Treating for grubs can often vary from region to region and can change with the weather you have each season. It is best to apply your grub control products like the Merit 0.5 G in mid-June to mid-July before the grubs hatch. The eggs hatch in the fall, and grubs feed on turf in the fall, overwinter underground, and then feed again in the spring. You will see damage during both of these seasons. For more specific timing for your area, we would recommend contacting your local county extension office. We also have a treatment guide with more helpful information on grub control.
