Unfortunately, Niban Granluar Bait is not labeled for spiders. When treating for spiders you want to look at two things that you can control: their habitat and their food source. We recommend you remove all the webbing that is in the area, and use a product like Transport Mikron to spray that would get rid of all the other pests that are in the area which is the spiders food source. While the Niban will control crickets, silverfish, ants roaches, and snails and slugs, it is not labeled like the Transport for a large variety of pest that are most likely in the area that are still a food source. You would need to eliminate their entire food source so that they will go look elsewhere for that. Transport Mikron is also labeled to treat for spiders as well should they actually come in contact with the product residual.
