Grub Control, Identification & Treatment
Of the many insects that cause problems for a lawn, grubs are perhaps the biggest threat.
Grubs can wipe out large areas of a lawn and they cause most of their damage before they are even discovered.
Grubs are beetle larvae from a variety of beetles including Japanese Beetles and June bugs that lay their eggs in the soil in July. The larvae hatch in 2-4 weeks and immediately begin feeding on the root system.
Because the damage happens below the surface, it may not be visible on the surface until August or even September.
A full grown grub is approximately 2 inches in length and they start out white in color with brown faces and develop dark tail ends.

GRUB DAMAGE IDENTIFICATION
Grub infestations are highly destructive for a lawn which makes it crucial to recognize the signs of an infestation as early as possible to minimize some of the damage. The turf damage caused by grubs is largely irreversible.
Common grub symptoms include:
- Thinning, wilting, or discoloration (brown or yellow) of the grass, however, these symptoms could also be the result of heat stress, turf disease, or other problems
- Scattered, irregular dead patches
- Spongy feeling turf grass
- Turf easily peels back
- Increased activity of birds, raccoons, moles, and other animals that feed on grubs
Grubs generally hatch in mid July, feeding almost immediately after hatching. Grub damage typically begins to show mid-August and September.
After you have recognized an area that appears to be affected by grubs, next is to identify them.
The easiest way to begin to identify the grubs it to peel back the affected, dying grass area and look for small C-shaped insects under the turf layer.
Grubs can be identified with these distinct markings:
- Body size of 1-2″
- Brownish-red head
- White body which develops a dark tail end (around 3-4 weeks)
Grubs specifically attack the root system of the lawn which does not immediately show signs of damage on the surface.
Once grub damage is visible on the surface, it is generally too late to reverse the damage without removing the affected grass and reseeding the area because the roots have been detached from the grass.
It is possible to prevent or control grubs and minimize the damage once they are discovered with these remedies:
- Treating your lawn early in the season with grub control products such as Merit, Scotts products, or Bayer products
- Treating your lawn with milky spore disease to naturally kill grubs
- Introducing nematodes that feed on grubs
- Hiring professional grub control services
