If you’ve ever dealt with rats or mice in your house, you’ve probably seen ultrasonic pest repellents all over Amazon. The marketing makes it look like rodents instantly panic and flee the second you plug one in. So naturally, I had to test them for myself.
I picked up 5 of the best-selling ultrasonic rodent repellents on Amazon and put them through two real-world tests using actual mice. First, I wanted to see how the mice reacted to the sound alone. Then I introduced bait to see if the repellents could actually stop them from approaching food.
If you’d like to watch the video of me testing these repellents, watch here:
How I Tested These Ultrasonic Rodent Repellents
To keep the testing fair, every product went through the same two rounds:
Round 1 — No Bait Test
The ultrasonic device was placed inside the testing bucket with the mice. I watched for:
- Avoidance behavior
- Running away
- Stress reactions
- Attempts to escape
- Any noticeable fear of the device
Round 2 — Bait Test
I introduced sunflower seeds near or directly on the device to see if the mice would avoid the food due to the ultrasonic sound.
If these products actually worked, the mice should’ve stayed far away from the bait.
The Ultrasonic Repellents I Tested
The first product tested was the OWLTRA Ultrasonic Rodent Repeller, priced at $24.69 on Amazon at the time of filming. According to the product listing, it emits high-frequency sound designed to force rodents to flee.
Instead… the mice literally ran toward it.
One mouse even started climbing up toward the device trying to reach it. I had to lift the cord because it kept attempting to interact with it. Definitely not the reaction you’d expect from something claiming to repel rodents.
OWLTRA Results
- No visible fear response
- Mice approached the device immediately
- Attempted climbing behavior
- Failed the bait test
Next was the Haycone High Power Frequency Pest Repeller for $29.99. This one claims to repel mice, spiders, roaches, and bed bugs all at once.
The mice completely ignored it.
They casually walked around the bucket like nothing was happening. At one point they even tried climbing toward the device. Ironically, the loud buzzing noise annoyed me more than it bothered the mice.
Haycone Results
- No avoidance behavior
- Mice stayed near the device
- Loud audible sound
- Failed the bait test
The PIMAG Electronic Pest Repeller also came in at $29.99.
This one actually gave me hope for a second.
As soon as I plugged it in, one of the mice jumped twice trying to get out. But after those initial reactions, both mice settled down and started behaving normally again. Shortly after, they were sitting right next to the device.
PIMAG Results
- Brief initial reaction
- No long-term avoidance
- Mice stayed near the repeller
- Failed the bait test
The Xmuniha Ultrasonic Rodent Repeller was one of the more unique devices because it included LED strobe lights in addition to ultrasonic sound. Price: $49.99.
The lights didn’t help at all.
The mice immediately walked up to it, sniffed around, and even climbed on top of the device. At one point it honestly looked like they were enjoying it more than avoiding it.
Xmuniha Results
- No fear response
- Mice climbed directly on the device
- LED lights had no noticeable effect
- Failed the bait test
Last up was the Borhood Ultrasonic Rodent Deterrent, the most expensive product tested at $54.99.
Unfortunately, the higher price didn’t translate to better performance.
The mice behaved completely normally throughout the test and spent plenty of time on the same side as the device.
Borhood Results
- No avoidance behavior
- Mice remained comfortable near the device
- Failed the bait test

| Xmuniha | On top of device | Climbed on repeller to eat bait | Failed |
So… Are Ultrasonic Rodent Repellents a Scam?
After testing 5 of Amazon’s best-selling ultrasonic rodent repellents, I honestly saw zero convincing evidence that they worked.
The mice:
- Didn’t avoid the devices
- Didn’t fear the sound
- Didn’t avoid food near them
- Sometimes were literally attracted to the devices
And considering some of these cost over $50, that’s pretty disappointing.
The Product That Actually Worked
After all five ultrasonic devices failed, I tested something completely different: the Mighty Mint Rodent Repellent spray.
This product uses peppermint oil instead of ultrasonic sound and cost only $21.98 — cheaper than every device tested.
The difference was immediate.
As soon as I sprayed one side of the bucket:
- The mice avoided the sprayed area
- One scratched its face and moved away
- Both mice stayed on the non-sprayed side
- They refused to eat bait placed in the sprayed area
It was the only product in the entire video that actually changed the mice’s behavior.
Final Verdict
If you’re thinking about buying an ultrasonic rodent repeller, I’d save your money. Based on my testing, none of these devices did what they claimed to do.
The peppermint spray ended up outperforming every ultrasonic device in this test while also being the cheapest option.
Sometimes the simple solution really is the better one.
