A new host-attractant trap constructed from a CDC miniature light trap is described and compared to CO2-baited CDC light traps and lard can bait traps. The unit is inexpensive to construct and run is self-contained, portable and can easily be converted back to a standard CDC. When baited with house sparrows, the trap was found to catch significantly more Culiseta melanura than the CDC + C02 and significantly more Cs. morsitans than either of the other trap types.
