Grubs of Japanese beetle, European chafer, oriental beetle, masked chafer, June beetle and Asiatic garden beetle continue to be the most damaging group of insects to turf grass in Michigan.
 
Now is the time you will start seeing the June “bugs” beetles all over your porch and driveway. They are medium to large in size (8-25 mm) and are blackish or reddish-brown in color, without prominent markings, and often rather hairy ventrally. These beetles are nocturnal, coming to lights in great numbers. The adults are chafers, feeding on foliage of trees and shrubs. They may cause significant damage when emerging in large numbers. The larvae (called white grubs) feed on the roots of grasses and other plants. The insects pupate underground in the fall and emerge as adults the following spring. To test for the presence of these beetles, one can drench an area of lawn with a wet substance and the larvae will emerge at the surface. The adult beetles are very clumsy, both on land and in the air.
 
According to the Michigan State Extension office, grub control treatment is as follows:
 
March/April: Use curative such as Acelapryn.
 
June/July: Preventative such as Merit
 
August/September/October: Again use a curative such as Dylox,.
 
A curative will kill adult grubs and beetles. A preventative will kill young grubs.
