Multi Catch Mouse Trap is made from steel with a clear plastic viewing window. This non-lethal galvanized multi-catch mouse trap will quickly reduce rodent populations in homes, farms, warehouses, plants and businesses. Simply place the mouse trap on level surface, against a wall where mice are known to or are suspected to travel. As a mouse travels around the edges of a room, it will easily find your trap. The trap’s clear, see-through lid allows for easy inspection, letting you know how many mice are in each trap.
