  • Patent number: 4044494
    Abstract: A trap for flying insects and bugs, particularly of the relatively small varieties such as mosquitoes, sand flies, gnats, etc. The trap generally comprises a housing defining an interior chamber, one or more of the walls being slotted with inwardly turned, converging flanges along the slot edges. The inner edges of the flanges are provided with a fabric tape of a material such as nylon with inwardly directed frayed warp strands in a manner so as to permit the entry of the flying insects and bugs into the chamber while preventing their exit therefrom. The housing is fabricated of a clear transparent material to reflect light into the interior chamber and, in addition, a reflective material may be applied to some or all of the flanges.
