Per the product label for Spectracide Triazicide Once & Done Insect Killer Concentrate when treating for surface insects you would want to delay watering for 24 hours after application. For subsurface insect control (mole crickets, grubs), you would water the treated area with additional 1/4 to 1/2 inch of water after application for optimum results.
