White grubs are a widespread problem in Quebec. The following are a few tips to help control these small insects: Aerate your lawn through core aeration and dethatching.
Apply an EFFICIENT fertilizer.
Leave the grass long when mowing (8 cm or 3 inches). Attract blackbirds and starlings, which like to feed on the grubs. A lawn care professional can apply a MERIT treatment, which will kill newly hatched grubs and prevent the grubs from coming back the following year.
