ABSTRACT:
An insecticide dispenser capable of initiating the volatilization of a charge of insecticide to fumigate a room. The dispenser includes a container for the insecticide that is disposed upon a PTC heater. One side of the power supply necessary to initiate the chemical reaction passes directly through the cannister to the PTC heater. The other side of the power supply is connected through a support upon which the PTC heater rests. In the preferred embodiment, an electrical cut-off device is included in the circuit which will turn off the power when a predetermined temperature is attained which will be indicative of the initiation of the self-sustaining chemical reaction that causes the dispensing of the insecticide into the room.
