The device is typically called a rat repeller, often marketed as an ultrasonic rodent repeller.

What is the device that repels rats called? - in detail

The apparatus designed to deter rodents is commonly referred to as a rat repeller. It operates on principles that discourage rats from entering or remaining in a specific area without causing harm.

Typical rat repellers fall into three categories:

  • Ultrasonic emitters – generate high‑frequency sound waves beyond human hearing that cause discomfort to rats’ auditory system.
  • Electromagnetic devices – produce low‑frequency electromagnetic fields that interfere with rats’ nervous activity, prompting avoidance.
  • Scent‑based deterrents – release natural or synthetic compounds (e.g., peppermint oil, predator urine) that rats find aversive.

Key specifications to consider when selecting a unit include:

  1. Frequency range – ultrasonic models should cover 20–65 kHz; higher frequencies increase effectiveness against juvenile rats.
  2. Power output – measured in milliwatts; sufficient intensity ensures coverage of the intended space.
  3. Coverage area – expressed in square meters; larger premises require multiple units or a higher‑power model.
  4. Power source – options are mains‑connected, battery‑operated, or solar‑driven; choice depends on installation constraints.
  5. Safety features – automatic shut‑off when humans or pets are detected, to prevent unintended exposure.

Installation guidelines are straightforward: mount the unit at a height of 1–2 m, point the speaker or emitter toward open pathways, and avoid obstructive surfaces that could reflect or absorb the signal. Continuous operation is recommended for sustained deterrence; intermittent cycles may allow rats to habituate.

Maintenance involves periodic cleaning of the exterior to prevent dust accumulation, checking battery levels if applicable, and verifying that the device remains within its specified temperature range. Performance can be evaluated by monitoring rodent activity signs—droppings, gnaw marks, or audible noises—before and after deployment.

In summary, a rat repeller—whether ultrasonic, electromagnetic, or scent‑based—provides a non‑lethal method to keep rats away, provided it is correctly specified, installed, and maintained.
