Zoysia Grass Insect Control Guide for Georgia
Insect Control recommendations specifically for zoysia grass lawns in Middle Georgia. Product safety, timing, and what to expect from professional treatment.
Grass-specific care
Why Zoysia Grass Needs Different Insect Control
Zoysia Grass has unique characteristics that affect how lawn insect control should be applied. Zoysia’s dense growth resists weeds naturally, but it builds thatch fast and is vulnerable to large patch disease.
Getting the product, rate, and timing wrong doesn't just waste money — it can damage your lawn. We match every treatment to your specific grass type.

Our approach
Insect Control for Zoysia Grass in Georgia
Grubs and billbugs are the primary insect threats to zoysia in Middle Georgia. Because zoysia recovers slowly from root damage, preventive grub control is more important here than with bermuda. We apply preventive insecticide in late spring and monitor for billbug damage through summer. Catching infestations early prevents lasting bare patches.
Treatment timing
When to Apply Insect Control to Zoysia Grass
Spring
Preventive grub control as soil warms. Scout for billbug activity in established zoysia.
Summer
Monitor for armyworms and sod webworms. Curative treatment if threshold levels appear.
Fall
Check for grub damage in thinning areas. Late-season armyworm generations possible.
Winter
No active treatment. Grubs are below the frost line and zoysia is dormant.

Common questions
Zoysia Grass Insect Control Questions
Why is grub damage worse in zoysia than bermuda?
Bermuda recovers from root damage in 2-3 weeks thanks to its aggressive growth. Zoysia takes 4-8 weeks to fill the same damage, and bare spots stay visible much longer. That’s why preventive grub treatment matters more for zoysia — the recovery cost of waiting until you see damage is much higher.
What are billbugs and how do they affect zoysia?
Billbugs are weevils whose larvae bore into zoysia stems and feed on the crown tissue. Damage looks like scattered thin patches where individual plants die. The grass breaks off easily at the soil line because the stems are hollowed out. Established zoysia lawns are most at risk.
How can I tell the difference between grub damage and disease on zoysia?
Grub damage creates brown patches where the grass pulls up like carpet because the roots are severed. Large patch damage also creates brown patches, but the grass stays rooted and the border has an orange tinge. We diagnose on-site to make sure you’re treating the right problem.
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.
