Apparatus and method for killing mosquitoes outdoors and in the neighbourhoo d of a building normally occupied by humans or animals, has an electrical grid for killing t he mosquitoes and which is suitable for mounting adjacent the building and is connectable to a supply o f voltage, the grid separating an interior space, usually within the surrounding grid, from the atmosphere outside of the building, and being such that, when the grid is attached to a voltage supply, mosquitoes a re killed on attempting to pass through the grid. A duct connects the interior space to the interior of the building so that air containing carbon dioxide produced by occupants of the building passes throu gh the duct and into the interior space where it attracts mosquitoes to the grid for electrocution. Preferably, the apparatus includes a fan for pulling air containing carbon dioxide from inside the building through the duct and into said interior space.
