A barrier spray is a coating of pesticide sprayed onto foliage surrounding an area that has been inundated by mosquitoes. While it does not kill mosquitoes, it repels them, and adheres to the underside of the foliage, depriving them of their resting places. When our inspectors are unable to locate a treatable source of mosquito breeding, and a homeowner is surrounded by tree canopy where mosquitoes like to rest, the inspector may resort to using a barrier spray to provide the homeowner some temporary relief.
