In a process for thermal pest control, a fuel-operated heater with separate flue gas routing is used to heat up a space to be treated. Fumigants may be additionally introduced into the air of the space to be treated, especially if the combustion chamber 13 of the heater is separated from the heat exchanger chamber 8 of the heater in a gas-tight manner. The process is particularly suitable for disinfecting mills and food-processing plants.

[ What is claimed is:] [1.]1. A process for disinfestation of a pest-infested enclosed space, the process comprising the steps of:providing a combustion heater generating exhaust flue gas;circulating air between the pest-infested enclosed space and the heater to heat the air in the enclosed space and increase a temperature of the enclosed space to above approximately 22 degrees Celsius while maintaining the air from the enclosed space separate from the exhaust flue gas;introducing sulfuryl fluoride into the enclosed space at one of before, during or after said heating of the air of the enclosed space.
