Abstract: An insect killing system has a blower drawing air entraining insects from below a vacuum machine, impelling the air upward, a flange oriented horizontally at an outlet to the blower, and a killing assembly affixed to the flange. The system is characterized in that the killing assembly comprises a plurality of panels of a common width, having an upper edge, a lower edge, and opposite side edges defining an area for each panel, the area closed by a relatively thin perforated sheet material exhibiting a matrix of through holes, individual panels affixed by the bottom edge to the flange on opposite sides, with each panel oriented by a steep angle from vertical, with each panel in the plurality parallel to and spaced apart from one or more adjacent panels, such that the area defined by an inside diameter of the flange is covered by the plurality of adjacent parallel panels.

Abstract: A bug-removal vacuum machine has a horizontal deck, and a structure providing a trapezoidal-shaped air passage directing insects drawn by vacuum-induced air flow through an electrified killing matrix, and into a collection tray.

Abstract: A vacuum machine has a rectangular deck, having a centerline, a width and a length, an underside and an upper side, a front edge and a rear edge, and side edges. Sidewalls extend below the deck along the side edges. There is an opening through the deck, substantially centered between the front edge and the rear edge, and between the sidewalls, a powered air blower coupled through a plenum above the deck to the opening, such that operating the blower draws air through the opening from beneath the deck, a killing mechanism disposed at an outlet from the blower, adapted to kill insects entrained in air drawn through the plenum, and a horizontally-oriented passage coupled to the outlet from the blower, directing air having entrained insects dead or alive away from the machine. The machine travels in the direction of the centerline advancing the first front edge of the deck.
