OWLTRA EMZ Plus Electric Mice Trap is the humane solution for getting rid of large populations of mice and rodents. The trap is equipped with dual entrances that allow mice and rodents to enter from either side of the trap, which ensures a maximum of two captures at the same time. Once one mouse/rodent is zapped on either end of the trap, after a 35-second wait period, the other side will automatically enter a standby mode and is ready to zap another mouse/rodent. It also has dual-infrared sensor that protects children and pets from accidentally triggering the trap. It generates 5000-8000 volts high-voltage shock for 120 seconds when rodents enter the trap for high rate of extermination. It is quick, humane, and safe.
