The Scotts Moss Control Granules for Lawns does not have any reference on the product label to there being a restriction time on when you can put down grass seed. Typically we suggest giving 1 week after an application before putting down seed since the moss/algae needs to have time to die back and expose the soil below it. Grass seed needs to make direct contact with soil to take best so you should be safe after that time frame. If you have more questions regarding timing you can reach the manufacturer Scotts at 800-543-8873.
Scotts Moss Control Granules For Lawns should not harm wildlife when applied as directed. We would recommend applying when they are not in the area and when there is a few hours for it to dry before they return.
