Abstract: An electrically activatable fumigating device and the method of its use. The device is adapted to be useable with vertically or horizontally oriented, wall-mounted electrical receptacles as well as receptacles mounted in horizontal countertops, all without the need for moving parts in the device. This is accomplished by the relative angle of the electrical plug to the longitudinal axis of a well contained within the body of the fumigating device from the mouth of which active ingredient is expelled by chemical reaction. Use of a modular heating assembly aids in allowing economical manufacture so that the fumigating device may be made inexpensively enough to be a single use device, with a self-disabling, single use, electrically activated heating means.
