Grubs And Grub Control


White grubs may be the most damaging turf insect pests in the United States. According to the U.S. Department of Agriculture, Japanese beetle grubs alone cause an estimated $234 million in damage each year — $78 million for control costs and an additional $156 million for replacement of damaged turf

White grubs are the larval stage of many different beetles, including the Japanese beetle. The grubs live below ground and feed on the roots of tender grass plants that soon will eventually kill the plant. They are most destructive mid-late summer, but the damage they cause may not show up until early fall and by then, it's too late.

The best time to control grubs is in early summer (June and July), just after they hatch. At this time they are very susceptible to treatment and just before they start causing extensive damage to your lawn.
