White Grubs in Turf

White grubs are frequent turf pests during late summer and fall. The worms continually damage grass until the onset of very cold or freezing weather. This sends them deep into the soil until their return during warmer late spring and summer temperatures.

  1. Identification

    • White grubs are the larva of May or June beetles. The worms are ½ to 1½ inches long and distinctly C-shaped. The heads and rear are brown and there are three pairs of legs near the head. White grubs belong to the Scarabaeidae family.

    Damage

    • White grubs feed on grass roots causing grass to come up by the roots. Damaged turf rolls up like a rug. Often the root-damaged grass stays green on top. These areas fail to turn green in spring. Examination of soil under the grass is important to establish the grub presence. Infested grass starts to turn yellow, thins and dies. Weakened grass is more prone to drought damage.

    Control

    • Avoid overwatering grass. Introduce parasitic nematodes of Steinernema and Heterorhabditis species as a biological control option. Chemical control options include the use of imidacloprid insecticide. Trichlorfon is a curative treatment that is effective while grubs are already feeding in grass.
