How to Get Rid of Ants Naturally at Home: 7 Grandma Secrets

Nothing ruins a peaceful morning quite like finding a marching band of tiny black ants parading across your kitchen counter, does it, sweetheart?

I know just how frustrating it is to feel like you've lost control of your own kitchen to these determined little creatures. But before you run to the local store for those heavy chemical sprays that smell terrible and aren't safe for the grandkids or your beloved pets, let Grandma share some wisdom. Today, I am going to teach you exactly more tips on how to get rid of ants naturally at home using simple pantry staples you probably already have in your cupboards right now.

You see, ants are simple creatures driven entirely by smell. Once a single scout finds a tiny crumb of sugar on your counter, it leaves behind an invisible scent trail—like a highway map—for all its brothers and sisters to follow. Our goal isn't just to wipe away the ants we see, but to scramble their maps and make your home smell absolutely dreadful to them, while keeping it smelling beautiful for you.

Your Natural Ant-Busting Shopping List

Before we jump into my favorite recipes, let's gather our supplies. You don't need to spend a fortune. Take a peek into your pantry and see how many of these household items you already have on hand:

Natural Ingredient	What It Does to Ants	Best Place to Use It
White Vinegar	Destroys scent trails instantly	Countertops, baseboards, floors
Baking Soda & Sugar	Safe, slow-acting natural trap	Corners, under appliances
Ground Cinnamon	Natural barrier they won't cross	Windowsills, doorways, cracks
Peppermint Essential Oil	Overwhelms their sense of smell	Entry points, trash cans
Food-Grade Diatomaceous Earth	Dries out their outer shells	Behind cupboards, wall voids

Now that you have your supplies ready, let me walk you through my seven favorite tried-and-true tricks. These have kept my kitchen clean, safe, and pest-free for over fifty years, and they will do the exact same for yours!

1. The Magic 50/50 White Vinegar Spray

This is my absolute go-to, dear. It is simple, cheap, and works like absolute magic. Ants communicate with each other using pheromones, which are invisible smell chemicals. When you spray white vinegar, the strong acid smell completely erases those scent trails, leaving the ants lost and confused.

To make my favorite spray, mix equal parts of plain white vinegar and warm tap water in an empty spray bottle. Shake it up gently. Whenever you spot an ant trail, spray them directly and wipe them away with a clean microfiber cloth. Then, spray the area again and let it air-dry. The vinegar smell fades for us humans in about ten minutes, but to an ant, it remains a giant stop sign for days.

2. The Sweet Baking Soda Deception

Sometimes you need a trick that the ants will actually carry back to their nest. This is where my baking soda trap comes in handy. You see, ants cannot digest baking soda, but they can't tell the difference between baking soda and powdered sugar because the grains are so similar in size.

Mix equal parts of baking soda and powdered sugar in a small shallow dish or an old jar lid. Do not use regular granulated sugar, honey, or syrup—the ants will just pick out the sugar and leave the baking soda behind. Place these little lids near the places where you see them entering. The scouts will carry this sweet mixture back to the queen and the rest of the colony, solving your problem right at the source.

3. Draw the Line with Cinnamon

My grandmother taught me this one when I was just a little girl living in the countryside. Ants absolutely despise the strong smell of ground cinnamon, and they refuse to walk through it because it interferes with their breathing. It acts like a tiny, invisible brick wall.

Take ordinary ground cinnamon from your spice rack and draw a solid line across your windowsills, patio door thresholds, or any small cracks in the baseboards. If you want to keep things looking neat and tidy, you can dip a cotton swab in cinnamon essential oil and draw a wet line along those same spots. It works beautifully, and your home will smell like freshly baked cookies!

4. The Peppermint Essential Oil Shield

If you prefer a fresh, clean scent, peppermint oil is your best friend. Like cinnamon, peppermint has a very intense aroma that overwhelms the delicate senses of these little critters. They will actively run away from it to save their own senses.

Add about fifteen to twenty drops of pure peppermint essential oil to two cups of water in a spray bottle. Give it a good shake before every use, and spray it around your door frames, window frames, and around the base of your kitchen trash cans. For some extra peace of mind, you can learn more about how different scents affect household pests in The Spruce's guide to natural pest control.

5. Fresh Lemon Juice Barriers

Did you know that the citric acid in fresh lemon juice is toxic to the scent trails of ants? If you don't have vinegar on hand, or if you simply dislike the smell of it, lemons are an excellent substitute that leaves your kitchen smelling bright and sunny.

Squeeze the juice of a fresh lemon directly into a spray bottle or onto a cotton ball. Rub the juice along your thresholds, windowsills, and any outdoor entry points. You can also toss your leftover lemon peels into your garden beds near the foundation of your house to keep them from approaching the walls in the first place.

If you have a particularly stubborn colony under your floorboards, don't lose heart! I have put together more tips on how to get rid of ants naturally at home to help you tackle those extra-difficult spots.

6. Food-Grade Diatomaceous Earth (The Secret Weapon)

If you have a serious infestation that just won't budge, it's time to bring out the big guns. Diatomaceous earth—make sure you only buy the kind clearly labeled "Food-Grade"—is a completely natural powder made from the fossilized remains of tiny aquatic organisms called diatoms.

To us, this powder feels as soft as baby powder. But to an insect, the microscopic edges are incredibly sharp. It wears away their waxy outer protective coating, causing them to dehydrate and perish. Dust a very thin layer of this powder behind your oven, under the refrigerator, and inside the cabinets where you store your food. Since it is food-grade, it is completely non-toxic to your dogs, cats, and little ones.

7. The Simple Cornstarch Method

This is a quick and clean trick if you happen to find a sudden, large cluster of ants on your floor. Instead of vacuuming them up while they are running wild, cover them completely with a heavy dusting of ordinary cornstarch.

The cornstarch coats their bodies, stopping them in their tracks and preventing them from escaping. Once they are still, you can easily sweep them up into a dustpan or vacuum them away without any mess or scattering. Afterward, wipe the area down with your vinegar spray to make sure no scent trails remain behind.

Simple Ways to Keep Them from Coming Back

Once you have successfully cleared the current invaders out, we want to make sure they never want to return. A little bit of daily maintenance goes a very long way, sweetheart:

• Keep counters dry: Ants aren't just looking for food; they are often searching for a drink of water. Fix leaky faucets and wipe down wet sinks before bed.
• Store food in airtight glass jars: Cardboard boxes and thin plastic bags are easily chewed through. Glass or heavy-duty plastic containers with sealable lids are much safer.
• Wash your pet bowls: Wet pet food left out overnight is a five-star buffet for a scout ant. Pick up the bowls after your furry friends are done eating, and wipe down the floor underneath.
• Seal the gaps: Walk around your home with a tube of silicone caulk and seal up any tiny cracks around your windows, doors, and pipes.

There you have it, my dear! With a little patience and these simple pantry items, you can reclaim your cozy home without using a single drop of harsh chemicals. Keep your chin up, take it one step at a time, and you'll have a pest-free home in no time!

Frequently Asked Questions

Why do ants keep coming back even after I clean my kitchen thoroughly?

Even if you wipe up every single visible crumb, the invisible scent trails (pheromones) left behind by previous scouts remain on your surfaces. If you don't wash those trails away with an acidic cleaner like white vinegar or lemon juice, new ants will easily follow the path straight back into your home.

Is vinegar safe to use on all types of countertops?

While vinegar is wonderful for laminate, tile, and sealed wood, you should never use it on natural stone countertops like granite, marble, or quartz. The acid in the vinegar can dull and etch the beautiful polished finish of natural stone. For those surfaces, stick to warm soapy water or mild dish soap instead.

Is food-grade diatomaceous earth safe for my indoor pets?

Yes, food-grade diatomaceous earth is entirely safe for dogs and cats, as it is non-toxic. However, because it is a very fine powder, try not to kick up a big cloud of dust when applying it, as breathing in any kind of fine dust can irritate their sensitive lungs and noses.

How long does it take for these natural remedies to work?

Repellents like vinegar and peppermint work instantly to turn ants away, but bait traps like baking soda and sugar can take anywhere from three to seven days. This is because the ants need time to carry the mixture back to the nest to share it with the rest of the colony.
