Grandpa Gus's Mouse Repellent Pouches, Natural Peppermint Oil, 4 Pouches

A little disappointed in this product I used it as directed, and it did not work.

Works great and smells nice haven't seen any rodents in a while

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?

We are having mouse issues and my wife doesn't want to "Hurt" them, so I figured I would give Grandpa Gus's Mouse Repellent Pouches a try. I had my doubts, but I figured, why hurt something if we can just get rid of them. They arrived timely and packaged in a foil coffee like package. Use: I cleaned the area thoroughly with a disinfectant and then with a bleach solution to clear any trace scent from the mice away. I then opened the sealed package, which holds four pouches. I couldn't really smell anything until I got the pouch close to my nose (about 2cm). I placed one on either end of the counter where there had been mouse droppings figuring that mice have more sensitive noses than humans so it might work. Nope, mouse droppings directly in front of the pouches the next morning. I cleaned the area again and put two more pouches on the counter. The next morning there were even more mouse droppings on the counter directly in front of the pouches. I picked up the pouches to clean the counter and smelled them again, there was zero smell eminating from the pouches. So, while my overall experience with them has been terrible, my experience with Grandpa Gus has satisfactory. I contacted them and they immediately issued me a refund. I also purchased the Grandpa Gus's Mouse and Rodent Repellent Spray, which the company said I could use to recharge the pouches, but that has not been successfull either. So a don't buy from me.

I don't know if these work. My handyman recommended them and swears by them. I'm trying to keep mice out of my garage. Ever since a mouse nested in my car air filter I have kept one in the glovebox. Mechanic told me to do that. I just ordered more to replace the others that had worn out. I did find mouse poop on top of one in the garage, so clearly the mice have been there and on top of it. It was an older one, but it still had a fairly strong scent. Maybe two months old. (I know it says replace every month.) So it's hard for me to tell. I guess I will keep using them because it makes me feel better than doing nothing.

Works Great

They work great!!

I have a garage that I store stuff in (all my treasures) deep in the woods behind my house. It is a perfect storage unit accept for one problem! Those pesty little mice. Sadly they made several comfy nests burrowed in some of my boxes destroying some of my personal belongings including Christmas decorations and other sentimental items. It’s war time!! My first attempt to rid the mice was setting up a bunch of mouse traps (that I also ordered off Amazon) the mouse traps worked. They slaughtered 10 mice a day (wow I really had an issue with an entire subdivision of mice) although mice are destructive pests they are also quite cute. It felt so sad to kill all the furry little fellas in a war to protect my stuff. There had to be a better way to make them go bye-bye…. That’s when I decided to give this natural product a try. Keep in mind my initial killing spree was over, so I cleared out the majority of these little woodland creatures…but I don’t feel like constantly setting up traps to keep them away from my stuff, I would rather give them a repellent warning to keep them away yet spare their little lives. I give this product a two thumbs up for keeping my mouse traps clear and saving lives of innocent mice everyday. I also believe the little mice rate this product with 5 stars as they now know this is a prohibited area without getting the death sentence. It’s a win win for everyone including the mice! And it’s not toxic to dogs or small children which is a bonus!
