How Long Does Baking Soda Take To Kill Ants

Ant infestations are a common nuisance in households, prompting homeowners to seek effective and eco-friendly solutions for pest control. Baking soda has emerged as a popular remedy for tackling ant problems due to its non-toxic nature. But how long does baking soda take to kill ants, and is it truly effective? In this comprehensive guide, we delve into the science behind baking soda’s ant-killing properties, its preparation and application, factors influencing its efficacy, safety considerations, and real-life experiences. By the end, you’ll have a clear understanding of baking soda’s potential as a natural ant killer.

How Long Does Baking Soda Take To Kill Ants? 

The time it takes for baking soda to kill ants can vary depending on factors such as ant species, bait placement, and nest size. In some cases, it may take a few days to a week for the baking soda to eliminate the ant colony.

How Does Baking Soda Kill Ants? 

Baking soda, also known as sodium bicarbonate, is an effective ant killer due to its alkaline nature. When ants consume baking soda, it reacts with the acidic digestive enzymes in their bodies, causing a release of carbon dioxide gas. As ants are unable to expel excess gas, it accumulates within their digestive systems, leading to their eventual demise. Additionally, the alkaline properties of baking soda disrupt the balance of acid within the ant’s body, further contributing to its death.

Furthermore, the small, abrasive particles of baking soda can damage the outer protective layer of an ant’s exoskeleton. This damage compromises the ant’s ability to retain moisture and can lead to dehydration, further hastening its demise. Baking soda is particularly effective when used as bait, mixed with a sweet substance that attracts ants. The workers carry the bait back to their nests, where it is shared with other colony members, resulting in a domino effect that eventually eradicates the entire ant population.

It is essential to use caution when using baking soda as an ant killer, especially around children and pets. Although it is a safer alternative to chemical pesticides, it should be placed strategically and not used in excessive quantities to avoid unintended harm to other non-target organisms.

Why Baking Soda Is A Safe And Eco-Friendly Alternative To Chemical Ant Killers? 

Baking soda is considered a safe and eco-friendly alternative to chemical ant killers for several reasons:

  • Non-toxic to humans and pets: Unlike chemical pesticides, baking soda is non-toxic and poses minimal risks to humans and animals. It is safe to use in areas frequented by children and pets, making it a family-friendly ant control option.
  • Biodegradable: Baking soda is a natural compound that readily breaks down into harmless substances like water and carbon dioxide. It doesn’t persist in the environment or contribute to long-term pollution, reducing its impact on ecosystems.
  • Minimal environmental impact: Chemical ant killers often contain harmful ingredients that can harm beneficial insects, wildlife, and plants. Baking soda, on the other hand, has a low environmental impact, making it a more sustainable choice for pest control.
  • Affordable and readily available: Baking soda is widely available and cost-effective compared to commercial chemical ant killers, making it accessible to a broader range of consumers.
  • Effective for specific ant species: While baking soda may not be a one-size-fits-all solution for all ant species, it can be highly effective against certain types of ants, especially when used in combination with attractive baits.
  • Promotes responsible pest management: Opting for eco-friendly alternatives like baking soda encourages a shift towards more sustainable and responsible pest management practices, promoting a healthier environment for both humans and nature.

Factors Affecting The Efficacy Of Baking Soda As An Ant Killer

The efficacy of baking soda as an ant killer can be influenced by several factors:

  1. Ant Species: Different ant species may react differently to baking soda bait. Some species may be more attracted to the bait, while others might show little interest, affecting the overall effectiveness of the treatment.
  2. Bait Formulation: The bait’s attractiveness and palatability play a significant role in how well ants are lured to consume the baking soda. Mixing baking soda with sweet substances like sugar or honey can enhance its appeal to foraging ants.
  3. Nest Size and Location: The size of the ant colony and the location of their nest can impact how quickly the baking soda treatment eliminates the infestation. Larger colonies with multiple nesting sites might take longer to eradicate fully.
  4. Environmental Conditions: Temperature, humidity, and other environmental factors can influence ant activity and behavior. Ants might be more active and responsive to bait during certain seasons or weather conditions.
  5. Bait Placement: Strategic placement of the bait is crucial for attracting ants and ensuring they carry the baking soda back to their nests to share with the colony. Properly locating the bait along ant trails and entry points improves its effectiveness.
  6. Colony Behavior: Some ant colonies may exhibit bait aversion, where they avoid consuming the bait after detecting potential threats. This behavior can reduce the effectiveness of baking soda as an ant killer.
  7. Persistence and Patience: Baking soda may not yield immediate results, requiring persistence and patience. It might take a few days to a week or more to see a noticeable reduction in ant activity.
  8. Concurrent Use of Other Food Sources: If ants have access to alternative food sources, they may ignore the baking soda bait, hampering its ability to control the colony.
  9. Chemical Interference: In some cases, the presence of residual chemical pesticides or cleaners near the bait area might deter ants from consuming the baking soda.

Tips On Placing Bait Strategically For Maximum Impact

Strategic placement of bait is crucial to maximize the impact of baking soda as an ant killer. Here are some tips to help you place the bait effectively:

  • Identify Ant Trails and Entry Points: Observe ant movement patterns and locate their trails and entry points into your home. Place the bait directly along these trails to ensure a higher chance of attracting foraging ants.
  • Use Multiple Bait Stations: Rather than relying on a single bait station, use multiple ones to cover different areas where ant activity is prominent. This increases the likelihood of ants encountering the bait.
  • Keep Bait Away from Chemicals: Avoid placing the bait near areas treated with chemical pesticides or strong cleaners, as these can repel ants and reduce the effectiveness of the baking soda bait.
  • Opt for Attractive Bait Mixtures: Mix baking soda with sweet substances like sugar, honey, or jam to make the bait more appealing to ants. This encourages them to consume it and share it with the colony.
  • Protect Bait from Rain and Moisture: Ensure the bait remains dry and accessible by placing it in covered containers or under sheltered areas. Moisture can reduce the bait’s effectiveness and make it less appealing to ants.
  • Place Bait Near Nesting Sites: If you can identify the ant colony’s nesting area, place the bait as close to it as possible. This increases the chances of worker ants finding and carrying the bait back to the nest.
  • Monitor and Refresh Bait Regularly: Check the bait stations regularly to see if the ants are consuming the bait. If the bait is depleted or appears less attractive, replace it with a fresh batch.
  • Be Patient: Baking soda may take time to work, especially for larger ant colonies. Be patient and allow sufficient time for the ants to share the bait with their colony members.
  • Keep Bait Out of Reach of Children and Pets: Ensure that the bait is placed in areas inaccessible to children and pets to prevent accidental ingestion.
  • Combine Baking Soda with Other Remedies: For stubborn ant infestations, consider combining baking soda with other natural ant deterrents, such as diatomaceous earth or essential oils, to enhance the overall effectiveness of your ant control efforts.


In conclusion, baking soda proves to be a safe, eco-friendly, and effective alternative for controlling ants in households. Its alkaline properties disrupt digestive systems, leading to their demise without harming humans or pets. While its efficacy depends on various factors, strategic bait placement and patience are key. Embracing baking soda as an ant killer promotes responsible pest management and a healthier environment for all.
