Our approach
Insect Control for St. Augustine Grass in Georgia
Chinch bugs are the number one insect threat to St. Augustine grass. They feed on grass blades near the soil surface, injecting toxins that kill the tissue. Damage starts in sunny, stressed areas and expands rapidly. We apply preventive treatment in early summer before populations explode and monitor through fall for secondary generations.
Treatment timing

Summer

Common questions
St. Augustine Grass Insect Control Questions
How do I know if chinch bugs are killing my St. Augustine?
Chinch bug damage starts as irregular yellow patches that quickly turn brown, usually in the sunniest, hottest parts of the lawn. The damage looks like drought stress but doesn’t respond to watering. To confirm, push aside the grass at the edge of a damaged area — you’ll see small black-and-white bugs moving at the soil surface.
Why do chinch bugs target St. Augustine more than other grasses?
Chinch bugs are strongly attracted to St. Augustine’s thick thatch layer and broad blade structure. They feed by piercing blades and injecting a toxin that blocks water movement in the plant. While they’ll feed on other grasses, St. Augustine suffers the most damage because it’s their preferred host.
Can chinch bug damage be repaired?
If the root system is still alive, St. Augustine will regrow into damaged areas over 3-5 weeks with proper watering and care. Severe infestations that kill roots may require sodding or plugging the damaged sections. Early treatment prevents damage from reaching the point of no return.
How do I know if my lawn has insects?
Brown patches that get worse despite watering, grass that pulls up easily (grubs), and birds pecking aggressively at your lawn are common signs. The soapy water test can flush armyworms to the surface.
When is insect treatment most important?
Late spring through early fall is peak insect season in Georgia. Preventive applications in early summer stop grubs before damage shows.
