Ant infestations can turn your home into a battleground, with those tiny invaders marching across countertops and floors in search of crumbs and sweets. If you’re dealing with ants and looking for a simple, household solution, you’ve likely wondered: can baking soda kill ants? This common kitchen staple is often touted as a natural ant killer, but does it really work? In this guide from On Demand Pest Control, we’ll dive into the science, share effective DIY methods, weigh the pros and cons, and explain when it’s time to call in the pros for lasting relief.
Key Takeaways on Using Baking Soda for Ant Control
- Baking soda can kill ants when ingested, disrupting their internal systems and potentially wiping out colonies.
- It’s a safe, non-toxic option for homes with kids and pets, but results can vary based on ant species and infestation size.
- Mix it with attractants like sugar for best results—ants carry it back to the nest for maximum impact.
- For stubborn or large infestations, professional pest control is often more reliable and efficient.
Does Baking Soda Really Kill Ants?
Yes, baking soda can kill ants, but it’s not a guaranteed miracle cure. Sodium bicarbonate (the scientific name for baking soda) works as an ant killer primarily when ants ingest it. Once inside their bodies, it reacts with the acidic environment of their stomachs to produce carbon dioxide gas. This gas buildup can cause bloating, internal disruption, and eventual death.
However, effectiveness depends on several factors:
- Ant Behavior: Ants are social insects that forage for food and share it with the colony via pheromone trails. If they consume baking soda-laced bait and transport it back to the nest, it can target the queen and workers, leading to colony collapse.
- Species Variations: It may work better on sugar-seeking ants like Argentine or carpenter ants, but less so on grease-loving species or aggressive ones like fire ants.
- Limitations: Ants might detect and avoid the bait after initial exposure, making it inconsistent for heavy infestations. Expert pest technicians note that while it has some impact, it’s not as potent or reliable as commercial baits.
In short, baking soda is a solid DIY option for minor ant problems, but don’t expect overnight results—patience is key.
How Does Baking Soda Kill Ants? The Science Explained
Ants maintain a delicate pH balance in their digestive systems. Baking soda, being alkaline, throws this off when ingested, leading to fatal disruptions. Additionally, the CO2 reaction can cause physical damage, similar to how it fizzes in vinegar.
To make it effective:
- Ants must be lured to the baking soda using something sweet or appealing.
- Place baits along trails where ants are active—kitchens, entry points, or outdoor nests.
- Avoid using it alone; plain baking soda repels ants rather than attracting them.
This method leverages ants’ natural foraging habits, turning their strength (teamwork) into a weakness.
DIY Baking Soda Ant Killer Recipes and Methods
Ready to try it yourself? Here are simple, step-by-step recipes using everyday items. These are borax-free for added safety around pets and children.
Basic Baking Soda and Sugar Bait
- Ingredients: 1 part baking soda, 1 part powdered sugar.
- Instructions:
- Mix thoroughly in a bowl.
- Sprinkle small amounts near ant trails, entry points, or nests.
- Ants are drawn to the sugar, ingest the mix, and share it with the colony.
- Tip: Use shallow lids or cotton balls for easy placement and cleanup.
Enhanced Bait for Different Ant Types
- For Sweet-Seeking Ants (e.g., Sugar Ants): Add a teaspoon of honey or corn syrup to the basic mix for a sticky consistency. This boosts attraction for species like pavement ants.
- For Protein-Loving Ants (e.g., Fire Ants): Blend baking soda with peanut butter instead of sugar. Apply in small dabs.
- Peppermint Boost: Mix in a few drops of peppermint essential oil to disrupt scent trails while the bait does its work.
Spot Treatment with Baking Soda and Vinegar
- Ingredients: Equal parts baking soda and white vinegar.
- Instructions: Sprinkle baking soda on ants or trails, then spray vinegar over it. The fizzing reaction releases CO2 on contact, killing ants instantly—but this is for visible ants only, not colonies.
For outdoor use, sprinkle sparingly around garden beds or foundations, but avoid plants as it can alter soil pH.
Pros and Cons of Using Baking Soda to Kill Ants
Like any remedy, baking soda has its strengths and drawbacks.
Pros
- Natural and Safe: Low toxicity compared to chemical sprays; pet- and child-friendly when used properly.
- Affordable and Accessible: Made from household staples—no need for store runs.
- Targets Colonies: When baited correctly, it can eliminate the source, not just foragers.
- Eco-Friendly: Breaks down harmlessly without environmental harm.
Cons
- Inconsistent Results: Ants may avoid it after detecting deaths, limiting long-term control.
- Slow-Acting: It can take days or weeks to see full effects, allowing infestations to worsen.
- Not for All Ants: Less effective against large colonies or species like fire ants.
- Messy Application: Powder can scatter, and overuse might affect non-target insects or soil.
Alternatives to Baking Soda for Ant Control
If baking soda doesn’t cut it, try these other natural options:
- Diatomaceous Earth: A powdery substance that dehydrates ants by damaging their exoskeletons. Sprinkle along trails for a barrier effect.
- Vinegar Solutions: Mix equal parts vinegar and water to spray on trails—it erases pheromones but doesn’t kill on contact.
- Boric Acid Baits: Similar to baking soda but more potent (use cautiously due to higher toxicity).
- Essential Oils: Lemon, tea tree, or peppermint oils repel ants when diluted and sprayed.
- Professional Products: For severe cases, over-the-counter gels or our expert-recommended treatments offer faster results.
Always test small areas first to avoid damage to surfaces.

Frequently Asked Questions About Baking Soda and Ants
Yes, but use it sparingly around nests or trails. It works best in dry conditions and may need reapplication after rain.
Typically 24-48 hours for individual ants, but up to a week or more for colony elimination as the bait spreads.
In small amounts, yes—it’s non-toxic. However, keep pets away from baits to prevent ingestion of large quantities.
It can have some effect if mixed with attractants, but fire ants are aggressive and often require professional intervention.
While effective, this increases toxicity. Stick to borax-free options for safer use, or consult a pro.
Ants might be avoiding the bait or the infestation is too advanced. Try alternatives or call On Demand Pest Control for expert help.
