It is recommended to read this article carefully to the end before making any payment for the purchase of an insect and vermin removal device!

Can an ultrasonic device really drive away insects and vermin?

For some time now, electric devices that drive away insects and vermin have been widely advertised on television and cyberspace, and their manufacturers and importers claim that the device, by emitting supersonic sounds, drives away all kinds of insects. Pests (either rodents or insects) from the infected place or even the death of insects and rodents. These devices are called ultrasonic pest repellents, which are offered to customers in different countries of the world under the name or brand and in different forms.

These mouse repellent devices work by creating sounds with short wavelength and high frequency. The frequency created by these devices is more than 20,000 Hz, which is basically referred to as infrasound. The companies that supply these equipments usually falsely write in their advertising brochures that the sound created by the device can only be heard by insects and mice and is very annoying for them so that they either leave the place or die.

Ultrasonic pest repellers are electronic devices that generate high-frequency sounds to repel or destroy household pests such as rodents and insects, of course, it is worth noting that insects and rodents learn how to It has passed itself behind the sound barrier so that they do not have any hearing problems, so it will not cause any eradication and destruction and is nothing more than advertising.

The United States Federal Trade Commission (FTC) considers the effectiveness of the ultrasonic device to be ineffective.


lets review the details of some advertisements of insect repellent device sellers :

  • Can be used in large halls, warehouses, farms, factories and restaurants
  • Effective Area: For outdoor space up to 8000 square feet (about 2500 square meters)
    The system of sterilizing insects and vermin and preventing them from laying eggs is aimed at eliminating insects permanently.  (really ? nonsense)
  • Device to remove animals, birds, vermin, rats, mice, pigeons, cockroaches, bees, mosquitoes, bed bugs, fleas, spiders, etc.


They declare the performance of this device in terms of removing mice (Mice & Rat), cockroaches, scorpions, bats, ants, bees, flies, spiders, mites, worms, termites, bedbugs, fleas, millipedes and crickets, if there is no root It will not cause damage and destruction, and after some time the customer complains about the device not working.

They claim that the device is designed for homes, villas, stores, warehouses, workshops, hotels, restaurants, confectioneries, factories, industrial kitchens, restrooms, public places, etc., but after purchasing, most of the customers expressed their dissatisfaction. they announceThis device has the approval of America and Europe and has no effect on the physical and nervous mechanism of humans in any age group and all types of pets such as dogs, cats, fish, birds, etc., if this case is not more than a claim and in Now it has been declared obsolete in other countries.

In fact, the sounds that can be heard by the human ear are in the frequency range between 20 and 20,000 Hz, which means that the frequencies outside this range cannot be recognized by humans, because the eardrum due to the impact of these sounds at a sufficient speed and required to create Hearing stimulation does not vibrate. But animals such as dogs, bats, and rodents hear sounds in the infrasound frequency range.

Insects such as locusts hear sounds in the frequency range of 50 to 100 kHz, and insects such as moths and membrane wings hear sounds up to 240 kHz. Of course, the fact that some insects have the ability to feel supersonic sounds cannot lead to the conclusion that they have the ability to kill them or make them escape from the target location. actually they dont even care about those sounds

The studies that have been conducted regarding the effectiveness of the ultrasonic pest control device show different results. In an extensive test conducted by Kansas State University in 2002, these devices were found to be completely ineffective at repelling many insects, such as crickets, and effective against insects such as cockroaches, bed bugs, ants, and spiders. It has not in any way. Of the pests that seem to be bothered by the waves, some experiments have shown that they quickly get used to the waves because they realize that the waves are harmless and easily pass through the sound barrier. so as not to damage their hearing.

Before buying an insect repellent device, please contact the Vice President of Health and Medical Affairs of the University of Medical Sciences, Department of Environmental Health and make sure whether these sellers are approved by the Ministry of Health or not. Do they have supervision in these companies or not?

Basically, sound plays a very important role in the life of insects. Sounds are mostly responsible for the role of a physical mediator to establish intra-species communication. Also, insects may use their hearing power to identify enemies such as bats and other insectivorous creatures. In any case, regarding the effect of these devices on insects, it can be said that their repelling effect on this category of pests has not been proven so far.

The Federal Trade Commission, which is responsible for protecting consumers of goods and services in the United States of America, on May 3, 2001, sent letters to 60 companies that sell these devices to fight insects in the United States. The United States emphasized that they should refrain from including terms such as having scientific support in the announcement of this organization regarding what is written about the effect of these devices on controlling insects and rodents in the advertising brochures of the manufacturing companies: The manufacturer of this device is not compatible with the FTC Act (prohibiting false and misleading advertising).

The research conducted at Louisiana State University regarding the effect of animal repellants on bed bugs and German cockroaches, or tiny cabinet cockroaches, also indicates that the repellants of this device do not affect these insects. In this study, three ultrasonic devices with different characteristics (in terms of output frequency and SPL) were used. According to the authors, the obtained results indicate the inability of this device to remove bed bugs and German cockroaches, and the researchers have not been able to provide sufficient scientific evidence regarding the effect of the removal and destruction of these insect repellent devices on German cockroaches and bed bugs. and get other insects.

Recently, the companies producing the devices are selling poisons to their customers in addition to selling the seemingly repellent device, and on the other hand, it is interesting to know that in their advertisements, they consider the use of poisons in homes as dangerous, and this duality shows that this device It does not work for you in any way!
