If you own chickens, you probably take great care in ensuring their environment is safe and comfortable.

One common worry for many poultry enthusiasts is the presence of rodents.

Rodents can bring disease, consume feed, and create a general nuisance in your chicken coop.

Ultrasonic rodent repellents are often touted as an effective, humane way to keep these pests at bay.

However, if you are considering using one, the big question that may be lingering on your mind is: Will an ultrasonic rodent repeller affect my chickens?

Let’s dive into this topic and explore all the key points you need to know.

What is an Ultrasonic Rodent Repeller?

Ultrasonic rodent repellers are electronic devices that emit high-frequency sound waves. These sounds are typically inaudible to humans but can be quite disturbing to rodents.

Here’s a quick breakdown of how they work:

Electronic Emission: The devices emit sound waves at frequencies between 20 kHz and 65 kHz.

Rodent Disturbance: These frequencies are aggravating for rodents, causing them discomfort and discouraging them from settling in the area.

Non-lethal: Unlike traps and poisons, these devices are designed to repel rather than kill rodents, making them a more humane pest control option.

Can Chickens Hear Ultrasonic Sound?

Before delving into any potential effects, it’s essential to understand whether chickens can even hear ultrasonic sounds.

Sound Range of Chickens

Chickens have a hearing range that is quite similar to humans but not identical. They can hear sounds within the frequency range of approximately 125 Hz to 2 kHz. Here’s how this compares:

Chickens: 125 Hz – 2 kHz
Humans: 20 Hz – 20 kHz
Rodents: Up to 90 kHz

Given this comparison, it’s clear that chickens (like humans) cannot hear ultrasonic sounds above 20 kHz. As ultrasonic rodent repellers operate at frequencies between 20 kHz and 65 kHz, these sounds will be inaudible to chickens.

Effects on Chicken Behavior and Health


Although chickens can’t hear ultrasonic sounds, it’s essential to consider other behavioral impacts that may indirectly affect them. For example:

Stress Levels: While the ultrasonic sound won’t stress them directly, additional distress could occur if rodents are driven into the coop temporarily.

Pest Movement: Rodents might not leave the area instantly and may become more active as they are irritated by the repellent.


There is currently no scientific evidence to suggest that ultrasonic rodent repellents cause health issues in chickens.

However, always monitor for:

Sleep Disruption: Ensure that the device’s placement doesn’t disrupt your flock’s sleep cycle due to increased rodent activity.

General Wellness: Keep an eye on their overall health, as increased stress can sometimes lead to secondary health issues.

Safe Usage Tips

Proper Placement

To ensure the safety and comfort of your chickens, consider these tips:

Location: Place the repeller outside the immediate vicinity of the chicken coop. This will help mitigate any indirect stress caused by increased rodent activity within the coop.

Angle: Position the ultrasonic device to direct sound waves away from the chickens.

Monitoring: Keep a watchful eye on both rodent activity and your chickens’ behavior in the days following the installation.

Holistic Approach

An ultrasonic rodent repeller should be part of a broader pest management strategy:

Secure Feed Storage: Keep chicken feed in rodent-proof containers.

Clean Environment: Regularly clean the coop to remove leftover feed and droppings that may attract rodents.

Physical Barriers: Use chicken wire or other sturdy materials to block potential entry points for rodents.

Regular Maintenance

Don’t forget to maintain your ultrasonic devices:

Check Functionality: Ensure the devices are working correctly and replace them as needed.

Update Technology: Occasionally, new models with improved effectiveness may become available, helping you maintain a rodent-free environment efficiently.


In summary, ultrasonic rodent repellers are generally safe to use around chickens. Chickens can’t hear the ultrasonic frequencies these devices emit, and there is no evidence to suggest any direct harm to their health or behavior.

However, always use these devices as part of a broader pest management strategy and continuously monitor your flock to ensure their well-being.

By following best practices and staying observant, you can successfully manage rodents in your chicken coop without causing undue stress or harm to your beloved birds. Happy chicken keeping!

What should I do if my chickens are affected by the ultrasonic rodent repeller?

If you notice that the ultrasonic rodent repeller is affecting your chickens, turn off the device and remove it from the area near the chickens. Consult with a veterinarian if any symptoms of distress persist.

Can I use other methods to control rodents without affecting my chickens?

Yes, there are alternative methods to control rodents that do not involve ultrasonic sound, such as sealing up entry points, removing food sources, and using traps or bait stations designed for outdoor use and positioned away from the chickens.

Will the ultrasonic repeller affect egg production in my chickens?

Stress can affect egg production in chickens, so if the repeller is causing distress, it could potentially lead to a decrease in egg-laying. Closely observe your flock and their egg production patterns when using the device.

What signs of distress should I look for in my chickens if I’m using an ultrasonic repeller?

Signs of distress in chickens can include changes in vocalization, reduced appetite, less social interaction, agitated behavior, or a decrease in egg production. Pay attention to any of these changes after installing an ultrasonic repeller.

Can ultrasonic repellers harm any animals on my farm?

The impact of ultrasonic repellers on animals can vary. While they’re generally considered safe for many domestic animals, some pets, especially those with more sensitive hearing like dogs or cats, could potentially be affected. It’s best to observe your animals for any changes in behavior when the repeller is in use.
