Review on 🐭 12V Ultrasonic Under Hood Mouse and Rodent Deterrent for Vehicles - MouseBlocker by Shawn Welker

I am a professional mechanic specializing in automotive electronics. Mouseblocker is a well-made product that repels mice well. I installed it in my private car after I discovered a large mouse nest on the cabin air filter after trying dryer sheets. I couldn't use dCon due to pets in the house. The actual installation was very easy with just a little wiring. I installed it for a couple of weeks and all traces of the mice were gone. However, I would recommend a few things. The device and the supplied fuse are not weatherproof. I have it permanently installed under the hood and live in a place where salt is used on the roads 6 months a year. For the price, I personally wouldn't risk leaving a wire hole open in the unit and no all-weather fuse in such an inhospitable environment. However, it is perfect for winter storage. I used a dab of sealant to fill the hole for the wire and replaced the fuse holder with an weatherproof one as it is a 200mA glass fuse and blade fuses are not available for such small fuses. The device is still audible even with the top down, but it's very high-pitched and won't bother your ears or your pets. It's great for keeping mice out of your car and easy to install, even for those with very little electrical knowledge. .
