Hi-Yield 55% Malathion Insecticide Spray is not labeled for spiders so would not be recommended. We do have a great Spider Control Kit that includes CB-80 Aerosol Insecticide for contact spraying, and Temprid FX, which can be applied indoors as a crack and crevice or spot treatment. This kit also contains glue boards, which are excellent tools for monitoring and for catching stray spiders indoors. Please see our Spider Treatment Article for more information and tips about preventing spider infestations.
