Abstract: A pest collection-disposal device includes a means for establishing an air stream in an air duct forming at least a segment of a housing for the device. Positioned in the duct is a disposable pest collection cartridge. The cartridge comprises an elongated body having a flexible closure means and a filter means. The closure means deflects under the influence of an air stream from a closed position to provide an entrance thereto for insects entrained in the air stream. The filter means separates insects from the air stream. Upon termination of air flow, the flexible closure member is restored to an initial position to entrap the pest between the flap and filter means. The duct in one embodiment includes an expandable and retractable array of elongated telescoping members. In a further embodiment, the cartridge is positioned in one of the elongated duct members.
