2 Pcs Under Hood Rodent Repeller with Strobe Light & 3 Power Supply Methods, Professional Ultrasonic Mouse Repellent Rat Squirrel Deterrent for 12V Cars Trucks RV Engine Bay Warehouse Attic

Stopped all of the rodent activity. Worked great.

I've had several occurrences of squirrels chewing through my vehicles' electrical harnesses (yes....PLURAL). I've tried rodent-repellent sprays, repellent electrical tape, live traps....you name it. This device seems to be having some luck in deterring the miserable little critters. It required a different connector to fit on to my truck battery, but after a quick trip to the hardware store, the device was relatively easy to install. My son says he can hear it when he walks by it. I can't. Older ears will be oblivious to the high-pitched signal. The device only engages when the vehicle is not running....or so it says. I can't confirm or deny this. There's also a blinking light that it has which is not noticeable until you lift the hood of the vehicle. I imagine it's pretty irritating to the little furry monsters.

I installed easy to do. Not sure if it works but have no rodent problems when camping. May be no rodents anyway. Small investment so I am good with it.

These are great deterrents. We had two vehicles get wires chewed by rats and squirrels. In all fairness I think the squirrels were just trying to stay warm near the engine but, do make a big mess. In winter 2021 my wife’s Jeep was in the garage, $1200 in damage as it required the CPU be replaced along with a couple of the wiring harnesses. In winter 2022 my truck was outside and luckily only has had wires chewed up and discovered before major damage. They did manage to kill the signal from a knock sensor so I will have to get that fixed at some point. We tried all sorts of deterrents over a couple of years dealing with this. Bought these in September ‘24. It is almost February’25 and no more rat droppings, urine, chewed wires or acorn shells.

Beware...It seems these don't work! As you can see in the photo, I put two Rodent Repellers, turned on and plugged into power, under the hood of my Prius and a rat made a nest on top of one of them. The lights flashed when I lifted the hood.I only gave it a star at all so I could give a review.

I put one of these where the squirrels like to hang out in the engine bay of my car. It seems to be working or at least helping in addition to the other things I've done to keep them out.

Seems to work well so far. Would buy again if needed. Shipped quickly and reasonably priced....

Wish I had found these sooner. Bought as a fix after a $900. repair. Darn packrats were making a home under the hood within just two days of it sitting. Since installing this device I’ve been packrat free. I just have to set reminders to change the batteries, as I chose not to connect to the car battery. Like the instal options with this thing.
