Features to know about

For Indoor Storage and Seasonal Protection

Whether you're storing an RV, parking it in the garage, or stashing gear in a shed, this plug-in deterrent helps discourage mice and other small animals from getting too comfortable. The MouseBlocker PROx is ideal for enclosed, low-light areas like RV interiors, garages, basements, sheds, or indoor storage units with access to a standard outlet.

How It Works

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. The unit runs continuously while plugged in, and you can turn the lights on or off with the built-in switch for flexible operation.

Looking for small, easy to hide device. These fit the bill!



by:

Yes it works out great and going to be getting another one soon!



by:

This little device is simple to install. The combination of sound and light should do the trick to keep rodents out of the rig. This is much easier than using those smelly pouches, and you don't need to buy a new one every year.



by:

So far so good, thinking about buying more. Haven't heard or seen a mouse since I bought one and I had a serious problem before.



by:

Easy to setup and use. Too soon to tell if it keeps the mice away.



by:

Works great! Highly recommend.

Works as described and arrived fairly f ast.

  • What Is The Square Footage The MouseBlocker PROx MB34FR Will Cover?
    Hi Donald! The MouseBlocker PROx Plug In Electronic Rodent Deterrent - 110V AC # MB34FR is rated to protect up to 400 square feet. However, it is mostly intended for direct protection and not necessarily a large area. Think vehicles, trailers, and even some Class A motorhomes (depending on their size). That kind of thing. What are you thinking about using this for? Other than keeping pesky rodents away, of course.

  • What is Wattage of MouseBlocker PROx Plug In Electronic Rodent Deterrent # MB34FR
    Hey Bruce, the wattage rating for the MouseBlocker PROx Plug In Electronic Rodent Deterrent # MB34FR that you referenced is 12 watts.

  • Is The MouseBlocker PROx MB34FR Safe For Dogs And Cats?
    Hello Dewey, good question. The MouseBlocker PROx # MB34FR is designed to be safe for pets. The device does emit a high frequency sound and the consensus is that most pets are unbothered by the sound. That said, some pets are more sensitive to the sound than others. It is recommended to monitor your bets behavior when you first install the blocker. If they seem more distressed or nervous than usual, you should discontinue use.

  • Protecting Stored Camper in Open Garage From Pests Like Mice And Rats
    Jordan, yes, the 360x # MB64FR is designed for larger enclosed spaces like barns and pole sheds. It throws ultrasonic sound in all directions, covers up to 1,000 sq. ft., and even has a weather-resistant case for barn environments. For extra protection inside the camper, some owners add a plug-in # MB34FR in the living space. Do you plan to keep the Catalina plugged into shore power, or just dark storage? And don't worry, these devices only scare the rodents off, but they don't actually...

  • Using Multiple MouseBlockers in a Fifth Wheel RV To Prevent Pests From Entering
    Janice, a single # MB34FR plug-in covers about 400 sq. ft., which is enough for one section of your Montana. Because sound waves don’t pass through walls and cabinets, many RV owners install two units - one up front near the bedroom and another in the living/kitchen area - for full coverage. If you’ve got basement storage, a Classic # MB44FR tied to the battery is a smart add-on too. Do you want full-coach coverage or just the living area?

  • Best MouseBlocker Pest Control for Small Garage With Tools (safe for dogs and cats)
    Dennis, for a one-car garage, the plug-in # MB34FR is plenty - it covers up to 400 sq. ft. and is simple to plug in and forget. The 360x # MB64FR is better for big shops or barns, but in your case, the smaller unit will get the job done without overpowering. These are also safe for dogs and cats, whereas some other pest control methods may not be. Do you store any vehicles in that garage too, or just gear?

  • How To Deter Pests And Rodents For Long-Term Vehicle Storage Without Battery Maintainer
    Carl, exactly. The Pro # MB94FR works best when the vehicle battery is maintained or charged at least every week or two. For long-term storage without a maintainer, the plug-in # MB34FR is safer - it runs continuously off a 110V outlet and doesn’t risk draining your Jeep’s battery. Do you have access to power in your storage spot, or is it totally off-grid? If you don't have power outlet at all, the lowest wattage unit that runs off your Jeep's 12v battery is the classic # MB44FR, using...

  • Using Mouse Blocker Pro in a 2009 Fleetwood Discovery to Prevent Rodents
    Greg, the Pro MouseBlocker # MB94FR is an excellent choice for large Class A diesels. It wires right to your 12V battery bank, adds flashing LEDs for extra deterrence, and shuts off automatically if voltage drops below 11V. Since you’ve got a big rig, many owners install one Pro unit in the engine bay and a plug-in # MB34FR in the coach interior for full coverage. Do you keep your Discovery plugged into shore power in storage, or just let the batteries sit? If you have power all the time,...

  • Mice Getting Into Basement Compartment Of 2021 Grand Design Reflection Fifth Wheel RV
    Lisa, the basement is a perfect spot for the Classic # MB44FR. It tucks right into that enclosed space, wires to the 12V system, and keeps rodents away from wiring, insulation, and stored gear. It also draws such low wattage (.1w) that your battery system won't even notice it's there. Some RVers also add a plug-in # MB34FR inside the living space if they’ve got shore power, for whole-coach coverage. Do you usually keep the Reflection plugged in during storage?

  • Electronic Device For Protecting Lawn Equipment Stored In Garage From Rodents And Pests
    Nancy, the plug-in # MB34FR will discourage rodents from hanging out in the garage overall. But if you want to specifically guard the snowblower, the Classic # MB44FR wired to its 12v battery is more direct protection. Many folks do both - one plug-in for the space, one Classic on key equipment. Do you keep other power tools in the same garage?

  • Choosing Between Plug-In and Wired 12V MouseBlocker for RV Interior
    Kevin, if you’ve got access to shore power while your Jayco’s parked, the plug-in # MB34FR is the easy choice - just plug it into a standard outlet inside the camper, and you’re protected. If you store off-grid without power, the Classic # MB44FR can be wired to the trailer’s 12V battery system instead. Both use ultrasonic waves that bounce around the interior and keep mice from getting comfortable. Do you normally have your camper plugged in when it’s in storage, or is it off the grid?...

  • Best Rodent Deterrent for Classic Car Stored Indoors
    Tim, either will work, but here’s the difference: the Classic # MB44FR wires right to the Mustang’s 12V battery and protects the engine bay specifically. The plug-in # MB34FR, on the other hand, treats the whole garage space as long as it’s enclosed and under 400 sq. ft. A lot of classic car guys run both - one in the car, one in the garage. Do you keep your Mustang’s battery connected in storage, or do you normally disconnect it? Any other car collectors here run MouseBlockers?

  • How To Deter Rats And Rodents From Engine Bay Of Honda Accord
    Emily, since your Accord is parked outside, the plug-in # MB34FR in the garage won’t help much - the ultrasonic waves don’t carry outdoors. You’ll want the Pro # MB94FR wired to your Honda’s 12V battery under the hood so it runs whenever the car’s parked. It uses almost no power and even shuts off if battery voltage dips too low. Do you usually park under a cover or just open air?

  • Best Option For Pest Deterrent When Storing Class A Motorhome Indoors
    Karen, since you’re indoors with access to power, either could work. The plug-in # MB34FR is plenty for protecting the motorhome interior itself up to about 400 sq. ft. If you want broader coverage for the whole storage unit around the RV, the 360x # MB64FR would be the way to go - it throws sound in all directions and covers about 1,000 sq. ft. There's also nothing wrong with grabbing both units for the best protection inside and outside/around your RV. Do you want to just protect the...

  • Will Pest Prevention MouseBlocker Device Handle 50'x30' Garage For 2007 Newmar Dutch Star RV?
    Barry, the 360x # MB64FR covers about 1,000 sq. ft. in open space, so your RV garage about 1,500 sq. ft. would be best served with two units - one at each end. That way the ultrasonic sound fully blankets the space, since it doesn’t penetrate through the RV itself or walls. You could even add a plug-in # MB34FR inside the Dutch Star for inside-the-coach protection. Do you mainly want to protect the garage space, or the motorhome interior as well?
