Abstract
Abstract A portable electronic insect controller is provided wherein a electrified alternately polarized grid surrounds a light emitting region of a camping lantern. The grid includes a bottom and top ring spaced apart and substantially parallel to each other. Bars attached to the rings extend upward from the bottom ring and downward from the top ring in a spaced arrangement. A grid bracket includes grid posts which attach to the bottom ring and extend downward to engage a collar which extends around the outside of the lantern and is pulled securely against the lantern by buckle snap connectors. A base is provided onto which the lantern is secured and into which is housed a power source for electrification of the grid. The power supply steps up voltage from either a direct current source or alternating current source to a high enough voltage to arc across from one bar to the next when an insert enters the region between the bars. A safety interconnect strap connects the power supply and the grid carrying electrical energy to the grid. The interconnect strap overlays the filling spout of the lantern and must be removed prior to refueling of the lantern, thus preventing refueling while the grid is electrified. During operation a high voltage standing wave is alternately polarized on the bars and when an insect passes near the bars, the electric charge arcs between the bars and the insect, thus killing the insect.
