Serving Crystal Springs Reservoir and surrounding areas
Hillsborough's large wooded estate lots — many directly adjacent to Crystal Springs Reservoir watershed land — create significant roof rat habitat within the city limits. Mature eucalyptus, redwood, and oak corridors provide travel routes from watershed open space directly into Upper Hillsborough estate properties. The city's older estate homes also show elevated drywood and subterranean termite activity in original redwood construction.
Common pests we treat in Hillsborough
Why Hillsborough Has Distinct Pest Pressure
Elevated wooded Peninsula estate belt — Hillsborough sits on ridgeline and canyon terrain above the Peninsula fog line at 200-400 ft elevation, with a significantly drier and sunnier microclimate than bayside Burlingame below; mature oak, eucalyptus, and redwood canopy creates a woodland pest environment across estate parcels. Annual rainfall 25 inches, concentrated November-March; significant leaf litter and organic debris accumulation, with average humidity 48-62% year-round; canyon-bottom properties above 70%.
The city's mix of housing types creates distinct pest harborage conditions:
- Period revival estate (Tudor, Spanish Colonial, Georgian, 1920s-50s)
- Mid-century modern estate (1950s-70s, Eichler-adjacent styles)
- Contemporary custom estate (1980s-2000s)
- Pre-war craftsman and colonial manor (1910s-30s)
Neighborhoods We Serve in Hillsborough
Every neighborhood has its own pest profile. Here's what our technicians find most in each area.
Estate blocks closest to Burlingame border; higher bayside moisture influence; elevated Argentine ant pressure from fog-zone adjacency.
Ridge-line estates above 350 ft; maximum eucalyptus canopy density; highest roof rat pressure in the city.
Creek-canyon-adjacent estate parcels; highest subterranean termite pressure from organic soil moisture and wood debris accumulation.
Local Pest Profile: Hillsborough
Specific facts about why these pests thrive in this microclimate — and what ATCO does about it.
Roof Rats
Hillsborough's mature eucalyptus, oak, and Monterey pine canopy across large estate parcels provides exceptional roof rat habitat. The city's extensive Spanish tile and wood shake roofs, combined with dense tree canopy touching rooflines across most properties, create ideal rat access conditions. Hillsborough consistently has the highest roof rat density on the Peninsula.
Subterranean Termites
Hillsborough's large inventory of pre-1950 estate homes — Tudor, Spanish Colonial, and colonial revival construction with original old-growth redwood framing — combined with high organic matter in estate soils and canyon-bottom moisture, creates elevated subterranean termite pressure across the city's historic housing stock.
Argentine Ants
Despite Hillsborough's drier microclimate, canyon-bottom properties and irrigated estate gardens sustain Argentine ant supercolonies. The city's extensive drip irrigation systems in ornamental gardens provide year-round soil moisture supporting large colony establishment.
Seasonal Pest Calendar for Hillsborough
Pest activity follows predictable seasonal patterns in this microclimate. Here's what to expect — and when to act.
Spring
Subterranean termite swarmers March-May in pre-1950 estate homes; Argentine ant expansion in irrigated estate gardens; roof rats breeding in mature canopy.
Summer
Roof rat activity peaks July-September in eucalyptus and pine canopy; Argentine ant foraging extends into estate kitchen areas as outdoor moisture declines.
Fall
Roof rat migration from canopy into Spanish tile and shake roofs October-November; peak rodent pressure period for Hillsborough estates.
Winter
Subterranean termite activity continues in moisture-rich canyon soils; Argentine ants retreat to deep nest locations in irrigated estate gardens.
How Hillsborough Differs From Nearby Cities
Unlike adjacent Burlingame — which has a dense urban residential character with smaller lots — Hillsborough's large estate parcels with mature woodland canopy create a fundamentally different pest profile dominated by roof rats and termites rather than Argentine ants. Hillsborough homeowners need wildlife-scale rodent management that Burlingame properties rarely require.
