Haycone Ultrasonic Pest Repeller Review: Does It Actually Work?
If you’ve ever dealt with mice, roaches, or spiders crawling around your home, you know how frustrating pest control can be. Traps are messy, chemical sprays are toxic, and calling an exterminator isn’t cheap. So when a simple plug-in device promises to drive pests out of your home using nothing but sound waves, it’s hard not to be tempted.
That’s exactly what the Haycone High Power Frequency Ultrasonic Pest Repeller claims to do. At $29.99 for a 6-pack, it markets itself as a safe, chemical-free, and hassle-free solution for keeping your home pest-free.
But does it actually deliver on that promise?
We put the Haycone through a live test with real mice to find out — the same way we’ve conducted a comparison test on other ultrasonic repellers on the market. No staged results, no guesswork, just a straightforward test to see whether this device does what it claims. Here’s everything you need to know before you buy.
⭐ Quick Verdict
The Haycone Ultrasonic Pest Repeller sounds like the perfect solution. No chemicals, no mess, and safe for everyone at home. But after putting it through a live test with real mice, the results were eye-opening. Read on to find out what actually happened.

How We Tested It
Phase 1: No Bait Test
Testing Setup: The ultrasonic repeller was placed directly inside a enclosed bucket along with the mice, giving us a controlled, close-range environment to observe their natural reactions.
What We Monitored: We tracked the mice carefully throughout the session, watching for any behavioral cues that the device was having an effect specifically:
Whether they instinctively steered clear of the device or kept their distance
Any unusual restlessness, agitation, or signs of distress
Attempts to climb out or escape the space
Visible fear or hesitation when near the unit
Phase 2: Bait Test
Food Bait Test: To make things more challenging, we scattered sunflower seeds directly on top of and around the ultrasonic repeller.
What This Tested: It’s straightforward — a device that truly repels rodents shouldn’t lose that power just because there’s food nearby. If it works, hunger shouldn’t be enough to override it.
Expected Result: Any ultrasonic device worth trusting would create a strong enough deterrent that the mice stay away from the food entirely — no hesitation, no nibbling, no exceptions.
Performance Test Results
No Bait Test
No Bait Test: When the Haycone Ultrasonic Pest Repeller was switched on inside the testing area, the expectation was clear — the mice should show some sign of discomfort, avoidance, or distress. Instead, the opposite happened.
Observation: Both mice roamed freely around the bucket as if the device wasn’t even on. At no point did they flinch, freeze, or attempt to move away from it. What was most surprising was that one of them actually moved toward the device and began trying to climb up to reach it despite the unit actively emitting its ultrasonic frequency.
Bottom Line: The No Bait Test produced zero evidence that the Haycone High Power Frequency has any meaningful effect on rodents. No fear response, no avoidance, no distress — just two mice going about their business as if the device didn’t exist.
Bait Test
Bait Test: With the Haycone rodent repeller still running, sunflower seeds were placed directly on and around the device. If the repeller genuinely works, no amount of food should be tempting enough to bring the mice anywhere near it.
Observation: The mice didn’t hesitate for a second. They ate the bait without any concern, then moved straight toward the seeds placed around the device. The most telling moment came when one mouse walked directly underneath the running unit and ate the bait placed right below it — completely unbothered by the ultrasonic frequency emitting just inches above its head.
Bottom Line: If the No Bait Test left any room for doubt, the Bait Test removed it entirely. The Haycone Ultrasonic pest repeller couldn’t even use food as a barrier between the mice and the device. If it can’t keep mice away from food sitting right on top of it, it simply doesn’t work.

The Haycone High Power Frequency Ultrasonic Pest Repeller holds a strong middle ground in this comparison — offering more features than basic single-frequency devices while remaining straightforward and easy to use. Here’s how it compares:
vs OWLTRA OW-5 Ultrasonic Rodent Repeller
The OWLTRA OW-5 is the most basic option of the five, operating on a single fixed frequency with no switching capability — meaning rodents can adapt to it over time. The Haycone’s variable 20–60 kHz range and 3 working modes already put it a step ahead. It also covers up to 1,000 sq ft compared to the OW-5’s medium room coverage, and comes in a 6-pack versus the OW-5’s 4-pack. Read our full OWLTRA OW-5 ultrasonic rodent repeller review to see how it performed in our live test.
vs PIMAG Electronic Pest Repeller
The PIMAG Electronic edges ahead of the Haycone in coverage area at up to 1,600 sq ft and offers a wider frequency range of 10–65 kHz. However, both devices share similar core features — frequency switching, multiple modes, and a 6-pack quantity — making them closely matched overall. The Haycone remains the simpler and more straightforward option of the two. See our full PIMAG Electronic review for a detailed breakdown.
vs Xmuniha Ultrasonic Rodent Repeller
The Xmuniha Ultrasonic is the most feature-packed option in this comparison, with 3 PIR infrared motion sensors, 9 LED strobe lights, and 360° coverage — features the Haycone doesn’t have. However, the Xmuniha is sold individually while the Haycone comes in a 6-pack, making the Haycone a significantly better value if you need to cover multiple rooms at once. Check out our full Xmuniha Ultrasonic review to see if the extra features are worth it.
vs Borhood Ultrasonic Rodent Deterrent
The Borhood Ultrasonic leads the group in raw coverage at up to 3,900 sq ft and is the only device here that can be used both indoors and outdoors. It also offers 4 working modes and 360° coverage. That said, it’s sold individually and draws 3–5W of power — the same as the Haycone — so for indoor multi-room protection, the Haycone’s 6-pack still offers better overall value. Read our full Borhood Ultrasonic review for the complete picture.
Who Should Buy the Haycone Ultrasonic Pest Repeller?
Who It Might Still Work For:
People who want a completely chemical-free and poison-free layer of pest prevention in their home
Households with children or pets that need a non-toxic pest control option
Those dealing with a very light or early-stage pest situation where prevention is the goal
Homeowners who want a low-maintenance, plug-and-forget solution alongside other pest control methods
Anyone looking for a humane way to repel pests without killing them
Who Should Definitely Skip It:
Anyone dealing with an active or severe infestation that needs immediate results
People looking for a standalone solution that works on its own
Households with pet rodents like hamsters, guinea pigs, or gerbils as the ultrasonic frequency will affect them too
Anyone who can’t afford to wait 2–4 weeks for results that may never come
Those who need outdoor pest control coverage as the device is strictly for indoor use only
Frequently Asked Questions
1. Does the Haycone High Power Frequency Ultrasonic Pest Repeller actually work?
Results vary depending on the severity of your pest situation. The Haycone High Frequency Ultrasonic Pest Repeller uses a variable 20–60 kHz frequency range that automatically switches to prevent pests from adapting, which gives it an advantage over single-frequency devices. However, for active or severe infestations, it works best when used alongside traps and baits rather than as a standalone solution.
2. How long does it take for the Haycone to show results?
Expect to see a noticeable reduction in pest activity within 1–2 weeks of continuous use. For more established infestations, it may take up to 3–4 weeks before significant results appear. The key is to keep the device plugged in and running without interruption.
3. Is the Haycone safe to use around children and pets?
Yes. The Haycone is completely non-toxic and chemical-free, making it safe for children and non-rodent pets like cats and dogs. However, it should not be used in homes with pet hamsters, guinea pigs, gerbils, or other pet rodents as the ultrasonic frequency will affect them too.
4. How many units do I need for my home?
The Haycone covers up to 1,000 sq ft per unit. Since ultrasonic sound waves cannot penetrate walls, it is recommended to place one unit per room where pest activity has been spotted. The 6-pack makes it convenient to cover multiple rooms at once.
5. What pests does the Haycone repel?
The Haycone targets a wide range of common household pests including mice, bed bugs, roaches, ants, mosquitoes, and spiders. Its 3 working modes allow you to switch between settings depending on the type of pest you are dealing with.
6. Where is the best place to put the Haycone?
Place the device in an open area free from obstructions like furniture, curtains, or walls that could block the sound waves. A central location in each room works best. Avoid placing it inside cabinets or behind large objects as this significantly reduces its effective range.
Final Verdict: Is the Haycone Ultrasonic Pest Repeller Worth It?
At $29.99 for a 6-pack, the Haycone looks like a solid deal on paper — variable frequency switching, 3 working modes, and a safe chemical-free design. But our live test told a different story. The mice showed zero fear, ignored the running device entirely, and ate bait placed right next to it without hesitation.
Is it worth buying? As a standalone solution for an active infestation — no. But as a supplementary, hands-off layer alongside traps and baits, it offers reasonable value for the price. Just go in with the right expectations and it won’t disappoint.
