You are bidding on a 4 pk Glue Traps - Mouse killer !
How to use: open and place them along the borders in the room or where you suspect or see mice running. Common places for where to put these traps for example would be behind the refrigerator or stove. If you have a basement or "downstairs" it would be a good idea to put boards there, as it could catch not only mice, but also Spiders, Silver Fish and other insects, preventing them from coming upstairs.
Tips: For the best results in catching mice, put a piece of chocolate in the middle of the board. Mice LOVE chocolate!!! If you are trying to catch Water Bugs, I suggest putting either barley or sour moldy bread in the center of the board.
