Because granules can last longer than a liquid residual, we don't recommend reapplying Bifen L/P Insecticide Granules sooner than 30 days.Granules wouldn't be the best option because the granules will usually sink below the thatch layer. When treating for fleas, it's better to use a liquid insecticide, you can use Bifen IT. With Bifen IT, when treating for active fleas, you can re-treat every 14 days. A liquid insecticide is better because the residual will be in the soil, thatch and grass blades as well, offering a better residual. Once you have it under control, you can continue to treat every 30 days, especially if those around you are not doing anything to control the flea activity. Take a look at our Flea Prevention Guide, Step 3, for more tips for Outdoor Yard Flea Prevention.
