Adonis 75 WSP is labeled for ants and when used as instructed on the product label will do a great job eliminating this pest. Adonis 75 WSP is not labeled for spiders so we do not know if it would be effective for spider control. We recommend using a product such as Demon WP or Cy-Kick CS for spider control.
