CPV code 90670000 designates Disinfecting and exterminating services in urban or rural areas in the Common Procurement Vocabulary (CPV 2008), the EU classification used to describe the subject of public contracts.
90670000 is a leaf code — the most specific level of its branch — so it can be used directly as the main CPV code of a contract notice. If it does not quite fit, check the neighbouring codes under 90600000 (Cleaning and sanitation services in urban or rural areas, and related services).
