Electronic cockroach killers trap cockroaches in a contained area. Electronic cockroach killers are reusable and do not require much electricity per use. This is a high-tech and environmentally friendly method of killing cockroaches that does not use chemicals, therefore does not run the risk of second-hand contamination. Correct use of the cockroach killer is the difference between the device working effectively and not completing its task.
Clean up all possible cockroach food supplies around the house, including open food sources and crumbs. This increases the likelihood of the cockroaches finding the baited trap.
Lift the top hatch and place the bait inside the cockroach killer. Place the device in an area where you've noticed a lot of cockroach activity. Cockroaches can be sneaky making their moves when nobody is around, so if you have not noticed a specific area favored by the cockroaches, place the trap near a possible food supply from which the cockroaches might be feeding.
Position one end of the device, so it makes contact against the wall. Connect the trap to the battery holder power supply, so the power indicator turns on. This device can be used as a cockroach catcher by not connecting the power supply and then connecting it later to kill the cockroach with electricity.
Remove the power supply and clean the bodies out of the catcher every four days. Remember to reload the catcher with bait as needed.
