We get it. It sounds too simple. But PestZero doesn't kill pests — it changes the environment so they don't want to stay. The variable-frequency ultrasonic waves create conditions pests find intolerable. They leave on their own. No poison needed. No traps. Just plug it in and let the science do the work.
That's exactly why PestZero is different. Cheap devices emit one constant frequency. Pests adapt to it within days and simply ignore it. PestZero continuously cycles between 22–65 kHz — so pests can never adapt. It's the same reason a moving target is harder to ignore than a static one.
No. The ultrasonic frequencies PestZero emits are completely inaudible to humans. You won't hear a thing. You'll just notice fewer pests. Most customers forget the device is even plugged in.
Yes. No chemicals. No poison. No traps. Safe around children, cats and dogs. However, PestZero is not recommended for homes with hamsters, rabbits or birds — these animals have higher-frequency hearing that may be affected. If you have those pets, please do not purchase.
Not at all — this is completely normal. In the first 2–3 days, you may actually see more pest activity as they are disturbed and forced out of hiding. This is a sign the device is working. By days 3–4 sightings drop significantly. Most customers report a 70–90% reduction by day 7.
One unit covers approximately 300 sq ft. Ultrasonic waves cannot pass through walls, so you need one device per room for full protection. Most 2–3 bedroom homes need 3–6 units. Our bundles are designed around home size to make this easy.
A single exterminator visit can cost $400–$1,000. And that's often not a one-time expense — pests come back and so do the bills. PestZero starts from $29, runs for 4–5 years, needs no appointments, no chemicals and no repeated costs. One plug. Continuous protection.
Then you pay nothing. Every order is backed by a 90-day money-back guarantee. Full refund. No return shipping. No forms. No questions. Just email us. The only risk is spending another month sharing your home with pests.
PestZero is engineered to repel every common household pest.
Rats, roaches, mice, spiders, bed bugs — if it's invading your home, PestZero drives it out. If it doesn't, you get every dollar back.

Pests adapt to constant sounds fast. Most ultrasonic devices play the same tone — so within 14 days, pests ignore them. PestZero cycles between 22–65 kHz continuously. Pests can never adapt.

What Homeowners Are Saying
Safety
No chemicals.
No poisons.
No traps.
Most pest control means spraying stuff that's bad for you to kill stuff that's bad for you. PestZero is different — it uses ultrasonic sound that pests hate, but you literally cannot hear.
