What is the primary damage caused by White Grubs?

The primary damage caused by White Grubs is related to their feeding habits on grass roots. As larvae of beetles, White Grubs burrow into the soil and consume the roots of grass plants. This root damage disrupts the plant’s ability to absorb water and nutrients, which can lead to wilting and browning of the grass.

When the roots are compromised, grass becomes stressed and begins to lose its vigor, resulting in patches of brown or dying turf. This visible decline in turf health is a direct consequence of root damage rather than any direct feeding on the leaves or disturbance of the soil itself. Thus, the symptom of wilting and browning of grass accurately reflects the impact of White Grubs on the turfgrass ecosystem.
