What's the difference between pest control and an exterminator?

The difference between pest control and an exterminator is mainly about approach, scope, and long-term prevention, though the terms are often used interchangeably by the public. An exterminator traditionally focuses on exterminating or killing pests that are already present using chemical sprays and pesticides, with a short-term goal of eliminating visible infestations quickly, for example spraying for cockroaches or ants on a one-time visit without addressing why they came. Pest control, especially modern integrated pest management or IPM, focuses on both eliminating existing pests and preventing future infestations through a comprehensive, long-term strategy that includes inspection, identification of pest species and entry points, sanitation recommendations, exclusion by sealing cracks and gaps, moisture control, targeted use of baits, traps, and low-toxicity products, and ongoing monitoring with quarterly visits. Pest control technicians are often more trained as pest management professionals who consider environmental factors and use multiple tactics, while exterminators may rely primarily on chemical sprays. In practice, most reputable companies today, including Orkin and Terminix, call themselves pest control companies and use IPM methods, even if customers still call them exterminators. Pest control also tends to include guarantees, free re-treats between visits, and education about prevention, whereas an exterminator might just spray and leave. So exterminator implies immediate killing, while pest control implies killing plus prevention and long-term management for lasting results.
