Wyatt was the first to discover the chipmunks hiding out in the engine compartment of our truck. At first I found his antics funny, but they weren’t enough to keep the rodents from coming back.
Then I discovered the pests were actually nesting in the insulation, tearing up the hood liner.
Knowing that mice and other rodents can cause serious damage by chewing through hoses and wiring, the fun and games were over! After evicting a half dozen of the little vermin, I was determined to find a solution for keeping mice and rodents away from our engine. Coincidentally, a neighbor stopped while I was tracking down the last little rascal. She told me about an expensive repair bill she recently had for damaged automotive wiring, and showed me the MouseBlocker she had installed under her hood.
Install Mouseblocker to Prevent Engine Damage by Rodents
The MouseBlocker is a 12v ultrasonic mouse deterrent. Designed to keep mice away from your engine or any area you wish to protect, the MouseBlocker emits a high frequency audible tone in 15 second intervals. The small device runs off your vehicle’s battery and draws only as much power as an LED clock. The manufacturer assures that this allows the MouseBlocker to run for months at a time without any excessive drain on the battery.
The MouseBlocker is easy to install and can be used to protect your car, truck, or RV from rodent infestation. Install it virtually anywhere with a 12v power supply to keep mice away from automobiles, cargo trailers, or your RV’s storage compartments.
How to Connect MouseBlocker
The MouseBlocker unit can be mounted in your engine compartment with the included self-tapping screws or zip-tie fasteners. The device should be placed in an unobstructed manner that allows for consistent broadcast of the acoustic noise that will not be absorbed by insulating mats.
The MouseBlocker wires connect directly to your battery with the included terminal wire connectors. My only complaint about the MouseBlocker is that the wires attached to the device are too short for use in a large truck like our Dodge Ram 2500. While they may work fine in a smaller vehicle, I just had to extend the length of the wires using extra 14g automotive wiring with a couple butt connectors.
For Installation, you will need:
- MouseBlocker Ultrasonic Mice Deterrent
- Wire Crimper or Pliers
- Crescent Wrench
- Additional Wire & Connectors (optional)
- Black Wire = Positive (+) Battery Terminal
- Brown Wire = Negative (-) Battery Terminal
- Grey Wire = Positive Ignition Source.*
*Optional: No connection = continuous operation. Refer to your vehicle’s service manual for finding a switched ignition source.
Steps to Install MouseBlocker:
1. Determine mounting location for device.
2. If necessary, measure and attach required length of additional wiring.
3. Attach terminal connectors to wires.
4. Attach wires to battery terminals.
5. Mount MouseBlocker and secure wires.
6. (Optional) Connect switched ignition source.
If not connecting the grey wire, your MouseBlocker will simply remain on when the vehicle is in use.
