A person whose job is to perform fumigation, or a device that produces smoke or gas for disinfection.
From 'fumigation' plus the Latin agent suffix '-tor' (one who does), creating a word for the active performer of the fumigation process.
Professional fumigators today use high-tech equipment and carefully measured chemicals, but in the 1800s, they were basically walking around with burning sulfur pots—a job that came with serious health risks.
