Pest control technicians and exterminators are often used interchangeably to refer to professionals who work to control or eliminate pests from homes, businesses, and other properties. However, the term “exterminator” may specifically refer to someone who specializes in the extermination of a particular type of pest, such as termites, or who uses more aggressive methods to control pests, such as fumigation. In general, the term “pest control technician” may be used to refer to anyone who works to control or eliminate pests, regardless of their specific methods or areas of expertise.
