Dylox 6.2 Granular is recommended for when the grubs are actively feeding and will only kill for 48 hours after it is applied. Merit Insect Granules will work best if applied before the grubs hatch, so the best time of application is in the Spring but it's best to check with your local cooperative extension office to see what the best time of application is in your region.
