Abstract: An insect lure and trap system includes a valve that receives a gaseous fuel, and provides a regulated flow of gaseous fuel. The regulated flow of gaseous fuel is input to an exothermic reactor that generates carbon dioxide to attract insects to a predetermined region, where a generated airflow forces insects within the predetermined region into a container. A temperature sensor senses the temperature of the carbon dioxide and provides a carbon dioxide temperature signal indicative thereof to a controller, which generates a valve command signal that regulates the valve in response to the carbon dioxide temperature signal. Advantageously, operating closed loop on catalyst temperature (i.e., gas temperature measured at the catalyst) allows for a more efficient use of the fuel, which is used to generate the CO2 attractant.

Abstract: An insect attracting and killing device employs a translucently diffused light source to attract insects and operates in conjunction with a fan-driven air flow to draw the thus attracted insects inwardly into contact with an electrically charged grid.

Abstract: A portable liquid sprayer has a tank adapted to contain a supply of liquid received through a fill opening, an a pump for pressurizing liquid contained therein. A first spraying mechanism includes a first control valve carried on the tank and a first nozzle removably connected to the tank. A second spraying mechanism and a second nozzle form part of a wand assembly located at one end of a flexible hose. The hose has a coupling at the opposite end adapted to be interchangeably connected to the tank in the place of the first nozzle. The first control valve has a valve seat included as an integral component of the first nozzle and without which the first control valve is incapable of preventing the flow of pressurized liquid therethrough from the tank.

Abstract: An insect killing device has an electrically powered light source surrounded by an electrically conductive grid, the light source and grid being enclosed within a dielectric housing having a side wall which is closed at its upper end by an impervious top and which defines an open port at its lower end. The light source and the grid are energizable by an electric AC power source external to the housing via electric circuit components located in the housing. The side wall has an array of openings through which insects attracted by the energized light source may pass to come into contact with and be electrocuted by the energized grid. The grid is supported on a dielectric carrier and is separably connected to the electric circuit components.

Abstract: An apparatus for attracting insects to an insect trapping device. The apparatus includes: a source of combustible fluid; a burner communicating with the fluid source for igniting the fluid in an exothermic reaction generating carbon dioxide, moisture and heat; and a catalyst for catalytically sustaining the reaction.

Abstract: An electrical grill assembly for use in a device for electrically exterminating insects, comprising inner and outer generally cylindrical metal grill members which are held in a coaxial mutually spaced relationship by insulator spacers interposed therebetween. The insulator spacers are structurally interlocked with the grill members at least partially by means of oppositely extending protrusions which are integrally formed on the spacers and which are received in radially aligned openings in opposed portions of the grill members.
