Understanding Your Enemy: Common Lawn Pests in South Louisiana

Our region’s climate, while perfect for outdoor living, also provides ideal conditions for a range of insect pests that can wreak havoc on your lawn. Knowing what to look for is the first step in defense:

• Chinch Bugs: These tiny insects (about 1/5 inch long) are often reddish-brown with white wings marked with a distinctive black triangle. They are masters of disguise, hiding near the base of grass blades.
  • Damage: Chinch bugs feed by sucking the sap out of grass blades, injecting a toxin that causes the grass to yellow, then turn brown and die. The damage often appears as irregular, spreading patches, commonly mistaken for drought stress. They prefer hot, sunny areas and are particularly problematic in St. Augustine grass, a common choice in our service areas.
  • Detection: Spread the grass in affected areas and look closely at the soil surface or base of the plants. You might see them scurrying about. A simple test involves cutting both ends out of a coffee can and pushing it into the ground; fill it with water, and chinch bugs will often float to the surface.
• Sod Webworms: These are the larvae (caterpillars) of small, white-to-tan moths that flutter erratically just above the grass, especially at dusk. The larvae themselves are grayish-green with dark spots, about ¾ to 1 inch long.
  • Damage: Sod webworms feed on grass blades at night, creating ragged, chewed-up areas. You’ll often see small, irregular brown patches, sometimes with silken tunnels or fecal pellets (small, green balls) near the soil surface. Damage can be severe and rapid.
  • Detection: Look for the moths in the evening. In the daytime, inspect damaged areas closely for the caterpillars or their silken tunnels. You can also mix a few tablespoons of dish soap in a gallon of water and pour it over a small affected area; webworms will often come to the surface.
• Grubs (White Grubs): These are the C-shaped larvae of various beetles (like Japanese beetles, May/June beetles, or masked chafers). They are creamy white with a distinct brown head, ranging from ½ to 1 inch long.
  • Damage: Grubs feed on grass roots, effectively cutting off the plant’s water and nutrient supply. This leads to patches of dead, brown turf that can be easily pulled up like a piece of carpet, as the root system is destroyed. You might notice increased bird activity (as they feed on grubs) or even skunks, raccoons, or armadillos digging in your lawn.
  • Detection: Pull back a section of affected turf. If you see 6-10 or more grubs per square foot, you likely have a significant problem. Damage often appears in late summer through fall.
• Mole Crickets: These unique insects have shovel-like front legs designed for burrowing. They range from ¾ to 1 ½ inches long, light brown, and resemble a combination of a mole and a cricket.
  • Damage: Mole crickets cause two types of damage: Extensive tunneling near the soil surface dislodges roots, causing the grass to dry out and die and feeding on grass roots and shoots.
  • Detection: Look for raised tunnels or disturbed soil. Like sod webworms, they can often be flushed to the surface with a soapy water solution. They are particularly active in sandy soils, which can be found in various pockets throughout our service regions like Burnside and Sorrento.
• Fire Ants: Small, reddish-brown ants known for their painful, stinging bites.
  • Damage: While they don’t directly feed on grass, their large, unsightly mounds can smother turf and are a significant hazard. Their activity can also damage the root systems of nearby plants and compromise irrigation lines.
  • Detection: Distinctive dome-shaped mounds of loose soil, especially in sunny, open areas of your lawn in Baton Rouge or Geismar.

6 Signs You Might Have a Pest Problem (Beyond Just Seeing Them):

1. Irregular, spreading brown or yellow patches: Especially if they don’t respond to regular watering.
2. Thinning grass or bare spots: Areas where the turf seems to be fading away.
3. Wilting grass: Even after adequate watering.
4. Spongy feel underfoot: Indicative of tunneling insects like mole crickets.
5. Increased animal activity: More birds, skunks, raccoons, or armadillos digging in your lawn.
6. Visible insect activity: If you can clearly see large numbers of insects, it’s often too late for minor intervention.
