The utility model refers to the field of electrical engineering, namely to devices intended for the transfer to the gas phase of insecticides.The fireproof fumigator contains a hollow body consisting of the upper (1) and lower parts, in which the electric plug (15) and the LED (12), connected in parallel with the shunt resistance (11), are fixed. Also inside the upper part (1) of the hollow body is a heating element (2) made of an electrically insulating heat-conducting material, with a technological depression (3) for the electric heater (4) fixed in this cavity with a mixture of silicate adhesive with sand (5). In the upper part (1) of the hollow body on the side opposite to the electric plug, a slit aperture (6) is provided for receiving a plate impregnated with the evaporating insecticide in the seat (7) adjacent to the heating element. In addition, the fireproof fumigator contains the screws (10) fixed to the heating element (2), on the side, opposite the technological socket (7) for the plate, on the side of the electrical plug (15), the thermal switch (8) with the manual reset button (9). The thermoswitch (8) is connected in series with the LED (12) and the electric heater (4) into a single electrical circuit soldered at its ends to the free ends of the wires (13) that are soldered to the electrical plug (15). Also, the flameproof fumigator can have a rotatable electrical plug. Also, a fireproof fumigator can have a timer circuit inside the casing with the possibility of setting the on and / or off times. In addition, a fireproof fumigator can have a fan inside the casing. Moreover, the fireproof fumigator may have a nest in the body from above and / or below in the form of a groove provided with a thread to fix the container with a liquid insecticide. from the side of the electrical plug (15), the thermal switch (8) with the manual reset button (9). The thermoswitch (8) is connected in series with the LED (12) and the electric heater (4) into a single electr
