Common Lawn Pests in Atlanta and How to Control Them

Maintaining a healthy, vibrant lawn in Atlanta requires more than just proper watering, mowing, and fertilizing. The warm and humid climate of Georgia makes it an ideal breeding ground for a variety of pests that can damage your lawn and garden. Left unchecked, these pests can quickly turn your lush green grass into brown patches and unsightly mounds. Here’s a guide to the most common lawn pests in Atlanta and practical ways to control them.

1. Fall Armyworms

Armyworms can devour your lawn almost overnight. These caterpillars are the larvae of moths and can be recognized by the inverted Y on their heads and the colored stripes running along their bodies. They move in large numbers, feeding on the leaf blades, which leaves brown patches behind.

Preferred grass types: Bermudagrass, tall fescue, ryegrass, and bluegrass.

Active season: Late summer to early fall

Infestation symptoms:

• Rapidly expanding brown patches of grass
• Visible caterpillars on your lawn

Prevention and Control:

• Keep your lawn properly watered, mowed, and aerated to discourage infestations.
• Introduce beneficial insects like ladybugs and lacewings that feed on armyworms.
• Perform a soap flush test by mixing liquid soap with water and pouring it onto a small patch of grass. If armyworms are present, they’ll come to the surface.
• For severe infestations, apply an insecticide like Carbaryl or Chlorantraniliprole or contact a professional pest control service.

2. Mole Crickets

Mole crickets spend most of their lifetime underground, feeding on the roots, stems, and leaves of plants while making tunnels in the process. The tunneling activity disrupts the soil structure, and the lawn can feel spongy when you walk over it.

Preferred grasses: Bermudagrass, St. Augustinegrass and Bahiagrass.

Active season: Early spring through late fall

Infestation symptoms:

• Small, raised tunnels or mounds
• Thinning of grass, which then turns brown

Prevention and Control:

• Especially, dethatch your lawn annually, as the mole crickets are in their element in thatch.
• Confirm the presence of mole crickets with soap flush tests.
• The best time for applying insecticides would be from late June through early July when the nymphs are still small. Professional services could use stronger treatments where necessary.

3. Fire Ants

Fire ants can ruin the beauty of your favorite lawn and can be dangerous since they may sting painfully. These reddish-brown colored ants construct dome-shaped mounds in your lawn and also damage the grass roots while expanding their colonies.

Preferred type of grass: Fire ants may infest any type of grass that is commonly found in the Atlanta lawn.

Active months: Late spring through early fall

• Symptoms of infestation:
• Dome-shaped mounds without a discernible entrance
• Dead grass patches around their colonies

Prevention and Control

• These baits combine insecticide with an attractant to treat your lawn. Fire ants carry the bait into the colony to kill the queen and stop the reproduction cycle.
• For large infestations, the directed two-step method should be used: broadcasting fire ant bait and mound treatments with insecticide.
• Early in the morning when the ants are much closer to the surface, if you want to try a natural method, use boiling water to pour over smaller ant hills.

4. Spittlebugs

Two-lined spittlebugs are small, dark insects with orange stripes. They’re hard to spot since they hide in the grass, but they leave behind telltale signs: a white, frothy substance on grass blades that protects their nymphs. While spittlebugs alone usually do not kill grass, spittlebug feeding weakens an already emerged plant enough that disease and other pests can then cause further dieback.

The preferred grass types are centipedegrass, Bermudagrass, St. Augustine, and zoysiagrass.

Active season: Spring to early fall

Symptoms of infestation:

• Froth White spittle on grass blades
• Discoloring streaks across the grass in brown or yellow

Prevention and Control:

• To keep your lawn healthy, it will need regular watering and mowing.
• Dethatch your lawn and topdress with sand to reduce their habitat.
• Early evening is the best time to apply any pesticide because spittlebugs are most active during this time. In case of a severe attack seek the services of a qualified specialist.

5. Japanese Beetle Grubs

Japanese beetles are serious pests in Atlanta in both the adult beetle and larval, grub stage. Beetle larvae reside in the soil and feed on the roots of the turfgrass, thus eliminating the grass ability to take in water and nutrients. This results in brown patches of dead grass that can be rolled back like a loose carpet.

Preferred grass types: All turfgrass types are susceptible but the grubs also feed on the roots of flowers and other plants.

Active seasons: Summer

Infestation symptoms:

• Brown patches of grass
• Scavenging birds, raccoons, and armadillos digging up the ground.

Prevention and Control:

• Mow your lawn higher; this will enable it to develop its roots stronger than usual.
• Apply a grub-preventive insecticide before the end of July to prevent eggs from hatching.
• Milky spore treatments are also effective in controlling grubs organically.

6. Southern Chinch Bugs

Chinch bugs are minute, dark insects that can be seriously damaging by sucking grass blades and injecting toxins, which prevent the plant from absorbing water. This shows up as patches of dead or discolorated grass that can easily be mistaken for drought stress.

Preferred grass types: St. Augustinegrass is their favorite, but they also attack Bermudagrass and centipedegrass.

Active season: spring through fall

Infestation symptoms:

• Patches of wilting or dead grass; usually spread rapidly
• Chinch bugs can normally be found in the thatch layer of your lawn.

Prevention and Control: Keep the lawn well watered, and dethatch annually where chinch bug inhabits. Perform a floatation test by pushing a pipe into the soil that is filled with water. If these bugs are there, they show up floating to the top. Insecticides are mainly standard for the sole purpose of control of chinch bugs, although there is also a possibility of resistance development and thus the need for professional treatments.

7. White Grubs

White grubs, the larvae of various beetles, are common in Atlanta lawns. They feed on the roots of grass, cutting off the water supply and causing widespread damage. In small numbers, they’re manageable, but larger infestations can kill your entire lawn.

Preferred grass types: All grass types are vulnerable.

Active season: Late summer and early fall

Infestation symptoms:

• Brown patches of grass that can be lifted up
• An increase in birds and small mammals digging in your yard

Prevention and Control:

• Apply a preventive grub treatment in mid-summer to stop eggs from hatching.
• For active grubs, use milky spore or insecticides like trichlorfon.
