Under Hood Rodent Repeller Ultrasonic Mouse Repellent Battery Operated Pest Repeller Rat Mice Deterrent Rodent Repellent for Car Engine Garage RV Basement Attic 2 Pack Humane

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.

We used these in our elk camp this year and they worked awesome!Our camp consisted of a wall tent, stove, cots, food and clothing totes, etc. In the past, we would always have mice visit the inside of our tent no matter how well we kept it clean, the longer we stayed, the braver they were! Our pick-ups.... that was another story! I hated coming home with mice nests in the engine compartment that weren't found until months down the road when doing maintenance. People that have had this experience know exactly what I'm talking about....Well forward to this season, we tried these devices in our truck engine compartment and tent and dam did they work well, no sign at all! I only gave the 'value for the money' 3 stars since 1 on the 2 devices was finicky... These will be used anytime I'm camping from now on!FYI- they worked just fine in 15 degrees F at nightThanks for reading!

They seem to be working great for the mice but the chimpmonks still come around but do not stay as long we have coupled it with a live trap for the chipmonks and are removing approx 1/day. Together this is a good solution for us we live in an RV on vacant land near the woods and we have lots of wild life.

The mouse repeller appears to be working. Haven't seen any sign of mice inside the vehicle since I installed them. I did NOT zip tie them down and have both inside the vehicle. I turn them on and off each time instead of letting them turn off automatically when they feel vibration. Figured the batteries would last longer that way and it is super easy to just flick the switch when I get in and out of the car. I have one near the dash, and one on the back seat. I have been using them for a couple of weeks - hopefully the mice won't just get used to them and come back!

After 1k damage by a rat to a '18 Subaru Outback , I carefully read the reviews and gave this product a shot. The first one was super easy to put the batteries into; the second one the screw holding the battery compartment cover was not functional and couldn't get it off. The product does not "cycle off" when the engine turns on or is running, and it also does not repel rats. I popped my hood with the fully device fully functioning, and found him happily chewing my wires again. Bounce dryer sheets and a tin with garlic powder, red pepper flakes and a few drops of eucalyptus oil has worked like a charm.

To hard to figure out how to use it, I wanted an on and off button

Places in my car and after having critters eat through several air filters, I have used the same filter for several months. It appears to repel animals.that can get in your vehicle.

I have installed it properly in engine bay areas of our 4 cars & effectively driven rodents away. The battery lasts 2 months for replacement.

reasonably speed of delivery from the overseas, correct item, works ok to scare mice to stay away at a distance, consumes batteries rather fast

This item didn’t work for me. A rat had gotten into my cars air conditioning duct and was chewing up the air filter. It (or they) were also urinating on top of the engine block. The urinating issue stopped right away but that was probably due to the fact that I started leaving the hood of the car up when I parked it. My car when home is in a garage but the garage walls are made from slots of wood so it remains accessible to rodents. I’ve made two purchases of this item and have three in total. I’ve put them in several places in the car. I thought they might be working because there was fewer signs of rat turd every where but the smell of a rodent in your air duct has gotten worse and just today I had the air filter replaced (for the third time since this problem started about six months ago) and the repair guy said the filter was pretty badly chewed up. About three months ago I had the filter replaced and started using this product then. The increasing smell and the continued destroying of my air filter is very disappointing.
