Worth every dollar

"I lived with the scratching in the kitchen wall for a month. Plugged Crittex in on a Sunday. By next Saturday I couldn't hear them anymore. My cat sleeps within two feet of it."

Two units in the garage — done

"Mice were tearing through stored cardboard for years. Put two of these on opposite corners and the activity dropped to nothing in about two weeks. No droppings, no chewed wires. Going on six weeks now."

Cats don't care at all

"Wife was anxious about the ultrasonic part. We have two indoor cats. Genuinely zero behavior change. Mice in the pantry were gone in about 11 days."

First thing in a decade that actually worked

"I've tried every plug-in, peppermint trick, snap trap, glue board, professional service. Crittex is the first thing that just made the problem stop without leaving me bodies to dispose of."

Quick answers.

How many do I need?

One Crittex covers up to 1,200 sq ft in an open, unobstructed space. Walls and closed doors block ultrasound, so plan one per room you want covered. Most single-floor homes do well with 2–3 units; the 4-pack is the typical full-home setup.

How long until mice leave?

Median time to "pest-gone" in our internal testing is day 9; 94% of households are mouse-free by day 14. Heavy infestations can take up to 21 days.

Is it safe for cats and dogs?

Yes. Crittex operates between 22 and 55 kHz with an irregular pulse pattern. Dogs and cats are unbothered. We do not recommend running it in a room shared with rabbits, hamsters, or pet reptiles.

Will it interfere with electronics?

No. Crittex emits acoustic ultrasound, not radio frequency. It will not affect Wi-Fi, baby monitors, hearing aids, or pacemakers.

What if it doesn't work?

30-day money-back guarantee. Email support@crittex-official.com and we'll refund you. No interrogation.
