Works great!
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.

Wow these things have a strong scent!!! Money!
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!

Perhaps My Mice Are Different
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?

This Works Great
This stuff really works.. we used in kennel building to keep mice out of the dog food and went all winter with no mice.... No nasty odors

Not working for me
I heard that these typically work pretty well, but they are not working for me. I put three of them under the hood of my car in various, safe spots, and it is not keeping the rodents out. I live in a rural area so field rodents can be an issue, especially if nearby neighbors are not being proactive with keeping them out of sheds and barns. After cleaning under the hood I used 3 pouches. Checked a few days later and it was evident the rodents came back.

Mouse repelent
Strong peppermint scent. Keeps mice at bay but need to be diligent about replacing when scent dullls overall seems to do trick.

All natural
Smells pleasant not over bearing. Strength of smell does not last long period's to our sense of smell, however we have seen no further evidence of mice despite this. Further time will tell, at has been about 3 weeks now, happy with this product so far.

Finally, a deterrent that doesn't smell like toxic chemicals, great for enclosed storage.
I bought these to toss into my storage bins and the corners of my garage/shed where I’ve seen droppings in the past. I wanted something that wouldn't risk harming my dog if he found it, and I absolutely refuse to use mothballs because of the lingering smell. The Scent (Peppermint & Cinnamon): When they say "Extra-Strength," they mean it. When you first open the bag, the scent is intense, mostly peppermint with a spicy cinnamon kick. • Pros: It actually smells pleasant, almost like a strong holiday candle. It makes the area smell clean rather than dusty. • Cons: Do not place these directly in your living room or bedroom. The scent is potent enough to be overwhelming in a high-traffic area. These are best for attics, basements, RVs, or boat covers. Effectiveness: I placed these in "problem corners" about a month ago. Since then, I haven't seen new droppings in those specific areas. • Important Usage Note: These are repellents, not traps. If you already have a mouse family living in your walls, this won't force them out. I used these after clearing out the area to prevent them from coming back, and for that purpose, they work great. Longevity: The scent stays strong for about 3-4 weeks, then starts to fade. You need to give the pouch a squeeze or shake every now and then to "reactivate" the oils. Verdict: If you want to protect a classic car, an RV, or Christmas decoration bins during the off-season, these are perfect. They work as a barrier and smell infinitely better than traditional poisons or mothballs.

This is surely the worst purchase I made in my life. This product is useless as rats march royally over the pouches. Sheer waste of money.
