An electronic insect zapper.
When I leave the backdoor open in the evenings for the dogs, these *&%#@?/#@&%* "flying legs" insects come inside. I have a strategically placed patio chair just inside the kitchen door.
To activate it, you press a button and a red light comes on. The directions tell you not to touch the wire screen when the light is on. You know I had to do it. Small ouch was all.
This zapper really works! What a cool gizmo! LOL! I love it!
