Insect trapping apparatus
View Patent ↗An insect trapping apparatus and associated method attracts insects, such as mosquitos, by emitting a carbon dioxide gas as an insect attractant and producing a heat signature from the insect trap characteristic of a warm blooded animal and a blue light of a wavelength that attracts insects into the insect trap. The carbon dioxide gas is exhausted together with moisture through a vertically extending exhaust tube to minimize cooling of the carbon dioxide gas and minimize condensation of moisture while attracting insects through an inflow channel of an insect trap to trap the insects therein.
1. An insect trapping apparatus comprising:
a combustion and exhaust device comprising:
(i) a first housing;
(ii) an exhaust member; and
(iii) a gas burner mounted within the first housing for receiving a combustible gas and generating hot carbon dioxide gas and moisture through the exhaust member, the exhaust member having an outlet open to atmosphere for permitting the carbon dioxide gas to flow outwardly therefrom, the outlet of the exhaust member being positioned on a first vertical axis; and
an insect trap assembly comprising a second housing having an inlet, an insect trap communicated to the inlet, and a vacuum generator operable to draw an inflow of air from outside the second housing into the inlet for drawing insects into the second housing for capture in the insect trap, the inlet being positioned on a second vertical axis,
said insect trap assembly and said exhaust member being positioned offset from and entirely exteriorly of one another with the inlet of the insect trap assembly and the outlet of the exhaust member also positioned offset from and entirely exteriorly of one another, wherein the first and second vertical axes are offset from one another;
wherein said insect trap assembly comprises an air intake wall extending around at least a portion of said second housing to form an inflow channel defining said inlet; and
wherein the second housing is round and the inflow channel is annular.
2. An apparatus according to claim 1 , wherein said combustible gas comprises propane.
3. An apparatus according to claim 1 , wherein said insect trap assembly is supported by said exhaust member.
4. An apparatus according to claim 1 , wherein said insect trap assembly is spaced offset from said exhaust member to minimize any cooling effects of the inflow of air on the hot carbon dioxide gas.
5. An apparatus according to claim 1 , and further comprising a ground engaging stand supporting said gas burner and said insect trap assembly above the ground.
6. An apparatus according to claim 1 , and further comprising a catch cup supported by said insect trap assembly into which the inflow of air is passed and into which insects drawn by the inflow of air become trapped.
7. An apparatus according to claim 1 , and further comprising a heater panel in said insect trap assembly for producing from said insect trap assembly a heat signature characteristic of the temperature of a warm blooded animal.
8. An apparatus according to claim 1 , wherein the insect trap assembly is mounted to the exhaust member by a mount mounted to an exterior surface of the exhaust member.
9. An insect trapping apparatus according to claim 1 , wherein said first housing is substantially cylindrical.
10. An insect trapping apparatus comprising:
a combustion and exhaust device comprising:
(i) a first housing;
(ii) an exhaust member connected to the first housing; and
(iii) a gas burner mounted within the first housing for receiving a combustible gas and generating hot carbon dioxide gas and moisture through the exhaust member, the exhaust member having an outlet open to atmosphere for permitting the carbon dioxide gas to flow outwardly therefrom, the outlet of the exhaust member being positioned on a first vertical axis; and
an insect trap assembly comprising a second housing having an inlet, an insect trap communicated to the inlet, and a vacuum generator operable to draw an inflow of air from outside the second housing into the inlet for drawing insects into the second housing for capture in the insect trap, the inlet being positioned on a second vertical axis,
said insect trap assembly and said exhaust member being positioned offset from and exteriorly of one another with the inlet of the insect trap assembly and the outlet of the exhaust member also positioned offset from and exteriorly of one another, wherein the first and second vertical axes are offset from one another;
wherein the insect trap assembly is mounted to an exterior surface of the combustion and exhaust device.
11. An apparatus according to claim 10 , wherein the exterior surface of the combustion and exhaust device is an exterior surface of the exhaust member.
