This invention relates to methods and apparatus for achieving microbiological control, especially using active sources that generate hypochlorous acid vapor with reduced levels of chlorine vapor. These methods are effective in confined spaces and sealed containers. The active sources may be contained within permeable containers and may be actively dispersed. The active sources may be in the form of solids, liquids or gels.
