Ultrasonic rodent repellers are a growing category in the pest control market. Unlike traps or poison, they are chemical-free, safe for pets and reusable — which makes them appealing to environmentally conscious buyers.

1. How they work

Ultrasonic repellers emit high-frequency sound waves (usually 20–65 KHz) that are unpleasant for rodents but inaudible to humans. Some models also emit electromagnetic waves to disrupt rodent nervous systems.

2. Frequency range

  • Single frequency — cheaper, but rodents adapt within weeks
  • Variable frequency — sweeps across a range, prevents adaptation
  • Dual ultrasonic + electromagnetic — best effect, premium price

For repeat purchase and good reviews, always choose variable frequency models.

3. Coverage area

  • 100–120 m² — single room use
  • 160–200 m² — whole apartment or small warehouse
  • 300 m²+ — commercial or industrial spaces

4. Pet safety

Repellers are safe for cats and dogs because their hearing range partly overlaps but the sound is not painful. However, they can affect hamsters, guinea pigs and rabbits — which hear higher frequencies. Always note this in the product listing.

5. Features that sell

  • Adjustable frequency modes (3 levels is standard)
  • LED indicator showing mode
  • Night light function
  • Low power consumption under 3W
  • EU / US / UK plug options

6. Certification

  • US — FCC, ETL (if plug-in)
  • EU — CE, RoHS
  • UK — UKCA

7. What to stock

  • 1 entry-level single-frequency — for price-sensitive buyers
  • 1 mid-range variable frequency — the core best-seller
  • 1 premium dual-wave with coverage 200 m²+ — for warehouses
