Borax, also known as sodium borate, is a naturally occurring mineral often used in cleaning, laundry, and other household tasks. Traditionally found in powder form, it’s long been praised for its ability to disinfect, deodorize, and even deter pests. When it comes to borax for ants, this everyday product can help manage infestations. Because it acts as a slow-acting poison, it gives worker ants time to carry the bait back to the ant colony, targeting the problem at its source.
Does Borax Actually Kill Ants?
Borax does kill ants, but slowly. Its delayed effect is actually what makes it so effective. Instead of just wiping out the ants instantly, borax allows ants to return to the nest, spreading the poison. This can reduce the entire ant colony over time. An ant exterminator can identify and apply targeted treatment to hotspots for faster results.

How Borax Affects Ants
Borax and ants don’t mix well. When ants eat borax, the compound reacts with the acid in their digestive system and disrupts their metabolism. It essentially prevents them from absorbing nutrients, leading to a gradual shutdown of internal functions. Since it works slowly, worker ants can carry it back to the nest and share it with others. That’s why using borax for ants can help to wipe out the entire colony.
Borax vs. Other Ant Killers
Unlike sprays that kill on contact or traps filled with strong chemicals, like synthetic pyrethroids or organophosphates, killing ants with borax offers a lower-toxicity option. The Borax solution for ants works more gradually and reaches the core of the problem. It may take longer, but it has the potential to be more effective if used correctly.
Borax must be mixed with sugar or protein and water to attract ants. Ants like sugar and protein, but their preferences vary. For instance, foragers prefer sugar combined with protein or amino acids instead of plain sugar solutions.
What You’ll Need Before You Start
Most of the items needed for a borax ants recipe are things you might already have in your kitchen. Being prepared helps you act fast when ants appear. Remember, while DIY baits can be helpful, they may not solve the problem entirely. To protect your home long-term, it’s a good idea to call professional ant exterminators. However, if you do decide to tackle the problem yourself, you’ll need the following items:

How to Make a Borax Ant Bait
Creating a borax recipe for ants is simple. Whether dealing with sugar-loving or protein-loving ants, you can mix the right ingredients at home. But remember, these are short-term fixes. Place the bait carefully, keeping it away from children and pets. If you are worried about contamination, talk to your local medical professional.
Where and How to Place the Bait
Bait placement is key to success. The bait must be easy for ants to find and carry back to the colony. Follow ant trails to get a better idea of the entry and exit points to target the treatment. Proper placement can increase the chances of eliminating the colony.
What to Expect After Setting the Bait
Don’t expect instant results when you set an ant bait. Using borax to kill ants takes a little time. But if you’re patient, you’ll notice the number of ants will start to diminish, which indicates that the colony is shrinking:
How Long Does Borax Take to Work?
You should see fewer ants within a couple of days. Depending on the size, it can take up to one week to kill the entire colony.
Signs The Colony Is Collapsing
You’ll see shorter ant trails and eventually no activity. These are good signs that the bait is working and the colony is collapsing.
Safety Tips When Using Borax
Borax is less toxic than many commercial pesticides, but it still needs to be used with care. Following safety steps can help you protect your home and your family.
Keeping Pets and Children Safe
Always place baits out of reach of children and pets. Consider using enclosed bait stations for added safety. Find out more about pet-friendly extermination tips.
Proper Storage and Cleanup
Store borax in a sealed, labeled container. Clean up spills, throw away used bait containers, and don’t leave bait out any longer than necessary.

Frequently Asked Questions
You’re likely to see fewer ants within 24–48 hours. Larger colonies may take longer to be affected, especially if bait placement is limited. It may take a week or more for the whole colony to collapse.
It depends on the ants. Observing ant behavior can help you decide whether to use a sweet or protein-based attractant, or a combination of both. Use sugar and borax for ants if they prefer sweets, or try peanut butter with borax for protein-loving species.
It can be safe when used properly. Always monitor baited areas and use enclosed containers to minimize risk. Keep bait away from children and pets, and always store materials securely.
