Grubs Lurking Below Your Lawn
Now Is the Time to Prevent Grub Damage in Your Central NJ Lawn
If you’re seeing lush green grass right now, don’t get too comfortable — beneath the surface, grub eggs are about to hatch, and they’ll be hungry for your lawn’s roots soon.
Here in Belle Mead, Skillman, Princeton, and all across Central New Jersey, late June through mid-July is prime time to prevent grub damage before it starts.

What Are Grubs and Why Should You Care?
Grubs are the larval stage of beetles like Japanese beetles and June bugs. These tiny white worms live underground and feed on grass roots. A few grubs won’t hurt much, but a large population can quickly weaken and kill your turf.
Once grub populations grow, they cause:
-
Brown, spongy patches in your lawn
-
Grass that easily pulls up like a carpet
-
Attraction of wildlife digging up your yard (skunks, raccoons, birds)

Why Now? Timing Is Everything for Prevention
Adult beetles begin laying eggs in your lawn in mid-to-late July, and within a few weeks, those eggs hatch into hungry grub larvae that start feeding on your grass roots.
That’s why June and early July is the sweet spot for preventive treatment — it gives the product time to settle into the soil before the grubs hatch and start feeding. If you wait until you see brown patches or animals digging, the damage is already done — and fixing that can mean overseeding, and months of recovery.

What Green Valley Is Doing Right Now
We’re currently in Application #3, and that means it’s grub prevention time. Our team is applying a season-long preventive treatment that targets grubs before they hatch and feed. By treating now — in late June through July — we’re building a protective barrier in the soil that stops damage before it starts.
This single application provides effective protection through the grub-feeding window, giving you peace of mind while keeping your lawn strong, green, and grub-free.
