If the ant infestation returns after using baking soda and powdered sugar, act quickly and methodically to stop reinfestation.

First, increase cleanliness everywhere ants travel by removing all food residues and storing pantry items in airtight containers to deprive them of attractants. Repeat the baking soda and powdered sugar treatment along known trails every three to four days until you see a clear decline because the method works slowly and requires persistence. Inspect and seal entry points using silicone caulk around baseboards, utility penetrations, and window frames; for gaps larger than one quarter inch use foam backer rod before caulking. Fix any moisture sources such as leaking pipes, dripping faucets, or damp crawlspaces since ants favor humid environments and moisture attracts other pests they feed on. If the colony persists despite these steps, place commercial ant baits with boric acid or other slow-acting active ingredients along trails and near nests so foraging workers take poison back to the queen and brood. Keep monitoring for two to four weeks after bait placement and rotate bait types if one formula does not reduce activity because colonies can reject baits that do not match local preferences.

Common issues are misidentifying the ant species which leads to using ineffective baits or placements so observe size, color, and trail behavior and switch bait type if you do not see worker removal within one to two weeks. Another mistake is cleaning trails too aggressively right after baiting which removes the scent cues ants use to recruit nestmates so avoid scrubbing treated trails for at least forty eight hours to keep foragers returning to the bait. A third concern is relying solely on surface treatments without fixing structure problems like gaps in weather stripping or plumbing penetrations so pair surface controls with physical exclusion and moisture repairs to stop reentry.
