Rodent Repellent for Cars Battery Operated Ultrasonic Mice and Rat Deterrent with LED Flashlights, Wireless Under Hood Animal Repeller Pest Control Device for RV, Truck, and Vehicle Engine Protection

We purchased the Loraffe Pack of 2 Under Hood Animal Repeller Battery Operated Rodent Repellent Ultrasonic Rat Strobe Light Mouse Deterrent for Car Engine Garage Attic Warehouse Indoor Pest Control, Vehicle Protection as we had a 2006 Honda Civic Hybrid (just traded in on a 2021 Subaru Crosstrek) and also a 2016 Honda Pilot. Mice were getting up in the hood and above the hood insulator pad of both the Pilot and the Civic, and building a nest in the blower fan housing (above the cabin filter) of the Civic. WE had tried EVERYTHING, mainly pillow batting soaked in Peppermint Oil, but once the oil evaporated/dispersed, they came right back! We're trying the Loraffe Under Hood Animal Repeller Battery Operated Rodent Repellent Ultrasonic devices as it was getting expensive to keep replacing the hood insulator assemblies. Very easy to mount in to the Pilot and the new Subaru; instead of using the ties included, I used heavy duty exterior grade Velcro stuck to the back of the devices and placed the other Velcro side on a firm plastic area that was easy to access when the hood was open. It seems that the mice were getting into the engine compartment and then climbing up the firewall to access the hood insulator. As a precautionary measure, I then used some other wire ties and attached a short length of aluminum decorative type chain that I had to the device's mounting holes on one end in the event that the Velcro fails and the device comes loose and drops. We shall see how these devices work before replacing the hood insulator on my Pilot (the danged mice stripped the fibers out of the insulator on the Pilot and had carried it over to the Civic when we had it!! Don't want to take any chances with a new car in the carport! Update4/21/2021 after 2 weeks using the devices in 2 cars:. Picture shown is a BEFORE picture of area underneath the engine cover on a 2016 Honda Pilot. I'd forgotten to check under the engine cover that snaps on to posts above the engine. I had to order another engine cover assembly due to an overly enthusiastic mechanic and to mice chewing the 4 rubber grommets that slip over the posts on engine. When the new engine cover arrived, I took the old one off and there was no sign what-so-ever of any mouse activity under the engine cover, nor in the hood insulator yet! I also have used an aluminum adhesive HVAC tape on the hood insulator (placed on the upside between insulator and the metal hood of the vehicle and placed the battery powered ultrasonics device, along with the 'promotional' 12V device sent by the company along the back firewall where the mice were crawling up into the hood area. Same placement on our new Subaru. I check every morning when I turn the devices off for the day (turn them on at sunset). So far, no mice and I'm very happy with the units!

We live in the country, so mice are a given. We have cats and a dog, so we don't want to use any kind of poison since our cats have gotten ahold of a couple of mice. If the mice are poisoned and the cat eat them, it would probably be too late for vet care before we realized what happened. Of course we take all the preventative steps we can like not leaving any pet or people food out, putting out pet safe mice deterrent, etc. There are baited snap traps all over the attic, basement, closets, etc. but mice would still sneak into the house. Even our pest control guy said that without poison baiting, it would be a constant battle since mice can get into a home through the teeniest openings and a house in a place where they have a lot of natural predators is a spot mice will seek out for safety. We live across from a nature preserve with several species of predator birds such as eagles and hawks as well as coyotes, foxes, and such. Before ordering, we had no idea if these would work or not. Based on online reviews and pest control blogs and websites, it's a toss-up as to whether or not electronic pest control actually works. These and a couple other electronic gadgets like this have been installed and on 24/7 throughout our house for about a month now, and since then the number of mice seen has gone from one (or heaven forbid, two) a week to zero. None. Nada. None in the traps, none caught by our cats and used as hacky sacks or worse brought to us in the middle of the night as a present. The ONLY thing that has changed is the addition of these electronic repellers. Our cats might be disappointed at the reduction in play toys, but we are not and neither is our pest control guy. When we set these up, he wasn't able to tell us if they'd work or not, but even he is impressed that after four/five weeks of having these, there has been a major reduction in mice even though it's freezing outside and the mouse population should have gone up inside as mice seek shelter from the weather. These units are easy to operate, and we set a reminder on the calendar to change out the batteries every five to six weeks. Our pets are not bothered by the lights or the frequency of noises put out through the speakers. They are small enough to be put almost anywhere, and are not intrusive in the least. So far they have been a massive help in our fight against Mickey trying to shack up rent free.

I keep catching mice under the hood despite the proximity the Loraffe ZN-511 Under Hood Rodent Repellent. The brand new batteries are fresh in the device. I tested it and it indicated that it was functional. Update: I've increased the rating on this device. The last time I caught mice in the engine compartment was on Dec 19, 2025. It is now Feb 25, 2026. Between these dates, no mice were caught. So the repellent seems to be making a difference--or something else changed. Last year I caught 29 mice while my truck was in storage. I was not using the ultrasonic repellent then.

Maybe a hard winter is coming because this is the worst year for mice in vehicles at our ranch, we've ever had. I received 1 unit that wasn't working, Email for the company bounced. Contacted the seller who responded quickly, was helpful, and replaced the defective unit really fast. they seem to be working well in the vehicles where mice was the problem. Under the hood of a pickup where packrats were a problem building a nest overnight, I placed one in the cab, and two under the hood. The packrats were not fazed. I've cleared 5 nests out in 5 days. Some mice had gotten in the cab of the truck and they seem to be gone. In this vehicle I've added some PAM spray with powdered hot cayenne which should deter the packrats, it didn't. I tried it loose and it wasn't enough of a deterrence. In two other SUV vehicles, mice had moved in quickly. I combined two units in the cab, front and rear, and one under the hood. I combined this with a large Tomcat tin trap that will hold a LOT of mice. Over 4 days, I collected 10 mice in one vehicle and only two were found alive. In the other SUV, we caught 6 over 4 days. I used Tomcat attractant gel in these traps. To remove live mice, I shake the tar out of the container and daze them. Then I remove and dispatch them. This is the best and most successful method we've had with this problem. It took this combination to make any headway with the problem. Imo, these traps should cost about $10-$11 as you really do need to use more than one. I just strategically place them under the hood and remove them to the inside when driving any of the vehicles. Our air intakes have hardware cloth over them before the air filter to keep the mice out. I give this product 5 stars since it does seem to work on the chipmunks now. It does appear to work well on mice and chipmunks. You have to be a little patient to clear them out, imo. Being battery operated is a real plus and I can see IF I mounted it properly, you could still change the batteries without removal. The ones inside the cabs didn't shut off when driving, so I just shut them off, then turn them back on when I park. The Vendor/company, I now give them 5 Stars. I contacted them and they responded quickly and well. The only success I had with Packrats was to set rat traps and I cleared out a nest of 4. Since clearing out the mice, they haven't come back. This was the 1st time in our years here, that packrats showed up here. If you have serious mice problem, consider adding the Tomcat Tin Cat traps and use the Tomcat gel to clear them from the inside of the cab. I'm using 20 of these devicess overall. The batteries are lasting and they're working. 7/9/20 Update- since my major problem was NOT chipmunks as it had been in the past, but a new one- packrats, I upgraded my rating to 5 stars to be fair to the vendor and removed the negative language concerning chipmunks.

After repeatedly finding evidence of rodents or some other animals in my car’s engine compartment, I looked for something to repel them, and found this. Powered by C batteries, it alternates between bright flashing lights and ultrasound to create an environment said to repel such critters. I like the concept, but found the device nearly impossible to install in the engine compartment of my Acura. The only place I could put it was to attach it to part of the support structure for the car battery. I’ve been using it less than a week, and it seems effective. There has been no trace of any animals living in my engine compartment since I installed the device , and also sprayed the engine too with a rodent repellent. Time will tell. The batteries are said to last a little over 60 days. To replace the batteries I will need to remove the device, then reinstall it. That will be every bit as difficult as the initial installation. I imagine the installation could be much easier in many different cars — but that’s not the case here.

The alarm cycle through lights, silent alarm & non- audible alarm. I have bought several of these items. Some of the boxes I could hear the alarm, some others I could not, with or without the test button on. I dont mind hearing the alarm as long as it repels the rodent which is a squirrel. I had to have 3 of these boxes in my 2011 Ford Escape in order for it to be effective to repel the squirrel. I strongly recommend the unit that uses a C battery as it has a 67 day expiration, whereas the 3 AAA one is every 30 days. So you go through more batteries for the 30 day one. Make sure you set a reminder calendar. I also use Moth balls with this setup. Trial and error, initially I used 1 device- with natural products- the squirrel got me... I then added a 2nd alarm with natural products- squirrel got me again... so I added 1 more alarm, have not had an issue thus far. The ppl below me also got hit- they have 2 alarms on each of their vehicles. So its best to have multiple alarms so they cycle in opposite to each other.

Easy to use. I have one under hood, one on passenger side of front seat and one on floor of rear seat. These along with two no-kill mouse traps to discourage the critters. So far they appear to help. Time will tell. The seller is great…I had a question and was answered promptly in detail. Customer support is commendable! ADD on to review. After 3 weeks of use I’m catching a mouse a day…Thinking the mice get used to the noise and flashing lights…if that’s the case the devices are useless. I have the device in front of the trap and they are walking right past the lights and into trap. So not sure where to go from here!

Purchased as a preventative as opposed to getting rid of rodents (no current infestation). I am using inside my travel trailer which is stored outside in a RV storage facility (covered but not indoors). If I have no infestation in the future months I will presume the units are working. They function as advertised and they come with instructions which is sometimes a rarity on Amazon products. Battery installation is simple and advertised battery life is 65 days which is very good IMHO. UPDATE: Just bought two more for my truck. So far, no sign of rodents in our travel trailer. Units are functioning well. Adding to my truck and another to my RV. Raised review from 4 star to 5 star. Update Jun 7-21, one of the units test button stopped working. Unit worked, just not the test mode. Emailed customer service and the unit was replaced. Customer communication and service has been stellar!
