Although these devices is effective against pests, there are also concerns about whether it is safe to use them around pet birds.

Do pest repellers affect birds?

Ultrasonic repellers do not affect birds immediately.

Ultrasonic repellers made to affect pests like rodents and insects, but these repellers emit high-frequency sounds that are mostly inaudible to birds. Birds and other pests hear different frequency ranges, so it’s unlikely that a bird’s hearing range will include ultrasonic waves.

But, there are ultrasonic repellers specially crafted for birds, in case you are looking to chase some birds off your lawn. Ultrasonic bird deterrents are effective against woodpeckers, pigeons, and sparrows that frequent your farm.

How does ultrasonic Pest repellent affect pet birds?

According to research birds hear best in the frequency range of 1 to 4 kHz.

Although there are differences between different birds, no species can hear sounds higher than ultrasonic frequencies (>20 kHz). Even high-pitched songbirds can only detect frequencies of 20 kHz, while species such as oil birds and swiftlets can only operate between 1 and 15 kHz.

Since the hearing ability of birds is similar to that of humans, ultrasonic insect repellent will not negatively affect your birds.

However, depending on your bird species, high-intensity and loud noise may damage their auditory receptors. Continuous exposure to these noises may cause permanent damage to their hearing. Therefore, if you use an ultrasonic insect repellent at home, watch your birds and check for any signs of stress or abnormal behavior.

If your birds are sensitive to these devices, you may need to use them in lower amounts or consider other pest control options.

What Are Ultrasonic Pest Repellers?

Ultrasonic pest repellers are pest control measures that repel pests by producing sound waves of high frequency and short wavelength. These sound waves operate beyond the range of human hearing and sound above and below the human audible range, making it impossible to perceive. This is because the audible range for humans differs from that of animals.

This technology frustrates animals’ senses without a perceptible effect on humans.

In other words, this technology is eco-friendly and can be safely used. It works on mice, rodents, and pest insects.

So many professionals have maintained one specific stance: all unwanted pests and rodents can never tolerate the sounds made by these devices.

For this reason, they must vacate any area blanketed by these noises.

However, it would help if you understood that it is important to research the effectiveness of these ultrasonic pest repellers before you think of investing in these devices.

Not to worry, the next sections clarify the controversy about ultrasonic repellers and show you if they truly work or not.

Are Ultrasonic Sound Pest Repellers Effective?

Often, Do-It-Yourself (DIY) pest control comes with its downsides because you might end up spending more cash than you should while trying every means to control these pests. To minimize cost, it is important to understand how pest control works before solving a pest problem by yourself.

Are Ultrasonic Pest Repellers Safe for Pets?

Many ultrasonic pest repellers give off sounds above 20 kilohertz (kHz). This noise level could be unbearable and unsafe for certain kinds of pets.

For instance, mice, rats, guinea pigs, hamsters, and other pet rodents can withstand sounds up to 90 kHz. A cat can perceive noise up to 60 kHz, and a dog can hear sounds up to 40 kHz.

While most household pets can hear sounds over 20HZ, you should still measure their reaction when exposed to the continuous ultrasonic sound emitted by pest repellers. We say this because, just like in humans, overexposure to continuous high-pitch sound can prove harmful and cause certain neurological disorders to pets.

At this juncture, it is important to mention that there has been no proven study to support the claim that ultrasonic devices can pose long-term neurological damage to dogs. This means we can conclude that ultrasonic pest repellers are safe for dogs and pretty much pet rodents.

Moreover, many homeowners have used it, and the testimony is positive. Nonetheless, if you keep pets, it would be best to discuss these devices with your veterinarian before you purchase them.

How to Use Ultrasonic Pest Repellers?

Ultrasonic pest control products adopt sound waves with high frequency to repel mice and rats by creating an unpleasant environment for them. The beauty of ultrasonic pest repellent is that it can prevent a rodent infestation before it begins.

Besides, unlike chemical repellents, these devices are non-poisonous, eco-friendly, and safe to use around children and non-rodent pets. They are imperceptible by anyone but rodents.

Here are three tips to keep in mind while using the ultrasonic pest repeller:

1. Identify the infected region

The first thing you have to consider is identifying the room with signs of pest activity.

Speaking of signs of infestation, some of the things to look out for are small tracks, little droppings, rodent nests, gnaw marks, etc. But it would be best to inspect at night since rodents are nocturnal animals, i.e., most active at night.

Once you identify any sign of rodent activity, the next step is to plug this unit into an outlet that opens up to the rest of the room. While hard surfaces reflect ultrasound, you must know that soft surfaces absorb it.

When your room is filled with hard surfaces, ultrasound bounces around, making the use of this device more effective. A good placement should allow sound waves to cross in front of an entranceway.

2. Use multiple Units

Ultrasonic sounds behave more like light waves than sounds.

Let me explain.

When you play music in your house, it can cover your entire house, and the wave can travel across rooms. However, ultrasonic sounds cannot penetrate solid surfaces, much like light, and Similarly, they cannot travel around corners. This makes it important to consider using multiple units for your home.

The rule associated with square footage coverage is basic: an ultrasonic pest repeller will only cover where they are set to cover. For instance, you need more than a single unit to ensure effectiveness, say in a room that is 200sq large.

3. Combine with other pest control methods

An ultrasonic pest repeller should not be used alone to manage infestations to get the best result, and you should use them with other pest control methods like baits and traps. Maintaining proper hygiene and other efforts would also help repel these rodents.

Are Ultrasonic Pest Repellers Harmful to Humans?

Now, we have established that ultrasonic repellers effectively control pests, and we also stated that repellers are harmless to most household pets. However, it doesn’t just stop there, as you need to consider your safety as a person.

Certain rumors about these ultrasonic devices have been flying around that are harmful to humans.

But these are just rumors.

High-frequency sounds are imperceptible and harmless to humans, and they are not associated with any health issues, except when some are very sensitive to them.

As established earlier, using an ultrasonic pest repeller is eco-friendly, and this implies that you can use them around kids since it has not been proven that these devices are harmful to kids.
