Rodent Repellent Battery Operated Ultrasonic Mouse Repeller for Car Engines Squirrel Pest Repeller Under Hood Rat Repellent Mice Deterrent for House Garage Attic Indoor 1 Pack

Easy set up . Waiting to see results.

I have two of the repellants in one cubbard, two in a tool shed , and two under the hood of an automobile. They seem to work—no rat-poop found after installing them. Recommend them highly!

My only issue is the battery life is a bit short. Was hoping it would last longer than advertised.

This product didn’t work in my camper. They ate right through the spray foam , where this thing was located. Took 10 mice out of there with those snap traps. I feel bad, I took out the whole family.

I bought this to deter squirrels from doing any further damage to my engine wiring and it has done a fantastic job at keeping them away.I have a 2017 Ford Focus hatchback that is parked in the driveway by an oak tree that produces tons of acorns, attracting all sorts of critters. Around February/March of this year, I noticed my car was driving a bit differently, seeming to struggle. I looked under the hood and there was a bunch of leaves & sticks packed into the engine and some wires had been chewed a little. I cleaned out the mess and put some moth balls & rodent repellent spray.When I checked a few weeks later, the nest was bigger and the engine harness had been chewed to pieces. It was too late to avoid damage but I needed. I bought this device, cleaned out all the mess & put this device under the hood.About 5 months later, I’m finally able to get my car taken care of (out of pocket) so I checked under the hood today and it looks the same as it did in April - no new nests, so sign of critters aside from some cobwebs. I wish I would’ve gotten this at the first sight of damage to avoid all of this, but lesson learned.When the batteries start getting low, the device will emit a noise every 10 seconds or so and seems to do so for quite a while so you likely won’t miss hearing it. It takes 2 C batteries which last several months.I found this device to be extremely effective and after I repair and sell my car, I will be using it by the front porch where the chipmunks like to hang out. Definitely recommend it for keeping squirrels away.

I have six of these that I put in the engine compartments of my two cars each night, along with two bright LED lights per car. I bought them because mice were urinating on the engines each night.Overall, this solution has been effective. It's rare now for there to be signs of overnight mouse activity. At first, I was also putting peppermint essential oil in the engine compartments (this is also an effective mouse deterrent) but I've stopped doing that and the ultrasound + light is enough. I think the ultrasound is more important that the LEDs because I initially tried to deter the mice with LED lights only, and this was not effective. However, it was only when I started putting 2-3 of these ultrasound units in each car (2 in my Corolla; 3 in my larger 4Runner) that the mice went away. One unit per car was not enough.I would have given this product five stars because it has been an effective part of my mouse deterrent. But the manufacturer really cheaped out on the switches. Every now and then, they become very hard to operate and you have to switch them on and off any times (using considerable finger force) in order for them to become usable again.

We were having issues of mice finding their way into our cars. It was awful. We purchased these, and within a week, the mice were gone. We sat these products on the console between the driver’s and front passengers seat, and switched them on in the evening. We are still using them as a deterrent, and the batteries last for about two-three months. We are so very grateful to have found these.

The battery seem to last longer than advertised. I did notice a decrease in the noise of the critters, and it seems to have scared them away.

Ratty so far has ignored the spray that is supposed to put them off, chewed up the foam, made a hole through the cement before it was dry, pushed wire wool out of the way, eaten the skirting board round the piece of metal blocking his previous holes, and seems to be immune to rat poison, so I was really excited about this. I set it up outside the latest hole Ratty had made. It was great, flashing lights in different colours and no Ratty or so I thought. Three days later I came downstairs only to discover Ratty had pushed Repeller out of the way and was wandering along a ledge on the wall. When he saw me he leapt down a vent near the ceiling, he then dragged himself up and peered at me over the edge with a big grin on his face.

Completely ineffective against squirrels and burns through batteries.

The product just has not worked you actually need time to give it chance to work but £48 you would think that there would not be any problems however that was not the case please look into sorting out a refund

Product does not work and is surprisingly small. Squirrel is still in the loft, doing whatever he likes and sits right next to the repellent.
