- Advanced Rodent Repellent Technology: The CIIC Rodent Car Repeller can simultaneously generate fixed-frequency ultrasound and variable-frequency ultrasound, as well as a strobe light, to stimulate the nervous system and auditory system of rodents, causing them to feel uncomfortable and run away from the scene
- Effective & Permanent Rodent Repellent: CIIC Animal Under Hood Repellent generates ultrasonic waves at a constantly changing frequency, which does not cause rodents to become “adaptive” or “immune” to a fixed frequency
- Higher Power Ultrasonic: The CIIC Rodent Car Repeller maximizes the power of the ultrasonic output to more effectively stimulate rodents, keeping them away from your car and protecting internal wiring from damage
- AUTO-SWITCH Function: when there is a vibration signal triggering the circuit (car start), the machine stops working. The red indicator light is always on. When the working environment of the rodent repeller is stabilized and no longer vibrates, the circuit resumes working after 90 seconds. When the vehicle is not in use, CIIC Rodent Ultra Sonic Strobe Light protects your car 24 hours a day
- Multi-Situation Application: 1. Wire connect to your vehicle's 12V battery located in the engine compartment for keeping your vehicle away from mouse. 2. USB direct charge for indoor use
