Welcome to Grub Talk, ladies and gentleman, a weekly educational series on the life and times of the notorious white grub. Also known as the European Chafer beetle, May/June beetle, or Japanese beetle, the white grub can be found in many lawns across Canada, and is a pest that can tear up even the strongest of lawns if left untreated.
Most homeowners don't know that white grubs are present until they suffer significant turf loss from secondary pests, such as animals who feed on the grubs and cause damage. The key to success with white grubs is identifying that they are present before any turf damage is visible, so monitoring early and often is the best practice!
The life cycle of the white grub consists of 4 stages: Egg, Larvae, Pupa, and Adult. During this 4 stage process, the white grub transforms itself in shape, size, colour and feeding habits. It also changes where it lives during its life cycle. White grub species all complete their life cycle in 1 year, with the exception of the June Beetle, which has a 3 year life cycle.
