How to get rid of grubs?

Grubs—Japanese beetle larvae and similar species—feed on grass roots, creating brown patches and weakening turf. Effective grub control requires understanding the pest lifecycle and applying appropriate treatments at optimal times. In Charlotte's climate, white grubs are active from late summer into fall.

Identifying Grub Damage

Brown patches appearing in late July through October often indicate grub damage. Grass pulls easily from soil as roots are severed. Birds, moles, and raccoons may damage turf while foraging for grubs, creating additional evidence of infestation. To confirm, cut and lift grass sections; visible white C-shaped larvae confirm grubs (typically 8-12 present per square foot indicate treatment need).

Grub Treatment Options

• Preventive Treatments: Apply in June-July before eggs hatch. Imidacloprid and other neonicotinoids prevent larval feeding. Apply to dry grass and water in
• Curative Treatments: Apply once grubs appear (July-October). Japanese beetle grub control products are most effective on younger larvae (July-August)
• Biological Control: Beneficial nematodes prey on grubs. Apply in August-September when soil is warm and moist
• Cultural Control: Healthy turf tolerates moderate grub populations without damage. Strong fertilization and watering support recovery

Application and Timing

1. Monitor lawn in early August for grub damage signs
2. Apply preventive in June if history of problems exists
3. Water treatments into soil thoroughly after application
4. Avoid excessive moisture for 24 hours after application to allow product to work
5. Maintain turf health to support recovery from any damage
