P3 International Under Hood Animal Repeller

Living in a more rural area, we get mice in pretty much every outside vehicle, lawnmower and shed. Things get much worse in the winter. They have caused me to sell a 4 wheeler because they wouldn't stay out of the clutch housing and it was an hour job cleaning them up every time I wanted to use it.Imagine my horror when my mechanic told me a half-dozen mice jumped out of my 3 year old car when they started working under the hood. I tried a lot of different things to get rid of the mice from the car (mostly scent based stuff), but so far this is the only thing that has worked. This is amazing and worth the money.It worked so well, I got a 2nd one for our grill on the deck. Yes, in the winter, the grill would get infested with mice and meant a long cleanup job every time we wanted to use it. After putting this in there, no more mice. Ever. Again.Here are some things I noticed about this Repeller. Battery life is very good. Batteries would last at least 6 months and maybe more.However, when it got really cold, like below 10 F, it would turn off and I'd have to turn it back on manually.It does make audible noise. When my car hood is closed it is slightly audible sometimes. It doesn't hurt your ears when it's out in the open though, but it would probably be annoying if you had to listen to it all the time. Luckily I only use them in the Winter and am not near for the most part.I have a fat, lazy, non-mouse catching cat and a dog. Neither of them notice it. There are no signs of distress or anything unusual when they are around these Repellers. They may hear it, but it doesn't seem to bug them.I'm going to purchase one or two more for some other areas that mice seem to love - like the garden shed. Excellent product!

This, in combination with a spray, 100% solved my field mice problem chewing through wires in my van.I live in the country and field mice are all over the place. I purchased a Ram Promaster, which I converted to a camper about 3 and a half years ago. I have it parked in my driveway near a creek that runs along my property. It was brand new and came with those "upgraded, environmentally-friendly" wiring harnesses that are made out of soy - you know, the ones that mice think are food. Well, I use the van once every couple months, so there are intervals where it just sits. Didn't take long before the field mice found shelter in my engine bay and ate through some wiring harnesses. $800 fix.I bought two of these, secured them to scrap wood and attached magnets to the wood (to make them easily removable). Placed one in on the underside of the hood and the other near the engine bay underside the van. I made a DIY spray of the following: 70% vinegar/30% water. A few drops of liquid detergent, 1/2 tsp white pepper, 2 droplets of garlic oil, 2 droplets of rosemary oil, and 2 droplets of peppermint oil. This combo is pretty close to what you'll find in those "repellent sprays", but by making it yourself will spend about 1/20th of the price. I spray liberally around the van about 1x per month or after a heavy rain.These two remedies combined have worked flawlessly. All of my neighbors said that there was no way to solve for it unless I moved the van offsite or I kept a half-starving outdoor cat near the van at all times. lolI replace the batteries on these 2x a year - Fall & Spring. They might go longer, but that's the routine I've set up and it works.PS- I know this works, because I've had to share this remedy with 2 other people in my neighborhood who had similar problems (since the mice found nothing they wanted on my property!). They've had zero issues since too.

seems to do the job in new locations, although not well if mice have already left scents/pee etc. I've had good success if able to clean surfaces really well before counting on the beeper.

Does not work for me. Before installing in my vehicle (to prevent Squirrels eating/chewing my wiring up, I took it to a friends house whose wife feeds the squirrels peanuts. I acivated the Repeller & set it up about 3-4 feet from the peanut feeder. After about an hour of watching the squirrels totally ignore the repeller it became obvious that the sound was in no way deterring the squirrels.The LED light would blink about every 12-13 sec. & the device appeared to be working as described.. I really need something that really works --the squirrels are eating the wiring on 2 of my cars the have soy coated wiring. Help!!!!

8/25/17 No change: no rodents under the hood for 3 years now.9/2/16 No change, no rodents. Just changed the battery today.9/19/15 The car has remained parked under the carport, used only about once a week, which leaves plenty of time for rodent inhabitation of the area between the headers and their heat shields or the covered area below the windshield (the places previously inhabited). There have been NONE. The repeller remains in the glove box, facing upwards. The batteries seem to last between 10 and 11 months.12/26/14 There have been no indications of mice in the engine compartment/dashboard area since installing this device. The car remains in the carport at all times is is not in use.10/12/14 We live in a rural area, surrounded by forest. One car is parked under a carport and we have had problems with chipmunks, which I solved with hardware cloth blocking their entrances but mice are too small.Unable to find a place in the crowded engine compartment, and being pressed for time before we left on a 4-day trip, I placed the device in the glove box, aimed up at the dashboard areas. The next day we left in another vehicle, moving this one into the garage which I heavily set with traps. When we returned there was nothing in the traps.
