Lo Line Traps are made using a synthetic adhesive applied to a cardboard base. A tablet lure can be placed in the center of the Lo Line Trap to entice the cockroach to enter the trap where they are then caught on the adhesive base. Lo Line Traps are used primarily for cockroach control indoors. Lo Line traps are not effective outdoors due to environmental conditions (moisture, dust), which quickly render the adhesive ineffective.
