  • Patent number: 5628142
    Abstract: An apparatus and method of attracting and trapping insects which includes an elongate strip of trapping material having a sticky substance thereon. In one embodiment, the trapping material provides a tubular trapping area. The trapping material is unwound from a feed roll across feed rollers to a take-up roller. The trapping area is provided between the feed rollers. The supply and feed rollers and take-up rollers may be contained in a cartridge which is disposable. The cartridge can be inserted in a housing having auxiliary components such as electrical components and lighting. The drive motor may be provided for automatically and intermittently advancing the take-up roller such that new sections of trapping material are automatically advanced into the trapping section, thereby maintaining fresh attractant substance exposed to insects.
