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

I purchased this product a time ago. It's working well. I use the strobe mode and I also utilize the test mode as well. It seems to work. I use a combination of other things too.

They really work. I tell everyone about this product because in Tucson lots of cars get the wires chewed by the pack rats

Operates as advertised. No mice in motorcycle yet. We have this hanging next to bike in bike barn. It's summer, so time will tell. Keeping fingers crossed.Also using mole deterant spikes as combo.

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.

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.

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.
