The answer to rodent problems

The Mouse Blocker Pro is the most advanced rodent deterrent available for your vehicle. It takes everything great about the original Mouse Blocker and makes it even better. The powerful ultrasonic sounds emitted from this unit are now adjustable and now even louder than the original model.

Why chewing rodents are costing car owners big bucks

CTV’s Ross McLaughlin investigates why eco-friendly wiring insulation is enticing rodents into cars.


Did you know?

Rodents are prevalent across North America, and they sometimes hide away inside your car, truck, or RV. 

Once they’re inside, they can chew on electrical wires or make a nest, damaging your car in the process, potentially rendering it inoperable and costing you hundreds, or even thousands, of dollars in repairs.

Protect your property humanely

The Mouse Blocker Pro is 300 times louder than any other unit on the market today and on the highest settings most humans can hear the sounds emitted as will some household pets like cats and dogs. The sounds WILL NOT harm them in any way you will just notice the animals will leave the area the unit is located and if under the hood of your vehicle the sounds for the most part will be contained to the engine compartment anyways.
