Shoreline Mosquito Defense’s All-Natural Mosquito Spray is a botanical solution to keep your family comfortable. Our trained and certified technicians always begin by inspecting your property, eliminating active breeding sites, and applying larvicide where applicable. We then apply an eco-friendly insecticide made from rosemary and peppermint essential oils. This natural formula effectively repels and eliminates mosquitoes while leaving a pleasant minty scent that fades within just 1 to 2 hours.
