Most of those emit a single constant frequency that pests adapt to within 7–14 days. PestPro uses variable-frequency cycling between 22–65 kHz so pests can't habituate. We also use industrial-grade components designed for 4–5 years of continuous operation, and back it with a 3-month guarantee instead of 30 days.

Yes for cats and dogs — they can't hear ultrasonic frequencies above 20 kHz. PestPro is not safe for hamsters, gerbils, rabbits, or birds, which have higher-frequency hearing. If you own any of those, please don't purchase.

One unit per room. Ultrasonic waves cannot pass through walls or solid materials, so coverage is room-by-room. Most American homes need 4–6 units. Our most popular bundle is the Home system (4 units) for 2–3 bedroom homes.

Most customers report a 70–90% reduction in pest activity by day 7, and a fully pest-free home by day 14. You may temporarily see more activity in the first 2–3 days as pests are forced out of hiding — this is normal.

You're risking $29 to potentially save thousands on exterminators. We're risking $29 every time someone doesn't see results. That's why we keep improving the device — and why we offer one of the longest guarantees in the category. 12 months, no forms, no return shipping, just email us and we refund every dollar. We're betting on the science. You bet on us.

We sell directly to consumers to keep prices accessible. The same quality device sold through retail chains would cost 2–3× more due to distributor markups. By staying DTC, we can offer pro-grade technology at consumer prices.
