Turf Insect Control: Grubs

Grubs are a common problem for many home owners. Because they dwell under the surface of your turf, it is not always easy to spot a problem until it's too late. These pests feed on the root of grass and can cause mass devastation; stressing the turf, or worse, killing portions of the lawn.

Grubs are the larvae stage of Beetles. In summer, the beetles feed on foliage, mate, and lay eggs. The eggs hatch in late summer through fall. The result; a hungry grub which needs to consume enough carbohydrates to over winter. Around June the following year the grub enters their adult stage (beetle) and so the cycle continues.

Most of the damage occurs in fall, though grubs will also feed briefly in spring prior to entering their adult stage. Grub control is applied in summer as a preventative - not a curative. It is designed to target the late summer/fall hatchlings which is the same generation that comes up the following spring.

As grubs eat at the root of the lawn, they disrupt the turfs anchor, allowing for pull-back (like a loose carpet). Once the root zone has been depleted, the turf will experience die back. Damage can be noted in fall.

The best approach to grub control is preventing them in the first place. During the summer months, Grounds Services can apply merit to help protect your lawn from these pest.

Frequently asked question: Does Grub Control prevent moles? The short answer is no. Moles tunnel through property in search of food. Their primary food source is the earthworm, so even with a grub control, there is no guarantee that moles will stay away.
