fumigation

This term carries a clinical or industrial connotation when referring to the eradication of pests. It suggests a comprehensive, often invasive procedure where a space is sealed and saturated with toxic gases, evoking a sense of sterility and chemical intensity.

In a spiritual or historical context, the word shifts toward a ritualistic feeling. Here, it describes the use of fragrant smoke to cleanse a space, associating the process with purity, sanctity, and the sensory experience of incense rather than chemical toxicity.
