I’ve had enough of unseen pests, chewed wires, mysterious droppings, and worst of all, the feeling that something is scuttling just out of sight. That’s how I ended up plugging in the Freeze2Trin Pest Defence Ultrasonic Repeller (also sold under names like “Bye Critter” on Amazon). It claims to repel rodents and insects using ultrasonic soundwaves, chemical-free and kid‑safe. But does it work… or is it just LED smoke and mirrors?
What Is the Freeze2Trin Pest Repeller?
According to the brand, the Freeze2Trin Pest Defence Ultrasonic Plug‑In emits high-frequency sound waves, reportedly 20–70 kHz, and electromagnetic pulses designed to disrupt pests’ sensory systems. It markets itself as eco‑friendly, safe for pets and humans, and effective across up to 800–1,600 sq ft per unit. Just plug it in and let the ultrasonic vibes do the rest.
Why I Tried It
I didn’t want sticky traps or chemical sprays, and professional exterminators weren’t an option. The idea of a set‑and‑forget device that claims to deter mice, roaches, ants, and more sounded ideal, plus it was under $25 per plug-in. Again and again, reviews touted the simplicity: plug in, wait a week, and let pests vanish.
My Experience Using It
Plugging it in was easy; I placed one in the kitchen and another in the garage. The first few days showed… nothing. No fewer droppings, no shift in activity. A week in, the LED glowed blue, like it was “working,” but the pests seemed unbothered. Over two weeks, I still found evidence of insects and rodent activity near the devices.
I even rearranged placement and rotated rooms, but nada. If anything changed, it was only that my cat acted oddly near the device (possibly annoyed by inaudible frequencies). Cleaning it didn’t improve anything. It operated continuously but clearly didn’t spook a single pest away.
Pros
- Easy setup, just plug it into any outlet
- No mess, no chemicals, child- and pet-safe design according to brand
- Budget-friendly (usually under $25 per unit)
Cons
- No visible pest reduction in my test case
- Claims of broad coverage (800–1,600 sq ft) are highly questionable
- Some pets may hear or be irritated by the frequencies
- No data or certifications to support ultrasonic efficacy
What Reddit Says
“They are a scam. Save your $.” — r/pestcontrol, endorsing widespread skepticism about plug-in ultrasonic devices
“…the pest control industry would be using them.” — Reddit consensus that if they really worked, professionals would adopt them
Is It a Scam?
Yes, in the sense that it does nothing meaningful. The device exists, the ultrasonic disc lights up, and it consumes a bit of electricity, but there’s no evidence that it deters pests. Experts and redditors repeatedly call these “gimmicks” or outright scams, noting the pests often continue nesting within inches of the devices.
Where to Buy & Price Point
- Available on Amazon and eBay, typically under $25 USD per unit
- Often sold in multipacks, marketed as chemical-free replacements for traps or sprays
Alternatives That Actually Work
- Traditional snap traps or glue boards for targeted rodent control
- Proper exclusion methods: sealing cracks, steel wool in holes
- Peppermint oil bait stations
- Hiring licensed pest control professionals for persistent infestations
Conclusion: Would I Recommend It?
No, absolutely not. The Freeze2Trin plug-in pest repeller is a flashy gadget that sprays LED and emits ultrasonic tones, but it doesn’t repel pests in any meaningful or consistent way. My pests ignored it entirely. Community feedback overwhelmingly indicates the same. If you’re serious about pest control, spend that $25 on an effective trap or fix entry points instead.
