To establish a firm argument on the functionality of these devices, it is important to highlight the major points in a concisely,
Results from studies conducted show that the public is currently disclosed in their houses with no authorization to use ultrasonic devices.
These recommendations come almost five decades after thorough research, only to be considered null and void, the reason being that, the research’s outcome was built upon incorrect proof.
Later, this evidence was outweighed after different organizations from many countries took on newer guidelines. Therefore, presuppositions that underpin both physical measurements and audiology at frequency higher ought to be.
There are also additional essential question on the functionality of the ultrasonic that ought to be established, for example;

Ultrasonic pest repellent devices use effective technology that employs waves of exceedingly high frequencies above the range of human hearing.
In hypothesis, the shaking of this electronic pest repeller brings about an emotional reaction that in turn affects insect pests in your house.

Does that mean that ultrasonic rodent control is a hoax?

Besides, there is still no evidence that the device has caused hearing damage to the human ear or injury of any kind.
The sound produced by ultrasonic at adequate pressure level normally extremely irritates rodents. And when it comes to humans with hearing sensitivity, they can easily cause damage, mainly if it is not audible enough.
In whatever way, even such devices designed for human safety may be a nuisance and cause harm to your pets and other animals, mostly because of their high-frequency sounds.
Such ultrasonic waves in these devices are because they emit airborne ultrasounds.
These devices are indeed safe for humans; however, there is no evidence that they function to all intents and purposes.
Recently, ultrasonic pest repellers advertised as cautious environmentally friendly, more so when kicking pests out of your home.

Some rodents and pests can hear frequencies that are below 100kHz. You ought to, therefore, keep in mind when purchasing the device. Though it is a pest control method, the frequency should at least be higher than your pet can hear.
Animals and other pesky critters by nature hear high-frequency sound waves in the much higher range and are considered best in chasing small insects and pests.

The common pros are;
With or without a sensitive hearing, human ears can detect frequencies that go all the way up to 20kHz with no damage to the ear whatsoever, unless the ultrasonic sound waves have a high-frequency range. then this may cause severe adverse effects.
