Pestbye Advanced Cockroach Repeller - Whole House Using modern electronic technology, the horror of cockroaches can now be overcome. How does it work? Dual technology: - Ultrasonic sound waves: Ultrasonic waves are high-pitched sound waves at frequencies too high for humans and most pets to hear. These ultrasonics are thought to be extremely uncomfortable for cockroaches and crawling insects, causing them to leave the room space. However, ultrasonics waves are like ordinary light waves - they will not penetrate solid objects such as walls and cupboards. Which means that ultrasonic devices can only be effective in the room you plug the device into, meaning that the cockroaches could hide in the walls, ceilings and in cupboards and behind curtains. Hence the second technology - electromagnetic waves. - Electromagnetic waves: Once plugged into any ordinary plug socket, the device sends electrical pulses through the wiring of your house. Whenever electricity passes through a wire, electromagnetic waves are created. Electromagnetic waves have been suggested to affect the nervous systems of cockroaches and are thought to be the main cause of them leaving your house
