Hi, I’m Richy!

I’m a proud husband who spent years working in the pest-control industry, and my wife and I now live beside a farm where we’ve dealt with our fair share of mice. Each year I test and rank top household pest repellents. Enjoy!

My Research Outcome & Overview

Getting the right product that worked at a consistent rate proved to be difficult as many of the products had little to no effect. Having a child and pets at home, safety quickly became important in my rankings. To be honest, it’s extremely challenging and overwhelming in such an urgent time where you just want them gone. Most of these products take time to really see results making the testing a drawn out process.

This in-depth guide can be used to take my learnings and apply them. Yes, this is more than the average homeowner is willing to go through, but with my background, I had fun with it! I also created this comparison chart that summarizes all of my research. I update this post whenever there’s a new product to test to ensure that all of the information below is recent and accurate.

Scientifically Testing Mouse Repellents

My checklist and scoring framework

My key components and checklist ((Quality + Effectiveness + Cost + Safety + Smell) / 5).

  1. Test The Leading Mice Repellents - Firstly, I wanted to ensure that I tested all of the leading mice repellents on the market that I could find. I chose the following brands: Grandpa Gus’s, RodentRX, Sofyre, FreshCab, Earthkind, Bell+Howell, Everfield, Mighty Mint, and Tomcat.
  2. Sample Size - My house is 2,048 sq ft and we had rodent sign in multiple areas making there a few "test zones" to start. The main hot spots were the kitchen and bedrooms, but the unfinished basement also had heavy sign.
  3. Factors Compared - I rated each repellent based on the following factors: effectiveness, smell, safety, cost, and quality.
  4. Rating System - I then rated each course on each category with a simple 1-5 rating system (1 = not great, 5 = amazing).
  5. Choosing A Winner - Lastly, I added up all the points for each repellent and gave them a final score to choose a winner!

Testing Environment & Layout

I also needed to test the effectiveness of each repellent to see if it worked for removing the mice. Finding the right test environment was the hardest part. Here’s how I did it:

  1. I found the most active areas and started with the products were really easy to use (ultrasonic & tablets).
  2. I then gave each one enough time to prove results which was typically a week or more depending if there were any early indicators. There were three main locations I was able to test in. Once I found the one that worked best, I spread to the entire house at the end to confirm.
  3. I determined effectiveness by assessing how many new droppings would appear, (I did see a mouse run across our kitchen counter during this period, but story for another time). Based on the size of the droppings, I had determined both mice and rats were in the home which was a little more intimidating if I’m being honest.

Mouse Repellent Types

Why Electronic Worked The Best

Pros of Electronic Repellent

Noticed results in the first week - It was relatively immediate results having tested these pretty heavy in the kitchen (where the most sign was). We went from fresh sign to minimal new sign. I think if I would have expanded to more outlets, it would have been faster too.

Safety - After researching for days, the electronic solutions were the easiest to use, and 100% child and pet friendly. There is a little thought that needs to go into how many rooms to put these into, but nothing that seems too out of the ordinary. While the pouches also claim to be pet and kid friendly, they also all include cautions to keep out of reach of pets and children, which was contradicting to me.

Smell - This one is often overlooked, but important. Electronic devices had no smell. I had mixed feelings between other pouch solutions, some overwhelming, some bad, and one smelling like an air freshener. I like that the electronic device did not have any smell.

Less Expensive - The cost is extremely reasonable when you think about how much some of these products are. Pest control I was quoted over $2,100 including an ongoing fee. I’ll focus on per unit cost in relation to overall coverage vs total cost as the volume was different on each one.

The mouse stays alive - These are made to deter mice and rats (rodents) vs kill. This avoids any mess and having a rodent rot in a wall for example. If you haven’t smelt this before, consider yourself lucky!

Cons of Electronic Repellents

Out of stock issues - During peak seasons I’ve struggled to get my hands on more for friends, family, and clients. What I’ve found to work best is to stock up when available to avoid this. I’m sure this will improve over time, but something to watch out for.

Outside usage - While these work great indoors and places like garages and sheds, they don’t hold up long in the exposed elements of nature (rain, wind, sun etc...).

Replacement - While these are made well, and all of mine are still working, including the one in my toolshed that is exposed to hot summers and cold winters, it may add small cost if these need to be replaced.

⭐ Overall Rating ️
My ABSOLUTE favorite this year! The RodentRX ultrasonic repeller checked all of the boxes luckily making it a pretty easy #1 choice. To my knowledge, it’s new this year. It completely cleared the area in the test phase, and then moving to the entire house it stopped the sign and sounds pointing at the mice moving out which was my main goal. They also the safest and easiest to use.

❤️ What I love ️
A lot of the repellents I tried seem to have little to no effect. I remember some of the pouches having mouse sign literally right next to it a day after setting it down. Not the case here. There were no droppings anywhere near the device, and the safety for my pets and kids was key.

🙈 What could be better
I’ve been using these for a while now, and coming up on peak season of 2026, this sounds minor, but is annoying that they run out of stock. Originally I only ordered 3 to test them out and when I later returned to purchase more they were temporarily out of stock, but just something to keep an eye out as they seem to have problems keeping up with demand. The other thing is usage outside. While not a concern for me, you may be stuck with getting a different solution for that.

📄 Description
"Stop mice from invading your home, garage, car, truck or RV with a simple and easy plug and play solution. A hassle-free pest control barrier for any home."

☁️ Quality & Packaging
The packaging was simple and clean, and the device itself seemed to be high quality as well. I was actually surprised how well put together this felt.

📊 Multiple Options:
Depending on the size space you have or are going to be using these for, they had multiple quantities to purchase, and price discounts for ordering more.

📏 Instruction for use:
Very easy to follow instructions and usage recommendations. They also go over a lot more of the benefits and research they have done on their end. Pretty cool to see it live in action.

Runner up

Sofyre Rodent Repellent Pouches
Check reviews
4.2/5
What I love:
  • Real peppermint & cinnamon oils, not a fragrance dressed up to look like them
  • No traps, no poison, no kill
  • Safe around kids & pets when used as directed
  • Clean packaging design
What could be better:
  1. Customers report being auto-enrolled in a subscription they didn’t sign up for
  2. Some buyers report never receiving the order they paid for
  3. Trailed RodentRX on effectiveness in every test zone I ran
  4. Pouches lose potency, so reorders every ~30 days add up
  5. Heavy smell in small rooms after a week or two
  6. No coverage behind walls or inside cabinets

⭐ Overall Rating
Sofyre is my runner-up, and I want to be precise about what that means. It trailed RodentRX in every test zone I ran. The pouches knocked down sign in two of three zones; droppings kept reappearing in the third, where the device cleared it. The peppermint-cinnamon scent also goes heavy in a small room after a week, and two pouches every 30 days adds up fast across a full mouse season. Sofyre earned the runner-up slot because it at least uses real peppermint and cinnamon oils instead of a fragrance with rodent imagery on the front. That is the entire compliment.

The bigger problem is how Sofyre sells what it sells. When I went to read their Trustpilot reviews, I kept running into the same complaint: customers auto-enrolled in a monthly subscription they never knowingly signed up for. Several mention checking the one-time purchase option at checkout and still being placed on recurring billing. A separate cluster describes orders that were charged for and never shipped. Whether either pattern hits your order is a coin flip, and that uncertainty is the problem. A plant-based, pet-safe brand sells on trust; a checkout that surprises customers undercuts it.

If you try Sofyre anyway, double-check your cart and screenshot the order page so you have evidence if a recurring charge shows up later. If you came to this review tired of paying for products that don’t solve the problem and surprise you on the bill, the RodentRX outlet device is the cleaner answer. One purchase, no autoship, no email thread to cancel.

❤️ What I love
Real peppermint and cinnamon oils, not a fragrance dressed up to look like them. Clean packaging. The “Safe around kids, pets & livestock” positioning is the right lane, and Sofyre frames it correctly. That is where the credit ends.

🙈 What could be better
Three problems. First, the billing: an auto-enrollment subscription customers didn’t ask for undercuts a “you can trust us with your home” brand outright, and the “paid for and never received” cluster sits in the same bucket. Second, performance: Sofyre trailed RodentRX in every test zone, including its best-shot one. Third, pouches are a consumable, you reorder every 30 days, and the per-season math catches up fast. RodentRX solves all three in one move.

4.1/5
What I love:
  • Keeps rodents alive
  • Essential oils
  • Can use outside
  • Easy usage material
  • Safe for kids if used as directed
What could be better:
  1. Not as effective as I would have liked
  2. Smell wasn’t as nice in my opinion
  3. Bulky and heavy, needs certain storage environments

⭐ Overall Rating
These mouse repellent pouches are a decent alternative, however, I found that needing more, not being as child and pet friendly, and having to replace every 30 days were some minor inconviniences that has me preferring the electronic device. I do think these can see similar results to our top pick, and I may even test them more in the future. All natural ingredients make for a huge bonus as well.

❤️ What I love
While Easy to use, these did not seem as effective as the RodentRX in terms of results as in the time I spent testing them. The overall quality and design seems to be solid. I would recommend using this as a replacement if out of stock issues are causing problems.

🙈 What could be better
Not a ton of advantage of going this route in my opinion. Based on the testing and results I mapped, there’s other packet / pouch options to help solve your mouse or rat problems.

4.1/5
What I love:
  • Easy to use
  • Safe (if used appropriately)
  • Pre-scented pouches
  • All natural ingredients
What could be better:
  1. Effectiveness - Not very effective
  2. Cheaply made for quality
  3. Bad reviews online
  4. Little more expensive

⭐ Overall Rating
Another option if you’re struggling to get pouches to work, or dealing with out of stock issues. While I didn’t have as much luck with this one, it may work for others. The pouches themselves are very nice, but very similar to Earthkind and seem to almost be the exact same.

❤️ What I love ️
Clean design and packaging and has the same pouch concept as the others which I like the most. The ingredients are also all natural. They don’t specifically call out pet and child friendly like the other ones do.

🙈 What could be better
They don’t specifically call out being pet and child friendly which was a concern for me and my use-case situation. The design could be altered to be it’s own product vs very similar to the others.

4.0/5
What I love:
  • High quality and easy to use
  • Keeps mice alive
  • Natural ingredients
  • Well packaged
  • Smell was pleasant
What could be better:
  1. Most expensive cost per pouch
  2. Not very effective
  3. Similar to other pouches
  4. Strange oil feel on pouches

⭐ Overall Rating
Quality tablets that may just need to be spread out closer together to which would probably leave better results. I do think these can see similar results to our top pick, and I may even test them more in the future. All natural ingredients make for a huge bonus as well.

❤️ What I love
Similar thoughts as other pouches, but not as effective in terms of results as RodentRX. The overall quality and design seems to be solid. I would recommend using this as a replacement if out of stock issues are causing problems. Price is also very cheap per unit.

🙈 What could be better
Not a ton of advantage of going this route in my opinion. You need to use a lot more of them, and they are messy. Based on the testing and results I mapped, there’s other packet / pouch options to help solve your mouse or rat problems.
