The Bifen Granules are not labeled for black widows or spider control in general and would not work for your needs. To control black widows or any other spider, you have to not only treat with the appropriate chemicals, like Cyper WP which comes in our Spider Control Kit, but also take the non-chemical steps of eliminating areas around the home that would be perfect living conditions for the spiders. You can see in our article How To Get Rid Of Black Widow Spiders, just what steps to take and where to look and treat to eliminate them from your environment. Please let us know if you have any other questions.
