Does Borax Kill Ants? 

Yes, Borax indeed eradicates ants. This common household cleaning product has a secret double life as an effective, budget-friendly, and environmentally safer alternative to commercial ant pesticides. So next time you spot a pesky ant trail, consider reaching for the Borax! 

How Does Borax Kill Ants? 

Ants are attracted to the sweet mixture of Borax and sugar, unknowingly carrying lethal particles back to their colony. Once ingested by the ants, the Borax disrupts their digestive system and gradually causes their demise. It’s like a Trojan Horse strategy for ants, but instead of warriors, we’re using chemistry! 

So remember, Borax isn’t just your grandma’s favorite laundry booster. It’s a pest enthusiast’s secret weapon against ants, cleverly working behind the scenes to protect our homes. While it may take a little more patience than traditional ant sprays, the results are absolutely worth the wait. 

To enhance its effectiveness, remember to always mix Borax with a sweet bait like sugar or honey to draw the ants in. A 50/50 mix generally works well. Also, it’s critical to remember that while Borax is less toxic than many commercial pesticides, it can still be harmful if ingested by pets or children. So, use it with caution, always out of reach of the little ones. 

How Long Does It Take For Borax To Kill Ants? 

Although it may test your patience, it is certainly worth the wait. Unlike instantaneous sprays, Borax works methodically. It takes approximately 24 to 48 hours to kill individual ants, while the full colony might require a week or two to be eradicated completely.  

While it might not be as quick as commercial pesticides, it allows the Borax mixture to reach the heart of the colony, ensuring a thorough solution to your ant problem. 

The Dangers of Using Borax to Kill Ants 

As we mentioned earlier, Borax can be harmful if ingested by pets or children. Symptoms can range from upset stomachs to more severe reactions in cases of large ingestion.  

It’s also crucial to avoid getting Borax in your eyes or breathing in its dust, as it can irritate these sensitive areas. And let’s not forget our environment – while Borax is less harmful than many commercial pesticides, excessive use can lead to accumulation in soil and water, potentially harming plants and wildlife. 

Remember, the key to safely using Borax for ant control is responsible handling and usage. Always ensure it’s out of reach from those who might accidentally ingest it, and be mindful of your local ecosystems. When in doubt, seek advice from pest control professionals. 

How to Use Borax to Kill Ants? 

So, how does one use Borax to wage war against these tiny invaders? Here’s the step-by-step process to create your own homemade ant bait using Borax. 

  • First, mix equal parts of Borax and a sweet substance like sugar or honey. This blend is irresistible to ants, drawing them in with the promise of a sugary feast. 
  • Next, place this mixture on a flat, disposable surface like a piece of cardboard or a bottle cap. Remember to keep it away from areas frequented by pets or children. 
  • Then, simply wait. As the ants find this tempting treat, they’ll carry it back to their colony, sharing it with their kin. As we discussed earlier, the Borax then works its way through their systems, spelling doom for the colony. 
  • Lastly, ensure to clean up the bait stations after the ants have been dealt with, taking care not to leave any traces of Borax behind. 

Remember, the key to success here is patience. It might take a while before you see results, but rest assured, the Borax is working behind the scenes. In the end, you’ll have a kitchen free of ants, and the satisfaction of knowing you did it yourself. 

Instructions for Making Homemade Ant Killer with Borax 

Having explored the hows and whys, let’s delve into the practical side of things. Here, we’ll provide step-by-step instructions to create your own homemade ant killer with Borax. 

Mixing Borax and Sugar to Kill Ants 

First on our list is the classic sugar-Borax mix. Start by combining equal parts of sugar and Borax in a bowl. Stir until you have a uniform mixture. Then, add just enough water to create a syrupy solution. This blend serves as an irresistible bait for ants, luring them with the sweetness of the sugar and sealing their fate with the Borax. 

Using Borax and Peanut Butter to Kill Ants 

For ants with a preference for protein over sugar, a peanut butter-Borax mixture can be a game-changer. Simply mix two tablespoons of peanut butter with a teaspoon of Borax. The creamy texture of the peanut butter masks the presence of Borax, making it an effective bait for protein-loving ants.

Mixing Borax and Honey to Kill Ants 

Lastly, a Borax and honey mixture is another great option. Mix equal parts of Borax and honey until well combined. The sweet, sticky nature of honey acts as an excellent bait, and the Borax within does the rest. 

Regardless of the bait you choose, always place the mixture in a location frequented by ants but out of reach of pets and children. Remember, Borax can be harmful if ingested, so it’s important to use it responsibly. And don’t forget – patience is key. You may not see results immediately, but rest assured, your homemade ant killer is hard at work.

Learn More About Borax 

Borax, also known as sodium borate, is a naturally occurring mineral found in deserts, lake beds, and hot springs around the world. It’s been used for more than a century in various household tasks such as laundry, cleaning, and yes, even pest control.  

In its raw form, it’s a colorless crystal, but most of us are familiar with it as a white powder. Despite its humble appearance, Borax’s versatility and effectiveness make it a staple in many homes, and a must-have in every pest enthusiast’s toolkit. 

Comparison of Borax and Boric Acid 

Now, let’s tackle a common point of confusion – Borax versus boric acid. While their names sound similar and they come from the same boron family, they’re not identical.  

Boric acid is derived from Borax and has a different chemical structure. It’s often used in roach and termite pesticides, whereas Borax is popular for ant control. 

Both can be used in homemade pest control remedies, but they work slightly differently. Boric acid is more toxic and can kill ants faster, but it’s also more harmful to humans and pets. Borax, on the other hand, is less toxic but takes a bit longer to exterminate ants. So, if safety is your top priority, Borax might be the better choice. 

At the end of the day, whether you choose Borax or boric acid for your ants control needs, it’s essential to use them responsibly. And remember, knowledge is power. The more we understand about these tools at our disposal, the better equipped we’ll be to handle any unwelcome visitors.


To wrap up our discussion on Borax and ant control, let’s address some frequently asked questions that might be on your mind. I’ve always believed that no question is too small, especially when it comes to something as important as keeping our homes pest-free. 

Is Borax the Same as Boric Acid? 

Boric acid is actually derived from Borax and has a different chemical structure. Both can be used in pest control, but Borax is generally safer for humans and pets and is most commonly used for ant control. 

What Happens to Ants When They Eat Borax? 

When ants eat Borax, it interferes with their digestive system and gradually kills them. The Borax disrupts their stomach and metabolism, leading to their demise. What’s more, worker ants carry the Borax-laced bait back to their colony, feeding it to other ants, including the queen, which leads to the destruction of the entire colony. 

Does Borax Kill Ants Immediately? 

No, Borax doesn’t kill ants immediately. It takes around 24 to 48 hours to kill individual ants, while eradicating an entire colony might take up to a week or two. This slower process is actually a benefit, as it allows the worker ants to carry the Borax bait back to their colony, ensuring that it reaches and kills even the ants that stay hidden away inside.
