There’s nothing more frustrating than spotting a trail of ants marching across your kitchen counter.
You clean the area, wipe everything down, and think the problem is solved—only to find another line of tiny visitors the next morning.
Before reaching for a strong chemical spray, there’s a simple household trick you can try: cinnamon.
Its strong aroma is unpleasant to many ants, making cinnamon a popular natural deterrent around potential entry points.
How to Use Cinnamon Against Ants
You don’t need much. Here’s an easy method.
What You’ll Need
- Ground cinnamon
- A few small pieces of paper or shallow dishes
- A clean cloth or paper towel
Step 1: Find the Ant Trail
Watch where the ants are coming from. Look along windowsills, doors, cracks, baseboards, and underneath cabinets.
Finding the entry point is more important than simply treating the middle of the trail.
Step 2: Clean the Area
Wipe the surface thoroughly with soapy water.
This removes food residue and helps eliminate the scent trail ants use to navigate.
Step 3: Sprinkle Cinnamon
Place a small amount of ground cinnamon around suspected entry points and along areas where you’ve noticed ants.
You can also put cinnamon in small dishes near those locations if you don’t want loose powder scattered around.
Step 4: Refresh It Regularly
The smell becomes weaker over time, especially in humid areas.
Replace the cinnamon when the aroma fades or whenever the area gets cleaned.
Why Might Cinnamon Help?
Ants rely heavily on their sense of smell to communicate and navigate.
Strong-smelling substances may interfere with or discourage their movement, which is why cinnamon and other aromatic substances are often suggested as household ant deterrents.
However, cinnamon isn’t a guaranteed exterminator. It may discourage ants from certain areas, but it won’t necessarily eliminate an established colony.
The Most Important Step: Remove What Attracts Them
Even the strongest-smelling deterrent won’t solve much if ants continue to find an easy food source.
Try these simple habits:
- Wipe up crumbs and spills immediately.
- Store sugar, honey, and other sweet foods in sealed containers.
- Don’t leave pet food sitting out for long periods.
- Empty garbage regularly.
- Keep countertops clean.
- Fix dripping faucets and other moisture sources.
- Seal small cracks and gaps around doors and windows.
What About Other Natural Ant Deterrents?
You’ll find plenty of online suggestions involving coffee grounds, peppermint, vinegar, citrus peels, or various spices.
Some strong scents may temporarily discourage ants, but the effectiveness can vary considerably depending on the ant species and situation.
That’s why prevention and eliminating access to food and water are just as important as any DIY deterrent.
When a Home Remedy Isn’t Enough
If you keep seeing large numbers of ants despite cleaning and sealing entry points, there may be an established nest nearby.
In that situation, repeatedly spraying or scattering deterrents may only move the ants somewhere else.
A properly used ant bait can be more effective because worker ants carry the bait back to the colony. If the infestation is persistent or extensive, professional pest control may be the better option.
Final Thoughts
Cinnamon is an inexpensive trick worth trying when you’re dealing with a few wandering ants.
Just don’t expect it to keep ants away forever.
The real secret is combining a deterrent with good housekeeping: remove food sources, clean scent trails, block entry points, and address the colony if the problem continues.
A little cinnamon might help make your kitchen less inviting—but keeping ants away for good usually takes more than one kitchen ingredient!
