What does fumigator mean?
A fumigator is an apparatus designed to generate and spread pesticidal fumes or smoke through an enclosed space, killing insects, rodents, mould, or other unwanted organisms; the term can also denote a person who carries out this work professionally. Fumigation has ancient roots — smoke from burning sulphur or herbs was long used to disinfect rooms, granaries, and ships — and the modern fumigator mechanises that old idea, delivering chemicals such as sulfuryl fluoride evenly into greenhouses, warehouses, and tented houses. The word belongs mainly to the technical vocabularies of pest control, agriculture, and public health, so encountering it usually signals a professional context. It pairs closely with 'fumigant', which names the substance being dispersed, while the fumigator is the tool or operator doing the dispersing. Understanding this distinction makes the term easy to place: one supplies the poison, the other delivers it.
An apparatus used to produce and distribute fumigating vapours or smoke in order to destroy pests or disinfect a space.
"The warehouse installed an automatic fumigator to keep grain weevils out of stored stock."
In trade contexts the device is often simply called a fogger or fogging machine.
A person whose work is fumigating buildings, ships, or other premises.
"They called in a certified fumigator after finding dry-wood termites in the attic."
The plural follows the standard -or pattern; note that some writers drop the terminal -r, giving 'fumigatores' in older Latin-influenced usage, but 'fumigators' is the normal English form.
"Two fumigators worked through the night to clear the hotel of bedbugs."
The word traces back to Latin fumus — 'smoke' — because for centuries the standard way to rid a room of pests was simply to smoke it out.

Etymology of fumigator
Fumigator derives ultimately from the Latin verb fumigare, meaning to smoke or expose to smoke, built on the noun fumus, 'smoke'. The English noun emerged in the early nineteenth century alongside the growth of scientific pest control and public-health sanitation, when purpose-built apparatus for generating disinfecting fumes came into use. It shares its root with the related forms fumigate, fumigation, and fumigant, as well as more distant relatives such as fume and perfume, both of which likewise descend from Latin words connected to smoke and vapour.

How fumigator is actually used
The word is largely confined to pest-control and agricultural contexts, so it reads as technical rather than everyday vocabulary. In common speech, people more often name the profession ('pest control worker', 'exterminator') than use 'fumigator' itself.
