Does Peppermint Spray Really Get Rid of Mice? I Tried It to Find Out

Cooler weather always brings a spike in visits from rodents. Mice, cute as they may be, chew through cords, gnaw into bags of food and leave droppings in cupboards and on counters and floors. If you have a hoard of big-eared bothers encroaching on your space, I found the best, completely humane and non-toxic fix for mice infestation. 

Last year when the problem hit critical mass, I tried several strategies to curb the mouse march into my Brooklyn apartment, including cutting off any supply of food and setting several mouse traps. In the end, the mouse deterrent that worked the best was also the safest and easiest to deploy. A $20 peppermint spray has kept my abode mouse-free for well over a year. 

Here are the various methods I used for getting rid of mice, ranked from worst to first.

The best and worst ways to get rid of mice

5. Tomcat Bait Station

Poison bait traps represented my third attempt. These devices lure mice in with an enticing smell and offer a block of green, edible bait that's laced with poison. These didn't work at all. I never found so much as a nibble taken from the bait block. And the more I thought about it, these posed a far crueler fate for my unwanted intruders than even snap traps. They also mean dead and decaying mice scattered about your home.

4. Starvation

My first approach was to starve the mice out by sealing up food as best I could and overcleaning the kitchen after every trip. It worked to a degree and I noticed fewer encounters, but my kitchen doubles as a busy meal-kit testing site; try as I might to keep food bits and odors from lingering for more than a few minutes, there's only so much one can do.

• Cost: None.
• Grade: C-plus.

3. Humane traps

Next, I tried humane traps at the puppy-eyed request of my partner, a dyed-in-the-wool pacifist. These contraptions work by luring mice into the hull with food; when they enter, their weight triggers a door, trapping them inside. Then, it's on you to release the live mice, preferably far away so that they don't come back -- mice have a famously good sense of smell and direction -- and hope they become someone else's problem.

I set two, and they worked as advertised. I caught a mouse every few nights but it did little to dissuade others from following in their footsteps. Plus, having to relocate a mouse five blocks away every other morning got old fast.

• Cost: $10 (two-pack) on Amazon.
• Grade: B-minus.

2. Classic snap traps

Snap traps were the most efficient at stopping the parade of hungry freeloaders. Unlike the trapdoor traps, these mousetraps do kill the mice but they do so with merciful efficiency. The snap traps worked well and I caught more mice than I can count, but still more came. And these devices posed a danger to my curious terrier, so they could only really be used safely up high on the counter. 

• Cost: $9 (6-pack) on Amazon.
• Grade: B.

1. Mighty Mint peppermint spray

Having exhausted most of my options short of an expensive appointment with an exterminator, I resorted to a 16-ounce bottle of peppermint spray for $20 on Amazon. (It's also available at Target for $10.)

As directed, I sprayed the white peppermint solution near my kitchen baseboards, on the counter behind my toaster oven and in the crevice behind my wall oven. I reapplied the spray every couple of days. You can also use this spray in basements, attics, the engine of your car or any other spots you might not want rodents hanging out.

The peppermint smell was noticeable for the first few hours, but I found it pleasant. The spray went on clear, and there was no damage to the wood floors or marble countertops where I applied it.

Two weeks later (as of when I'm writing this) and I've seen no droppings or signs of mice at all -- the first time I can say that in months. To be sure it's working, I left two baited snap traps to gauge whether or not mice have been coming around. Neither one has been triggered. 

• Cost: $19 on Amazon.
• Grade: A.

Is peppermint rodent spray safe to use around pets and children?

Mighty Mint peppermint spray is made from natural ingredients and is safe to use around dogs and children. But you'll want to avoid getting in or near your eyes since peppermint oil can cause burning. It also contains soap, so it's not safe to ingest.
