Does Bleach Kill Ants? Tips for Eliminating Ant Trails


Ant trails leading into your home can be a nuisance, but there are effective ways to eliminate them. One common question is whether bleach can kill ants. In this article, we will explore various methods to clean ant scent trails and discuss the effectiveness of bleach in dealing with ants.

Understanding Ant Scent Trails

Ants rely on a trail of pheromones, natural chemicals they deposit along their routes, to guide other worker ants to food sources in your home. These trails act like breadcrumbs, leading the ants to their desired destination. To effectively eliminate ant trails, it’s crucial to remove the pheromones left by the ants.

1. Vinegar: A Natural Ant Repellent

Vinegar, a versatile household cleaner, can also help with ants. Fill a clean spray bottle with vinegar and spray it along the ant trail. Allow the vinegar to dry. However, it’s important to note that vinegar should not be used on tile grout or natural stone surfaces, as the acid content may cause damage.

2. Baking Soda: Scrubbing Paste and Dry Application

Baking soda is another effective cleaner for removing ant scent trails. You can create a scrubbing paste by mixing baking soda with water and applying it along the trail. Alternatively, sprinkle dry baking soda along the trail and in cracks and crevices.

3. Boiling Water: Outdoor Solution

Boiling water is a powerful remedy for eliminating ant trails outdoors. It can effectively wipe out the scent trails left by ants. However, it’s important to avoid using boiling water indoors for safety reasons. Consider using an electric kettle or tea kettle to carry hot water outdoors and pour it liberally over the ant trail.

4. Cinnamon: A Natural Ant Repellent

Ants have an aversion to cinnamon, making it an excellent natural repellent. Spread ground cinnamon along the ant trail, including cracks and openings. The ants will actively avoid areas with cinnamon scent, diverting them from their food-seeking path.

5. Chalk: Covering Up the Trail

Using sidewalk chalk can help cover up an ant scent trail effectively. Simply draw over the trail with the chalk and extend the coverage by several inches on both sides. This disrupts the scent trail and forces the ants to search for food elsewhere.

6. Chili Powder: A Spicy Solution

Similar to cinnamon, chili powder can serve as a cover-up for ant scent trails. Sprinkle chili powder along the trail that the ants have been using. However, exercise caution when using chili powder in areas accessible to children and pets.

7. Commercial Cleansers: Effective Alternative

If the above methods haven’t provided satisfactory results, you can try using commercial cleansers. Murphy’s oil soap or cleaners containing orange oil are known to be effective against ant scent trails. Always ensure that the cleaner you use is safe for the specific surfaces you are treating.

Does Bleach Kill Ants?

While bleach is a powerful disinfectant and cleaning agent, its effectiveness in killing ants is limited. Bleach may eliminate ants upon direct contact, but it does not eradicate the entire colony or eliminate the scent trails. Therefore, using bleach alone is not a recommended method for getting rid of ants.


To eliminate ant scent trails effectively, it’s important to disrupt the pheromone trails left by the ants. Vinegar, baking soda, boiling water (outdoors only), cinnamon, chalk, chili powder, and commercial cleansers are all viable options. While bleach may have limited effectiveness, it is not a reliable solution for eliminating ant trails. Choose the method that suits your preferences and the specific situation. By employing these¬†methods, you can successfully clean and eliminate ant scent trails in your home. Remember to prioritize safety when using any cleaning agents or hot water. By disrupting the pheromone trails, you can discourage ants from returning to your living space.

It’s important to note that prevention is key in controlling ants. Keep your home clean and free of food debris, seal off entry points, and address any moisture issues that may attract ants. Regularly inspect your property for signs of ant activity to catch infestations early.

In conclusion, while bleach may have some limited effectiveness in killing ants, it is not the most reliable solution for eliminating ant trails. By using natural remedies like vinegar, baking soda, cinnamon, chalk, and chili powder, or opting for commercial cleansers, you can effectively remove the scent trails and deter ants from your home. Remember to choose the method that aligns with your preferences and prioritize safety throughout the process.
