When is a common preventive grub control timing for warm-season turf?

• A. Early Winter, before grub activity begins
• B. Fall, during dormant turf
• C. Late Spring to Early Summer, aligned with grub activity
• D. Late Summer, after grub activity peaks

Answer: (C)

Preventive grub control works best when you target grubs during their early, vulnerable feeding stage right after eggs hatch. For warm-season turf, that happens in late spring to early summer as soil warms and adult beetles lay eggs that hatch into small grubs. Applying then ensures the insecticide is in place in the root zone as young grubs begin feeding, giving effective protection to the turf roots and taking advantage of the insecticide while the grubs are most susceptible. Waiting until late summer means the grubs are larger and tougher to kill, and damage may already be done, while applying in winter or during dormancy isn’t effective because grubs aren’t actively feeding and turf uptake is limited.
