Dylox 6.2 Granules are only active and kill for 48 hours, so grubs also need to be active in the area at the time of application. It is best to apply when you see turf damage from the grubs actively feeding. This time frame is normally from July to September. Application timing is very important and it varies from region to region. We recommend you contact your local cooperative extension office and speak to the master gardener on staff as he or she will be able to give you the most accurate information in regards to application timing in your area.
