A method of eliminating, reducing or preventing bacterial contamination of a surface, the method comprising dispersing a bacteriophage containing composition in air in proximity to the surface. In some embodiments, the bacteriophage containing composition is a powder dispersed by pressurizing a load chamber containing the powder so that the powder is expelled through an outlet. Also, devices for performing the method and a powder used in the method.
