They circulate in the air, moving with the air currents, some falling on the surface of objects, floors, walls, ceilings and furnishings. They drift indoors through the air-handling system, open doors or windows and drop off people and materials coming into the building. The most effective strategy to prevent damage to objects and to prev...
