The Hi-Yield Bug Blaster II Bifenthrin Granules do need to be activated with rainfall or irrigation, but you should not apply the product while it is raining or when the ground is completely saturated. If you have several consecutive days of rain, then it would be better to wait until the rain has stopped and the ground is not water-logged to apply the product, then you can activated it with 0.1 - 0.5 inches of watering immediately after application.
