Loraffe Ultrasonic Under‑Hood Rodent Repellent for Cars, Trucks & RVs — 12/24V, LED Strobe & Low‑Voltage Cutoff

Loraffe Ultrasonic Under Hood Rodent Repellent is a compact, under‑hood electronic device that uses variable ultrasonic frequencies and flashing LEDs to discourage rats, mice and squirrels from nesting in vehicle engine bays.

Parked vehicles, trucks and RVs are prime targets for rodents that chew wiring, insulation and hoses. The Loraffe under‑hood repellent combines shifting ultrasonic pulses with a visible strobe pattern and smart power management to make the engine compartment an unattractive place for pests without chemicals or traps. It installs directly to the battery with two wires and runs automatically when the vehicle is stationary.

How does this device deter rodents under my hood?

The repeller emits variable-frequency ultrasonic waves that rodents find uncomfortable and pairs those sounds with intermittent LED strobe flashes to reinforce avoidance. The non‑harmful signals disrupt nesting and chewing behavior without poisons or sticky traps.

• Variable ultrasonic frequencies cycle to prevent habituation.
• Flashing LED strobe adds a visual deterrent in confined engine spaces.
• Continuous operation while parked keeps animals from returning.

Will it drain my vehicle battery or affect starting?

Loraffe includes a low‑voltage cutoff and an auto‑standby mode that protect your battery. The unit automatically stops when voltage falls below a safe threshold and suspends operation while the vehicle is moving, resuming after vibrations cease.

• Automatic low voltage cutoff around 10.7V (+/‑0.2V) prevents excessive draw.
• Standby during driving reduces unnecessary power use.
• Suitable for vehicles with accessible 12V or 24V engine‑bay batteries.

How simple is the installation and what tools are required?

Installation is designed for DIY fitting: connect the two provided wires to the battery terminals and secure the unit under the hood with the included zip ties. No complicated wiring harnesses or professional installation is required for most cars, trucks and RVs that have engine‑bay batteries.

• Two‑wire connection to battery positive and negative with spade connectors.
• Zip ties included for secure mounting near wiring looms or air box.
• Basic hand tools recommended: pliers and a wrench for battery terminals.

What vehicle types and battery locations are compatible?

The repeller is intended for vehicles whose battery is located in the engine compartment and accessible for direct connection. It is not suitable for vehicles with batteries in trunks, under seats, or beneath floorboards where the device cannot be mounted under the hood.

• Compatible: cars, trucks, SUVs and many RVs with engine bay batteries.
• Not compatible: vehicles with remote battery locations or inaccessible terminals.
• Works with both 12‑volt and 24‑volt systems when connected correctly.

Who is this for: Loraffe’s Ultrasonic Under Hood Rodent Repellent is aimed at drivers, fleet managers and RV owners who want a low‑maintenance, non‑toxic way to reduce rodent damage. Choose this unit if you park outdoors, have experienced gnawed wiring or insulation, and need a compact device that installs quickly to the engine bay and manages battery usage automatically.
