Our Grandpa Gus’s Mouse Rodent Repellent review

I live in an apartment building whose basement is prone to mice and rat infestations. Sadly, these creatures sometimes crawl up and enter different houses. Pest control agents have visited the building a few times before, but their efforts have not eradicated the problem. Therefore, it does not come as a surprise that we have tried and tested several brands of rodent repellents, some of which have failed us. I spotted a mouse in my kitchen about four weeks ago, so I bought Grandpa Gus’s Mouse Rodent Repellent because it sounded promising.

I used the rodent repellent for slightly over four weeks, so I will share my experience so far. I will focus on the product’s scent, thickness, ease of use, value for money, and effectiveness. The views expressed here are solely based on my experience, so they made me different from yours.

Scent (8.6/10)

The first time I used Grandpa Gus’s Mouse Rodent Repellent, I instantly loved its pleasant scent. It was unlike all the other products I had used before. I had tried the chemical-based products before had such a foul smell that I once slept in a hotel room because I could not tolerate them. The scent of the peppermint and cinnamon oils give the product a delightful odor that is not overpowering or irritating to the eyes. I instantly fell in love and made my second order without due consideration of other factors.

I loved that the pleasant smell infiltrated the entire house within no time, so it worked as an air freshener for me. Smelling the spray gave me confidence that the rodents would smell it too and run away.

Thickness (6.6/10)

Although I fell in love with the scent of the product, I hated its thickness. Grandpa Gus’s Mouse Rodent Repellent was too dense for my liking. The package came with two 8 oz bottles of the product, each promising about 1240 sprays. However, each spray was a hustle for me. The spray nozzle did not release the product in a fine mist that could achieve good coverage. I had to place the nozzle close to the target area for the formulation to reach the intended location.

After several sprays, the spray nozzle on the first bottle got blocked. When I tried using it, the product spilled on my hands. I had to open it up and try to unclog it. I then tried to spray again after shaking the bottle to ensure that the ingredients were well mixed. The nozzle still failed to work as effectively as I would have desired. This made the application of the product a bit hectic. Eventually, I decided to change the spray nozzle and use one from a different product. This seemed to help with the situation. The second bottle worked fine with its original spray nozzle.

Ease of Use (9.0/10)

Grandpa Gus’s Mouse Rodent Repellent did very well when it came to ease of use. I did not experience any problem with usage. The spray nozzle was very easy to use. The sprayer looked like that of perfume as opposed to the nozzles with a handle that requires pressing. Using it was as easy as using your favorite scent after taking a shower. It did not need much effort, but I noticed that it was fragile. If you are not careful, you can easily destroy the sprayer.

I did not appreciate the lack of instructions regarding how much of the product to use. While I understand that this product can be used in many different areas, there should have been a guideline on how many sprays to use for a given site. I am still not sure whether I over-sprayed my little house or not.

Effectiveness (8.2/10)

I was very conflicted about the score to give. Remember I earlier mentioned that I ordered a second pack of two based on my love for the scent? Well, I will tell you that I did not use the third and fourth bottles. They are still lying around the house. Initially, I felt that the product was beneficial. After religiously using it each day of the week, I did not spot any mouse or rat in my apartment, which made me very happy. The only downside at the time was not knowing how much of the spray I had used to get that level of effectiveness.

I used the two 8 oz bottles within four weeks, which I felt was a bit much because of the size of the apartment. Since the product had done such a splendid job and I felt like I had misused the two bottles, I decided to take a break. I thought that what I had done was enough to keep all rodents out of my apartment for a very long time. I was also getting tired of the peppermint scent.

About a week later, I came across mice droppings in my apartment, and I was appalled. I was on the lookout for a mouse but did not find any. However, the droppings indicated that there was at least one around my house.

This situation made me question the effectiveness of this product. I decided not to use the repellent again unless I spot a mouse. I also realized that Grandpa Gus’s Mouse Rodent Repellent’s effectiveness was based on constant use, which I was not ready to do. Unless the situation becomes severe, I will not use the two bottles I got from my second order. I am looking at other options for eradicating the mice and other rodents from my house.

Value for Money (7.8/10)

Right now, you already know that I have mixed feelings about this product. I loved the scent very much and enjoyed having it also work as an air freshener in my house. I also loved its ease of use. Using the spray was as simple as using your regular perfume. However, the thickness of the spray was off-putting, and so was the overall effectiveness.

The latter made me feel that the product did not offer much value for money. The value of the product value would have been improved by providing guidance on the amount of spray to use per day. It would also be better if the product worked over a long period, instead of relying on spraying for the rodents to be kept at bay.

Final Verdict 8.0

If the final score were based on ease of use and scent, Grandpa Gus’s Mouse Rodent Repellent would have earned a very high score. However, the score is much lower because I had a significant issue with the spray’s thickness that made it cumbersome to use. I also felt the pinch of having to rely on the product to keep rodents at bay. Frequent replenishing would make the spray very expensive in the long run. After evaluating the pros and cons of Grandpa Gus’s Mouse Rodent Repellent, I gave it an overall score of 8.0/10.
