Baking soda mixed with powdered sugar kills ants because the sugar lures them to eat and the baking soda reacts inside their digestive system to create lethal gas pressure.

When ants consume a mixture of baking soda and powdered sugar the sugar acts as an attractant and the baking soda passes into their gut where it meets acidic digestive juices; that acid triggers a chemical reaction that produces carbon dioxide gas which the ant cannot expel efficiently. The trapped gas increases internal pressure and disrupts cellular and organ function leading to rapid physiological collapse. To prepare an effective bait mix weigh one part baking soda to one part powdered sugar and keep it dry so it does not prematurely react; place small amounts on index cards or inside shallow containers along ant trails and replace every one to two days to maintain attractiveness. Avoid using water because moisture will activate the baking soda outside the ant and reduce ingestion; if humidity is high, use slightly less baking soda relative to sugar so the texture remains powdery. Keep the bait away from pets and children and monitor trail activity to confirm uptake before removing other controls so the treated ants can carry particles back to the nest. For persistent infestations combine this baiting approach with sanitation to remove other food sources and seal entry points to prevent new foragers from replacing the exposed colony members.

Common mistakes include using too much baking soda which makes the bait unpleasant so ants ignore it; fix this by sticking to a balanced one to one ratio and testing small placements. Another error is placing bait where it gets wet which triggers the reaction prematurely and leaves little for ants to eat; move baits under cover or in dry indoor locations and refresh them daily in damp conditions. A third concern is expecting instant colony elimination because the method requires worker ants to carry particles back to the nest; be patient, continue baiting for at least one to two weeks and combine with nest-sealing and sanitation for long term control.
