How We Tested It
No Bait Test
Testing Setup: The ultrasonic device was placed inside a bucket together with the mice to observe their reactions up close.
What We Monitored: Throughout the test, we watched closely for any signs that the mice were affected by the device, including:
Whether they actively avoided or moved away from it
Signs of stress or agitation in their behavior
Attempts to escape the bucket
Any visible fear response toward the device
Bait Test
Food Bait Test: To push the test further, I placed sunflower seeds directly on and around the ultrasonic device to see how the mice would respond.
What This Tested: The idea was simple — if the device genuinely repels rodents, the mice should want nothing to do with it, even if food was right there waiting for them.
Expected Result: A truly effective ultrasonic repeller would keep the mice away from the bait entirely, no matter how tempting the food was.
Performance Test Results
No Bait Test
No Bait Test I placed the OWLTRA OW-5 Ultrasonic Rodent Repeller inside the testing area and switched it on. The reaction from the mice was immediate — and not in the way the product claims.
Observation Both mice headed straight toward the device without any hesitation. One of them even started trying to climb up to reach it. To keep things fair and prevent any physical contact with the device, I lifted the cord slightly — but instead of backing away, the mouse just tried even harder to get to it.
Bottom Line There was no fear. No avoidance. No distress. Just two mice that were completely unbothered by a device that’s supposed to make them want to flee.
Bait Test
Bait Test — What Happened With the device still running, I introduced sunflower seeds directly on and around the OWLTRA OW-5. The logic was straightforward — if this device genuinely repels rodents, the mice should want nothing to do with anything near it, food or not.
Observation The mice continued eating the leftover bait from the previous test without any hesitation. Then one of them walked over and ate the bait placed directly underneath the device — completely unbothered by it running just inches above.
What This Proves The OWLTRA OW-5 didn’t just fail to repel the mice — it couldn’t even keep them away from food placed right next to it. For a device that’s supposed to create an unbearable environment for rodents, the mice treated it like it wasn’t even there.
Final Results
🧪 No Bait Test
| What We Expected | What Actually Happened |
|---|---|
| Mice avoid the device | Both mice went straight toward it |
| Signs of fear or stress | Zero hesitation or distress |
| Mice attempt to flee | One mouse tried to climb on it |
| Device creates discomfort | Mouse tried even harder when cord was lifted |
| Result | ❌ Failed |
🧪 Bait Test
| What We Expected | What Actually Happened |
|---|---|
| Mice avoid food near the device | Continued eating bait without hesitation |
| Device creates an unbearable environment | One mouse ate bait directly underneath it |
| Repeller keeps mice away from the area | Mice treated the device like it wasn't there |
| Result | ❌ Failed |
Overall Breakdown
Across both tests, the OWLTRA OW-5 showed zero meaningful effect on the mice:
❌ No Fear Response — The mice showed zero hesitation or distress around the device
❌ No Avoidance — Instead of steering clear, they walked straight up to it
❌ Climbing Behavior — They even attempted to climb on it
❌ Failed Bait Test — Food placed directly on the device was eaten without any hesitation

vs Haycone High Power Frequency Pest Repeller
The Haycone High Power is a noticeable upgrade over the OW-5 in almost every technical category. It operates across a variable 20–60 kHz frequency range instead of a single fixed tone, which makes it significantly harder for rodents to adapt and tune out over time. It also offers 3 working modes so you can target different pest types, and comes in a 6-pack giving you broader home coverage for the price. If the OW-5’s single frequency is its biggest weakness, the Haycone directly solves that problem. Read our full Haycone High Power Frequency Pest Repeller review to see how it performed in our tests.
vs PIMAG Electronic Pest Repeller
The PIMAG Electronic pest repeller pushes the bar further with coverage of up to 1,600 sq ft — making it one of the strongest performers in this category for larger homes. Its 10–65 kHz frequency range is the widest of all five repellers compared here, and its multiple working modes give you more flexibility depending on your pest situation. Like the Haycone, it comes in a 6-pack and supports frequency switching, two features the OW-5 simply doesn’t offer. Check out our full PIMAG Electronic Pest Repeller review to see if it lives up to its specs.
vs Xmuniha Ultrasonic Rodent Repeller
The Xmuniha Ultrasonic is the most feature-rich option in this comparison by a wide margin. It’s the only repeller here equipped with a PIR motion sensor system — 3 infrared sensors that actively detect rodent movement and trigger a response, rather than just passively emitting sound. Add in 360° coverage, 9 LED strobe lights, and 3 working modes including an Auto setting, and you have a device that actually reacts to what’s happening in the room. For anyone who wants a smarter, more responsive solution, the Xmuniha is worth serious consideration. See how it held up in our full Xmuniha Ultrasonic Rodent Repeller review.
vs Borhood Ultrasonic Pest Repeller
The Borhood Ultrasonic is the most versatile and powerful option of the five. It leads the group in raw coverage at up to 3,900 sq ft — more than triple what the OW-5 covers — and pairs that with a 25–65 kHz frequency range, 4 working modes, and 360° sound distribution. What sets it apart further is its ability to be used both indoors and outdoors, making it the only repeller in this comparison that can protect garages, patios, and semi-open spaces. If you need maximum coverage and flexibility, the Borhood is the one to beat. Read our full Borhood Ultrasonic Pest Repeller review to see our complete breakdown.

Frequently Asked Questions
1. Does the OWLTRA OW-5 Ultrasonic Rodent Repeller actually work?
This is the most searched question about the product. Results vary — while the device uses ultrasonic technology designed to disturb rodents’ nervous and auditory systems, real-world tests have shown mixed results. For established infestations, it is necessary to also use baits and traps alongside the device for it to be truly effective.
2. Is the OWLTRA OW-5 safe for pets?
The non-toxic and poison-free design makes it safe to use around children and pets — specifically non-rodent pets like cats and dogs. However, it should not be used in homes with pet mice, hamsters, guinea pigs, or other rodents as the ultrasonic sound will affect them too.
3. How long does it take for the OWLTRA OW-5 to work?
Allow 2 to 4 weeks for ultrasonic sound waves to affect pests with an established food source. For lighter infestations, results may appear sooner — within about two weeks.
4. Where is the best place to put the OWLTRA OW-5?
It’s best to use the repeller in an open space and clear all surroundings before use, since high-frequency sound cannot penetrate walls and solid objects. Place one unit per room where rodent activity has been spotted.
5. Can the OWLTRA OW-5 be used outdoors?
No. The OWLTRA OW-5 is designed for indoor use only and works best in enclosed medium-sized rooms like bedrooms, kitchens, and living rooms.
6. What are the power requirements for the OWLTRA OW-5?
The device runs on 120V AC at 60Hz and draws only 0.35W of power, making it extremely energy efficient for continuous use.
Final Verdict: Is the OWLTRA Rodent Repeller a Good Buy?
The OWLTRA OW-5 looks like a good deal at first. For $24.69, you get a 4-pack that’s safe for kids and pets, easy to use, and completely silent.
But during our live test, it didn’t perform well.
The mice showed almost no reaction to the device. They walked near it, tried to climb on it, and even ate bait placed right on top of it. Based on our testing, the repeller did not do a good job of keeping mice away.
One possible reason is that it uses only one fixed frequency, which rodents may quickly get used to over time.
So, is it worth buying? It may help as an extra tool alongside traps and bait, but we would not recommend relying on it alone for a serious rodent problem. There are other options in the same price range that may work better.
