When is the best time to apply preventative grub control in southeast Ohio?

The best time to apply preventative grub control in southeast Ohio is during the early spring just before the grubs hatch. Putting down insecticide in late spring is futile; full grown grubs do not eat as much. If the early spring application is missed, wait until late summer to apply.

Adult beetles flying around is a signal to put down the preventative grub control product. To check for grub problems, pull back a square foot of turf or soil from an area in the yard. Six or more grubs means signals a grub issue. Irrigation after the application of grub control is essential, the insecticide then sinks deeper into the soil reaching the grubs.
