You walk into the kitchen for a midnight glass of water and there they are. A tiny, pulsating line of scouts marching across your granite countertop like they own the place. It’s enough to make your skin crawl. Honestly, your first instinct is probably to grab the nearest heavy-duty chemical spray and go to town. But if you have kids or pets—or if you just don't like the idea of turning your kitchen into a hazmat zone—you're likely looking for a get rid of ants home remedy that actually works without the toxic fallout.
The internet is full of "hacks." Most of them are garbage.
I’ve spent years researching urban entomology and talking to professional exterminators who have seen it all. The reality is that ants are incredibly sophisticated. They aren't just random bugs; they are a collective intelligence. If you kill ten of them with a damp paper towel, the colony just sends twenty more. You have to be smarter than the hive mind.
Why your get rid of ants home remedy usually fails
Most people think of ant control as a search-and-destroy mission. It isn't. It's a chemistry project mixed with a little bit of psychological warfare.
The biggest mistake? Killing the scouts immediately. When you see a lone ant, that’s a scout. It’s laying down a pheromone trail—a literal chemical "yellow brick road"—for the rest of its sisters to follow. If you spray that ant with a contact killer, you’ve dealt with the symptom, not the disease. The colony is still back in the wall, or under your porch, or deep in the soil, churning out thousands of new workers.
Effective home remedies have to do one of two things: they either mask those pheromones so the ants get lost, or they act as a "Trojan Horse" that the ants carry back to the queen.
The White Vinegar Myth and Reality
You've probably heard that white vinegar is the holy grail of DIY pest control. Is it? Sorta.
Vinegar is an acetic acid. It’s brilliant at cutting through the waxy pheromone trails I mentioned earlier. If you mix a 50/50 solution of white vinegar and water and spray it where you see ants, you aren't "killing" the colony. You’re just wiping the GPS coordinates they used to find your sugar bowl. It’s a temporary fix. It buys you time.

Dr. Edwin Rajotte, an entomologist at Penn State, has noted in various extension publications that while vinegar disrupts trails, it lacks the residual power to stop a determined colony. You’ll see them back in 24 hours once the scent dissipates. If you want a real get rid of ants home remedy, you need something that interrupts their biology, not just their nose.
The Borax Strategy: The Only Real Heavy Hitter
If you want a home remedy that actually eliminates the nest, you have to talk about Borax. Specifically, Sodium Borate.
This stuff is a mineral. It’s commonly found in laundry boosters like 20 Mule Team. For humans, it’s relatively low-toxicity in small amounts (though you still shouldn't eat it), but for ants, it’s a slow-acting stomach poison. This "slow-acting" part is the secret sauce. If it killed them instantly, they’d die on your kitchen floor. We want them to live long enough to bring a "gift" back to the queen.
How to mix it right
Don't just sprinkle dry Borax. Ants won't eat it. They aren't stupid. You have to trick them.
- Liquid Bait: Mix 1/2 teaspoon of Borax with 1/2 cup of warm water and 2 tablespoons of sugar. Soak cotton balls in this syrup and place them in shallow bottle caps near the ant trails.
- Paste Bait: Mix Borax with peanut butter or honey. Some ants (like Carpenter ants or Grease ants) crave protein and fats rather than sugar.
You’ll notice something terrifying at first: more ants.
Seriously. You’ll see a swarm around your bait. Resist the urge to scream. Let them eat. They are gorging themselves and carrying that poisoned sugar back to the heart of the nest. Within 48 to 72 hours, the entire population will collapse. This is the most effective get rid of ants home remedy backed by actual science.
Essential Oils: More Than Just a Good Smell
Let's talk about Peppermint and Cinnamon. People love these because they make the house smell like a spa instead of a chemistry lab.

According to a study published in Journal of Economic Entomology, certain essential oils—specifically Peppermint and Clove—have genuine repellent properties. Peppermint oil contains menthol, which is a natural biopesticide for many small insects.
However, there’s a catch. Most people use "scented oils" from the dollar store. Those do nothing. You need high-concentration, pure essential oils. If you put 15-20 drops of pure peppermint oil in a spray bottle with water and douse your baseboards, you create a chemical barrier that ants find physically painful to cross.
Cinnamon is a bit different. There is an old wives' tale that ants won't cross a line of cinnamon. This is actually true, but not because of the spice itself. It’s because the fine powder of ground cinnamon acts as a desiccant and interferes with their spiracles (the tiny holes they breathe through). But let's be real: do you want a line of brown powder all over your house? Probably not. Stick to the peppermint spray for the entry points like window sills and door frames.
Diatomaceous Earth: The "Glass Shards" Approach
If you have an infestation in your walls or under the floorboards, Food-Grade Diatomaceous Earth (DE) is your best friend.
DE is made of fossilized remains of tiny aquatic organisms called diatoms. To us, it feels like soft flour. To an ant, it’s like walking over a field of broken glass. It slices through their exoskeleton and dries them out from the inside.
Pro tip: You have to get the "Food Grade" version. The stuff used for pool filters is chemically treated and dangerous to breathe. Dust it lightly—and I mean lightly—behind appliances. If you pile it up, the ants will just walk around it. It needs to be a nearly invisible dusting so they unknowingly march right through it.
The "Water and Soap" Panic Button
Sometimes you don't have Borax. You don't have Peppermint oil. You just have a hundred ants on your sandwich.

Dish soap.
Plain old Dawn or any liquid dish soap breaks the surface tension of water and suffokes ants almost instantly. It also breaks down the waxy coating on their bodies. A spray bottle with soapy water is the best way to handle an immediate "breakout" while you prepare your long-term Borax baits. It’s safe, it’s cheap, and it cleans your counters at the same time.
Why are they in your house anyway?
You can bait and spray until you're blue in the face, but if you don't fix the "why," they’ll be back next season. Ants are remarkably efficient foragers. They can smell a single crumb of a granola bar from across a backyard.
Check your houseplants. Sometimes the "infestation" isn't coming from outside; it’s living in the potting soil of your Monstera. If you see ants crawling in and out of a pot, you likely have an aphid problem. Aphids secrete a sweet liquid called honeydew, and ants actually "farm" them like tiny cows. Treat the aphids with Neem oil, and the ants will lose their food source and leave.
Check your seals. If you can see daylight through the bottom of your front door, an ant sees a ten-lane highway. Replace your weather stripping. It’s a $10 fix that does more for pest control than a $500 exterminator visit.
Actionable Steps for a Pest-Free Home
If you're dealing with a current invasion, follow this specific order of operations to maximize your results:
- Identify the trail. Do not clean it yet. Watch where they are going and where they are coming from.
- Deploy the Borax bait. Use the sugar-water-Borax cotton ball method. Place it directly in the path of the trail.
- Wait 24 hours. You will see more ants. This is good. It means the "Trojan Horse" is working.
- Seal the entry. Once the ant traffic dies down (usually day 3), use caulk to seal the hole they were using.
- Sanitize. Now you can use the 50/50 vinegar and water spray to wipe down your counters and eliminate the old pheromone trails so new scouts don't find the old path.
- Maintain. Keep your sink dry. Ants need water just as much as food. A leaky faucet is basically an oasis in the desert for a colony.
Natural pest control isn't about one "magic" ingredient. It's about consistency. If you provide a food source, they will find it. If you break their communication lines and use a slow-acting bait to hit the queen, you’ll win the war. Just remember to keep the Borax and essential oils out of reach of your pets, even though they are "natural." Natural doesn't always mean edible.
Stick to the Borax for the kill and the Peppermint for the shield. That combination is the most reliable way to handle the situation without calling in the pros.
