No, Bifen Granules are not labeled for any type of spiders. We would recommend using Onslaught FastCap Spider and Scorpion Insecticide. It is labeled for various types of spiders, as well as other pests. You will need to spray in the areas where the spiders are. They need to come in contact with the product in order for the spiders to die. This can be used indoors and outdoors.
