My lawn is damaged - is it grubs?

White grub damage appears as dead patches (often distressingly large) on lawn areas, and is most severe in the fall and spring. Damaged areas will feel soft and spongy when you walk on them before the grass actually dies. The affected areas lift easily because the roots of the grasses have been eaten by the grubs.

You will often find the C- shaped white grubs under the areas that you lift. Five or more grubs per 0.1 m² (10 cm² ) are enough to seriously damage lawns that are not irrigated. Raccoons, skunks and other small mammals may cause secondary damage on infested lawns by digging up turf searching for a meal of grubs.
