Buying Guide
How many units should I use?
For small rooms, one unit may suffice. For open or multi-room spaces, deploy one unit per major area to account for wall attenuation and to ensure consistent coverage.
Which mode should I pick?
Mode selection depends on the pest profile and tolerance for noise. Start with Mode 1 for quiet operation, then try Mode 2 or 3 if pests remain active and the space is unoccupied.
Do ultrasonic repellents work around pets and children?
Generally safe for humans and most pets when used as directed. Some individuals or animals may be sensitive to ultrasonic sounds. If any discomfort occurs, switch to a lower frequency or reduce exposure by increasing distance from occupants.
How long before I see results?
Most users notice a reduction in pest activity within 2–4 weeks with consistent use. Results vary by pest pressure, room layout, and the number of units used.
What’s the best practice for placement?
Place units in a central wall outlet, elevated 2–3 feet above the floor if possible. Keep units away from obstructions like large furniture and ensure continuous power supply for uninterrupted protection.
