Grandpa Gus’s Extra-Strength Mouse Repellent Pouches, Peppermint & Cinnamon Oil, Natural Rodent Deterrent Control for Garage, RV, Car, Basement, Attic, Storage, 1.75 Oz (Pack of 10)

Yes. I've placed an order twice as I live in an apartment. This has made a huge difference in m space as you don't know how other's live and mice just like to come inside when it's cold. I've been here for over a year now and I just this past January noticed a mouse traveling from the tenant next door to my bedroom closet. I keep no clutter and entire space is kept very clean. So, I'm sure that helps as well. We had the pest control for our community to come out and he used traps. I'm afraid of mice so having a trap was not for me. I placed this in my bedroom closet, and it has deterred the mouse. He tried coming back one time and immediately vacated! I keep the floors vacuumed and I place cotton balls inside with peppermint and cinnamon oil (a little goes a long way). This helps when I vacuum and it gives off a pleasant scent that I enjoy but mice despise. So, the combination of the pouches and my upkeep has made this a win win! I'll continue to purchase as these pouches are a great maintenance for my space.

My sister and I have both used these, and it really drives them away. I have very rarely seen these any mice at all! I make sure I keep extra of these handy, for the garage or the basement. Not to mention, they smell nice!

Sorry, Grandpa Gus - perhaps Connecticut mice are different, but here's my story. I have a 2004 Toyota RAV4 that sits outside under the trees and is used infrequently during the summer. Both last summer and this summer, I could hear one or two mice in the headliner of the car when I got in, running around over my head. When I banged on the headliner, they would move around. This year, I suddenly had lots of weird electrical issues, and the Toyota dealer had to drop the headliner to get at the source of the problem. Five wires had their insulation chewed off and had shorted. There were four mouse nests in the headliner and two in the inside rear quarter panel. Apparently, this is not the first time the Toyota guys have seen the issue, and they did not have a solution to the problem. The Toyota guys had my car for two days to do the repairs (dropping the headliner is a major job) and it cost me $760. Obviously, I had a real incentive to solve this problem, so I turned to Amazon and read reviews of mouse repellents. At the time, Grandpa Gus had 7 reviews that were all 5-star, so I purchased a package of 4 pouches, putting 1 pouch under the front seat and 1 pouch on top of the battery, which is a dry area near the cabin air filter and frequently a point of entry for mice. Two days later, I drove the car to Home Depot and was disappointed to hear a mouse in the headliner when I got back to my car in the parking lot. I theorized that the Grandpa Gus odor was not getting from the interior of the car into the headliner, so I dropped the overhead light in the front of the headliner and shoved a Grandpa Gus into the headliner itself.....and then placed another order on Amazon for four more pouches. That enclosed headliner space is a pretty small volume for its own pouch, so I was optimistic. Unfortunately, the mouse continued to run around in the headliner for the next three days, after which I removed the Grandpa Gus pouch from the headliner and put two small, perforated plastic bags filled with cotton balls that had been injected with "Majestic Pure Peppermint Essential Oil" that I also purchased on Amazon - that product had the second highest rating on Amazon as a mouse repellent. The Grandpa Gus pouches were still on top of my battery and under the seat. For the next three days, I banged on the headliner and was pleased that there were no mice running around over my head. On the third day, I opened the back door and was surprised to see a tiny mouse inside the car! I tried to quickly throw the trunk liner out the rear door but the mouse ran under the seat – right at the pouch of Grandpa Gus. I put two mouse traps inside the car and proceeded to capture that tiny mouse along with 3 of his/her siblings – no mama or papa mice; just small baby mice, like the one in the photo. The peppermint scent apparently had driven the small mice out of the headliner into the interior of the car, where Grandpa Gus proved to be totally ineffective. I feel bad writing a negative review because the Grandpa Gus folks followed up both of my orders with a nice e-mail with suggestions for pouch placement and an offer for me to call them anytime if I had a problem. Perhaps Grandpa Gus works for large mice (mama and papa size), but it certainly didn’t work for the baby mice in my car. I really didn't see any reason to call them for help. Basically, there were at least 4 small mice living inside the interior of a 2004 Toyota RAV4, which is a fairly small car, along with a pouch of Grandpa Gus. I will remove the Grandpa Gus from under the seat and on top of the battery and replace it with perforated plastic bags of cotton balls that had been injected with "Majestic Pure Peppermint Essential Oil." On a positive note, the odor from the Grandpa Gus pouches is fine to live with. Unfortunately, the mice seem to have the same favorable opinion of the Grandpa Gus odor. Update 7/6/17 - I revised my rating from 1-star to 4-star based solely on excellent customer support. After I posted my initial review, I was contacted by Nick at Grandpa Gus, concerned that their product did not work in my situation. We exchanged a couple of e-mails so that Nick could better understand my situation. Without my asking, Nick offered to refund the cost for my two purchases, and he promptly took care of that refund. Because I wrote in my initial review that the peppermint scent has been working in my car, Nick also offered to send me, free of charge, a Grandpa Gus spray product ("Grandpa Gus's Natural Mouse Rodent Repellent - Peppermint Oil for Mice & Rat Control") because it includes peppermint oil as one of its ingredients. Although that product arrived today, it will be a few weeks before I can give this new product a fair test, and I don't know whether or not it will work in my situation. HOWEVER, regardless of whether or not it works, I increased my rating to a 4-star review to reflect the excellent customer support Nick provided. This is probably the first time in my life that I have ever been contacted by a supplier, offering to refund my money without my asking and to supply a replacement product for free, simply because they want satisfied customers. I initially purchased the product because of good Amazon reviews, so it obviously works well for some people. If you combine that success for most customers with their superior customer support, how can you go wrong by giving this product a try?

Had mice in my stored vehicle last year, no signs of them after using these things this year! A friend recommended them I took his advice and seemed to work quite well. Very pleased!

Easy and clean to use

We live on a country acreage property and had rodent problems forever. Tried everything under the sun but finally found this product and have. solved the problem. Thank you so much, I give it a A Plus review.

Seems to help somewhat, not a full answer to the mice who winter over in the garage

So I had problems with mice last year in my truck. Grand Gus stopped that pretty fast. This year it’s friggin rats in my kitchen. It’s been a veery cold rough winter here in Maine. I’m battling one very persistent rat in my kitchen. Minimal food in my kitchen, I think it’s just looking for a warm, dry space. I have ultrasonics, just annoys them. Thus far adding grandpas has stopped the little bugger. Check back in a week. This stuff is a bit strong smelling but it works! I had the nightmare scenario of a mouse family or families in my vehicle. In the engine compartment, and in the headliner. The headliner. Having little mouse dance parties over my head while I was driving. Squeaking and chewing on things they had no business chewing. I was willing to use lethal traps, but preferred not to, as there are mice babies in this population, and I’d rather not kill those. I’d gotten battery powered infrasonic sound emitters before getting grandpas pouches, and they sort of worked, but they weren’t enough. So, I’m not a huge fan of peppermint smelling things, but apparently neither are mice, so I’ll deal. I think the cinnamon makes the difference. Worth the reasonable price ! Would buy again.
