Click for MouseBlocker PRO Installation Manual
The MouseBlocker Pro is the most advanced rodent deterrent available for your vehicle. The MouseBlocker Pro takes everything great about the Original MouseBlocker and makes it better. The Powerful Ultrasonic Sounds emitted from this unit are now adjustable and now even louder than the Original. This new unit also adds a new deterrent in the form of 2 Bright Strobing LED lights simply adding another feature the rodents do not like in our attempt to make the area very uncomfortable for the rodents to nest.

Our All Aluminum Alloy case is designed to protect our new advanced microcomputer and dissipate heat. Simple 2 Wire hookup wires directly to the vehicles battery. When the vehicle is parked and the engine is not running the MouseBlocker goes to work to protect the area you have it mounted. Once you start the vehicle our microcomputer will automatically sense a change in voltage and turn the MouseBlocker Pro OFF. While sitting if the battery voltage drops below 11V the microcomputer will also shut the unit off as to not drain the battery too low (this takes about 10 days on a standard car battery).

The Mouseblocker PRO is very powerful and uses .6 watts of power to operate.  The unit will shut itself off to protect the vehicles battery when voltage drops to 11V, this usually takes about 10 days on a standard car battery.  We do not recommend this model for use on applications that sit for more than 10 days without reuse or charging. 

Please see our NEW Plug In PRO Model for a long term storage solution.

Use what the Pros use:  This product is sold at hundreds of New Car Dealerships, Parts stores, tractor and motorcycle dealerships throughout North America!!  Protect your vehicle today with the NEW MouseBlocker Pro!!

Note: This unit is LOUD and on the highest settings most humans can hear the sounds emitted as will some household pets like cats and dogs. The sounds WILL NOT harm them in any way you will just notice the animals will leave the area the unit is located and if under the hood of your vehicle the sounds for the most part will be contained to the engine compartment anyways.

    I purchased one last year and it solved the problem of mice setting up
    house in my nice warm engine compartment. Really does the job and
    worth every penny, also very easy to hook up!

    We purchased a MouseBlocker Pro a little over a year ago. This unit worked great and kept the mice out of the engine compartment of our Dodge truck.

    For some reason it stopped working. I called MouseBlocker and talked to a gentleman by the name of Matt. He was very cordial, polite and concerned about the malfunction.The end result, Matt very generously replaced the unit free of charge.

    MouseBlocker stood behind their product 100%. I highly recommend the product and by all means the company. Sincerely, Bob Jensen

    Purchased about a month ago after experiencing mouse hibernation in my AC/Heater blower unit for the second year in a row. This has been a costly problem for me replacing these parts at a combined $700 cost! Prior to installing the Mouse Blocker, I had seen evidence of acorn storage (chipmunks?) near the latch area of the hood. The mechanic advised using dryer sheets, chopped up pieces of Irish Spring soap and/or peppermint oil to help deter the rodents. I haven’t noticed any activity since installing the Mouse Blocker. Confident thus far that this will be the solution.

    Hi. We live on a farm thus many mice. We tried numerous methods to deter mice…ie, peppermint oil, irish spring, dryer sheets, mothballs, lights… these seem to work however signs of mice activity returned. Mice go throughout entire vehicle where they cannot be seen such as headliners, within panels, under carpets, EVERYWHERE. As we found out mice are extremely unpleasant, smell as well as unhealthy and dirty. We recently had major repair due to mice in 2 out of our 3 vehicles. THOUSANDS covered by insurance as well as THOUSANDS out of pocket. We have tried other ultrasonic products in which did not work as activity (poop) was right beside unit. We tried the Mouseblocker Pro after googling and reading good things. It has worked great in the vehicle as well as the surrounding area. Since becoming aware that it does work, we purchased 4 more and use in all vehicles with spares as am now freaked out of being without this protection. I do not write reviews, however after using the unit and receiving such good customer service with them immediately answering all my questions, I felt that I would write something. Thx.

    Mice loved my wife’s vw Jetta to the tune of almost $1000.00. Tried all the smelly deterants to no avail. Mouse blocker has worked!!! I bought 3 more. One was damaged and was cheerfully replaced. GREAT PRODUCT, GREAT COMPANY!!!!!!
