  • Publication number: 20020129540
    Abstract: An apparatus is provided for collecting insects comprising (i) a source of propane, (ii) a propane burner arranged to combust propane from the source of propane so as to produce carbon dioxide and water vapor as products of combustion for attracting insects, and (iii) an insect collector located in proximity to the propane burner for collecting insects attracted to the propane burner. The use of a propane burner provides the desired products of combustion including carbon dioxide and water vapor as well as heat for mimicking the breathing of animals to attract biting insects using readily available propane tanks. The convection of heat from the propane burner is further beneficial because a flow of carbon dioxide and water vapor through the collector may be achieved without the additional requirement of fans or any other complex arrangement of parts. The collector may comprise an electrical grid which does not require a light for attracting insects as do conventional electrical grids for pest control.

  • Patent number: 6134826
    Abstract: A compact insect trapping appliance uses an efficient ultraviolet light mounted from underneath a protective dome to both attract insects and to enable the user to position the appliance to selectively direct the ultraviolet light in a desired direction, away from a line of sight of people near the appliance. The inner walls of the upper, partially open chamber carries a low voltage grid array for deleteriously affecting and disabling insects which alight on the inner walls of the upper chamber. This low voltage grid array produces a low voltage current, and acts fairly slowly and silently to disorient and disable the insect as it makes contact. Once the insect gets becomes sufficiently disabled, it will likely fall directly into, or by its own movements, slide into an entry hole of an conical surface and through a narrow neck of a sound suppression chamber within the appliance.

The apparatus generally includes a source of carbon dioxide, a source of octenol, a device for emitting the carbon dioxide proximate the source of octenol to create a mixture of the carbon dioxide and octenol, a heating element and an electrified grid. Insects are initially attracted to the apparatus by the odor associated with the mixture of carbon dioxide and octenol. As the insects fly closer to the apparatus, they are further attracted to the visual properties of the apparatus and then, at close range, they are attracted to the heat emitted by the heating element. In an attempt to fly closer to the heating element, the insects are intercepted by the electrified grid and destroyed.

  • Patent number: 6050025
    Abstract: An insect killing system optimized for mosquitoes uses multiple thermal gradients to simulate the breathing and body heat from animals, including human beings and fowl, to attract insects for subsequent electrocution. The system comprises an elongated, generally parallelepiped housing supported upon a lower base. A heating tower shrouded by the housing supports a spaced apart, generally pyramidal roof. Several slits penetrate the base to permit air entry. An internal fan draws air into the base where the air mixes with scent and pheromones. Mixed air is blown into and through the heating tower. An internal baffle divides the tower interior into separate, spaced apart compartments. A lower compartment houses a heater, and an adjacent upper compartment vents warmed air to atmosphere, creating numerous separate streams of warmed air that, to an insect, emulate human breathing. The baffle restricts air flow to create a pressure differential while ensuring adequate residence time to sufficiently warm the air.
