Ultrasonic Rodent Repellent for Car Engine - Battery Powered Under Hood Animal Repeller with Flashing Strobe Light, Keeps Rats and Mice Away from Vehicle, Automobile, Truck, Garage, Attic, Pack of 2

I bought this as a preventative for mice intrusion into my car and truck. I had a mouse problem while living in Virginia now in Nevada. Luckily the mice did not chew on my wiring just started nesting. I installed this on my new car and have not had any signs of mice so far. The lights are a nice feature that gives you a quick visual to see that It’s on and if lights weren’t on, time to replace the batteries. I’m happy with no signs of mice!

My wife's new car started shuddering and making horrible noises last weekend. We took it to the mechanic and were informed that there was a big rodents next behind her engine and they had chewed through 2 of the wires. I immediately bought this double set of sound makers, 1 for each car. When I installed them, the following morning I looked under the hood... and there were new rat droppings on top of both of our engines, and new leaves debris that the rats had pulled back into our engine compartments. I figured... our cars have large engine compartments, with tons of nooks and crannies. We should probably have 1 on each side of our engine compartments for our cars. I bought a 2nd pair of these. So we each have 1 on the left and the right side of our cars engine compartments. It has now been 4 straight days without ANY signs whatsoever of rodents under our hoods. No droppings, no debris, foilage... nothing. We are extremely happy. Yes... it took having to have 2 of these for each of our cars, but that's a small price to pay to not have to deal with it again. The only annoying thing is that the battery compartment is on the BACK of these units. So in 40 days when I go to put in fresh batteries... I'm going to have to cut the zip ties and completely remove the units. Replace the batteries, then re-zip tie them back in. It would be MUCH nicer if these held the batteries towards the front of the unit, so that the backing could stay secured in place when you swap batteries. But it's a minor inconvenience compared to the benefits.

So, based on the mostly positive reviews I decided to give these a try. I even went above and beyond to prepare my car, as I had the engine compartment professionally cleaned to get rid of any trace of prior rodent activity. I placed one of these in the engine compartment using the ties, and the other sits in the cubby near the gear shift. For the first couple of months, I didn’t see any activity. However, one day I am driving and my odometer stops working. Then the check engine light comes on followed by the steering indicator light. And about the same time I lose power steering. Took it to our mechanic and sure enough, rodents had chewed through several wires causing the problem. Fortunately it only cost $270.00 to fix. I say fortunately, because our Toyota Corolla had $2,500.00 in rodent damage about seven years prior. Needless to say, these Ultrasonic Rat Repellants didn’t do jack! 8/23/22 I have an update and in turn, I am raising my rating. So, after they didn't work as described, I decided to try them with the sound on (in Test mode). And guess what? After 3 weeks of parking it in the same spot, they did not eat the wires again. In fact, I see no evidence of them being in the engine compartment since the last episode. I will continue to use them with the sound on. If they didn't work for anyone else in the Ultrasonic mode, then try them with the sound on. It has worked for me so far.

I had a problem with rats building a nest in the engine compartment of my RV built on a Mercedes Diesel Sprinter chassis. I tried everything from professional solutions to various online hacks. Nothing worked until I purchased a pair of these. I placed them in the engine compartment. They immediately worked and after over 6 months there has been no rat problem. I also have a barn with a tractor inside that had the same problem so I purchased another pair and no more rat problem. I recommend this with max stars. I would give it more than 5 stars if I could.

These devices are brilliant. The extra 'siren' button they offer is that extra touch that truly saved my car engine and helped to keep the rodents from entering the kitchen cabinets from behind the stove area - which we can't get to yet to close off entry points. I had found insulation being used as nesting material on top of my car engine, with chewed wires - when we lost power for only a few hours during the winter. The plug in models of rodent chasers I use are great - but when losing power, it only took a few hours for the mice to re-enter the garage and nearly ruin my engine. These battery operated devices did the trick - and thank heavens for them - and their wonderful design giving us the range to using the siren at night (can only hear it when in the garage). We even use them under the bathroom cabinet, and in one of our kitchen cabinets where mice had somehow gotten in from behind the wall. We have them on 24/7, then at night, turn on that extra switch for the random siren - and wow has it worked. 4 weeks and not a single sign of a rodent. It is giving us time to figure out the next steps [and expense] of finding builders and repair folks to find the entry points around both the garage and the house. I highly recommend using these in tandem with the ultra sonic/EMF devices in your outlets, to get them out of the walls. I'll be ordering more to place strategically in other areas for when we lose power - so we don't lose the protection. WONDERFUL products!

Todo ayuda contra los roedores en auto

Yes, finally got around to using this item. Kept vermin and unwanteds out of the vehicle motor whilst car was not in use. So will definitely buy again. 👍

El sonido de test funciona pero no permanece para auyentar las ardillas

Okay it is still flashing away after a few months and seems to be working or the cats have picked up their game. Non intrusive in engine bay and cable tied ( zip tied🇱🇷) to solid panel section.
