  • Patent number: 5392560
    Abstract: A simple three-piece insect trap for attracting and capturing flying insects consists of a hollow, opaque bait container having a neck with openings for admitting flies and a body for holding insect bait, a cone section mounted on the bait container neck for directing insects upward, and a transparent top cover mounted around the cone section for trapping the insects. The upper wall of the bait container body extends inwardly toward the neck of the bait container to form a shelf on which flying insects can land when attracted by volatile constituents which emanate from bait within the body. Moreover, an outwardly opening annular cavity is formed between the shelf on the bait container and the lower wall of the cone section, each of which are opaque to encourage flies to enter the neck through the apertures. When insects enter the aperture, they are discouraged by darkness from flying toward the bait in the opaque bait container.
