Qwesen Ultrasonic Pest Repellent Review

Review of the Qwesen Ultrasonic Pest Repellent

Unfortunately, the theory behind ultrasonic pest repellers is a bit shaky. It may seem like an eye-catching idea still, right? Plug this charger-sized device with unseeingly invisible sound into the wall, wait for about 2 weeks, and voila, your home and backyard are insect and rodent free without the use of toxic pesticides or vicious traps. Sounds great don’t you think.

These devices have never been verified to actually really work. But let’s take a look at the science behind it.

Qwesen Ultrasonic Pest Repeller waves have a higher frequency than what most human ears can perceive, however, the insects and rodents are able to detect them.

The emitted sound is meant to vex and irritate these critters while at the same time prevent them from inhabiting your home or anywhere close the source of the noise.

However, this only makes sense in science but in actuality, some of these animals seem to get accustomed to the noise and therefore they seem unbothered at all.

Qwesen Ultrasonic sound has a frequency of 32-62 kHz and can be reflected by solid surfaces and absorbed by the soft ones.

The scurrying pests and rodents find this sound very irritating and thus will try as much as they can to avoid these places.

This non-repetitive frequency causes discomfort that does not leave room for the rodents to become acquainted with the sound. Rodents can be very territorial and will continuously fight to establish dominance. The sound made by the dominant rodents will deject other pests from inhabiting the said territory.

For more effective rodent control, it is advisable that you use more than one ultrasonic unit in one room.

How the Qwesen Ultrasonic Pest Repeller works

Studies were conducted in laboratory conditions showcased that ultrasonic sound is indeed fatal to some species by increasing their body temperature.

The sounds emitted causes audiogenic seizures that results in convulsions, and possibly death from a cerebral hemorrhage.


The Qwesen Ultrasonic Pest Repels rodents by exposing them to extreme auditory stress. This is a classic animal behavior modification skill.

Ultrasound does not kill rodents unlike the traps and poison, however, it provides long term decrease in rodent population by creating a “pest- unfriendly” environment that deters rodent invasions.

Common mistakes people make with repellants

One of the most common mistakes people make is using the Qwesen Ultrasonic Pest Repeller units to control an already infested region.

Simply plugging in the Qwesen Ultrasonic Pest Repeller will not cause the rodents to run out in the cold when indeed there is still more food and comfort in your home.

Proper sanitation and exclusion techniques need to be incorporated also. Traps and baits should also come in handy.

Another common mistake is the poor placement of the unit. Ultrasound is reflected by hard surfaces therefore placing the unit behind the couch or refrigerator will cause the waves to bounce back and consequently creating a hostile noisy environment.

Identify the place invaded by the rodents by looking for signs such as fecal droppings, tracks, nests, and chew marks.

Subsequently, plug the Qwesen Ultrasonic Pest repel unit into an open space where the sound waves will not be blocked. The perfect spot would be one that allows the sound waves to cross the room without inference an example is the house entranceway.
