I first saw that rats were living their best lives in my garden on a cold night in March. I was making tea when I saw something move quickly along the hedge from the kitchen window. It was too big to be a mouse and too brave to be scared of me walking on the patio. The bird feeder moved back and forth. The top of the compost was open halfway. In the dark, leaves rustled with the quiet, steady sound of an animal that knows exactly where it is going.
I remember telling myself, “You are not going to stay here for the winter.”
I searched the internet for traps and poison that night. Then, by chance, I found an answer that was almost boring in my bathroom cabinet. My garden felt like mine again with just one simple product.
Rats Don’t Care for Your Garden. They Like the Way You Act.
If you stand still in a winter garden for a minute, you’ll see that the silence isn’t real. There is life going on under the shed, under the decking, and behind that pile of old pots. Rats don’t just appear out of thin air. They come together around things we forget, like the birdseed that spills, the trash can that doesn’t quite close, and the warm spot under the compost bin where the wind never reaches.
They aren’t coming into your space just to be mean. It looks like you left them a welcome mat with signs that they can read.
A neighbour told me about the time she found a nest of rats under her kids’ trampoline. She had seen sunflower seeds disappear faster than a bird could eat them. She stopped one afternoon after lifting one corner of the rubber mat. A ball of shredded plastic, leaves, and fabric that is neatly packed in the driest corner. There are little black rice-like droppings everywhere.
Not a lot of scary films. Just quietly and patiently putting together a winter shelter a few meters from her back door.
That’s how rats behave. They test the watch and get closer when they can get food and their shelter stays safe. A tunnel is a small hole in the fence, a hotel is a pile of wood, and a buffet is a leaking trash bag. There are a lot of chances in your garden. They stay there for the winter once they know your place has food and a place to sleep.
If you break either of those rules, your garden will lose its charm. They will choose a different address if you break both.
The Bathroom Item That Makes a Big Difference
This is the twist. A strange oil or a magic spray won’t work to keep rats out of your bathroom. It’s just regular peppermint toothpaste, the kind you probably already have next to your sink.
Rats have a very good sense of smell, and strong menthol smells make them feel bad. They automatically stay away from it, as if the ground itself had turned against them.
When used right, this common paste makes a soft barrier that tells them, “This garden is not for overwintering.”
It’s simple, but it works better if you think about it first. Put small amounts of peppermint toothpaste on important rat highways like the bases of fences, near sheds, under stairs, around compost bins, and near any holes that look suspicious. Look out for protected areas where you’ve seen poop or heard scratching.

Put some toothpaste on old cotton pads or paper towels and stuff them into the gaps or cracks. Do it again every few days when it rains, especially at the start of winter. It feels strange the first time. Then it turns into a yearly tradition.
Let’s be honest: no one really goes around their garden every day looking for rat tracks. We all look once, don’t see anything, and think everything is okay. That’s when they usually show up. This toothpaste trick doesn’t replace good hygiene, but it does add a smell barrier that you can’t always be behind.
It’s inexpensive, safe, and won’t harm pets or wildlife that might eat a dead rat. If you already use peppermint toothpaste, you’re not adding a new chemical to your life. You’re just sending a different message outside with a smell that your bathroom is used to.
There are two worlds in one product: fresh breath on the inside and a doormat on the outside.
What People Do Wrong When They Try to “Fight” Rats
A lot of us make the biggest mistake by going straight for the strong poison without changing anything else. Poison kills some people, but if your garden still has food and cosy spots, another wave will come along the same path. The toothpaste barrier works best when you make small changes that you can handle, like picking up birdseed that has fallen once a week, closing bins all the way, raising wood piles, or keeping them away from the house.
It’s like pushing rats to the point where they decide your place isn’t worth the trouble.
Another common trap is leaving temporary messes that slowly turn into permanent ones (not the metal kind). Broken pots, old cushions, and planters that are covered in a tarp are some examples. We’ve all done this: You say to yourself, “I’ll take care of this on the weekend,” but six months later, it’s still there. In the winter, those corners that people forget about are great places to hide.
Even the best peppermint in the world won’t be enough with that and a steady supply of food. The smell tells them to leave, but the setting tells them to come home.
One pest control worker told me, “Rats don’t care about how clean you are.” They only ask three questions: Is there food? Is there any water? Is there a place to sleep? You need to start saying no.
Quick Guide to Rat-Proofing Your Garden
- Close up the holes: Fill in gaps around pipes, under doors, and along walls with metal mesh or filler. You can also keep toothpaste close by to keep rats away.
- Switch up the menu: Keep pet food inside, use bird feeders that squirrels can’t get into, and once a week, sweep up the extra seeds.
- Get rid of the corners: Get rid of anything that hasn’t moved in a year and move the stacked wood away from the house.
- Lines of entry for targets: Put peppermint toothpaste back along fences, under gates, and near sheds at the start of each cold spell.
- Look for clues: You can find your next minty roadblock by looking for droppings, chewed-up plastic, or narrow paths in the grass.
A Small Ritual That Makes You See Your Garden in a New Way
When you start doing something before the rats move in, your garden stops feeling like a war zone. You stop fighting with nature and start working with it. The toothpaste trick has a strange effect that makes you feel more grounded. You go outside on a cold morning, see the minty dots on the fence, and know you’ve made your point without hurting anything.
It means, “Yes, there are animals, but not under my deck, in my compost, or next to my kitchen wall.”

Questions and Answers
- Does peppermint toothpaste work better than other kinds? Strong menthol or peppermint toothpaste works best because the strong smell keeps rats away. Toothpastes that are mild or fruity don’t work as well.
- Is it safe for kids and pets to use peppermint toothpaste? When used in small amounts on surfaces, it’s much safer than poison. Don’t smear it where pets or small children could lick a lot of it, and refresh it quietly in cracks and corners.
- How often should I put it back in the garden? Every few days when it’s wet or after a lot of rain, and then once a week after that when the smell pattern is set. Pay attention to the beginning of winter, when rats are looking for a place to live.
- Can I use toothpaste alone to get rid of rats? No, it’s not a magic rubber; it’s a deterrent. For real, long-lasting results, do things like cleaning up food sources, sealing holes, and getting rid of clutter.
