How to Get Rid of Ants in the House (Without Harsh Chemicals)
I’ll never forget the first time ants took over my kitchen. It started with just a few on the counter, but within days, there was a steady trail leading straight to the sugar jar.
My first instinct was to grab a can of chemical spray. It seemed like the fastest way to win the battle, but all it really did was leave my home smelling toxic, and the ants were back the next morning.
That was the moment I realized I needed a different approach. Instead of dousing my home in harsh chemicals, I started looking for natural fixes, things that were safe for me, my family, and the environment.
What surprised me most was how well these methods worked, often better than the sprays I had relied on before.
In this article, I’ll share what I learned: practical, chemical-free ways to get rid of ants and keep them from coming back.
Whether you’re in a big house or a small apartment, you’ll find action steps you can use right away to reclaim your space, without harsh solutions.
Why Ants Invade in the First Place

Ants don’t sneak into your home just to drive you crazy, they’re searching for food, water, and a safe spot to build their colony. Extension experts at NC State explain that identifying their entry points and food sources is the first step to controlling them effectively.
And here’s the bigger issue: researchers have found ants can carry bacteria like E. coli and Salmonella onto food-contact surfaces, making them a genuine health risk in your kitchen.
I learned this the hard way after finding ants trailing straight to my fruit bowl, something I thought was harmless until I realized they were also crawling over the counter where I prepped meals.
Action step: Do a five-minute “ant audit.” Check under appliances, around pet bowls, and along window frames for crumbs, leaks, or tiny cracks. This simple habit helps you understand why ants are showing up, not just how to get rid of them.
Once you know what’s drawing them in, you can start applying natural fixes that bring fast relief.
Quick Natural Fixes You Can Try Right Away
Vinegar spray bottle
If ants are already marching across your countertops, you don’t need chemicals to get quick results. Spraying vinegar along entryways disrupts their scent trails, making it harder for them to find food. Lemon juice and citrus peels also work thanks to d-limonene, which interferes with their sense of smell.
When ants built a trail near my back door last spring, one spray of vinegar broke it within minutes. Not glamorous, but incredibly effective.
Action step: Mix equal parts vinegar and water in a spray bottle and keep it under the sink. Wipe down any ant trails you spot. For outdoor ant hills, a pot of boiling water poured directly over the mound works instantly.
Of course, wiping trails only buys you time. To stop ants for good, you need to block where they’re coming in.

Quick fixes won’t last if ants can still find their way inside. Experts at Pesticide.org recommend sealing cracks with caulk, repairing leaks, and weatherstripping doors to stop infestations at the source.
Even temporary barriers like a line of petroleum jelly can help until you patch things properly.
I once discovered ants slipping in through a gap smaller than a pencil near my kitchen window. A quick bead of caulk ended weeks of frustration overnight.
Action step: Take ten minutes to inspect your home’s baseboards, windows, and doors. Seal at least one crack today. It’s an easy, one-time fix that saves you from repeat invasions.
Once the doors are closed to ants, the next step is making your home smell like a place they don’t want to be.
Natural Ant Deterrents That Actually Work
Peppermint extract
Some scents are pleasant to us but unbearable to ants. Essential oils like peppermint, tea tree, and clove are proven natural repellents.
Cinnamon, cayenne, or coffee grounds sprinkled along baseboards also disrupt their trails, plus they smell a lot better than chemical sprays.
When I started using peppermint oil in a spray bottle, not only did it repel ants, but my whole kitchen smelled refreshing, almost spa-like.
Action step: Add 10 drops of peppermint oil to a spray bottle filled with water. Mist it daily along countertops and entryways. It’s safe for kids and pets, eco-friendly, and doubles as a natural air freshener.
But even the best deterrents won’t work if your kitchen stays an open buffet.
Kitchen Habits to Keep Ants Out for Good
Most ant invasions trace back to food that’s easy to reach. Experts emphasize airtight storage and daily cleanup as the simplest way to cut off their food supply. Pet bowls are another overlooked hotspot, ants love leftover kibble as much as we love cookies.
In my apartment, switching pasta and cereal into sealed jars made all the difference. My pantry not only stayed ant-free, it looked Instagram-ready and cut down on food waste.
Action step: Choose one high-risk pantry item, sugar, flour, or cereal and move it into a sealed container today. Then get in the habit of wiping down counters each night. That five minutes of effort saves you from a full infestation.
And when prevention isn’t enough, DIY baits can help target the colony itself.
DIY Natural Ant Baits That Stop Colonies
Killing the ants you see won’t solve the bigger problem: the colony. DIY baits made from baking soda or Borax mixed with powdered sugar lure ants to carry the mixture back to the nest. Over time, this approach wipes out the source of the infestation naturally.
When I tested the baking soda trick, I tucked a small lid with the mixture behind my trash can. Within days, the trail vanished and it stayed gone for months.
Action step: Mix equal parts baking soda and powdered sugar. Place the mixture in a shallow dish along an ant trail, out of reach of pets and kids. It’s a low-cost, effective way to tackle colonies without harsh chemicals.

Once you’ve secured the inside, it’s time to look outside, where most infestations begin.
Outdoor Prevention So Ants Don’t Come Back
Most indoor problems start outdoors. NC State Extension advises trimming shrubs and trees that touch the house and keeping mulch or woodpiles at least 10 inches from foundations. These small steps stop ants from nesting near your home in the first place.
When I lived on a top-floor apartment, I learned ants can still come in through balconies. A simple sprinkle of coffee grounds around my potted plants kept them from setting up camp there.
Action step: Walk around your yard or balcony if you’re in an apartment. Trim vegetation, move mulch away from walls, and sprinkle coffee grounds or diatomaceous earth around planters. It’s prevention that pays off all summer.
And if the problem continues despite your best efforts, it might be time to call for eco-friendly backup.
When to Call Eco-Friendly Professionals
Sometimes, no matter how diligent you are, infestations persist, especially with carpenter ants or large colonies. Experts point out that complete eradication often requires identifying the ant species and combining baiting, sealing, and cleaning strategies.
The good news? Many pest control companies now offer green or chemical-free treatments that are safe for your home.
Action step: Search “eco pest control + your city” and save one contact in your phone. That way, you’ve got a sustainable backup plan if DIY solutions aren’t enough.
And if you’re still wondering which remedies to try first or how to keep ants from sneaking back, these quick FAQs cover the most common questions homeowners face.
