About this item

  • EASY TO INSTALL: 12V Powered - MouseBlocker's Simple 2 wire installation under the hood directly to your vehicle's battery. No need to check flashlight batteries to see if they are dead or corroded. Trust your vehicle's battery to constantly provide power to the unit, never leaving you vulnerable to rodents.
  • MULTI-PURPOSE: Protects Cars, Trucks, Motorcycles and Snowmobiles, RV's, Boats and Jetskis, Tractors and farm equipment, ATV's and Dirtbikes, or anywhere there is 12V power available. Safe at under high under-hood temperatures, stable at well below zero Canadian winters and unaffected by moisture and dampness, and only the size of about a deck of playing cards!
  • POWERFUL: Hitting at 85 Decibels in a specific ultrasonic frequency that was chosen because it sounds like a Jack Hammer to rodents. When the unit is placed in the engine area it effectively makes it too uncomfortable for the rodents to nest - therefor deterring them from chewing on costly wiring harnesses, fuel lines, hoses, and computers.
  • ENERGY SAVING: Super efficient! Uses only .1 Watts of Power so it runs for a very long time on your battery without draining it. Feel confident that your expensive investments and toys are protected.
  • PROFESSIONAL GRADE: The MouseBlocker is trusted by hundreds of New Car Dealers, Independent Repair Shops and Auto Parts Retailers throughout North America. Our units work work great for protecting your new vehicle from mouse damage that is not covered by your new car warranty.

Product Description

Mouse Blocker Classic, the worlds first 12V Ultrasonic device.

The Original MouseBlocker Classic

The MouseBlocker classic was the worlds first ultrasonic mouse and rodent deterrent dedicated to 12 Volt applications. This unit is 12Volt power with very minimal power draw releasing and ultrahight frequency noise. This noise sounds like a jackhammer to mice to deter them from nesting inside your vehicle or equipment. This unit can also be ran in remote locations with access to a 12 volt battery. For daily driven cars we recommend our MouseBlocker Pro model and for storage we offer the Plug-In pro and our Mouse Blocker 1000x.

How does it work?

MouseBlocker 12 Volt Under Hood

Rodent protection for trators and equipment

Very minimal battery draw

Built Tough

The Mouse Blocker installs in your engine compartment and is designed to be stable in this harsh environment. Safe at under-high under hood temperatures, stable at well below zero degree winters and unaffected by moisture and dampness associated with exterior operation.

Designed to Protect

Stable in areas of heavy vibrations like tractors and mowers and compact enough (about the size of a deck of playing cards) to hide almost anywhere. Easy to install in anything with a 12Volt battery.

Low Power Draw

The Mouseblocker Classic is perfect for Motorcycles, Snowmobiles, Mowers and farm equipment, ATV’s and Jetskis. Many of our RV dealers use multiple Classics spread out throughout the RV or Camper to protect the space.

Poor QC--can't recommend

Poor QC--can't recommend
I hooked it up to a 12 power supply--it didn't light up. Opened it and saw that the LED actually did light but was bent over and couldn't be seen from outside. I wonder how it earned its QC sticker. I then discovered that the hole in the case for the LED was .2" offset from the LED after I straightened it up. Maybe the LED was deliberately bent over over, but that fix was not good enough to allow any light out of the box. I found a white LED in my junk box that was much brighter at the same current and fit in the hole (with the lens removed). Its forward voltage is higher, so the sound level is now probably a bit lower than the claimed 85db. The drive frequency is about 12 kHz, which is not really ultrasonic, but if it's working, my 76-year-old ears can't hear it.
