Rodent Repeller GreenBlue GB725 ultrasonic device GB730/GB725 compact design

GreenBlue GB725 (GB730/GB725) is a compact ultrasonic rodent repeller designed for use in vehicles and other small spaces. The device produces high-frequency sound waves intended to deter mice and rats without the use of poisons or mechanical traps. Its compact design allows placement in engine bays, trunks, or passenger compartments to reduce the risk of rodents damaging wiring, insulation, and other vehicle components.

Advantages

The GB725 offers chemical-free protection using ultrasonic pulses that are aimed at creating an uncomfortable environment for rodents while remaining inaudible to most humans. Its small footprint and lightweight construction make it suitable for limited spaces and straightforward to install. The device operates continuously when powered, providing around-the-clock deterrence without ongoing maintenance or consumables.

Suitable for

• Protecting vehicle engine bays, trunks and wiring looms from rodent damage
• Use in small storage compartments, sheds or workshops where space is limited
• Short-term protection of parked vehicles, recreational vehicles and boats
• Areas where chemical baits or traps are not desirable or permitted

Key specifications

• Type: ultrasonic rodent repeller
• Form factor: compact, lightweight unit for confined spaces
• Operation: continuous ultrasonic emission when connected to vehicle power
• Mounting: designed for placement in engine bay, trunk or passenger area; may include clips or mounting points depending on installation
• Power source: vehicle electrical system (12 V DC typical)
• Effectiveness: intended to deter common rodents such as mice and rats through high-frequency sound

How to use

Place the GB725 in the area to be protected—common locations are the engine compartment, trunk or under-seat areas—ensuring it is secured away from moving parts and excessive heat sources. Connect the unit to the vehicle power supply according to the manufacturer’s installation instructions and verify the device powers on. The device is designed for continuous operation while the power connection is active; routine visual checks are sufficient to confirm installation integrity.

Usage recommendations

Install the repeller in the most probable rodent-entry area and avoid obstructing the device with insulating materials or dense covers that could reduce ultrasonic dispersion. For best results combine placement in multiple locations if practical and routinely inspect wiring and mounting to ensure continued operation. This device is intended as a deterrent and may be less effective in areas with heavy rodent infestation or where food sources are abundant.
