when should i spread insect granules
Yes, the Sevin Insecticide Granules can be applied when the grass is wet. Watering the Sevin granules in is what activates the granules. If it is going to rain close to the time you are applying the granules that will be fine too. Failure to water in the granules can lead to treatment failure because the chemical cannot be released from the granule and will not be available to the pests.
