Are Grubs Destroying Your Lawn?

Many people are discovering that grubs, the larvae of some beetles, can destroy your lawn if not detected early and treated.

Although the most common destructive grub in Canada was originally from the native June bug, recent introductions of the Japanese beetle and the European chafer within the Niagara region have resulted in their migration further east and north in Ontario, causing havoc to lawns in eastern Ontario.

Adult June bugs are a shiny red-brown color, reaching up to 1 inch in length.  The Japanese beetle is much smaller, less than 1/2 inch long, with a metallic bronze and green color.  An adult European chafer is similar in size to the Japanese beetle, but tan or light brown in color.

All of these grubs have c-shaped bodies and six legs, however, the June bug larvae are white, while the larvae of the Japanese beetle and European chafer are a beige color. Upon hatching the grubs are tiny but reach a mature size of up to 1.5 inches.

Another major difference between the types of grubs is that the June bugs take 3 years to mature while the Japanese beetle and European chafer only take one year.  As a result, infestations of white grubs (June bugs larvae) happen every third year, while infestations of the other two types can happen annually.
