A composite vent has an elongated rectangular central panel with two narrower longitudinal rectangular side panels hingeably attached or detachably connected thereto, such that the side panels form a range of obtuse angles with the central panel. The reverse sides of the side panels contain one or more adhesive strips, such that the vent can be securely attached across the corner or side of a trash receptacle regardless of the size or shape of the receptacle or the angle at which the side walls of the receptacle meet to form a corner. The composite vent creates a vertical airway along the corner of side of the trash receptacle, such that air can enter at the top of the panel and flow down the sides of the receptacle and into the bottom below the liner bag. To prevent obstruction of the airway by the liner, the vent panel can be perforated at intervals along its length, and/or it contain a vent opening at its lower edge.
