crickets may also cause the grass to feel soft or spongy underfoot.
Simple Detection Methods
Detecting pests early is critical to effective lawn management. Here are a few methods you can use to identify pest infestations in your yard.
Signs of Infestation
Look for these common signs to determine if your lawn is infested:
- Discolored patches: Brown or yellow areas of grass, especially those that appear suddenly, are often a sign of pest activity.
- Spongy grass: If the lawn feels spongy or soft underfoot, it could indicate the presence of grubs or mole crickets.
- Animal activity: Increased digging or foraging activity from birds or mammals can be a sign of grubs or other pests in your lawn.
Basic Lawn Pest Tests
Perform a few simple tests to confirm the presence of pests:
- Grubs: To check for grubs, cut a square of turf approximately 12 inches by 12 inches and peel it back. Look for the larvae beneath the grass. If you find more than 10 grubs per square foot, you likely have an infestation.
- Armyworms and Sod Webworms: A soap flush can help bring surface-feeding pests to the surface. Mix 2 tablespoons of liquid dish soap with a gallon of water, pour it over a small section of lawn, and watch for pests like armyworms to emerge.
- Chinch Bugs: If you suspect chinch bugs, place a small, clear container (like a coffee can with both ends removed) over the affected area and fill it with water. After about 10 minutes, chinch bugs will surface, confirming their presence.
Seasonal Monitoring Tips
Lawn pests are most active during certain times of the year, particularly in late summer and early fall when conditions are warmer. Monitor your lawn regularly, especially in the growing season, to catch infestations early. Checking your lawn after rainfall or watering is a good time to spot pests, as they are more likely to surface during wet conditions.
Warning Signs Requiring Immediate Attention
If you notice large patches of dead or dying grass, especially during peak pest seasons (late summer to early fall), don’t wait to take action. Pest infestations like those caused by armyworms, grubs, or mole crickets can spread quickly and cause irreversible damage if not addressed immediately.

Prevention & Treatment
Managing lawn pests effectively begins with prevention. By maintaining a healthy lawn and using targeted treatments, you can keep your lawn pest-free.
Cultural Practices to Reduce Pest Issues
- Maintain a Healthy Lawn: Healthy lawns are better equipped to withstand pest infestations. Regular mowing, proper watering, and fertilization promote strong grass that can resist damage.
- Watering Practices: Avoid over-watering, as this can encourage pests like chinch bugs and armyworms. Instead, water deeply but infrequently to promote strong root growth.
- Aerate Your Lawn: Aerating your lawn can improve drainage and reduce compaction, making it less hospitable to pests like mole crickets.
Targeted Treatments for Common Pests
- Grubs: Apply insecticides or beneficial nematodes in the late spring or early summer, when grubs are in their early larval stage. This will help prevent damage before the grubs mature.
- Armyworms and Sod Webworms: Use insecticides containing pyrethroids, which are effective against surface-feeding pests. Be sure to apply treatments during the evening when these pests are most active.
- Chinch Bugs and Mole Crickets: Apply targeted insecticides during the early spring when these pests begin to become active. Insecticides with carbaryl or bifenthrin are effective against chinch bugs. For mole crickets, consider nematodes or insecticides designed to target their larvae.
When to Call Professionals
If you’re struggling to control a pest infestation on your own or if the damage is widespread, it may be time to call in a lawn care professional. A specialist can accurately identify the pest, recommend the right treatment, and apply it effectively to prevent future infestations.
