Serving San Bruno Mountain State Park and surrounding areas
San Bruno Mountain State Park's wildland-urban interface creates a direct connection between open space and residential Rollingwood and Crestmoor neighborhoods, driving active roof rat corridors from the park into residential attics and crawl spaces. The coastal fog zone and bay proximity keep Argentine ant pressure elevated year-round, and San Bruno's older residential stock provides established harborage for subterranean termites.
Common pests we treat in San Bruno
Why San Bruno Has Distinct Pest Pressure
SFO-corridor mixed — San Bruno sits directly south of San Francisco International Airport in a corridor between the Peninsula hills and the Bay; fog patterns are influenced by both the Bay and the San Bruno Gap wind corridor, creating variable humidity across the city. Annual rainfall 20 inches, concentrated November-March, with average humidity 60-74% year-round; SFO-adjacent areas near the Bay above 78%.
The city's mix of housing types creates distinct pest harborage conditions:
- Post-war Doelger-style stucco tract (1940s-50s, most city)
- Mid-century ranch (Crestmoor, 1950s-60s)
- Older craftsman and Victorian (downtown, 1910s-30s)
- Newer condos and townhomes (transit corridors, 1990s-2010s)
Neighborhoods We Serve in San Bruno
Every neighborhood has its own pest profile. Here's what our technicians find most in each area.
Hillside neighborhood bordering San Bruno Mountain; highest roof rat pressure from open space wildlife corridor.
Older commercial-residential core; craftsman-era homes with pier-and-beam construction; subterranean termite and Argentine ant pressure.
Bay-adjacent industrial-residential mix near airport; highest humidity; Argentine ant and earwig pressure dominant.
Local Pest Profile: San Bruno
Specific facts about why these pests thrive in this microclimate — and what ATCO does about it.
Argentine Ants
San Bruno's post-war tract housing — stucco-over-wood-frame construction similar to Daly City's Doelger stock — creates continuous shared-foundation pathways for Argentine ant supercolony expansion. The city's SFO-corridor humidity sustains colonies year-round, with minimal winter pressure reduction.
Roof Rats
San Bruno's hillside neighborhoods border the San Bruno Mountain State Park wildlife corridor to the north and the San Andreas Lake watershed to the south, providing substantial roof rat habitat. Crestmoor hillside properties face the highest rat pressure from open space adjacency.
Earwigs
San Bruno's consistent coastal humidity and dense ornamental landscaping in post-war residential tracts sustain earwig populations citywide. Fog-zone soil moisture maintains earwig activity through summer without the usual dry-season decline seen in inland cities.
Seasonal Pest Calendar for San Bruno
Pest activity follows predictable seasonal patterns in this microclimate. Here's what to expect — and when to act.
Spring
Argentine ant expansion in post-war tract neighborhoods March-May; earwig emergence in landscaped gardens across the city.
Summer
Argentine ant and earwig pressure continues with SFO corridor humidity; roof rats active in San Bruno Mountain and San Andreas watershed canopy.
Fall
Roof rat migration from San Bruno Mountain into Crestmoor hillside structures October-November; significant rodent pressure period.
Winter
Argentine ant colonies remain active in fog-moistened tract foundations; earwigs persist in mulched garden beds year-round.
How San Bruno Differs From Nearby Cities
Unlike neighboring Millbrae — which has a more varied topography with a clearer hillside/flatland distinction — San Bruno's pest pressure is more uniformly driven by its post-war tract housing stock across the city. Both cities share roof rat pressure from open space, but San Bruno's Doelger-style construction creates a city-wide Argentine ant vulnerability more similar to Daly City than Millbrae.
