The Wind-Up Multiple Catch Mouse Trap is an enclosed system with a clear inspection window and catches multiple mice with no bait needed. The clear inspection lid makes it easy to monitor this trap and empty or clean as needed. Simply wind the side handle seven times and capture multiple mice as they enter the trap looking for harborage. Catch large numbers of mice and keep them alive for a more humane or sanitary mouse trap. This is the perfect trap for large infestations and traps mice in individual compartments to keep them alive for later release or sanitary disposal. Made of galvanized steel, this trap is fully enclosed for child and pet safe pest removal.
