    Patent number: 5384981
    Abstract: Disposable glue traps for catching rodents such as rats or mice are formed by sheets of folded paper or cardboard each provided with a glue layer. Each folded sheet has a self-adherent tear-away border so that a trap forms its own packaging, thereby dispensing with the need for separate outer packaging materials.
