We all know baking soda’s culinary prowess, but who knew it could also be a secret weapon against those tiny home invaders? Today, I’ll reveal the magic of using baking soda to get rid of ants once and for all!  

Let’s get ready to reclaim our homes from these six-legged intruders! 

What Is Baking Soda? 

Alright, first things first – what exactly is baking soda? Well, it’s a powdery, white substance also known as sodium bicarbonate. You’ve likely used it in baking to make cakes and cookies rise to fluffy perfection. But trust me, its prowess doesn’t end there. Baking soda has some remarkable properties that can deal with ants in a surprisingly effective way!

Does Baking Soda Kill Ants? 

The answer is a resounding yes! Baking soda acts as a natural desiccant, which means it dehydrates the ants when they come into contact with it. This dehydration process is lethal for the tiny intruders, making it an excellent ant-killing option. 

The Science Behind Killing Ants with Baking Soda 

I won’t bore you with complex scientific jargon, but a little understanding of how baking soda works against ants is fascinating. When ants walk over the baking soda, they carry it back to their nests. Ants are social creatures, and they share food with their colony members. This unfortunate chain of events leads to the baking soda spreading through the nest, dehydrating and ultimately eliminating those bothersome ants.

How to Kill Ants with Baking Soda? 

Ready to take action against those tiny trespassers? Here’s how you can use baking soda to show ants the exit door: 

  • Locate Their Entry Points: Keep an eye on the ants’ trails to find out where they’re sneaking into your living space. 
  • Create Your Baking Soda Ant-Killing Mix: Mix equal parts of baking soda and powdered sugar. The sugar will lure the ants in, and the baking soda will work its magic. 
  • Place the Mixture Near Their Path: Sprinkle the baking soda-sugar mixture near the ants’ entry points, ensuring they’ll come across this lethal concoction. 
  • Be Patient: It might take some time, but soon you’ll witness the remarkable effects of baking soda on the ant population. 

How Long Does It Take for Baking Soda to Kill an Ant? 

Well, it’s not an instantaneous zap-like action you’d see in sci-fi movies. The process can take a few days, depending on the size of the ant colony and how well they’ve distributed the mixture within their nest.  

But rest assured, the wait is worth it. Before you know it, you’ll notice a significant decrease in ant activity, and soon enough, they’ll be history! 

Are There Any Other Natural Methods That Can Replace Baking Soda? 

I’ve got here a list of some fantastic options that can work hand-in-hand with baking soda or step up to the plate on their own. Let’s explore these ant-repelling superheroes! 


If you’re looking for a spicy solution to your ant problem, black or cayenne pepper might just be the answer. Ants loathe the pungent smell of pepper, so sprinkling it near their entry points or creating barriers can deter them from marching further into your abode. 


Ah, the refreshing scent of peppermint is a delight for us, but ants find it utterly repulsive. You can use peppermint essential oil diluted with water to create a natural ant repellent spray. Spray it along baseboards, windowsills, and doorways to send those ants scurrying away. 


The acidic nature of vinegar makes it an excellent ant deterrent. A simple mixture of equal parts vinegar and water sprayed on ant-infested areas disrupts their scent trails, making it challenging for them to navigate and communicate. Plus, it leaves your home smelling fresh! 

Tea Tree Oil 

Tea tree oil is well-known for its antimicrobial properties, but it also acts as a potent ant repellent. Mix a few drops of tea tree oil with water and wipe down surfaces to keep ants at bay while enjoying the pleasant aroma. 


Who knew something as simple as chalk could thwart ant invasions? Drawing a line with chalk near entry points creates an effective barrier, as ants dislike crossing this white powdery substance. 


Yes, even plain water can work its magic against ants. Placing a bowl of water with a few drops of dish soap near ant-infested areas can trap and drown these unwelcome guests. 


Salt isn’t just for seasoning your meals; it can also help repel ants. Sprinkle a line of salt across doorways or windowsills to discourage ants from entering. 


The sweet and spicy scent of cinnamon might be enticing to us, but ants can’t stand it. Sprinkle cinnamon powder near ant hotspots or use cinnamon essential oil mixed with water to create a potent ant repellent spray. 

Diatomaceous Earth 

Though it may sound fancy, diatomaceous earth is a natural and harmless ant assassin. This fine powder, made from fossilized algae, dehydrates ants upon contact, similar to baking soda. Sprinkle it strategically where ants roam, and let nature take its course. 


Is Baking Soda Safe for Children?

Absolutely! One of the fantastic advantages of using baking soda is its safety for children and pets. Unlike chemical pesticides, baking soda poses no harm when used responsibly. 

Will Baking Soda Kill Every Type of Ant? 

While baking soda proves to be effective against many types of ants, there might be some species more resistant to its effects. However, it remains a worthy and safe option for most common household ants. 

How Can I Make Sure the Ants Don’t Come Back? 

Prevention is the key! Keep your home clean, store food properly, and seal any cracks or openings that might serve as entry points for ants. Using natural repellents like peppermint and vinegar can also help keep ants at bay. 

Compare Baking Soda and Adhesive Traps for Killing Ants 

Both baking soda and adhesive traps offer effective ways to deal with ant infestations. While baking soda is a natural and non-toxic option, adhesive traps are designed to catch and trap ants, offering a physical approach to elimination. 

In conclusion, Pestweek‘s caring and effective methods show that baking soda can indeed be used to eliminate ants. Trust Pestweek’s expert tips to safely apply baking soda and say goodbye to ant infestations. Embrace a pest-free home and peace of mind, thanks to Pestweek’s expert solutions.
