PEST CONTROL DEVICE
Two glue boards shipped as a sandwich, sliced apart with a knife.
Two rigid panels are pressed together with a non-drying adhesive between them, and U-shaped plastic brackets crimp the four edges to keep the adhesive from creeping out during shipment. The user pulls off the brackets and runs a knife through the adhesive layer, splitting the sandwich so each panel keeps half the glue. The exposed panels are placed where rodents frequent. A rodent stepping onto a panel adheres to it and remains there.
“The rodents and pests caught by the boards usually die from dehydration after a short period of time and the boards can then be discarded.”— Nathan Kosinsky, from the specification
And the world did not beat a path to his door.
