Mouse Blocker Prox 12Volt High Powered Ultrasonic Mouse and Rodent Deterrent with with an Eviction Mode and Dual Strobing LEDs for Your Vehicle

Only have been using it for about 10 days but appears to be working. Easy to install and set up, No rodents have been encountered in the engine bay and hope it stays that way.

I have 2 of these mounted on the firewall, 1 in my ‘07 Sequoia and 1 in my ‘18 Rav4. They work well. However, they will drain the battery down after a few days on the high setting. I’ve killed hundreds of mice with snap traps over the years around my vehicles and home. I have a mouse blocker pro in my boat that is powered by an ext cord. They work well. Just when I think I’ve got them all, I find more in the traps. It’s hard to keep up. Bucket traps with water don’t work in the winter. Lol. I also undercoat my vehicles with NHOU that has a peppermint additive to it. That stuff works amazing at keeping them out of our vehicles. The mouse blocker helps keep them out of the engine bay. But I’ve found chewed paper inside the car a couple times even with the blocker on high and in between coatings. I’m a Master Toyota technician and I’ve repaired hundreds of cars. I’ve seen the worst you can imagine. These measures help dramatically, but nothing will stop them from getting in except killing them in traps. It’s an ongoing battle that never ends.

My company vehicle wasn't turning on. Turns out the engine wires were chewed to bits. After a $500 repair bill, my workplace purchased this product. Haven't had any wire chewing since! My personal vehicle frequents the same property. Many months later my headlights stopped working, I popped the hood open and found the headlight wires chewed to bits. After my $200 repair bill, I ordered the same product for my personal vehicle. No mouse droppings or wire chewing has occurred in either vehicle since their respective installation of this product. Over a year later, the product that was in my personal vehicle started to make gargled electronic noises instead of it's usual routine. I contacted the seller who was quick to respond! He gave me info to do a hard reset, unfortunately, it did not solve the issue. After letting the seller know this, he was quick to send me a replacement! The replacement is protecting my personal vehicle well, and the company vehicle's product is still going strong. Thank you for not only a great product, but for assisting me as well!

I have had issues with squirrels, mice, rats, you name it, chewing up the wiring on my vehicles. I purchased 1 Mouse Blocker Pro 12v to test out. No more damage, no paw prints in the dust, it appeared to be working, so I purchased a second Mouse Blocker Pro 12v, and installed it a few months ago. Those both came in the same packaging, which is what you see in the right side of the photo's I have attached. I bought a 3rd one about a week ago. The 3rd arrived, but on the box has Mouse Blocker ProX, the packaging is the same, except the the printing on the outside is different, and the printing on the actual device is different. The enclosed product installation and operation guide is the same as the previous 2. I installed the 3rd Mouse Blocker ProX, the documentation and description states the device shutoff when the vehicle is started, the voltage is low, and has the same install instructions. I installed it, and found there are some differences in the Mouse Blocker ProX, I had to do my own research and testing to figure out why the device I received didn't work like the previous 2. The manufacturer appears to have updated the device, or it is a new one, and does not operate like the previous 2 I purchased. Both turn on/off, have 3 levels of sound, and connect to the battery the same. The ProX however, does not shut off when the vehicle is started, and I noticed when I was installing it, if you move the ProX, it appeared to shutoff. At first I thought the unit I had was defective, but some testing I discovered if the device is moved, it shuts off, I had use a camera under the hood, start the vehicle, and start driving, it shut off, which explains why the device did not shutoff when I started the vehicle. I wonder how many are being returned due to the outdated documentation? If you purchase one, be aware there appear to be 2 models, the Mouse Blocker Pro, and the Mouse Blocker ProX. The documentation they send is for the Mouse Blocker Pro, not the ProX. The box on the ProX does not mention it shuts off if the voltage drops below 11.5v, and since it lacks documentation I am not sure if it does, or does not, I may wake up one day to a dead battery, ,which is when I will find out if it shuts off below 11.5v. The Mouse Blocker ProX does not shut off when the vehicle is started, I appears if the device detects movement, it shuts off. I am assuming this as it's my observation from watching it when I move the vehicle from point A to point B. It appears to start working again when the vehicle is no longer moving. I deducted a star due to the lack of documentation on the ProX, is it an update, a different version, they have different applications, like an electric vehicle, or can they be used on both combustion and electric vehicles? Only time will tell if it is as effective as the previous purchases.

I found my husband purchasing this product after a trip to FL in the winter (we live in NJ). After returning home, upon starting our car, the hood started smoking. Squirrels had taken up residency in the hood of my honda accord. They bit some electrical wire and had tons of sticks and leaves in their new apartment. We tried moth balls and that did not work. My husband purchased this product and no more squirrels!!! Our neighbor was having the same problem and we sent them this to buy and they too no longer have squirrels. Since 2019 we have bought 4 of these (new cars and husband forgot to remove from a car we traded in). We can say enough good things about this product. Knowing we arent hurting the squirrels with this puts my animal loving self at ease. Yes its a little expensive but rather spend the money on this than thousands of dollars on my car due to electrical issues from the squirrels eating the wires.

Purchased this to help or hope to control field mice in my car. Installed and tested, no issues. I set the loudness at the highest level. I drive this car installed in appx 2 times a week. It has not deterred the mice in the car. I mounted it under the hood and after no success, I mounted it in the back near the spare tire. Each location has shown signs of mice activity. This unit has killed my 6 month old brand new Interstate battery 3 times. Enough where I intentionally start the car to charge the battery. (It does not stop operation at 11.8 volts as advertised, as my car will not start)

I don't like reading crazy sounding reviews that seem like they are written by the company that sells the product; I have to make an exception in this case and write one of my own. We moved to the top of a mountain this past March, and no one warned us about all of the mice. There aren't enough predators to keep them at bay, and they frigging INFESTED our cars in the driveway after a month of moving in. By the time we noticed, the mice had taken insulation and padding from the seats and created huge nests in the engine bay, trunk, dash, EVERYWHERE. We freaked out since it was our first time experiencing anything like this and read online for solutions. We battled them *all* year up until last month when we bought these MouseBlockers. We tried every stupid thing you've ever read on the internet to prevent mice. Irish Springs soap (they ATE it), mothballs (they didnt mind - we wanted to die), pure peppermint oil (seemed to work for short periods of time, but they immediately came back even with constant spraying. This also made our eyes water we sprayed it so strong). I finally resorted to live traps. I would catch a mouse here and there and take them down the mountain and release them. the problem with this is that if there's 1 mouse, there's thousands. You could catch a mouse every day, and there's thousands more to replace it. Do you want to kill or live trap mice every day forever? I also read online and youtube about sonic devices and how they don't actually work for mice, so I was highly skeptical these would work. I was at my last nerve with mice running all over the car while I drove down the mountain so I was willing to give anything a try. THANKFULLY I can say that after 1.5 months of using this, the mice are GONE! I knew it was working the first weekend we installed the because we would see mouse droppings every single morning in the cupholders and dash as well as live mice in the traps. This was instantly gone after the first weekend. Now that it's been almost 2 months with them, it's all just starting to feel like a bad dream and I can finally review this. I can't recommend these highly enough. For anyone that knows the feeling of seeing mice dart around the car while you drive, you know that it's unnerving experience. The install is super easy. Make sure you try to find a spot somewhat close to the battery because of the short wires, CLEAN the flat spot you pick with de-greaser and then alcohol, and use a high temp heavy duty double sided tape like loctite red. Use 4 strips (2 vertical following the side mounts - 2 horizontal along the fins). You can also use the holes and screws but it's harder to find a mount point and possibly have to drill. Also, put it in a spot where you know you'll get maximum reverberation in the engine bay (don't put it next to or against a padded insulation piece). I know this was long, but it really saved us big time. Luckily the mice had just damaged insulation/seats etc and hadn't ruined the engine wiring yet except for my blinker light wires. We have them set to the highest setting (loud and blinking LED's). I can hear them, our younger friends can definitely hear them, but older people can't hear that frequency as well. As long as the mice stay away, I don't care!

Last year, a rat infestation caused over a thousand dollars of damage in the engine compartment of one of our vehicles. What followed was an extensive trial and error period of oft-noted solutions involving peppermint oil, various spices, laundry drier sheets, cheap noise makers, etc., but the rats always came back. After much depression, discussion, and considerable research, we discovered the Mouse Blocker line of ultrasonic products, which, as we learned, is successfully used by ranchers and farmers, car dealerships and municipalities, and countless car enthusiasts, among others. So we purchased a 12v hard wired Pro model, had it professionally installed, learned how to use it, and shortly thereafter, a bit more than a week, the rats were no longer interested in that car! We now employ several Mouse Blocker Pro devices to protect our vehicles. Not long ago, the same model device, newly installed on another of our cars, began to fail pretty quickly. I called Matt Swift, the owner of Mouse Blocker, and he guided me through the process of testing and resetting the unit, after which we determined that the unit was dying. Matt very kindly, and quickly, sent out a replacement unit, which, after proper installation, works perfectly. Thank you, again, Matt! The Mouse Blocker Pro has alleviated a major headache in my life, and I highly recommend it. This product does not fall into the category of one of those crazy one-note high-pitched toys-- This a high-quality device that appears to do as it is intended, and it is supported by a company that understands what service means.
