An insect trap 1 comprising a high pressure air source to force air through a carbon dioxide adsorbent material contained in a pressure vessel 5. The temperature of the adsorbent material can be controlled with a heater 7. An inlet valve 4 and an outlet valve 8 of the pressure vessel control the airflow though the trap. CO2 enriched air is subsequently passed through an attractant diffuser 10 which is situated near to a powered bladed fan 11. Air and insects are subsequently forced into a filter element 14. Air passes easily though the filter element while insects are trapped. The carbon dioxide adsorbent e.g. zeolite adsorbs, collects and releases CO2 in response to changes in pressure and temperature. |
