MouseBlocker PROx 12V – Under-Hood Ultrasonic Mouse & Rat Repeller for Cars, Trucks, RVs, Campers & EVs
Protect your vehicle’s wiring harness, hoses and insulation from costly rodent damage. Experience the varying and enhanced power of adjustable ultrasonic sounds, now 200 times more potent than the original model. These powerful sounds create an uncomfortable environment for rodents, discouraging them from nesting in your vehicle. Additionally, the MouseBlocker Pro incorporates two bright strobing LED lights, providing an extra deterrent that rodents despise.
Crafted with a robust all-aluminum alloy case, the MouseBlocker Pro not only safeguards our advanced microcomputer but also effectively dissipates heat. Installing this device is a breeze with its simple 2-wire hookup, connecting directly to your vehicle’s battery. Once your vehicle is parked and the engine is inactive, the MouseBlocker Pro springs into action, diligently protecting the area where it’s mounted.
Worry not about draining your battery excessively. Thanks to our intelligent microcomputer, seamlessly turns off when the vehicle is started as it senses movement, and if the battery voltage drops below 11V during idle periods (typically after around 10 days on a standard car battery), the unit shuts itself off to prevent excessive battery drain.
Operating at a mere 0.6 watts, the MouseBlocker Pro delivers remarkable power efficiency. We advise against using this model for applications that remain unused or uncharged for more than 10 days, as it prioritizes battery preservation and will shut it self off.
Upgrade to the MouseBlocker Pro and bid farewell to rodent infestations, knowing your vehicle is protected by cutting-edge technology and intelligent design.
Note: the NEW MouseBlocker PROx can be used now in all EV’s, Hybrids, RV’s and Campers and also with battery tenders and trickle chargers now as this unit now shuts down with movement and not battery voltage.
The NEW MouseBocker PROx unit will now work if you are using a battery maintainer for long term storage and want a 12V version MouseBlocker. We do recommend the Plug-In version though if you know this is going to be long term storage mostly.
Please see our 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 MouseBlocker Pro!!

My mother in laws Honda Accord is in the shop today having the main wiring harness replaced because mice or chipmunks chewed on the wires, at the cost of over $5000 dollars.
A few years ago my wires SUV had to have an oxygen sensor replace 3 times because a chipmunk had chewed on it, at a cost of $6000 a pop. They had to tear off the top of the engine to get to the sensor.
All of my vehicals sit outside and I occasionally see chipmunks climb in and out of the vehicles and I have had mice in the passenger cabin and had to set mouse traps.
The Honda service manager recommended this product and said he uses it successfully.
I am asking if any Freepers have used the product and their opinion.
Video at the site.
Ultrasonic mouse resellers don’t work. I tried them extensively over the last year in my home and camper.
I have tried things in the past like soap, dryer sheets, mothballs and other smelly things but I live in Northern Ohio where those things stop working when it gets too cold.
I need all temperature protection.
Ultrasonics work for a short period of time, then the critters get used to them. You are better off with traps or a hungry outdoor cat.
If it repels ‘RATs then perhaps they could be installed all over DC.
I have heard from others that they work for a short time and the mice get used to them and learn that they can ignore the noise.
Supposedly this one has several ‘songs’ that it plays intermittently and an intermittent LED strobe that is unpredictable and so the mice don’t get used to it.
So, I am looking for the opinion of someone that has tried this particular product.
I have one opinion from the service manager but I will have to buy 5 of these things if I am going to protect my cars and tractor. At $90 a pop that is, for me, a large investment to make on one man’s opinion.
Chech out post #7
The claims that they are so destructive to birds are exaggerated, and in some cases they are false to the point of being counterproductive.
You would have to install them in Northern Virginia and Maryland.
It would cost billions.
It also drive them in to other areas of the country. Look what happened to Texas when the Dems drove other Dems out of California.
I think it is a self defeating strategy.
“Ultrasonic pest repellers have limited effectiveness in chasing away rodents, as studies show that rodents often adapt to the sound over time and return to the area.”
Are used mice that low in quality? </humor>
My girlfriend had this installed on her RAV4 and it worked well. Hopefully they now have a rechargeable version that doesn’t require going in and changing the batteries.
I have at least two that frequent my yard.
I still ran over a mouse with my tractor (unknowingly). I am sure that the mouse had set up house in my tractor.
I found the freshly smashed mouse when I returned the tractor to its parking space.
I have a lot of nut trees in my yard and there is an over abundance of food for rodents.
I used to have a pair of Red Tail Hawks that helped keep the population down but they did not come back this year.
I also had at least one owl. But I have not heard it since spring.
This one is supposed to hook up to the car battery and has a battery monitor that turns the unit off if your battery gets low.
“Mouse Blocker Pro”. Barn cats are amazing at it.
I think these machines are cheaper than a barn, if they work.
I already have yard cats. Apparently they are bargain basement cats and aren’t getting the job done.
These powerful sounds create an uncomfortable environment for rodents, discouraging them from nesting in your vehicle.
I bet it's either Rap or Hip Hop.
Just play a loop of Yoko Ono’s Greatest Hits under your hood and that’ll probably make them skedaddle. No living creature could stand to be around that for very long. Then again, you might get charged for cruelty to animals.
I am sure you’re right, it would work.
But it would drive me away as well.
