"reduced the activity but didnt eliminate it completely. my 1920s farmhouse has more gap and crack access points than i realized going in. customer support was actually great - immediate on the refund, no hassle whatsoever. i think this works, just not as a standalone solution when youve got real structural issues like i do."

HelloPest response

Patricia is right, and we should have caught this earlier. AntRx repels. It cannot block a structural gap that gives ants direct entry. For older homes with foundation cracks or deteriorated weatherstripping, sealing entry points first is necessary. Patricia shipped the units back and we refunded her right away. If she ever seals those gaps, we'll make it right at no charge. - Marcus, HelloPest

"bought ONE unit for a 2400 sq ft two story house. didnt work. contacted support and they explained i needed AT MINIMUM 3 units for that square footage - thats on the product page but i totally missed it. they sent me a 2-pack at no extra charge to complete coverage. after that it worked exactly as described. my mistake honestly"

HelloPest response

This one's on us. The coverage calculator is there to prevent exactly this situation, and we should do a better job surfacing it. Brian's right that one unit can't cover a full two-story home - ultrasonic frequencies don't pass through floors or walls. We made it right with a free 2-pack. Leaving this review up because undercovering is the #1 reason AntRx underperforms. - HelloPest Support

Why acting now matters

One scout becomes hundreds.

A single ant in your kitchen isn't random. It's a scout reporting back that the food is reachable. Once that signal goes home, the colony sends foragers along the same path. Every hour you wait is another wave memorizing your pantry.

  • They contaminate every surface they cross Ants walk across your counters after walking across whatever's outside: soil, trash, pet waste, dead insects. Even one forager leaves a trail of bacteria across every food-prep surface it touches.
  • Exterminator contracts compound quickly A single spring treatment runs $150–$300. Most ant contracts require quarterly retreatment at $50–$100/visit. That's $350–$700/year, indefinitely, plus chemical residue along every baseboard.
The math that changes the decision

What one scout ant becomes

4 hrs
From one scout to a full trail A scout finds crumbs in your pantry. Within 4 hours it has called in dozens of foragers to follow the same path. By morning, hundreds.
500
Eggs per day from a single queen A backyard odorous-ant colony houses 10,000–100,000 workers. Every one of them can follow a trail into your kitchen. The queen adds another 500 every day you wait.
$399+
Average first exterminator visit Plus quarterly retreatment. Most contracts are 12-month minimum: $600–$1,200/year for chemical perimeter spraying along every surface your kids touch.
The technology

Drives ants out.
Keeps new ones out.

AntRx works at both ends. Existing ants start leaving. New scouts find easier food outside, so the colony never gets recruited to your home.

AntRx technology diagram showing multi-surface ultrasonic vibration driving a cluster of ants away from the device
Technology 01
Drives Existing Ants Out

Foragers already inside detect AntRx's ultrasonic waves through their antennae. Every surface in the home feels unsafe to them. Ants start leaving right away. The number you see drops quickly. No bait. No spray. No bodies to clean up.

Technology 02
Prevents New Ants From Returning

The same 25,000–65,000 Hz ultrasonic field also stops new ants from coming in. Ants are foraging optimizers. They pick the easiest food. AntRx tilts that math against your home. Scouts don't enter, don't lay a pheromone trail, and the colony never gets recruited back in.

Technology 03
Adaptive Pattern Sweep

Ants habituate to constant signals. Within 2–4 weeks they tune out a fixed-frequency device the way you tune out a refrigerator hum. AntRx continuously varies its pattern so the signal never becomes background noise. Above the hearing range of humans, dogs, and cats, so your pets don't hear it, aren't annoyed by it, aren't harmed by it. That's why $20 devices fail in a month and AntRx lasts years.

01
Plug into any standard outlet

Works in any 120V outlet.

02
Deterrence starts tonight

All three layers begin on power-up. You won't hear anything. The frequencies are above human and pet hearing.

03
Ants get uncomfortable. They start leaving.

The home becomes uncomfortable for foraging ants. They look for relief and begin exiting. New scouts redirect to easier food outside instead of laying a trail to your pantry.

Quick answers before you scroll further
Does it work through walls?
The ultrasonic vibration conducts through drywall, studs, and baseboards. The same surfaces ants use to feel their way. The vibration field covers about 800 sq ft per unit. For whole-home coverage, one unit per floor.
How long until the ants are gone?
Most homes see the visible ant line thin within hours and clear within 24–48. Full colony displacement (scouts stop returning entirely) takes 5–10 days. Not working by day 30? Ship it back for a full refund.
Is it safe for my dog or cat?
Yes. AntRx operates above the hearing range of dogs and cats. No chemicals. No residue. No contact risk. One exception: keep at least 3 feet from hamster, gerbil, or fish habitats.
What if it doesn't work for me?
Full refund within 30 days. Ship it back, we refund you. No questions asked. Just reply to your order confirmation email to start the process.
Safe by design

Works on ants.
Not on anything else.

The frequencies AntRx uses are inaudible to humans, dogs, cats, birds, and fish. They do not affect electronics, WiFi, or medical devices.

Children

Ultrasonic frequencies are inaudible to humans of all ages. No residue. No contact risk. Safe to use anywhere in the home.

Dogs & Cats

Dogs and cats cannot detect AntRx's operating frequency range. Verified safe for household pets including dogs, cats, and birds.

Fish & Small Pets

Fish, hamsters, gerbils, and other small caged pets may be sensitive to ultrasonic frequencies. Do not place AntRx in the same room as their habitat.

Electronics & WiFi

Operates on frequencies entirely separate from WiFi, Bluetooth, baby monitors, and other home electronics. Zero interference.

Why it doesn't bother your household: the hearing ranges
Human hearing
up to 20 kHz
✓ Safe
Dogs & cats

Target
↑ Human and pet hearing ends below 25 kHz · AntRx operates entirely above this point

AntRx operates at 25–65 kHz, entirely above the hearing range of humans, dogs, and cats. Your household hears nothing. Ants are highly sensitive to vibration in this range - they detect it through mechanoreceptors in their legs and antennae and retreat from the surfaces transmitting it.

Spring is when colonies wake up.

When soil temperatures cross 50°F in late March, outdoor colonies wake up and start sending foragers indoors. Plug AntRx in before the spring wave - every new scout meets the vibration field at your baseboards before recruiting more workers.

Questions & answers

Everything you want to know before you buy.

I bought a cheap ultrasonic device before, and it stopped working after a week. Why is this different?

This is the most common objection we hear, and it's a completely fair one. Every $15–30 ultrasonic device on Amazon emits a fixed frequency. Ants are adaptive. Within a week they habituate to a constant signal and stop responding. It becomes background noise, like a refrigerator hum. AntRx uses an adaptive pattern sweep that continuously randomizes its frequency pattern, so there's no single frequency for them to acclimate to. If you gave up on ultrasonic before, you gave up on fixed-frequency. Not on the technology itself.

How many units do I need for my home?

It depends on your home's layout. Square footage matters less than where the entry points and food zones sit relative to each other. A multi-story SFH with a garage and finished basement needs different coverage than a 1-bedroom apartment, and a townhouse with shared walls needs different coverage than either. Take the 2-minute coverage quiz for a count built around your specific home.

Will ants get used to it over time?

No. This is the key failure mode of cheap ultrasonic devices. AntRx uses an adaptive pattern sweep that continuously randomizes its frequency pattern - preventing acclimation. Fixed-frequency devices become background noise. AntRx doesn't.

Will it interfere with my WiFi, pacemaker, or other devices?

No. AntRx operates on ultrasonic and low-level electromagnetic frequencies completely separate from WiFi, Bluetooth, or medical devices. It plugs into a standard 120V outlet and runs passively. No RF interference of any kind.

Do I need to keep it plugged in permanently?

Yes, for ongoing protection. Once the current population disperses, new ants can enter the home. Keeping AntRx plugged in year-round creates a continuous barrier. Because there's no maintenance required, this is set-and-forget.

Does it kill ants, or just repel them?

Deters and prevents. Ants are foraging optimizers. They go where the food is easiest to reach. AntRx makes your home the difficult choice. Foragers already inside: the ultrasonic waves create a field uncomfortable enough that ants retreat and redirect to easier food outside. New scouts: the same field feels hostile before a scout commits to foraging in your home. The scout never deposits the pheromone trail that would have recruited the rest of the colony. No chemical signal back to the queen, no foraging route mapped, no colony recruitment. Killing one visible ant doesn't solve the problem when the colony keeps sending more. Making your home a place ants don't choose to forage in does, and it does so without leaving a pile of dead ants to clean up or bait residue for your kids to touch.

Will AntRx work on an active carpenter ant infestation?

No. If you've already got an active carpenter ant colony established in your structure (frass piles, hollow-sounding wood, indoor swarmers in winter, rustling in walls), that's a structural problem and you need a licensed pest professional to locate and treat the nest. AntRx is for prevention. It deters scout ants from entering your home and laying the pheromone trails that recruit a colony in the first place. Once a colony is already inside the framing, the field at your baseboards is downstream of the problem.

Does it work on other pests besides ants?

AntRx is optimized for ants. Customers also report meaningful reduction in cockroaches, spiders, mice, and stink bugs as a secondary effect, since each of those species is also sensitive to substrate vibration in this frequency range (or, in mice, hears it natively). AntRx is not a mosquito or fly repellent. Those species fly and don't rely on the same surface-vibration cues.

Can I use it outdoors or in my garage?

Garages, unfinished basements, and attics with a standard 120V outlet: yes, and this is often where the problem starts (ants enter through garage door seals and crawl-space gaps). Outdoors: AntRx is not weather-rated for direct rain exposure. Covered porches, screened enclosures, and weatherproof shed outlets work. For outdoor foundation protection, placing a unit along the nearest interior wall still disrupts trails on the adjacent exterior surface.

What if I have a severe infestation? Visible colony, thousands of foragers?

We'd rather give you an honest answer than oversell. AntRx works best as continuous ant deterrence for moderate infestations. For severe situations - a visible carpenter ant colony in wall framing, a fire ant mound outside a foundation, or thousands of workers streaming in from one entry point - AntRx alone isn't the full solution. In those cases, seal the entry point first, address any moisture source for carpenter ants, then deploy AntRx as continuous prevention. Use the 30-day guarantee window to confirm it's working. If it doesn't, we'll refund you.

Beyond ants

Built for ants. Works on more.

AntRx is tuned for ants, but the ultrasonic frequency range disrupts mechanoreceptors that several common household pests rely on. Plug it in for ants and you'll see secondary effects on the rest sharing the same coverage area. One device. No extra purchase.

Primary
Ants

Foragers redirect to easier food outside within 24–48 hours. New scouts don't lay a pheromone trail to your pantry to begin with. The kitchen never gets recruited as a foraging zone.

Cockroaches

Sense substrate vibration through cercal receptors at the rear of their abdomen. The signal reads like predator activity and pushes them out of harborage zones.

Spiders

Detect vibration through slit sensilla on their legs, the same sense they use to find prey. Interferes with prey-detection and disrupts web-building.

Mice

Hear ultrasonic natively up to ~85 kHz. The 25-65 kHz operating range falls in their stress-response band; rodents avoid rooms with sustained activity.

Stink bugs

Reduced indoor overwintering pressure during fall and spring emergence. Customers report fewer wall-cavity invaders in deployed spaces.

One device. Same plug, same 30-day money-back guarantee. No second purchase to cover the rest of the house.
