These are non-poisonous and ready-to-use, disposable glue traps. To use separate the Stick-Em Glue Traps along the scored hinges and place lengthwise glue side up against wall or wherever mice are known to travel. Stick-Em will trap them when they try to run across the tray. When Stick-Em Glue Traps are used in dusty areas, lean a board against the wall and place the traps between the board and the wall. To attract rodents more quickly, place peanuts in the center of the trap. Place at 5 to 8 foot intervals.
