Abstract
A method of selectively destroying organisms within a predetermined area is comprised of the steps of introducing vapor phase hydrogen peroxide into the predetermined area at a rate sufficient to cause a predetermined concentration of hydrogen peroxide to be reached while preventing any substantial change in pressure or condensation of the hydrogen peroxide within the predetermined area. The predetermined concentration is maintained for a period of time sufficient for destroying undesirable organisms but insufficient for harming desirable organisms. When the predetermined period of time has elapsed, the vapor phase hydrogen peroxide is removed from the area.
