Grubs live in the root systems of plants and cause severe damage over a short period. Unfortunately they are not easy to spot because they live beneath the grass blades, they often destroy large patches of lawn before one notices them. By digging up patches of lawn one will find them.
General browning of grass is one of the signs to look for. Grub feeding destroys the roots of your lawn, leaving the tops to wither and die. Where infestation is severe, even the roots are eaten away.
