Powdered sugar mixed with baking soda can control ants but it can also attract other pests if not used carefully.

When you mix powdered sugar and baking soda for ant control, use a single teaspoon of powdered sugar to one teaspoon of baking soda and place it only where ants are actively traveling, not in open areas. The sugar lures the ants while the baking soda reacts with their stomach acid and causes internal disruption, but the effect can take one to three days so be patient and avoid disturbing the trail. Apply the mixture in very small, discrete bait points on cardboard or scrap paper so you can remove any leftovers easily and prevent spillover that attracts flies, roaches, or other sugar feeders. Monitor those bait points daily and replace them only when they are gone or visibly contaminated, and clean the area with warm water and mild soap before placing new bait to remove pheromone trails. If you have pets or children, keep baits out of reach and consider using homemade bait inside sealed containers with a small dispensing hole to limit access. For larger or persistent infestations, combine targeted baits with sanitation, sealing entry points, and removing food and moisture sources rather than increasing the amount of sugar bait.

The most common mistake is leaving large amounts of the sugar mixture out which invites non target insects; fix that by limiting each bait to a pea sized amount and picking up excess as soon as ants stop feeding. Another frequent issue is placing bait on a dirty surface that repels ants or masks the scent; solve this by cleaning the placement area first and setting the bait on a clean card or bottle cap. People also assume it will work instantly and overuse it, which can lead to secondary pests; avoid this by using small, monitored applications and integrating sanitation and exclusion so you are not relying solely on sugar bait.
