About This Service

Grubs are the larval stage of any of several beetles that can do damage to turf grass. Japanese Beetles, Masked Chafers, European Chafers, Green June Beetles and May/June Beetles are the most common pests present.

The larvae live in the soil out of sight and sometimes out of mind. They do their damage by feeding on the roots of grass plants usually in mid to late summer.

The damage shows up when enough feeding has been done to reduce the effective uptake of water to the plant so the plant wilts and dies. Preventative treatments can be done early in the summer or spot treatments can be done when grub damage begins to develop.
