Ants: Identify the Species, Stop the Trail, Choose the Right Treatment
Ants are one of the most persistent pests in US homes. A single worker on the counter is often a scout from a colony hidden in a wall, under a slab, in damp wood, or outside near the foundation. Start here: identify the ant type, match the treatment to the situation, then jump into the detailed guide that fits your problem.

What is the best first step for ants in the kitchen?
Start with bait along the active trail, then clean food residue and seal entry points after activity drops. Spraying the trail first can repel ants away from bait and reduce colony-level control.
Why do I see more ants after placing bait?
That often means the bait has been found. Workers gather, feed, and carry the bait back toward the colony. Activity may increase for a short period before it declines.
When are carpenter ants more serious than ordinary house ants?
Large dark ants near damp wood, sawdust-like debris, soft wood, wall sounds, or activity around leaks can point to carpenter ants. They do not eat wood like termites, but they can excavate damaged wood for nesting.
Should I treat fire ant mounds one at a time?
For repeated fire-ant mounds, a yard-wide bait strategy usually works better than chasing one mound at a time. Remaining active mounds can then be spot-treated according to the label.
How do I keep ants from coming back?
Remove food and water sources, wipe scent trails, seal gaps around doors and windows, trim branches touching the house, keep mulch and wood away from siding, and reduce moisture around the foundation.
