It sounds like a social media craze, but the “teaspoon trick” is based on an extremely effective, cheap and organic principle. When people talk about using a teaspoon to repel ants, they usually think of cinnamon (followed by two effective alternatives: ground coffee or baking soda).

Here’s an explanation of how this minimalist method works and why it’s so ingenious!

The Teaspoon Trick: Cinnamon Against Ants
Ants are not pests in the traditional sense of the word, but they can become a nuisance on the terrace or in flower beds. They navigate almost exclusively using their extremely sensitive sense of smell. And that’s exactly where a teaspoon comes in.

Here’s how it works:
Take a teaspoon of real cinnamon powder from the spice rack.

Sprinkle the powder directly on the anthill or around the nest on the patio.

Effect: Cinnamon is a nightmare for ants. The intense scent completely masks their scent trails (pheromones). The ants become disoriented, can no longer communicate with each other and immediately avoid the area. They move away voluntarily without having to be killed.

Alternative 2: A teaspoon of coffee grounds
If you don’t want to give up cinnamon, use dried coffee grounds.

Application: Place a teaspoon of used, well-dried coffee grounds in the cracks of the patio boards or on the anthill.

Effect: Here too, the strong smell is a deterrent. Ants also don’t like the texture on their feet. Bonus: Coffee grounds are also an excellent fertilizer for your garden plants.

Alternative 3: A Teaspoon of Baking Soda (If Repellent Isn’t Enough)

If ants are already undermining your patio stones and the subtle scent trick isn’t enough, try using baking soda.

Application: Mix one teaspoon of baking soda with one teaspoon of powdered sugar and sprinkle it around.

Effect: The powdered sugar acts as bait. When ants ingest the baking soda, the pH in their stomachs changes, which is fatal to the insects. Note: This is a radical method if simple repelling doesn’t work.

Why this method is so clever:

Non-toxic for pets and children: Unlike chemical ant baits from the hardware store, cinnamon and coffee grounds can be safely sprinkled where children play or dogs run.

Costs next to nothing: A teaspoon from the kitchen drawer is often enough to redirect an active ant trail.

Protects the garden: Chemicals often kill beneficial soil organisms too – cinnamon and coffee do not.

Important note for the patio: Once you have successfully repelled the ants, wipe the area with a little vinegar water. This will permanently remove any remaining traces of the ant pheromones!
