An access structure 10 for use in trapping flying insects comprises a lid member 12 having a horizontal top portion 24, an access opening 26 in the top portion, and a downwardly depending tubular wall 28 defining a downwardly open passage 30 leading from the access opening. A cover member 14 which is spaced upwardly from the top portion 24 forms a roof over the access opening 26. Between the top portion 24 and the cover member 14 there are four vanes 32 which extend radially from the access opening. In one embodiment the top portion is provided with a skirt portion 34 having formations 38, which enables the structure to be screwed onto a glass jar. In use, an insect attractant is placed in the jar. This attracts insects, which enter the jar via the access opening 26 and the passage 30, are unable to find their way back through the access opening, and eventually die in the jar. In another embodiment a trapping container having a perforated bottom wall is connected to the access structure, and a bait holder is connected to the bottom of the trapping container.
