    Hi everyone. I've searched and not found any details on this, or on YouTube. I live in an area with a lot of rodents, and I've caught 3 mice in the cab of my car (little buggers). So I have purchased the Loraffe Rodent Repeller on Amazon, and it has great reviews. It needs to be hooked up to the battery, but the battery is in the trunk area on the right rear. I did some searching, and I'm wondering if this rodent repeller can be wired to the 12V fuse box in the engine compartment, because the engine area is where it needs to do the beeping and flashing the lights. Does anyone have any details on this, particularly an install video, for me to put this in?

    While I'm asking....do you recommend installing one of these, two of these, or installing them in the rear, too? I've read that rodents can be a real problem with Prius vehicles due to the soy based wire wrappings, and since I have a known mouse problem I better take it seriously since I just moved into this neighborhood 2 months ago and have already had 3 mice caught. Others on other forums recommended doing an anti-rust treatment for the undercarriage or the engine, which makes those soy wires less tasty. Can you give me your thoughts and experience? Thanks! I appreciate all comments!

    i've never read of them working, but i hope you have success!

    there is a 12v jump point in the fuse box. i don't have a video, but you can certainly wire it in there.

    What is the current draw on this device? It is pretty easy to run down the little 12V battery.

    If the car is parked outside at night attracting nocturnal rodent predators may help. Get a cat. Put up an owl box. Spraying predator urine around the car might deter some rodents.

    Or apply this Honda Rodent Tape:

    A cat left unattended overnight may attract cat hunters.:)

    Meshing the egress points will be much more effective, basically 100%. Any hardware store will have galvanized steel anti-rodent screen, with 1/4” mesh spacing. Install securely with sheet metal screws, they’re not getting in.

    first priority would be the opening on the firewall, the cabin air inlet. You’ll need to remove wipers and metal cowl for this.

    When you can get to it, especially if they persist, there’s a couple of cabin exhaust vents, at the rear corners, below hatch floor. For this it’s best to remove rear bumper, create two mesh boxes.

    one more worthwhile, and easy: mesh the end of the engine air intake snorkel.

    The tactics you’re considering are only worthwhile for engine bay and underbody wiring.
