Why people keep buying it

Quiet. Cordless.
Just works.

01

Silent to humans

22–55 kHz acoustic plus a low-frequency vibration pulse. Silent to you, your dog, and your cat. Spiders sense it through their leg hairs and route around it.

Finally a clean basement

"Used to find new webs in every corner of the laundry room every Monday. Set up Crittex on a Friday — by the next weekend the corners stayed clear. Haven''t seen a brown recluse in weeks."

No more shaking out shoes

"Two in the garage and one in the basement. I used to check inside every boot before putting it on. Now I just put them on."

Even the cellar is bearable

"Old house with a damp cellar — wolf spiders the size of half-dollars. They''re just... gone. Took about two weeks and we haven''t seen one since."

Cleaner than the bug guy

"Used to pay $60 every quarter for the spray service. Crittex is one-and-done and there''s nothing toxic in the air around the kids."

Quick answers.

How many do I need?

One Crittex covers up to 1,200 sq ft of unobstructed indoor space. Spiders prefer corners, basements, garages, and storage closets — place units in those areas first. Most homes do well with 2–3 units.

How long until spiders leave?

Most homes see fewer webs being rebuilt within the first week and a clear drop in spider sightings by day 14. Heavily infested basements can take up to 3 weeks.

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 work on every type of spider?

Crittex disrupts the cues that orb-weavers, wolf spiders, brown recluses, and common house spiders use to settle and hunt. It is not designed for tarantulas or scorpions.

What if it doesn''t work?

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