BAN CRUEL GLUE TRAPS NOW!The Case Against Glue Traps
A glue trap is a small board covered with a sticky adhesive designed to ensnare any animal who wanders across its surface. These devices inflict slow, painful deaths on mice, rats, birds, chipmunks, bats, lizards, squirrels, and any other animals small enough to get caught in the glue. They can take days to die of starvation, dehydration, or blood loss, while they cry out in agony. Take steps to outlaw these cruel traps!
