Identify the ant first
Sugar ants (odorous house ants) love kitchens. Carpenter ants leave frass (sawdust) near damp wood. Pavement ants nest under slabs and enter through expansion joints. The bait that works for one may be ignored by another — put out both sugar and protein bait and see which they take.
Why bait beats spray
Sprays kill workers you see. The queen keeps laying eggs. Slow baits with borax or fipronil ride back to the nest on the workers’ bodies and in shared food. Replace dried-out bait every 2–3 days.
Step-by-step plan
Follow the how-to box above. Key rule: patience. If traffic increases for 24–48 hours after baiting, it is working — recruits are following the trail to the bait.
When to call a pro
Carpenter ants in structural wood, ants after 3 weeks of correct baiting, or winged swarmers indoors in spring. A pro finds satellite nests in wall voids you cannot reach.

Bait, starve and seal ants out.
You'll need
- sugar-based ant bait stations
- protein-based bait
- caulk
- airtight containers
Tools
- flashlight
- damp cloth
-
Follow the trail
Watch where ants go at dusk. Note entry points (window frames, pipes, baseboards) and the food they visit.
-
Place baits on the trail
Put sugar and protein baits beside the trail, not on it. Do not spray insecticide nearby for 2 weeks.
-
Remove food and water
Wipe counters, seal dry goods, fix dripping taps, empty trash daily. Pet food goes in sealed bins.
-
Seal entry points
Once traffic drops, caulk cracks, fit door sweeps and trim branches touching the house.
Frequently asked questions
Why do ant sprays make it worse?
Repellent sprays split the colony (budding). Slow-acting baits let workers carry the poison back to the queen.
How long until ants disappear?
Sugar ants: 3–7 days with fresh bait. Carpenter ants or multiple colonies: 2–4 weeks.
