For decades, ultrasonic repellent devices have been on the market for control of rodent pests such as mice.To repel rodents, these devices produce high-frequency (15 to 19 kHz) or ultrasonic (19 kHz or more) sound waves.The theory of how they work ranges from causing fear, disorientation, and physical pain to mimicking alarm signals.
According to a 1984 study conducted by the University of NE, very loud sounds (120 to 150 decibels) can lead to seizures and even death in experimental rats.However, this level of noise can also damage people's ears and cannot be used to reject mice.Noise repellent is used more frequently in attempts to repel mice than humans can hear.The sound will also dissipate rapidly from its source.There is only one noise 2 feet from the source-Noise intensity 1 feet away from the source.At 4 feet, there's only one sound-Top 16.
Tests conducted in laboratory species such as mice and rats show that noise is more effective in repelling laboratory animals than wildlife.Wild Norwegian rats, for example, are only temporarily rejected by ultrasound devices, as reported in the University of neblas's 1984 study.They finally overcame their fear or fear of insect repellent and started their normal business.
Habit is a psychological term that refers to the "habit" of an organism to overcome fear or fear.This seems to happen when the ultrasonic repellent device is used to reject mice under normal conditions.The initial use of this device is usually successful in replacing mice, however, when they are used to noise, they overcome their fear of noise and may be re-usedLived in previously abandoned areas.
Humans can hear sounds at frequencies up to 23,000Hz (hertz.Researchers at the University of Louis Anna State reported that mice and mice were sensitive to sound up to 60,000 and 76,000Hz, respectively.However, regular pets like cats and dogs can also hear the frequency of ultrasound.Cats can sense sounds up to 64,000Hz, and dogs can sense sounds up to 45,000Hz.If you have a pet, you should consider not using noise as an insect repellent for mice.
News reports found that mice communicate with high-frequency sounds outside the range of human hearing.Ultrasonic Insect repellent may disrupt the ability to communicate by flooding the sounds of mice.Male mice sing an ultrasound mating song, and the ultrasound device may interfere with the reproduction of mice.Mice will also send out distress or alarm signals through ultrasound.Mice that accept an ultrasonic repellent device can interpret the sound as a distress or alarm call and leave the area.
