Ultrasound, which is defined by sound frequencies beyond the upper limit of human hearing, has been used as pest control only over the past few decades, however. The ultrasonic devices are plugged into a home's electrical receptacle outlets which then purportedly emit high-frequency sounds that are disruptive to pests.
Results: Fisher's test showed that there was the greatest repellency effect in both male and female at frequencies of 35 and 40kHz. According to the results of the regression test, the most lethal effect is at the frequencies of 40 and 75kHz.
Practical Tips for Using Natural Scents to Deter Insects
To effectively use these smells insects don't like, consider the following tips: Combine essential oils like citronella, peppermint, tea tree, and lavender to create your own bug-repellent spray. Mix with water and a little alcohol to help disperse the oil.
Ultrasound pest chasers are designed to repel pests from the home. Rodents respond to ultrasound with a frequency around 60 kHz. Cats and Dogs can be repelled using 22-25 kHz. Insects like mosquitoes, House fly, Fleas etc responds to 38-44 kHz.
Ultrasonic frequencies tend to be the most detrimental. They hate frequencies around 22-25 kHz US . Insects like Mosquitoes, Flies hate frequencies around 38-44 kHz.

Unlike bait traps, which capture pests where they are, ultrasonic repellent is used to drive pests away. Ideally, the high-frequency sound will make the pests abandon the area, leaving you pest free. The good news is that this sound is at a frequency above human hearing, so it's not distracting or annoying to humans.
While the idea of using high-frequency sound to deter pests is intriguing, studies have consistently shown that these devices have limited to no impact on most pests, including rodents and insects.
Some plants, like lavender, marigold, citronella grass, rosemary, and basil, naturally repel bugs. Lavender is particularly popular as a natural, people-and-pet-safe pest control plant. The aroma of lavender is too strong for small insects and discourages them from flying near the area.
Insects listen to, detect, and locate sound-producing predators, hosts, mates, and rivals, and they emit sound to attract, repel, or threaten members of their own species and to startle and evade predators.
Of the 12 bug repellents we tested, OFF! Active Insect Repellent earns our recommendation as the best option for most situations. We found the aerosol spray formula to be easy to apply, effective for several hours, and affordable. If you prefer a lotion, we suggest Sawyer Picaridin Insect Repellent.
Bugs naturally are attracted to vibrant colors such as orange, yellow, or white. Colours such as blue and green will not register as vividly when viewed in the ultraviolet spectrum, which deters bugs away from those colored items.
In a study, scientist have recently proven that certain electronic music can keep mosquitoes away (at least temporarily), stop them from biting you, and even stop them from multiplying. It's already a known fact that insects react to the sound waves produced by music.
An ultrasonic insect repellent work by emitting very high pitched sound — Ultra-fast sonics. Sound frequencies that repel insects and bugs typically runs somewhere between 35 and 45 KHz.
Ultrasonic pest control uses an electronic pest control device that emits a high-pitched sound at a frequency that can irritate, kill, repel, or incapacitate household pests, including bed bugs.
Bugs hate the smells associated with repellency, such as lavender, citronella, vinegar, peppermint, and geranium. These oils are considered a natural way of driving away bugs from your home without harming you, your family, and other animals.
If all else fails, drinking apple cider vinegar can actually have an effect on the smell of our sweat, making it less interesting for mosquitoes. As mentioned above, drinking cider vinegar can keep mosquitos away from you.
Thus when some studies show that pest infestations do decrease, they have no way of proving that it was a result of the ultrasonic sound. For these reasons, researchers strongly advise against buying into these devices. There is simply not enough evidence.
However, the question remains: Are these ultrasonic devices an effective pest control method? The answer in our experience: Sadly, no. There are several reasons for the failure of these devices for pest management purposes.
A little more about ultrasounds
They are directional, so they do not pass through walls. They bounce off hard surfaces and fill the room with sound pressure. A single device can protect up to 46 m2. As they do not pass through walls, you may need to use more than one device.
Not really; at most, they'll disturb pests temporarily. The idea is that pests will hear an annoying sound in your home and decide not to stick around. However, many pests like rodents and cockroaches are extremely adaptable to their surroundings and won't stay away for long (or at all).
There are electronic devices that emit high-frequency sound waves that act as cockroach repellents. These devices emit sound in the 22-65 Khz range which is inaudible to humans but can be detected by certain pests, including cockroaches.
