Does Baking Soda Kill Ants?

Everyone’s got a secret ant-busting remedy—your neighbor swears by cinnamon, your aunt suggests vinegar, and someone online will die on their chalk-covered sword. But when those tiny invaders start marching through your kitchen like they own the place, you want something that actually works.

Baking soda often tops the list of natural solutions. It’s cheap, it’s sitting in your pantry, and it sounds like a science experiment waiting to happen. But can this everyday kitchen staple really take down an ant army? Let’s find out if baking soda is myth or magic, and answer the question “Does Baking Soda Kill Ants?”

Baking soda can kill ants, but don’t expect instant results. When ants eat it, it reacts with the acid in their stomachs. Kind of like that fizzy baking soda and vinegar volcano from elementary school, it creates gas and internal pressure that eventually kills them.

This method can also work by drying out their exoskeletons as it sucks up moisture. While it’s faster and more effective on soft-bodied creatures like slugs and snails, it can still do the trick for ants.

A popular DIY trick is to mix baking soda with sugar. The sugar lures them in, and the baking soda seals their fate. Because ants share food with the colony, this sneaky snack can take out more than just one ant which is the only way to truly get rid of ants—kill the whole nest.

Baking soda is safe for kids and pets. It’s cheap, non-toxic, and worth trying. So does baking soda kill ants? It definitely can…just remember each circumstance is different, and be prepared that it might not knock out a massive infestation all on its own.

While using our professional pest control for large infestations is usually necessary, there are some DIY options you can try when battling a smaller issue. Just always do your own research to be sure the products suggested are safe to use for your family environment and know that none of these DIY options come with a guarantee.

1. Borax and Sugar: It’s an Inside-Job

Another popular ant-killing combo is borax and sugar—a method that works similarly to baking soda, but with a more potent punch. Unlike baking soda, borax is technically poisonous and wreaks havoc on the ants’ digestive systems once ingested.

Despite common myths, borax and baking soda are not the same. Borax is a naturally occurring mineral with a higher alkalinity but still toxic to humans and animals if ingested. Baking soda is a lab-made mix of sodium chloride and ammonia.

To whip up a simple bait mix 2 tablespoons each of sugar and borax with a splash of water until it forms a syrup, and place it in a disposable container near entry points. The sugar lures them in—and the borax does the dirty work. Just be sure to keep out of reach of children and pets.

2. Vinegar Spray: Throw Them Off The Trail

Vinegar is an ant’s worst enemy—and YOUR eco-friendly ally. Its strong scent scrambles the pheromone trails ants rely on to communicate and navigate. Without those chemical breadcrumbs, ants easily get lost.

To throw them off their game, just mix equal parts vinegar and warm water (two cups each works well), pour it into a spray bottle, and shake. Spritz it along ant trails, entry points, and other hotspots.

The smell may be strong at first, but it will fade for you—while it wipes out the ants’ entire roadmap. Simple, safe, and surprisingly effective.

3. Salt: A Cheap Alternative

Of all the ways to battle ants, plain old salt might be the simplest—and cheapest—weapon in your arsenal. Salt works by drying out the ants’ exoskeletons and irritating their legs, similar to how baking soda kills ants.

If sprinkling a salt barrier around your home isn’t up your alley, try a DIY salt spray instead. Mix two tablespoons of salt with every cup of warm water, shake it up, and spray it around doorways, windowsills, and anywhere you’ve spotted the tiny invaders. Not only does salt disrupt their chemical trails, but it’s also a budget-friendly, pet-safe way to keep ants from marching in.

4. Cucumber Peels: Stink It Up

While a fresh cucumber slice might brighten your salad or make your water super refreshing, ants want nothing to do with this fruit (yes, it’s technically a fruit!). The bitter taste and strong scent are a major turn-off for them. That’s why placing cucumber peels near ant trails or entry points can help keep them at bay.

It’s a simple, natural trick that turns kitchen scraps into an eco-friendly pest control option. Just drop a few peels where ants are creeping in—and watch them turn right back around.

Another plus? Many other pests hate them too.

5. Chalk: A Line They Won’t Cross

Chalk might seem like it’s only good for playing hopscotch and solving math problems, but it’s also a great ant deterrent. As mentioned before, these tiny battalions rely on scent trails (pheromones) to navigate and communicate—and just like with vinegar—chalk disrupts those chemical highways.

Draw a thick line of chalk along windowsills, doorways, or wherever ants are marching in. Most won’t dare cross it, making this a surprisingly easy and non-toxic way to keep them out. No harsh chemicals, no mess—just good old-fashioned sidewalk strategy put to work indoors. Without the strong smell of vinegar.

6. Dish Soap & Water: On-hand Solution

A soap and water mixture is almost too easy, but many people swear by it. Plus, almost everyone already has it under their kitchen sinks. Spraying it directly on the ants can have a similar effect to over-the–counter pest products. Mix a spray bottle with warm water and add around ten drops of dish soap. Spray this whenever you see ants and especially along their trails.

It’s a cost-effective method that’s safe for children and pets and won’t exacerbate breathing issues in those with asthma or other problems.

7. Neem Oil: Is It Right For You?

Thanks to a powerful compound called azadirachtin, neem makes it tough for ants and other bugs to breathe, keeping them at bay. It’s been around for centuries and used in all sorts of medicinal and agricultural ways. It’s also effective against all sorts of pests—from ants and aphids to garden invaders like mealybugs.

The easiest and safest way to use it is through Neem Oil. Mix it with water and a little dish soap to create a potent spray, or you can sprinkle neem powder around your garden to ward off ants and pests. It’s a natural, eco-friendly way to keep your space pest-free without harsh chemicals. Just like with all home-remedies, do your research to ensure this method is right for you—especially if you are pregnant or have small children or pets.

Additional Tip: Used properly, neem can be great for plants (after all, it comes from the Neem tree) BUT there is a right and wrong way to use it. Neem oil should always be diluted properly before applying. Using it full-strength can sometimes cause stress to plants. Also, avoid spraying neem oil during the hottest part of the day or under direct intense sunlight to prevent damage.

8. Diatomaceous Earth: Every Home Should Have It

Diatomaceous earth (DE) might look like nothing more than a soft white powder, but don’t let appearances fool you—this stuff is a powerhouse. Made from fossilized algae called diatoms, it’s packed with silica and has uses ranging from natural pest control to human wellness trends (yep, some people even take food-grade DE for digestion and detox).

When it comes to ants and other insects, DE is like walking on broken glass. The powder may feel harmless to us, but its microscopic, razor-sharp edges slice through insect exoskeletons and dehydrate them from the inside out. Sprinkle it along baseboards, entry points, or anywhere you see bugs, and they won’t last long.

It’s non-toxic, eco-friendly, surprisingly versatile, and great for everything from chicken coops to gardens to kitchen corners. While it doesn’t kill everything, DE might just be the not-so-secret weapon of natural pest control.

9. Lemon Juice: When Life Gives You Lemons, Make Ant Bait

From lemonade to a slice of lemon meringue pie, lemons are very versatile in the kitchen. However, you may not know it can also be a natural ant deterrent. While you may love using lemons in your cooking, ants can’t stand it.

The strong scent of lemon disrupts ants’ chemical pathways, rendering them unable to find food. Not only does lemon juice serve as a natural ant control, but it also leaves your home smelling like the freshest on the block.

When you’re juicing your lemons, don’t throw out the peels. For extra protection, you can place the peels in your garden or near the entrance to your home. But please note that lemon peels can be toxic to pets so, you guessed it, do your research!

10. Peppermint Oil: Not-So-Cozy for Ants

A list of all-natural pest control methods for killing ants would not be complete without mentioning peppermint. While we love it in candy, ice cream, and hot cocoa, ants can’t stand the strong, minty aroma. Just mix peppermint oil with water in a spray bottle, and you’ve got an eco-friendly bug barrier.

Bonus: It doesn’t just deter ants—plenty of other pests hate it too. The refreshing scent that perks up your home and makes you think of sipping hot cocoa during the holidays? It overwhelms tiny insects and makes it hard for them to breathe. So while your house smells like Christmas, ants will be celebrating around a different tree in someone else’s house.
