Serving Golden Gate Park and surrounding areas
San Francisco's diverse urban pest environment breaks down by neighborhood: the Mission District and Tenderloin see concentrated German cockroach and Norway rat activity in older multi-unit housing; the Richmond and Sunset Districts face year-round Argentine ant pressure intensified by Pacific fog moisture; and the Castro and Noe Valley's Victorian and Edwardian housing stock — much of it pre-1920 — experiences elevated drywood termite and roof rat activity in original wood framing.
Common pests we treat in San Francisco
Why San Francisco Has Distinct Pest Pressure
Oceanic — Pacific fog belt; the Sunset and Richmond are among the foggiest urban neighborhoods in North America; Mission and SOMA are noticeably warmer and sunnier. Annual rainfall 24 inches, concentrated November–March; most of the city has zero rainfall June–September, with average humidity 65–80% citywide; Sunset and Richmond above 85% on fog days; Mission 55–70%.
The city's mix of housing types creates distinct pest harborage conditions:
- Victorian (1870s–1900s)
- Edwardian (1900s–1915)
- Richmond/Sunset row houses (1920s–40s)
- Post-1906 earthquake reconstruction mixed stock
- Modern high-rise and condo (SOMA/Mission Bay)
Neighborhoods We Serve in San Francisco
Every neighborhood has its own pest profile. Here's what our technicians find most in each area.
Highest Germany cockroach and Norway rat density — dense commercial food corridors, aging plumbing, and older multi-unit stock
Year-round Argentine ant pressure from fog-driven moisture; older row house foundations with persistent dampness
Argentine ant and earwig pressure from Golden Gate Park proximity and marine fog belt
Victorian stock with drywood termite and roof rat pressure; hillside location creates wildlife-to-residential rodent corridors
Dense Victorian inventory — drywood termite swarmer flights August–October annually; Argentine ant pressure in street-tree corridors
Former industrial fill land with elevated Norway rat pressure; newer construction mitigates interior entry but utility corridors remain active
Hillside Victorian estates — drywood termite and roof rat pressure; Presidio adjacency creates wildlife corridor access
Highest Norway rat structural pressure in San Francisco — food service density and aging building stock
Local Pest Profile: San Francisco
Specific facts about why these pests thrive in this microclimate — and what ATCO does about it.
Norway Rats
San Francisco's dense sewer infrastructure — over 900 miles of combined storm-sewer lines, many dating to the 1800s — sustains one of the largest urban Norway rat populations in California. The Mission, Tenderloin, and SoMa neighborhoods have the highest structural entry pressure; underground utilities create highway-grade rat corridors directly to building foundations.
Argentine Ants
The Sunset and Richmond Districts' consistent Pacific fog — averaging 100+ fog days per year — keeps soil moisture elevated year-round, sustaining Argentine ant supercolonies in every street-tree planting strip and foundation gap. Unlike most Bay Area cities, fog prevents the late-summer moisture drop that slows ant activity elsewhere.
Drywood Termites
San Francisco's 50,000+ Victorian and Edwardian structures — the largest concentration of wood-frame pre-1920 residential buildings in the U.S. — create an enormous drywood termite opportunity. Noe Valley, the Castro, Haight-Ashbury, and Pacific Heights see annual swarmer flights August–October.
Seasonal Pest Calendar for San Francisco
Pest activity follows predictable seasonal patterns in this microclimate. Here's what to expect — and when to act.
Spring
Argentine ants emerge February–March in the Sunset and Richmond; Norway rat juveniles dispersing from established sewer colonies February–April create peak structural entry pressure.
Summer
Drywood termite swarmers peak August–October in Victorian and Edwardian neighborhoods; German cockroaches peak in Mission and Tenderloin food-service buildings during summer heat.
Fall
Rat foraging intensity increases as restaurant outdoor dining closes; roof rat activity peaks in Pacific Heights, Noe Valley, and Bernal Heights hillside properties October–December.
Winter
Norwegian rats seek indoor warmth; Argentine ants invade ahead of rain events; Sunset and Richmond see winter ant activity that rarely occurs in other Bay Area cities.
How San Francisco Differs From Nearby Cities
Unlike Daly City directly to the south — which shares San Francisco's fog belt but has primarily 1950s concrete slab construction with fewer rodent entry points — San Francisco's pre-1920 wood-frame Victorian stock creates exponentially more structural harborage. The same fog moisture that drives ant pressure in Daly City drives both ant and drywood termite pressure in San Francisco simultaneously.

Common Pests in San Francisco
San Francisco's dense housing stock, aging building foundations, and proximity to the Bay make it a hub for rats, cockroaches, bed bugs, fleas, and ants. ATCO inspects every property thoroughly and addresses root causes — entry points, harborage areas, and moisture sources — not just the surface symptoms.
