Carpenter ants hollow out damp or damaged wood rather than eating it, which means their presence often signals a moisture problem worth investigating too. Every Ant Control call in San Francisco starts with tracing the trail's direction rather than guessing, which is what keeps us from treating the wrong side of the colony.
We trace visible trails back toward the nest and identify the species before recommending bait or barrier treatment.


Every technician treating San Francisco properties for ants carries state licensing and full liability coverage.
Ant calls get same-day scheduling in most cases, since trails often mean a colony has already found a reliable food source.
Pricing is quoted flat after inspection, covering both interior bait placement and exterior perimeter treatment.
We use non-repellent insecticide and slow-acting bait so the colony carries product back to the nest instead of scattering.
We trace frass (wood shavings) piles back to the actual nest location, often inside a wall void or damaged sill plate.
Odorous house ants form large, fast-moving colonies with multiple satellite nests, so bait placement targets several access points at once.
We treat expansion joints and slab edges directly, which is where pavement ant colonies typically establish.
We prioritize fire ant calls in yards with kids or pets given the sting risk from disturbed mounds.
Commercial accounts get documented service visits with bait station placement suited to kitchen and retail environments.
We reapply perimeter barrier on a recurring schedule to keep new ant activity from re-establishing.

Call +1-844-564-2570 and describe the trail location — kitchen counter, foundation, or yard mound — for the right San Francisco dispatch.
Our mobile units stock separate bait types for carpenter, odorous house, pavement, and fire ants.
Inspection includes checking for carpenter ant frass and moisture issues alongside standard trail mapping.
Bait and barrier treatment go down the same visit, with a follow-up to confirm the colony has been eliminated.
We'd sprayed the visible trail ourselves for months with no luck. Non-repellent bait cleared the whole colony within two weeks.
Fire ant mounds near our kids' swing set got treated same-day, which was a huge relief given how close they'd built to the play area.
Having a documented ant program helped us pass our last health inspection without issue.
Pavement ants kept coming up through a crack in our patio slab every summer until the perimeter treatment finally sealed that off for good.

Surface spray kills visible ants but rarely reaches the actual nest, so the trail usually returns within days.
Carpenter ants prefer damp or already-damaged wood, so their presence sometimes points to a moisture issue worth checking.
Yes, when placed correctly by a technician, bait stations are designed to keep product contained and inaccessible.
Most trails noticeably decline within one to two weeks as the bait works through the colony.
Fire ants are treated with both immediate mound knockdown and a longer-acting yard-wide approach.
Commercial ant programs include documented visits so you have records ready for any health inspection.
