Since the Sevin Insecticide Granules do not have any herbicidal properties, you could apply grass seed anytime after applying the insecticide granules. We would just recommend that if you are going to aerate or do other soil modification, you probably will want to do that before applying your insecticide or wait until several days after so that you do not disturb the application.
