Today, one can often find advertisements for ultrasound devices that repel bugs and cockroaches using high-frequency sounds. So is such a method really a reliable way to get rid of these insects or is this another advertising ploy aimed at squeezing consumer wallets?
Ultrasound Exposure
Some insects are really dependent on ultrasonic vibrations, however, a small number of studies in this area do not allow us to state the degree of effectiveness of ultrasonic repellers used against cockroaches and bugs. Manufacturers of these devices claim that they emit sound waves that are unpleasant for the nervous system of cockroaches and bedbugs, forcing insects to leave a human home.
In addition to bugs and cockroaches, ultrasonic repellers are able to fight fleas and ants.
Ultrasonic repeller works when connected to power. It is equipped with a switch, which is set to look like a scared insect or rodent. According to manufacturers, the effectiveness of the ultrasonic device will be visible after a few days. As the impact of high-frequency sound on the nervous system of cockroaches and bugs, insects will begin to leave the house and will finally cease to appear after five to six weeks. For prevention, manufacturers recommend that ultrasonic repellers be left on for some time to prevent new insects from spreading in the house.
