I'm a proud father to my beautiful daughter, and work as an exterminator here in southern Wisconsin. Each year I test and rank top household mouse repellents. Enjoy!
Testing line-up
This year had a pretty solid #1 as you'll see below. I haven't seen these in the past to test so assuming they are new this year - seriously, incredible.
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 become 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.
My key components and checklist ((Quality + Effectiveness + Cost + Safety + Smell) / 5).
Methodical testing using my test criteria and ranking formula.
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:
Test space: Basement (This was one of the three controlled test area's)
One of the main things I wanted to figure out is what style of repellent worked best. Throughout the process there were general themes that formed with similar outcomes depending on what style repellent it was. There's a few things I prioritized in this research:
To make a good decision and ensure I was doing what was best for my home, I used my research to create an extensive pro's and con's list for each type of repellent. Shares below:
I started with a bunch of overall research from websites, blogs, and large retailers (a few tested products not pictured).
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 cabinets, it would have been faster too.
Safety - They typically have all natural ingredients and easy instructions to follow to make sure it's pet and child friendly. There is a little thought that needs to go into it, but nothing that seems too out of the ordinary. Majority also say right on the packaging that they are pet and child friendly.
Smell - This one is often overlooked, but important. The smell was immediately pleasant opening the packages, although overwhelming. I had originally questioned if it would be too overwhelming, but ended up not being an issue.
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.
Natural Ingredients - Majority of these are made with all natural ingredients causing no concern for chemicals or messes.
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!
Snapshot once most of the products arrived for testing.
Out of stock issues - During peak seasons I've struggled to maintain stock as they typically last 30 days. What I've found to work best is go for the subscriptions or stock up to avoid having to change brands. 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 - The packets and pouches typically last for 30 days which seems short, but makes sense in reality, and something that I haven't minded being on a subscription plan reminding me when to change them.
The "even more robust" testing framework
Safety - These units are relatively safe outside of the electrical component. Usually come in an oval shape large enough to avoid a choking hazard.
Ease of use - By far the easiest to use as all you do is either plug it in or plug it in and push a button.
Cost effective - They are typically really cheap ($20-$50) and don't have ongoing costs outside of electricity and if the units need to be replaced from not working.
Keeps the mice alive - Acting as a deterrent, the rodents are just supposed too move out of the area due to the high-frequency sound waves that humans aren't supposed to be able to hear.
Effectiveness - I've tested these even outside of this research with little to no luck on 90% of them. There was one that seemed to help a little bit, but even then there's better solutions.
Quality - All of these are made extremely cheap as they only serve one purpose. It's pretty noticeable on the packaging and plastic quality right away.
Considering all of my important factors for mouse repellents (listed above), I created this comparison chart. Everything here can be found on Amazon or the respective products website.
To recap, I guess I was expecting a little better results across the board vs just a couple of products working. The main area I wanted to focus on was actually solving my mouse and rat problem in the house. After that it was safety for my pets and kid along with the smell. While a lot of the packets are surprisingly similar, for whatever reason RodentRX performed a lot better - guessing something with ingredients or packaging. Obviously this is one use-case, so do with this information as you please.
I was able to place the packets in the majority of places I needed to. I did this by discovering sign and literally placing the packet right over top of it, or anticipating where they may be traveling. This worked well. The core areas for this were the kitchen and our master bedroom which both locations ended up with no new sign when actively keeping up with them. It's been months since any new sign has appeared and will continue to use them replacing every 30 days. As we head into colder temperatures I'll keep testing and update here if anything else is discovered.
I also enjoy seeing what other products come to market, so check back to see if this changes. If you know of a product not tested here that's worked for you, reach out to let me know!
Being a homeowner is fun, but I know the feeling all too well the first time you find out you have unwanted visitors. Good luck to you, I hope I was able to help!
