An apparatus (10) for killing flying insects comprises an open framework (12) having a lower portion (14) adapted to be located under ground level so as to define an in-ground enclosure, and an upper portion (16) which is adapted to be located above ground level and is continuous with the lower portion. The lower portion of the open framework includes a mesh (20) to prevent collapse of the ground around the enclosure. The apparatus (10) also includes means (24, 26) for spraying controlled amounts of insecticide into the in-ground enclosure, and a lid (22) for covering the top of the upper portion. In use, flying insects, such as sand flies and mosquitoes, may gain access into the in-ground enclosure by entering through an opening (28) in the open framework at the sides of the upper portion, and any such flying insects within the in-ground enclosure are killed by exposure to sprayed insecticide.
