White Grub Control

White grub insect damage can be extremely devastating resulting in extensive turf loss and costly repairs.

The European Chafer, Japanese Beetle, and the May/June Beetle are the most common white grub species that affect lawns across Canada.

White grubs live in the soil and feed on the roots of the grass plant causing death or intense stress that creates noticeable turf wilting. In many instances, damage to the lawn is severely compounded not only from the white grubs feeding on the grass roots, but from the animals such as raccoons, skunks, and birds that aggressively rip up, dig, and tear away at the surface of the lawn in an effort to feed on the white grub larvae themselves.

White grub infestations can often go unnoticed if grub populations are minimal or if the lawn is healthy and robust enough to withstand and outgrow the potential damage. Visual damage of animals digging is often the first sign grubs are present.

White Grub Life Cycle

Timing the white grubs life cycle is very important to ensure effective control and results. The damaging life stage of the white grub life cycle is during its larvae stage when it actively feeds on the roots. Control applications are carefully timed and applied during the grubs most vulnerable life stage to ensure effective control. The below picture illustrates the grubs life cycle.


White Grub Control Options

White grub control options may vary from Province to Province in accordance with pesticide regulations. It is important to contact your local Nutri-Lawn office to learn more about the control products available in your local market.

Nematode Grub Control

Beneficial nematodes applications are used to effectively reduce white grub infestations. Nematode applications are most effective when the grub larvae are very young and sensitive. Optimal application timing is late summer into early fall when the white grub is most vulnerable. Click here for more information about Nematode Grub Control.

Traditional IPM Grub Control

Synthetic pesticide applications are very effective at eliminating grub infestations. There are several product choice options that have a broad range of control across the grub life cycle. Most effective applications are typically made in June and July targeting the early instar of the larvae after the eggs have hatched.
