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

This product worked wonders, easy to install and we got instant gratification the first night, no visible signs of rats in the engine bay.

Bought 2 on 3/19. Installed a few days later. Haven’t had a single mouse 🐁 in either of our 2 vehicles. I was concerned about power draw on the batteries but even if we allow our vehicles to sit in the 3-5 days they start with no sign of low voltage. Totally impressed

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.

So far so good. I'm using this in combination with the Vamoose Sent Packets & Spray. Rodents are really stubborn up here. Had to rewire two cars twice each. Costly! So far it's been a month now and no return calls from the mice and rats.

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 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.

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.
