do ultrasonic pest repellers affect birds

Ultrasonic pest repellers have become a popular and humane option for homeowners looking to safeguard their properties from various types of pests. However, there are concerns regarding their safety towards non-target species, particularly our feathered friends—birds.

Based on extensive studies and scientific literature, the consensus is that these devices are generally safe for birds, but understanding why involves a deeper dive into the functioning of ultrasonic repellers, the hearing range of birds, and the possible impacts of these devices on bird behaviour and physiology.

In this article, we, at Bon Accord Pest Control, aim to provide an in-depth analysis of the subject to help you make an informed decision for your bird-friendly pest control needs.

Understanding Ultrasonic Pest Repellers and Bird Physiology

The way in which ultrasonic pest repellers work is by releasing high-frequency sound waves, usually between 20,000 and 65,000 Hz. The basic idea is that certain pests, like arachnids, insects, and rodents, find these frequencies extremely irritating and are discouraged from living in or passing through the area the device covers. Because of the limitations of our auditory range, humans and the majority of pets are unable to hear these frequencies, which makes them an effective means of controlling pests.

When considering birds, their hearing range is quite different. The majority of bird species can hear sounds between 1,000 and 4,000 Hz, while some can detect sounds as high as 20,000 Hz. This indicates that most of the ultrasonic frequencies that pest repellers emit are outside of their range of hearing, meaning that there is no risk of discomfort to the ears from these devices.

It’s important to take into account potential behavioural changes and indirect physiological effects, which are subjects of ongoing research in the fields of ornithology and pest management, so this does not completely rule out the possibility of any impacts on birds.

Always check that the device

Prior to plugging any device into an outlet in your aviary or bird room, make sure it is intended for use with birds. When it comes to controlling rodents and other larger pests, ultrasonic repellers are a well-liked and efficient method of pest control. However, they shouldn’t be utilized in the same manner as electronic or ultrasonic pest control devices intended for birds.

Make sure the repellent has been made for indoor use if you intend to use it indoors. Keep an eye out for gadgets that have the word “indoor” printed on them, and review the specifications to determine whether they are suitable for use in an aviary or bird room. You can get more details about the best devices for your specific needs from the manufacturer.

Furthermore, confirm that the ultrasonic repeller has been tested on the animals it will affect, including your birds, and that it won’t upset any of them before buying one. Certain gadgets are made to work with other animals as well, like dogs and cats.

Birds are very sensitive

Birds are very sensitive creatures and can get stressed easily. When rodents and other pests hear these frequencies, ultrasonic repellers, which operate in the high frequency range of 18–23 kHz, emit ultrasonic sounds that drive them away. It is crucial to make sure that the devices you use do not operate at more extreme frequencies (such as 14–18 kHz), as this can permanently harm birds’ hearing.


Are ultrasonic pest repellers safe around birds?

Generally, electronic pest control is safe for pet birds as long as the device is installed properly and kept away from the bird’s living area. If you have an electronic pest control device, it’s a good idea to keep it out of reach of your pet birds.

Are birds sensitive to ultrasonic sound?

Avian hearing is most sensitive to sounds from about 1 to 4 kHz, although they can hear higher and lower frequencies. No species of bird has shown sensitivity to ultrasonic frequencies (>20 kHz).

Do sound deterrents work for birds?

Audio and visual deterrents can be effective in the short-term, but birds can get used to them. Chemical deterrents can be effective, but their effectiveness may vary, they may cause cascading harm in your environment, and birds can be immune or develop immunity to the effects of this type of treatment.

Do sonic cat repellers affect birds?

The device does not affect birds, so if you also want to keep your bird feeding station free from feline predators then this is perfect for you too!
