Why people keep buying it

Quiet. Cordless.
Just works.

01

Silent to humans

15–45 kHz acoustic plus a low-frequency ground-vibration pulse. Silent to humans, dogs and cats. Snakes sense it through their belly scales and avoid the area.

02

Cordless

USB-C in the back. Charge once, runs 28 days. Put it where you actually need it.

03

Pet-safe

Dogs ignore it. Cats ignore it. Birds, beneficial insects, and small mammals pass through unaffected — only ground-dwelling snakes route around it.

04

No clean-up

Nothing to bait. No traps along the fence. No carcasses to bury.

Patio''s a patio again

"Lived with copperheads under the deck every summer. Set two Crittex around the patio in early spring and we haven''t seen one since May. The kids actually play out there now."

Garden shed I can actually go into

"Pulled a black rat snake out of a stored mower last spring and that was it for me. Set Crittex on the shed shelf. Six weeks in and I checked the mower again — nothing."

Worth every dollar twice over

"Acreage backs up to a wash. Used to find tracks across the path daily. Crittex on a stake at each end of the property — tracks dropped to zero in about three weeks."

Beats walking the perimeter

"I used to walk the fence with a shovel every morning before letting the dog out. Now I press a button and walk back inside. Whole property feels different."

Quick answers.

How many do I need?

For outdoor use, plan one Crittex per ~5,000 sq ft of yard. Place units around the perimeter and near sheds, woodpiles, and patios. Most properties use 3–6 units.

How long until snakes leave?

Snakes typically vacate the area within 2–4 weeks. They rely heavily on ground vibration to detect threats, and Crittex''s pulse pattern makes the protected area feel persistently unsafe.

Is it safe for pets and wildlife?

Yes. Dogs and cats are unbothered. Crittex does not harm birds, beneficial insects, or small mammals — it simply makes the area feel less hospitable to ground-dwelling snakes.

Will it work in rain or cold?

Yes. The outdoor variant is IPX5-rated for splash and rain. Battery runtime is reduced in sub-freezing temperatures but the device continues to operate.

What if it doesn''t work?

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