We do not recommend using Medina Orange Oil for spider control. Orange Oil is not a pesticide nor is it labeled for any specific insects. While it may slightly deter some insect pests, it will only kill those insects that are sprayed directly during application. If you are looking for a "natural" type of product, we would recommend something like EcoVia EC for more effective spider control.
