Why Wallhush
You don’t want a dead mouse. You want the mice out.
Nothing snaps, nothing to empty or reset. Plug it in and leave it on.
No rodenticide in cabinets where kids open doors and dogs eat anything.
It doesn’t kill anything, so there’s no dead mouse behind the stove.
Walls block ultrasound, so you put one unit in each room you hear them in.
How it works
Wallhush doesn’t catch anything. It fills the room you protect with a shifting high-frequency sound that makes it uncomfortable for mice.
USB-C cable into the unit, the 5 V adapter into the wall. Set it 10–50 inches off the floor, front facing into the room, nothing in front of it.
It sweeps across 25–65 kHz, so it never settles on one steady tone. Pick the mode that fits the room. One mode runs at a time.
Mice prefer quiet, sheltered spots. Keep the unit running, close the way back in, and the protected room stops being one of them.

Inside Wallhush One
Ultrasonic, pressure wave and EM. One at a time, picked with one button.
The frequency keeps moving, second to second, instead of one steady tone.
The round LCD shows the mode and that the unit is running.
Cable and wall adapter in the box. No battery, nothing to recharge.
About $4–8 a year to run all day, every day.
An LED strobe you can switch off for rooms you use at night.
Pets, honestly
25–65 kHz overlaps what dogs and cats can hear. Watch how yours react, and move or switch off the unit if they seem bothered. Keep it out of rooms with pet hamsters, guinea pigs, rabbits, pet rats, pet mice or gerbils.
The smart swap
Traps and bait deal with a mouse after it’s in. Then someone has to empty the trap, or find the one that died in the wall.
| Question |  | Snap traps | Poison bait | Glue traps |
|---|---|---|---|---|
| What it does | Makes the protected room uncomfortable for mice | Kills one mouse at a time | Kills mice that eat it | Holds a mouse stuck in place |
| Cleanup | Nothing to clean up | A dead mouse in the trap | Mice can die inside walls | A live, stuck mouse to deal with |
| Chemicals | None | None | Rodenticide in your home | None |
| Kids & pets | No contact. Some pets can hear it. | Can catch fingers and paws | Kids and pets can eat it | Fur and paws can get stuck |
| Upkeep | Plug in, leave it on | Bait, check, reset | Refill bait stations | Check and replace |
We compare Wallhush with traps and poison bait only, not with other ultrasonic repellers.

FAQ
One per enclosed room where you’ve seen, heard or smelled signs. Ultrasound doesn’t pass through walls, floors or closed doors, so a unit in the kitchen does nothing for the attic. Pick 1, 3 or 6, or set any number from 1 to 50.
Yes. The price per unit drops as you add units: $59.99 for one, $49.99 each for two, $44.99 each for 3–5, $39.99 each for 6–9 and $34.99 each for 10 or more. The bundles and the + and − buttons use the same prices.
4,000 sq ft is the maker’s rating for open space. Homes aren’t open space. Walls and furniture block and absorb ultrasound, so we’d rather you cover each room than rely on one unit.
They can, especially if there’s an easy way in. That’s why we ask you to seal entry points and keep each unit running. Still seeing fresh droppings after that? Call a licensed pest professional, and use our 30-day returns if Wallhush isn’t for you.
We don’t promise a timeline. Every home is different. Seal the gaps, keep each unit running, and use our 30-day returns if it’s not for you.
No. The video at the top is a dramatization of how Wallhush is meant to be used, made for this page. It is not a recording of a real home or proof of results.
Possibly. The maker describes ultrasonic and pressure wave as a “small sound”: quiet, but some people, especially kids and teens, can hear them. EM mode makes a sharp sound on purpose, so use it only when nobody’s in the room.
No. Wallhush is a plug-in device. It runs on the included 5 V USB adapter through the USB-C port and has no battery.
No. Wallhush runs on a 5 V USB adapter. It isn’t connected to your home’s wiring and doesn’t send anything through it.
Keep it out of rooms with pet hamsters, guinea pigs, rabbits, pet rats, mice or gerbils. Dogs and cats may hear it. Watch how yours react and move or switch off the unit if they seem bothered.
At 3–5 W, one unit running all year uses about 26–44 kWh. At $0.17 per kWh that’s roughly $4–$8 a year.
