Same product as the popular Victor Tin Cat Mouse Trap, for less! The Catchmaster Mouse Trap 612MCS is a live catch trap that is easy to use, catches up to 30 mice at a time, and requires no setting. Simply place the trap along a wall where mice like to travel and it is ready to go. Inquisitive mice will enter the trap, triggering a lever that will trap them in a holding area inside. They can get in, but there is no way out until you release them. Dimensions: 10.25 in x 6.25 in x 1.75 in.
