Is rainfall or watering necessary within 24 hours?
Since Merit Insecticide Granules is a systemic insecticide that translocates through the plant, it is best applied before Spring/Summer egg hatch, before we see adults and/or damage from the target pest, in this case before we see adult mole crickets. The granules do need to be activated with irrigation or rainfall of about 0.5 inches. For the most exact recommendation as to when to apply the product, we recommend contacting your local Cooperative Extension office.
