Built like an appliance.
Quiet like one too.

01

Cordless

USB-C rechargeable. A full charge runs 28 days. Set it where you actually need it — no outlet roulette.

02

Silent to humans

Operates at 22–55 kHz. You won't hear it. Your dog and cat won't either. Only the mice.

03

No chemicals

Nothing to spray. Nothing to inhale. Nothing the dog can lick off the floor.

04

1,200 sq ft

One Crittex covers an open kitchen, a small basement, a one-car garage. Pair two for the whole floor.

Same design.
Different purpose.

Each Crittex is factory-tuned to the species it ships for. The hardware is identical — the frequency pattern isn't. Get the one you actually need.

How it works

Charge once.
Walk away.

01

Charge

Plug the USB-C cable into the back. Wall, laptop, power bank — anything works. A full charge takes ~3 hours and runs 28 days.

02

Set it down

Anywhere mice are passing through. Counter corner, pantry shelf, garage floor. No mounting. No cable.

03

Walk away

Press the C. The LED holds green. The room sounds the same to you. To them, it's unlivable. Median time to "pest-gone": 9 days.

"I lived with the scratching for a month. Plugged this in on a Sunday. By the next weekend, dead silent. Cat sleeps right next to it."

Frequently asked.

How long until I notice mice leaving?

Most customers report sharp drops in activity inside the first 7–10 days. Our internal field testing shows median "pest-gone" at day 9 and 94% gone within 14 days. Heavy infestations can take 3–4 weeks.

Is it safe for my dog and cat?

Yes. Crittex emits between 22 and 55 kHz. Dogs hear up to ~45 kHz but the irregular pulse pattern doesn't trigger them. Cats are unbothered. Small mammal pets (rabbits, hamsters) should not share a room with the device.

How many do I need?

One Crittex covers up to 1,200 sq ft of unobstructed space. Walls and closed doors block ultrasound, so plan one per room you want covered. A typical single-floor home: 2–3 units.

Does it really not kill anything?

Correct. Crittex makes the space unlivable to pests — they leave on their own. There's nothing to dispose of, no carcasses, no smell. It's the opposite of a trap.

What if it doesn't work?

30-day money-back guarantee, no questions. Email us, ship it back, get a refund. Most people don't.
