- 1). Lay one cardboard piece on the ground, then place three wooden strips the same length as the cardboard on top of it -- two on opposite sides of the cardboard and one in the middle. The wooden pieces should be parallel to one another.
- 2). Lay the other cardboard piece on top of the wooden strips and first piece of cardboard. Make sure that the two pieces of cardboard are lined up with each other.
- 3). Fasten the two cardboard pieces to the wooden strips by pressing down on each of the wooden pieces a few times with a staple gun. This will create a sandwich-like stink bug trap. The bugs will be drawn to the tight spaces and shelter of the trap.
- 4). Lean the trap against the side of your home and check on it after about 24 hours.
- 5). Pick up the trap slowly after it has collected the insects, empty it into a garbage bag, tie the bag tightly and dispose of it. Alternatively, you can empty the trap into a bucket of ammonia water to kill the insects instantly.
