You parked it, covered it, and want it mouse-free come spring. This 12V deterrent helps with that, using sound and light to make your RV or boat less inviting to critters looking for a winter home.
Whether you're parking an RV, boat, or lawn equipment for the off-season, this compact deterrent helps discourage mice and other small animals from getting too comfortable in your space and equipment. The MouseBlocker PROx is ideal for enclosed, low-light areas like RV and boat engine compartments, battery boxes, lawn and farm equipment, motorcycles, ATVs, and other 12V-powered gear. It's also a good fit for electric and hybrid vehicles with 12V battery access. Because you can use this with a battery maintainer, it's a great fit for the vehicle you use for your daily drives or vehicles, like tractors and mowers, you use once a week. If you know your vehicle is going to be in storage, unused for weeks or months, we recommend the plug-in version (MB34FR).
MouseBlocker PROx uses ultrasonic sound in an intermittent pattern and dual strobing LED lights to make dark, enclosed spaces less inviting, and performs best in spaces where sound and light can bounce off surrounding surfaces. You can choose from three output levels depending on how aggressive you want the deterrent to be. Because these sound levels are at a frequency humans can't hear, you won't notice a thing. The unit runs continuously, shifting between frequencies of 25 to 45kHz. This intermittant pattern helps keep mice from getting used to a single, constant frequency. It connects to a 12V battery, but only takes about as much power to run as an LED nightlight, and is smart enough to shut off automatically if voltage drops below 11V.

Well I'm not sure it's 105 DB. We have another one of not this brand that have less decibels and is louder. Whether or not it works, that remains to be seen.
Easy installation waiting to see the re sults
So far so good. Pack rats gone. Mine does not seem to shut off when the truck starts. Possible it shuts off after the truck moves but I would have no way of knowing. Does not shut off when parked and running.
Easy to install. Easy to order, communication was great and was delivered in 3 days. I’ve never had a problem with etrailer or their products.
It seems to be doing its job.I haven't seen any sign of a mouse being under the hood I also put Grampa gusses mouse pouch there
I bought the units to keep squirrels out of my engine compartments. Too early to tell if they are working
I have two and I just received two more I use them in our 5th wheel except one I will hang on one of the axles under the trailer to deter other critters
