Abstract:
Apparatus for killing mosquitoes outdoors and in the neighbourhood of a building with an interior normally occupied by humans or animals, comprising in combination with an exterior wall of said building, said wall having an interior side exposed to carbon dioxide produced by humans or animals:a duct passing through an opening in said exterior wall, said duct having an inner end open to carbon-dioxide containing air on the interior side of said wall and having an outer end, a fan located for moving said carbon-dioxide containing air through the duct from its inner end to its outer end, exterminating means including an electrical grid connectable to a supply of voltage, said grid separating an interior space at the outer end of the duct from an atmosphere containing mosquitoes which surrounds said interior space and being such that when the grid is attached to the supply of voltage, mosquitoes are killed on attempting to pass through the grid; the apparatus being such that air containing carbon dioxide produced by humans or animals can pass from the inner end of the duct through the duct and into said interior space where it attracts mosquitoes to the grid for electrocution, and wherein said grid is disposed above a relatively unobstructed space to allow mosquitoes to fall freely away from the grid.
