Mighty Mint Peppermint Oil Rodent Repellent Spray for Vehicles – Natural Mouse & Rat Control for Car Engines, RVs, Trucks & Boats – Plant-Based, Extra-Strong Formula – 16 oz

The smell is pleasant ( I love peppermint) and the application is easy, I do wear gloves and spray under the hood, car, inner fender (the covers above the wheels) once a week. I live in a city of RATS (NYC) and I do street parking so this product works extremely well. I no longer see droppings under my hood and on my battery anymore! Now I apply the product monthly during the summer and will be back to spraying weekly when winter comes. I give this product a 10/10

Update: the company reached out to me and gave me a refund. Pleasantly surprised. The company didn’t ask me to edit my review.Original Review: I really wanted this to work. I followed the instructions carefully and was diligent about spraying the engine bay regularly, but it made no difference at all. Rodents still got in. At the end of the day, I paid $40 for what amounts to peppermint oil and water. No noticeable deterrent effect whatsoever. Total waste of money. If you're hoping this will protect your vehicle, learn from my mistake—don't fall for it like I did.

Easy to apply. So far, we've been able to hold off another rat/mouse attack on our car's wires. Only issue was that one bottle busted open during shipment. I suspect the Amazon delivery driver is more upset than I am.

I’ve been using Mighty Mint Peppermint Oil Rodent Repellent around my home and garage to keep mice at bay, and it genuinely helps reduce their presence. The strong, fresh peppermint scent is quite overwhelming for rodents and seems to deter them from entering treated areas. I use cotton balls soaked in the oil and place them near entry points and places where I’ve noticed droppings. While the scent needs refreshing every few days to maintain effectiveness, it’s a safe, non-toxic alternative to chemical repellents, and I appreciate how it leaves my space smelling clean and minty. For mild to moderate rodent issues, this peppermint oil repellent is a great natural option to try.

I decided to try this as I have lots of mice in my car. It worked for the first round. I was ecstatic! And I sprayed the engine and under the car and in the trunk and on the floor. pretty much the entire car. And it smells pretty good. then, 2 days later, they were back. I sprayed and sprayed. Then I sprayed a day later and then 2 days after that. But they were/are determined. I refuse to use the lethal traps. So I will continue my quest for humane to get rid of the mice. P.S. I have 5 cats. And they are just not interested in the mice in the car. They're fine with the mice in the barn and chicken coops - but not in the car.

WOW, this really works. Have many pieces of equipment that is stored both in a shed and outside. Little critters (mice) loved to make homes in the equipment. Since using this product "mickey" has gone on to different pastures saving my equipment. Works great on all pieces of equipment.

What the....?Was really hoping this would work. Desperately need a solution for mice who have been getting into my car engines. Opened the container and had to pump the nozzle like 200 times to get the repellant to spray. Once it finally sprayed, the nozzle went to pieces. I had the repellent all over my hands... when to wash my hands and came back to a mess- leaked all over the place.I think there were a couple of other reviews that had something similar happen. Took a chance hoping it was just a one-off situation.Hope this stuff works, my garage will probably smell like peppermint for weeks. I'll try to update my review once I go buy another spray bottle that works.

Had evidence of rodent activity eating away at the insulation under the hood on a not so old car. I was very upset and bought this and an electronic rodent deterrent. I put the gadget in the car, and I sprayed this all over my engine bay. It smells good. I did this every day while leaving my hood up, with a floodlight shining on the engine. What I did not expect was the rodent hit the bait box my pest control company placed on the side of the garage. The mouse then must have gone back and forth until the bait ended his poor little life. He ended up dead deep in my wheel well and I had to put up with the nasty decomposition until it ended. I am happy with this spray and it doesn't leave any kind of mess or oily residue. My garage spelled great while I tackled my rodent issue.
