Water lawn after application to wash granules from the lawn foliage. If the soil is not moist, it is important to irrigate before application. Control will be optimized by combining broadcast application that will control foraging workers and newly-mated fly-in queens with mound treatments that will kill existing colonies. Mound Treatment: Apply half a cup per mound. If the soil is not moist, it is important to irrigate before application. After applying the product, drench the mounds with 1-2 gallons of water.
