Glue traps are devices of questionable morality used to ensnare and kill rats and mice. They have been banned in a couple countries.

>A 1983 test that evaluated the effectiveness of glue traps found that trapped mice struggling to free themselves would pull out their own hair, exposing bare, raw areas of skin. The mice broke or even bit off their own legs, and the glue caused their eyes to become badly irritated and scarred. After three to five hours in the glue traps, the mice defecated and urinated heavily because of their severe stress and fear, and quickly became covered with their own excrement. Animals whose faces become stuck in the glue slowly suffocate, and all trapped animals are subject to starvation and dehydration. It takes anywhere from three to five days for the mouse to finally die.

Luckily, our friends at Victor® have improved this torturesome device to eliminate all uncomfortable ethical concerns. Introducing the “No See” Glue Trap.
