Loraffe Under Hood Rodent Repellent for Car Engines, 12V 24V Ultrasonic Mouse Deterrent with LED Strobe Lights – Mice and Rat Repeller for Truck, RV, Vehicle Engine Protection, Pack of 2

Not working for Indian rodents. Tried in 2 cars from 2 different locations. Only flash lights and no sound. Rodents foot marks observed regularly.

Over four years ago when we purchased this WONDERFUL device. We had some serious wire damage from rodents, mice and/or squirrels and we found this wonderful little device on Amazon. We have had this device for over four years now and it is still working just as strong as it was on day one. Our son actually called us today (4 years after we put this in our vehicle ) and told us how he had thousands of dollars worth of wire damage done to his vehicle because of squirrels chewing on the wires and he didn’t know what to do after he got his car out of the shop because he knew it would just happen again. We immediately told him about this wonderful device that we had purchased four years ago and he immediately ordered two of them. I knew immediately I had to get on here and give this review and give this wonderful piece of equipment the credit that it deserves because as I said, I have had this wonderful little device for OVER “4 YEARS” now and I haven't had another single ounce of problem from any rodents or squirrels or any kind of critters chewing on any wires. Noting; I have all kinds of critters running all over my property at any given time. As a matter of fact, I don’t even see a cat walking on our vehicle anymore or any evidence there of like cat tracks. I don’t know if this is supposed to repel cats, but I used to have cat prints going up and down my windshield all the time, but I don’t even have that anymore. This is a wonderful little device and it’s very simple to install, and I highly recommend it 100% to anyone that has to park their vehicle outside. It is a very small investment that can save you thousands of dollars of damage in the future. For some of the bad reviews that I’ve read maybe they did not have it grounded properly. It’s very simple to install, but you do have to install the positive and you have to make sure that it’s grounded so if you do not have it grounded properly it’s not gonna work properly so just be sure that you have it connected to the positive and you have it properly grounded and then you are good to go. You can tell it’s working, you will see the flashing white lights and red light , etc. I can still see my lot four years later still shining strong!! I have not touched mine for four years and it’s working perfectly still and I’m sure has saved me thousands of dollars in damage and protected my vehicle 100%. As far as durability, it is very durable it has held up very well for the past four years and looks just like it did on day one. And it is also working just as well as it was working on day one which is perfectly. if I could give this item 100 + stars I would because it’s worth every penny that I paid for it and more.

Had a rat problem. Rats were gettin in under hood of cars and eating the wire insulation. My mechanic told me about these so I tried them. I haven’t had any more problems with rats under the hood anymore. Very easy to install.

They arrived as scheduled. Easy to install. Seem to work just fine. Good directions. However... I experimented with several different locations under my hood. The conclusion is that they need to be placed where the rats tend to make their nest under my hood; in my case it was directly above the strut, so I placed the device where it was directly within the line of sight of the nest area. At first, I tried to use just one device per car by placing the device in the center of the engine compartment, but that was not directly within the line of sight on either side of the car strut area, so it failed to deter the rats. By using both devices in one car (one on each side of the engine compartment within line of sight of the two strut tops), I was able to annoy the rats enough that they went somewhere else to build a nest. Nowhere in the provided documentation was I able to find this info; I had to experiment to discover this strategy. Recommend that the seller update their documentation.

I don't write many reviews. I'm just another real person, buying stuff of Amazon. So the fact that I was moved to leave a review of this product, should tell you something! I'll try to keep it short. about 6-7 months ago, I noticed empty shells, droppings and other rodent evidence under my hood. I cleaned it up, and in the process discovered the little guys worked their way under the engine cover in my 2.5 year old Volvo and started chewing on the wiring. Boy that could have been expensive if I didn't catch it when I did! Luckily they had only chewed through harness tape. I'm handy with cars so I repaired the wiring and decided something needed to be done. And so I embarked on a quest to keep mice out of m engine bay. The thing I learned is, everything works and doesn't work. Most of it is pseudo-science, not any solid prinicples of the "right way" to keep mice away. So here you are reading yet another review. All I can tell you is what worked for me. I tried: Water with peppermint oil/exctract: I soaked the engine bay, put pure drops of the stuff into the foam engine cover, sprayed around the wheel wells and under the car. Smells nice, supposed to offend the mice. Maybe for a day. They came right back. If it does work, it's not for long at all. Serious offense - Rodent Mouse repellent and spice: I purchased a commerical mixed rodent repellent here, peppermint and cinnamon based. Not content to just win a battle, I spiked the stuff with capcisium. That'll teach 'em! I put a little too much maybe, I had to spray the stuff on in a ventilated area and wear a mask, otherwise just the fumes burned my lungs. Clearly that should repel a mouse? NOPE they were right back the next day and every night after. And the mixed smelled awful as it burned off the hot parts underhood after a drive. Sorry but I gotta do what I gotta do - I really hit the end of my rope, and it was me or the mice had to go! I had a feeling the mouse that already lives under the hood won't go so easy as keeping new ones out. So I set up an Owltra electric trap, and put it under the hood overnight each night. Over a week or so, I killed 5 mice. So this kinda work, but it didn't stop them from coming in and pooping everywhere before they found the trap. My car sits outside so I felt like I caught enough of the mice to prove it wasn't just a matter of evicting a "tenant" to solve this problem. And so we come to these things. As ever, there is not any good science behind "ultrasound" bothering mice. Not anything that comes out of a cheap little speaker outside of a lab anyways. Flashy lights seem to be about the same. But I was determined I needed to try everything for myself. Since these come in a 2 pack I installed 2 of them. For me I want a permanent solution so the battery powered devices won't do. These were easy to wire (for me though I am experienced in such things). I put them in places that were convenient but also tried to cover multiple angles and both sides of the underhood area. What can I say...other than since cleaning everything up one more time, and installing these, no a single evidence of rodent activity. It was an every night occurrence before! Now a month in and still clean. I'm analytical, I can't figure why this pseudo-science stuff works. I can only theorize: the underhood area is small, you don't have to cover a whole room, so the flashy lights especially, they must be sufficiently jarring. If you watch these they have a rather random pattern, and that may be key to scaring off the mice. Although you can't hear the "ultrasound" noise, these do make a faint *click* noise when they go through that cycle, and that may be a good thing too. I call it the "mouse disco" and apparently the mice don't like to dance. Five stars on this, it solved a difficult problem. Only criticism I can offer is the wiring, while the "hot" positive side is fused as it should be to prevent short cicuits, the fuse should be as close to the connection as possible, but it's not on this product. So you have 6 inches or so of hot wire that, if it ever rubs through or gets pinched, is going to cause a problem. Hopefully just melt some plastic and whatnot, rather than start a fire under your hood! So be careful routing the wires with this. Otherwise it's a great product, and for me, it WORKS.

I was hoping this would fix it since it seems so cutting edge with a flashing strobe and ultrasonic sound but nothing changed. I had rats eating cables before and even more cables being eaten with more activity after I install these. They work correctly where every minute or two it flashes a little strobe LED and you can kind of hear the ultrasonic sound a little bit And I placed it as good as I could to cover as much area in the engine bay but you can’t cover everything because once the hood shut that light is only going in maybe 20% of the engine compartment. So it was wishful thinking but what a waste of money. The only thing I found that actually works is buying peppermint essential oils in the little Bottles for home air infuser’s at Walmart soaking Q-tips in a bottle with it and then throwing them around the inside of the car and in the engine compartment. I’ve been told that rodents do not like the smell of peppermint and it lasts about 2 to 3 weeks before the smell dissipates, and the rats are back so it’s a solution but you have to constantly do it and the essential oils are about 5 dollars a bottle. I’ve tried traps and they work for a while but then they figure out that their friends are dying or being caught and then they avoid the peanut butter or any other tasty smelly treat that I have tried to put on there. Anyone have any ideas how to keep rats out of your car they actually get into the interior somehow in a 2012 Dodge grand Caravan and a 2000 Suzuki grand Vitara. I used to have a Chevy sonic and they came in through an air duct and made a little nest in the cabin air filter that they annihilated so I don’t know what car manufacturer is doing, but they sure are keeping them rodent proof .
