Direct answer
Thermal insecticidal fogging is a defined term in the International Fire Code (IFC) 2009, in Fumigation and Thermal Insecticidal Fogging. The code's own words are: “The utilization of insecticidal liquids passed through thermal fog-generating units where, by means of heat, pressure and turbulence, such liquids are transformed and discharged in the form of fog or mist blown into an area to be treated.” No other I-Code in this corpus defines it, so the IFC 2009 definition is the one to work from. The term is used in 3 chapters of this corpus, most often in Fumigation and Thermal Insecticidal Fogging (IFC 2009), Scope and Administration (IFC 2009), Definitions (IFC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.
