What is the primary damage caused by White Grubs?

The primary damage caused by White Grubs is through their feeding on the roots of grass plants. This root consumption leads to wilting and browning of the grass, as the plants can no longer take up sufficient water and nutrients necessary for their health. When the root systems are compromised, the grass becomes less resilient to stressors such as drought or disease, resulting in visible symptoms like discoloration and eventual die-off if the infestation is severe enough.

While other options mention various forms of damage, they do not accurately reflect how White Grubs primarily affect turfgrass health. Chewing leaves pertains more to pest species that feed on the above-ground parts of the plant, which is not typical for White Grubs. Disturbing the soil may occur as a secondary effect but is not the primary damage associated with this pest. Understanding these dynamics is crucial for effective pest management.
