The invention relates to an insect trap 10 and more particularly to an insect trap which has been designed to facilitate the destruction of micro-organisms thereby countering odours and mitigating against the spread of germs. The trap comprises a housing 12, a cover (14, fig 2), one or a plurality of insect attracting lights 16 and an insect catching means (18, fig 3) and further comprises a UVC lamp 20 which emits radiation (or other means) which is capable of destroying air-borne pathogens. The insect attractant lamps heat the air which is convected as a consequence of louvered openings (26, fig 2) in the cover and an opening (30, fig 3) in the top 28 of the trap and circulate across the UVC lamp where the micro-organisms are killed.
