For how long after the initial application will normal watering, or a rain storm, reduce the effectiveness of the Bifen L/P Insecticide Granules in my lawn?
Once you have watered in the Bifen L/P Insecticide Granules and the treated areas have had to time to dry completely, rainfall and regular watering should not reduce the effectiveness of the product. In situations with frequent rainfall or frequent watering, you can reapply the product after 2 months.
