Granules are an efficient and cost effective way to treat for pests in the yard. They provide long lasting residual control and help reduce a variety of insects, including scorpions. They are perfect for valve and meter boxes, gravel, lawns, bushes and shrubs, and even bare dirt. Most granules need to be watered after they are applied which "activates" them so they can start working on those pests! When handling any pesticide always refer to the label for proper precautions and usage.
