Can Flour Kill Ants?

Yes, flour can be an effective natural remedy to kill ants. Ants are attracted to flour due to its high carbohydrate content, but little do they know that it can be lethal for them. In this article, we will explore how flour can be used to eliminate ants and provide you with some tips on effectively using this method.

Why Use Flour to Kill Ants?

Using flour to get rid of ants is a safe and non-toxic alternative to chemical pesticides. It is particularly useful if you have pets or small children in your home, as it poses no harm to them. Additionally, flour is readily available in most households, making it a convenient solution for ant infestations.

How Does Flour Kill Ants?

When ants consume flour, it expands in their digestive system, causing them to become dehydrated and eventually die. The high carbohydrate content in flour attracts ants, making it an effective bait. Once ingested, the ants are unable to digest the flour properly, leading to their demise.

Using Flour to Eliminate Ants

Follow these steps to effectively use flour as a natural ant killer:

1. Identify the Ant Trails

Before applying flour, it is important to locate the ant trails. Ants leave behind pheromone trails, which are invisible to the human eye but guide other ants to food sources. By identifying these trails, you can target the areas where ants are most active.

2. Clean the Affected Areas

Thoroughly clean the areas where you have spotted ant activity. Ants leave behind scent trails, which can attract more ants to the same location. By removing these trails, you can disrupt their communication and prevent further infestation.

3. Apply Flour to Ant Trails

Once the area is clean, sprinkle a generous amount of flour along the ant trails and near their entry points. The flour acts as a bait, attracting the ants to consume it.

4. Monitor and Repeat

Keep an eye on the treated areas and observe the ant activity. If the flour is being consumed, it indicates that the method is working. Reapply flour as needed until the ant infestation is eliminated.

Additional Tips for Using Flour as an Ant Killer

Here are some additional tips to enhance the effectiveness of using flour to kill ants:

1. Combine Flour with Other Ingredients

Mixing flour with other substances can increase its effectiveness. For example, you can combine flour with borax or powdered sugar. Borax acts as a poison, while powdered sugar attracts ants. This combination can be more enticing to ants and lead to better results.

2. Seal Entry Points

Prevent ants from re-entering your home by sealing any cracks or gaps in windows, doors, and walls. This will help to minimize future infestations and make your ant control efforts more successful.

3. Maintain Cleanliness

Regularly clean your kitchen and other areas where food is prepared or consumed. By keeping these areas clean and free of crumbs or spills, you can discourage ants from entering your home in the first place.


In conclusion, flour can indeed kill ants effectively. Its high carbohydrate content attracts ants, but once ingested, it causes dehydration and ultimately leads to their demise. Using flour as a natural ant killer is a safe and non-toxic alternative to chemical pesticides, making it suitable for households with pets and children. By following the steps outlined in this article and implementing additional tips, you can successfully eliminate ant infestations using flour.
