The Wilson SpiderOut Ready-to-Use Spider Spray provides fast and effective control of spiders both indoors and outdoors. The 1-L spider-repellent spray utilizes permethrin for long-lasting spider knockdown and residual activity. Its quick knockdown formula targets spiders on contact while residual permethrin keeps working to kill spiders for weeks after application. The ready-to-use formulation means no mixing or diluting is required before spraying. Wilson SpiderOut Spider Spray Outdoor offers an easy and efficient solution for controlling spiders inside the home or around exterior walls, fences, and landscaping.
