In the video, a man is seen holding a small yellow and black mousetrap. He is wearing a white t-shirt with a bee and the words "Pest Control" written on it. The man is demonstrating how to set the trap by pressing down on the spring-loaded bar and then releasing it. He then shows the inside of the trap, which has a red and white striped flag that will be raised when a mouse is caught. The man's actions are deliberate and careful, ensuring that the trap is set correctly.
