This disposable trap has a unique feature. You activate the mouse trap with the red lever. The mousetrap has its own bait, but you can also apply bait on the top. The mouse walks in through a bend and falls into the trap. As soon as the fall is triggered, the entrance closes and you see the lever jump up. For you, this is the indication that the trap is filled. The fall is completely closed. You can throw it all in the container with a mouse. This trap is designed so that you can catch mice effectively without having to see or touch the mice
