PATTLER® Best Car Engine Mouse Deterrent. Car Engine Mouse Deterrent. Mouse Repellent for Cars Connection to 12V. Ultrasonic Pest Repeller to Keep Rodents Out of Cars. Rat Repellent for Car - 1 Unit

Easy to install, seems to work. I got these after 3 separate encounters with rodents eating my wiring harness and taking up residence in my A/C blower. THey seem to work as I am rodent-free now for 6 months

I have a f350 diesel truck. Had constant mice sitting at top of both batteries and mice dropping issue. Purchased 2 of these and used one on truck and other on my Honda accord. Best tool I purchased, followed instructions to clean infected area then hook them to vechile battery. After 4 months no more mice issues anymore since I purchased them. Read and follow instructions then you notice it works. Very real results.

System doesn't work mice made a nest on top of the unit. Not happy. And yes it was on

I can’t speak to if the device works. There is no noise and the light does not flash (or at least I can’t see the light).On line installation instructions do not exist. There is a QR code that takes you to a site and from there are links to YouTube etc that don’t work. With that said, if you are all handy it is easy to figure out. Install at the battery terminal and mount somewhere under your hood (I used double sided tape). What I don’t know if there is a particular direction to point the device.

I recently started working from home and driving my car a lot less. when i popped my hood for regular maintenance, there were acorns all over my car battery where a squirrel or rat was attempting to build a nest. After ordering and connecting this device, i have seen no evidence of pests in my car. It has been connected approximately 3 months. It runs off of my car battery and has not run it down or anything.I live in the woods, so rats and squirrels chewing up wiring harnesses and building nests in vehicles that sit for periods of time is a common issue. I have recommended this product to all my neighbor's for their cars, too.This product saved me the headache of making costly repairs down the road. Thanks!

Easy to set up, rats not showing up anymore. Four cats from neighbors frequent my backyard lately; so, hard to say, maybe a combination of the device and cats, or could be the device alone worked in keeping rats away!

Since installing the unit I have not noticed any sign of mice activity in the vehicle. Would definitely purchase again.

We’ve been having problems with a squirrel or squirrels, chewing up wiring underneath the hood of my kids car. It has to sit in the driveway because there’s no room in the garage. After some expensive repairs, I purchased this item in an attempt to deter these rascals from damaging our property. Today I found a loose wire in the driveway and I thought oh gosh, we have a problem again. Not only did this not deter the squirrels, but it’s the first thing they ate. It ate the wiring the powered this device as well as some other wiring. This thing has only been installed for six days .
