Ultrasonic Pest Control Side Effects for Humans & Pets

Some people report side effects such as tinnitus, headaches, dizziness, fatigue, and vomiting, but these individuals usually have sensitive hearing. Cats and dogs are generally not affected by the sounds, but domestic mice, hamsters, guinea pigs, and rabbits can show signs of distress. It’s true, having a pest problem is really annoying. One of the easiest solutions is to buy an ultrasonic insect repellent, but are they safe? What Ultrasonic Pest Control Side Effects for Humans & Pets?

It’s essential to familiarize yourself with ultrasonic devices’ advantages, disadvantages, side effects, and potential harms if you dislike chemical control and have no other option. It’s vital to note that these devices have been thoroughly examined and are safe for your health before we go into further depth. To learn more about this subject, however, you must read the complete essay because there is much more to learn.

The frequent pest control fallacies you may have tried in your home are also discussed below. You’ll also discover the effects a repeller may have on your dogs.

Is it safe to use ultrasonic pest control?

Yes, an ultrasonic rodent repeller is a safe product that won’t endanger your or your family’s well-being. There is widespread concern that ultrasonic sound waves could harm human hearing. Only sounds with a frequency of up to 20 kHz can be heard by the human ear. Repellents emit higher than 20 kHz frequencies. No scientific proof supports the claim that these gadgets cause harm or hearing loss.

This gadget is suitable for use around children and pets because it doesn’t contain any chemicals. Only bugs can hear the high-frequency noises that a repeller generates. There won’t be any harmful materials in your home that pets or kids could access. Pets can be an exception, but for the most part, they won’t even be aware that you’ve added a new gadget to your house.

Use of an Ultrasonic Pest Repeller: Risks and Side Effects

Some people avoid repellers because they believe they are unsafe, which is one of the main reasons for this decision. To dissuade you, we decided to provide a list of some implausible but potentially adverse consequences that people may encounter. Although there is no genuine health risk associated with using a device of this kind in your house, you should always be alert for symptoms connected to the presence of ultrasonic waves.


Although no concrete evidence links exposure to ultrasonic waves to these adverse effects, some people claim to have experienced them. The symptoms include persistent ringing in the ears, lightheadedness, nausea, headaches, migraines, sleeplessness, vomiting, dizziness, and more.

Even though these devices create sound waves above the human hearing range, those who are already sensitive to sound may feel some pain. Additionally, young people are more likely than older people to be able to hear high frequencies. Kids occasionally claim to be able to hear sounds nobody else can listen to.

You should contact your doctor if you ever experience any of these symptoms. The likelihood is that they aren’t adverse effects from using ultrasonic equipment, so you should determine whether there is another underlying medical condition.

The thing about ultrasonic repellers is that they have to pass a rigorous testing procedure before being made available for purchase. If a product doesn’t undergo stringent safety testing, it cannot be sold on the market. For this reason, you should always choose a trustworthy company that doesn’t market manufactured goods that could harm you.

use ultrasonic pest control mouse


If using an ultrasonic mouse repeller, some people may be concerned about how it would affect their cats, dogs, and other pets. These electrical gadgets are made to deter rats by making unpleasant high-pitched noises that the pests find repulsive. The majority of pets can hear sounds that are too loud for human ears; thus, they might be affected by these ultrasonic repellents just as much as unwelcome rodents are.

So how do cats, dogs, and other pets react to ultrasonic mouse repellers? Cats and dogs are generally not adversely affected by ultrasonic mouse repellers, but other domesticated animals like rabbits, hamsters, and some reptiles are.

Therefore, depending on the kinds of pets in the home and their personalities, pet owners should be aware of the consequences of these repellents before deciding to use them for pest control.

People use electronic pest control tools because they are safer for children and pets in the home and more environmentally friendly because they are non-toxic. Unfortunately, there isn’t much evidence to support the efficacy of these gadgets.

In addition, a lot of pet owners need to be made aware of how these repellents could affect other animals in the house. Therefore, this ultrasonic pest remedy may do more harm than good.

The Operation of Ultrasonic Mouse Repellers

Ultrasounds, high-pitched sounds produced by most electronic pest repellents, are meant to scare away insects and rodents. The volume at which they project the sounds and the frequency of ultrasonic sound ranges vary.

Ultrasound often refers to sounds with a frequency higher than 20 kilohertz. Although many animals can hear these high frequencies—most of which can listen to frequencies beyond 45 kilohertz—humans are not equipped to do so.

The idea behind an ultrasonic mouse repeller is that it would emit a sound that rodents could hear but humans couldn’t because of its high frequency. The perfect sound would be inaudible and safe for people, but it would frighten rodents and drive them out of the house.

However, the sound level produced by such a gadget and its frequency play a role in how repulsive it is. Common household pets like cats and dogs are often unaffected by the frequency of electronic insect repellents, but the volume can be alarming. Families with pets like rabbits and hamsters should also be aware of the harmful consequences that these repellents may have.

Reasons for Using Ultrasonic Mouse Repellents

The following are typical uses for ultrasonic mice and pest repellers:

  • They consider it more environmentally benign than other forms of repellants like poisonous sprays or chemical poisons and that it effectively controls rodents and other pests by keeping them out of the house.
  • When it comes to rodents, they think such repellents are more merciful than traps.
  • Since there is no exposure to poisons or pesticides, they consider it a healthier pest control method for families with pets or children.
  • The goals of individuals who employ these electrical repellents as a kind of pest control are responsible and compassionate. Humans, on the other hand, might not be aware of the effects these gadgets have on other animals in the house since they cannot discern the sound’s frequency or amplitude.

Humans would not be aware of the volume of such sounds since they cannot hear sounds at that frequency.

However, the noises must be transmitted at a specific book for the rodents in the area to listen to them and be deterred from approaching for the electrical repellents to function. Therefore, the frequency of these gadgets has a more minor impact on pets than their volume.

How Dogs Are Affected by Ultrasonic Repellents

Most companies that make ultrasonic mouse repellers assert that their products are safe for dogs. This is accurate because dogs aren’t bothered by high frequencies on their own, even if they can hear them. In reality, dogs are frequently trained and communicated using ultrasonic devices like dog whistles.

Canine pets in the home would most likely disregard the loud noises since ultrasonic mouse repellers would not be connected to a dog’s training or communication with its person. Nearly every day, dogs are exposed to ultrasonic noises, but they typically only respond to them if connected to human communication or training techniques.

Although the ultrasonic repellant devices’ frequency might not impact dogs in the house, their volume most definitely can, especially on anxious dogs. Dogs typically respond in one of three ways when exposed to such repellents, according to users:

  • Leaving the area where the noise is coming from (anxious behavior)
  • Unusual behavior with the device (head tilting, sniffing)
  • disregard for the audio or gadget (minimal or no reaction)

Although these reactions don’t suggest any significant harm or discomfort to canine pets, ultrasonic repellents have the potential to annoy and upset dogs who live in houses where they are employed. Before using such repellents, pet owners should speak with their veterinarian and keep an eye out for any signs of suffering in their dogs, as each dog responds differently.

Dogs use body language to express how comfortable they are. Distress manifests itself in:

  • I made a U-turn and started running the other way.
  • Stepping back
  • tucking the tail
  • barking or whining

Additionally, these gadgets should not be used where dogs spend time, especially when eating or sleeping. Owners of dogs should stop using the ultrasonic mouse repeller as soon as they realize their canines are acting nervously or under more stress.

How Cats Are Affected by Ultrasonic Repellents

Manufacturers of ultrasonic mouse repellers assert that their products are safe for cats and dogs. Compared to most canines, cats can hear more sounds at higher pitches, between 55 and almost 80 kilohertz.

Felines don’t communicate with humans using their ultrasonic hearing as their canine counterparts do. However, since many rodent species have ultrasonic cries, they probably use their excellent hearing for hunting.

Cats might become upset when things change in the house since they are so sensitive. Additionally, cats dislike loud noises, which can also cause emotions of annoyance and anxiety. This article has appeared on wikipests.com. Thus, the presence of a high-pitched ultrasonic frequency would not necessarily hurt cats on its own—but the sudden and continuous volume of the noise might negatively influence a companion cat.

By their very nature, cats may be harder to predict how something will influence them than dogs. Cats communicate by body language, just like dogs do. Their responses, meanwhile, can sometimes be far less blatant and obvious. Indicators of cat distress include:

  • urinating outside of their litter box
  • improper or persistent scratching
  • Diarrhea
  • Hiding
  • Clinginess
  • a diminished appetite
  • Extraordinary grooming

Many of these distress indicators in cats are also clues to health problems. Therefore, cat owners should report the behaviors and seek medical guidance from their veterinarian before presuming that turning off the ultrasonic repellant will fix the issue.

How Rabbits Are Affected by Ultrasonic Repellents

Rabbits, especially those kept as indoor pets, are adversely affected by ultrasonic mouse repellers. Even when tamed, rabbits are naturally wary and vigilant because they are predatory animals. They are more prone to anxiety and panic than other animals since their senses are easily aroused. They are also far more vulnerable to stress because of this.

Clear indications of stress in rabbits include:

  • Excessive trepidation and jitteriness
  • Restlessness
  • abrasive or challenging behavior
  • Lethargy
  • Extreme excitement, grunting, or shrieking Lack of appetite Rapid breathing and/or panting
    swollen or terrified eyes
  • Thumping or stomping their feet Hair pulling resulting in bald patches and/or a thinning coat
  • Ears pushed back against their head
  • Repetitive motions, including bobbing, biting, and circling

Rabbit naturally

Rabbits are naturally anxious creatures, but changes in their environment might make them more vulnerable to stress. Mainly abrupt alterations may set off their stress response. As a result, owners of pet rabbits must take extra care to ensure their well-being.

Rabbits rely on regularity in their environment and find comfort in routine and habit. Any modifications should be made gradually.

Rabbits also have exceptionally acute hearing and are constantly alert to sounds around them. As a result, they are highly distressed by loud noises. Once more, when it comes to ultrasonic mouse repellers, the volume rather than the frequency of the noises puts rabbits at risk for anxiety.

While producers of ultrasonic repellents advise users not to use them if they have rabbits in the house, some specify that the tools can be used in areas where pet rabbits don’t hang around. This is misleading because of the abrupt change in sound that the device would bring into the house and its potential volume for sensitive rabbit ears.

Therefore, rabbit owners should avoid using ultrasonic pest control devices because of the abrupt environmental change and potential volume.

Effects of Ultrasonic Repellent on Other Domestic Animals

The three most popular home pets are cats, dogs, and rabbits. Other domesticated animals are, nonetheless, kept as pets in many homes. These include fish species, birds, rodents, amphibians, and reptiles. The potential adverse effects of ultrasonic repellents on indoor animals should likewise be known to these pet owners.

Pet Rodents

Potential family pets, including all rodent family members, include chinchillas, hamsters, guinea pigs, and gerbils. Ultrasonic mouse repellers shouldn’t be used in houses with mice kept as pets because they are made to deter rodents. Such animals living in the home may find the noises created uncomfortable and stressful.

The makers of this pest management technology are aware of these scenarios and advise against employing them.

Pet Amphibians

Frogs can also hear ultrasounds; some species even employ them in communication. There have yet to be many investigations into whether amphibians are negatively impacted by ultrasonic pest control equipment exposure. As a result, it is preferable for people who own pets that are amphibians, such as frogs, to carefully consider utilizing such repellers.

Pet reptiles

Many households choose to keep reptiles as pets, including snakes and lizards. Snakes primarily “hear” through vibrations; hence ultrasonic frequencies of any volume would not impact them. Snakes cannot hear as well as lizards, and lizards are susceptible to the effects of ultrasonic mouse repellers. Some ultrasonic pest control equipment is advertised for removing geckos and lizards from homes.

Therefore, ultrasonic mouse-repellent devices in houses with pet snakes would be acceptable. However, due to the harmful consequences of the ultrasounds, they shouldn’t be utilized in households with pet reptiles other than snakes.

Avian pets

Birds’ hearing talents are comparable to those of humans. Thus, most birds couldn’t hear ultrasounds in their surroundings. Even though birds and humans both hear best at frequencies close to one another, birds are more sensitive to the tones and rhythms of sounds to help them stand out.

Most anecdotal and scientific evidence suggests that ultrasonic pest repellers wouldn’t adversely affect pet birds in homes. Owners of birds should be aware of any indicators of stress, such as feather issues and aggressive behavior, and seek the advice of a trained veterinarian if necessary.

Pet fish

Many people are unaware that fish rely on hearing for sociability and health and that loud noises are harmful to them. As a result, even when kept in an aquarium or tank, they are sensitive to the number of ultrasonic pest repellents, just like many other pets.

Fish’s health and behavior will very certainly be harmed by ultrasound exposure. The experience is compared by scientists to repeatedly subjecting a dog to a dog whistle. Therefore, fish owners must consider any potential harm ultrasonic mouse repellers could do to their aquatic creatures.

Environmental stressors affect all living things and can harm their physical and mental health. Household pets are exposed to pressures humans have created, many of which they are not physically equipped to handle. An example of a stressor created by people is an ultrasonic mouse repeller.

Most animals use hearing as their second most important sense, after scent, to comprehend and react to their environment. Humans should be aware of these impacts since any interruption or environmental change that affects an animal’s hearing is likely to result in reactions ranging from mild annoyance to incapacitating stress.

Affected by Ultrasonic Repellents

Manufacturer of ultrasonic repellents claims

Most ultrasonic mouse repellent producers assert that their products are safe for dogs and cats to use inside the home. However, they include warnings that forbid users from placing repellers next to rodent-family pets like hamsters and gerbils.

Unfortunately, many of the manufacturer’s claims are based on anecdotes and/or “in-house” studies rather than being supported by independent research. The few independent investigations that have been done show that the majority of ultrasonic devices are only minimally effective.

We wrote a piece regarding the effectiveness of ultrasonic pest repellents here. This can result from the positioning and range of the devices inside the house or the fact that rodents can gradually get used to the sounds.

Therefore, rather than solely relying on product claims, consumers of ultrasonic mouse repellents should assess their suitability as a pest control strategy and any possibility of pet suffering. Pets can still be affected by sounds in a home even while humans can’t hear them, especially if the sounds are loud enough to be heard by them.

Ultrasonic Repellents’ Overall Effectiveness

People would look for alternative pest management strategies like ultrasonic repellents as more people become aware of the adverse effects that pesticides and toxins have on the environment.

This is particularly true about rodents and the possible cruelty of various pest management methods. Ultrasonic mouse repellers are thought to be humane and environmentally friendly.

Contrary to what is claimed by the products themselves, however, individual accounts and independent studies indicate that these repellants need more success. Therefore, the best action for pet owners regarding ultrasonic mouse repellers is to rely on other pest control techniques, given the diversity in actual pest control effectiveness and potential consequences on pets.

Pet owners should be aware of the risks of pest management to other animals living in the house. Responsible pet owners should ask their veterinarians for advice on effective pest management methods, use them as instructed to reduce risk, and keep an eye on their animals for any behavioral changes.

When animals live in a home and have little to no influence over their surroundings and how it changes, stress can be just as destructive to them as it is to people. Since animals can only communicate with people through body language and behavior, pet owners must recognize distress signals in their animals and take the necessary measures to alleviate the situation.

The introduction of ultrasonic pest control tools is part of this mitigation. While some pets might not care about the difference in volume, others might get tense, nervous, or unhappy. Pet owners are responsible for ensuring their animals’ well-being, including being aware of elements that may adversely affect their standard of living.
