Vehicle rodent deterrent

The MouseBlocker Classic is an ultrasonic pest control unit designed for 12 V electrical systems in cars, trucks, motorcycles, boats and other equipment. It targets mice, squirrels, voles, chipmunks, rabbits and similar rodents that nest in engine compartments and chew wiring.

Direct battery connection

A two‑wire hookup to the vehicle battery eliminates replaceable cells and ensures continuous operation without checking flashlight batteries. The unit draws only 0.1 W, so it protects stored or daily‑driven vehicles for extended periods without draining the battery.

85 dB ultrasonic output

The emitter produces an 85 dB tone in a frequency rodents perceive as a jackhammer, making the engine bay uncomfortable for nesting. Coverage is limited to the immediate under‑hood area; larger structures or multi‑compartment spaces may need additional units.

Questions about this item

Does the ultrasonic emitter degrade and need replacing after a certain period?

The solid-state ultrasonic emitter has no moving parts and is designed for continuous 12V operation without a scheduled replacement interval.

What limits how long the unit can run continuously from a vehicle battery?

At only 0.1 watts draw, the practical limit is the battery's own state of charge rather than the device, so it can run indefinitely on a healthy 12V system.

Can you hear the 85 dB ultrasonic output or feel heat from the unit while it runs all day?

The 85 dB signal is above human hearing range, the unit produces no audible noise and no noticeable heat during continuous operation.
