The present invention relates to a method for protecting the lower regions of and structure of a building (10) from damage or degradation by termites. The method comprises the steps of creating a region in the ground below the building having properties hostile to termites whereby to discourage them from approaching the vicinity of the building. In one embodiment means for creating a hostile region in the ground below the building are provided by a pump (12) which creates a superatmoshpheric pressure field (40) in this region. Treatment agents (31) such as ozone may be delivered to the ground region in order to provide a hostile effect to the termites by affecting their pheromone chemistry and/or their reproductive or communicative behavior. A secondary function of the present invention relates to the creation of a forced ventilation (46) of the habitable region (18) within which the apparatus of the present invention resides.

The system includes a plurality of scent control material sources configured to output a scent control material (e.g., an oxidant) into the environment to reduce pathogens, dispose of scent molecules and their sources, and otherwise treat the environment. The system can include a controller communicatively coupled to the plurality of scent control material sources and cause one or more subsets of the plurality of scent control material sources to individually or collectively output scent control material into the environment.

A method and system of generating ozone gas. The method comprises receiving a stream of ambient air that includes at least oxygen gas, generating ozone gas based upon applying ultraviolet (UV) irradiation provided in accordance with a wavelength of 185 nanometer (nm) to at least a portion of the oxygen gas, the UV irradiation provided via an optical lamp module powered by a direct current (DC) voltage battery source, producing a modified air stream in accordance with the generating, and exhausting the modified air stream, the modified air stream having a higher concentration of ozone gas as compared with a trace concentration of ozone gas that is constituted in the stream of ambient air.
