Crittex emits an irregular ultrasonic pulse mice can't tune out — outside the range you, your dog, or your cat will ever hear. Plug it in once. Walk away.
USB-C rechargeable. A full charge runs 28 days. Set it where you actually need it — no outlet roulette.
Operates at 22–55 kHz. You won't hear it. Your dog and cat won't either. Only the mice.
Nothing to spray. Nothing to inhale. Nothing the dog can lick off the floor.
One Crittex covers an open kitchen, a small basement, a one-car garage. Pair two for the whole floor.
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.
Plug the USB-C cable into the back. Wall, laptop, power bank — anything works. A full charge takes ~3 hours and runs 28 days.
Anywhere mice are passing through. Counter corner, pantry shelf, garage floor. No mounting. No cable.
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."
"Two units in the garage. Mice were everywhere — now there's nothing. No droppings, no chewed wires for six weeks. Worth every dollar."
"My wife has two indoor cats and was nervous about ultrasonic. Cats genuinely could not care less. Mice gone in about 11 days."

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.
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.
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.
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.
