White Grubs

White grubs are the larvae of beetles. The larvae are white and all have six strong legs near the head. They vary in other characteristics such as size, head colour, and hair patterns on the body. These grubs feed on roots of various plants. Your garden plants, lawn and even potted plants can be attacked by grubs.

In general, white grubs have a one or two year life cycle, depending on the type of grub.

In Spring, the grubs are fully grown larvae and are actively feeding. In Summer, the grubs turn into pupae and pupate into beetles. This generally occurs around June in Canada. The beetles only live for about a week, mating and laying eggs which hatch a few weeks later. In Fall, the new grubs feed until temperatures drop when they burrow deep in the soil to avoid freezing. The grubs then emerge the following Spring.
