Weed Man Lawn Care: Diagnosing White Grub Damage

If your lawn appears yellow or brown, you might think it simply needs more water, but the problem could be caused by white grubs. White grubs are the larvae of insects such as Japanese beetles, May or June beetles, or the European chafer. While the beetles themselves present no danger to your lawn, large congregations of their larvae can cause extensive damage to your grass.

White Grub Damage

White grub damage

Small, fat, C-shaped, brown-headed white larvae devour the root systems of grass underneath the soil’s surface layer. This limits your lawn’s ability to absorb moisture and maintain long-term health – not good! You may not notice a problem until toward the end of summer or even fall, when the white grub population has become dense enough to cause significant damage.


One sign of white grub damage is the presence of urban wildlife, such as raccoons and skunks, digging up your yard to feed on the larvae. Additionally, birds may peck pencil-shaped holes into the ground, causing the surface of your grass to loosen from the roots to such an extent that it can be rolled up like a length of carpet.

An untreated white grub problem can devastate your lawn. At the first sign of trouble, contact an experienced lawn care professional who can diagnose the situation and prescribe the best course of treatment. Weed Man Lawn Care not only provides comprehensive lawn care and outdoor pest control treatment, it also partners with its customers to offer education on the best practices necessary to maintain a lush and healthy yard.
