How does an ultrasonic pest repeller work?+
Each unit emits high-frequency sound waves (20–65 kHz) that are inaudible to humans and most pets, but disturbing to the auditory and nervous systems of common household pests. Pests become uncomfortable in the area and gradually leave to find quieter habitats. The repeller works continuously while plugged in.
What pests does it repel?+
The Pest Repeller is designed to repel mice, rats, cockroaches, ants, spiders, mosquitoes, flies, fleas, and bed bugs. It is most effective against insects and small rodents that have sensitive hearing in the ultrasonic range.
Will it harm my pets?+
No. Cats and dogs hear higher frequencies than humans, but the wave patterns and intensity used by the repeller are tuned for pest neurology, not pet hearing. Hamsters, rabbits, and other small rodent pets should be kept in a different room as a precaution.
How long until I see results?+
Most customers notice a reduction in pest activity within 1–2 weeks. Full effectiveness typically takes 3–4 weeks, as pests permanently abandon their nests and stop returning. You may actually see more pests during the first week — this is normal, as they are being driven out.
Do I need one in every room?+
Yes. Ultrasonic waves do not pass through walls — each unit covers approximately one room (up to 1,200 sq ft). The 6-pack is designed so you can place one in each major area of your home: kitchen, garage, basement, bedrooms, etc.
Will I be able to hear it?+
No. The waves operate above 20 kHz, which is the upper limit of human hearing. The unit operates completely silently from your perspective. The blue LED indicator simply shows it's powered on.
Does it use a lot of electricity?+
No. Each unit consumes only 3–5 watts. Running all six 24/7 costs roughly $0.50/month total in most US states.
What's the warranty?+
Every unit comes with a 30-day money-back guarantee. If the repellers don't work for you, send them back for a full refund — no questions asked.
How do I install it?+
Plug it into any standard US wall outlet. The blue LED will turn on automatically. That's it — no setup, no batteries, no apps. Place each unit in an open area, away from large furniture or thick fabric that can block sound waves.
Will it work in a basement, garage, RV, or shed?+
Yes. Any space with a standard 120V US outlet works. The unit is designed for indoor or covered outdoor environments. Avoid placing it where it can get wet.
