Bird Netting & Control in San Francisco, CA

Roosting Prevention · Netting · Spikes · Structural Protection

Bird roosting and nesting on structures causes real, measurable damage: uric acid in droppings degrades roofing materials, blocking materials with nesting debris accelerates water intrusion, and accumulated droppings carry pathogens including Histoplasma and Cryptococcus. 101 Exterminators installs professional-grade exclusion systems — netting, ledge spikes, wire deterrents, and slope hardware — that prevent roosting without harming birds.. Serving San Francisco and surrounding San Francisco County.

Why San Francisco Homes Need Bird Control Services

Pigeon populations in Salinas, Monterey, Santa Cruz, and San Jose are substantial — urban food sources and human structures provide ideal roosting habitat. Agricultural facilities in Monterey and San Benito counties face significant starling and house sparrow pressure during harvest. Warehouses, distribution centers, and processing facilities in Santa Clara County require bird exclusion as a food-safety compliance measure.

Drywood termites in pre-1940 framing are the dominant concern. Subterranean termites active in fog-belt soil. Real estate transaction volume is among the highest in California — WDO inspections are a routine part of every property sale. Swarm season May–October for drywood; February–April for subterranean.

San Francisco Climate

San Francisco's marine climate — persistent fog, moderate temperatures, and year-round mild humidity — supports continuous termite colony activity without winter dormancy. Western neighborhoods (Sunset, Richmond) stay foggy and moist; eastern neighborhoods (Mission, Castro, Noe Valley) are warmer, favoring drywood termite swarm activity May–October.

Housing Stock

The city has approximately 20,000+ pre-1915 Victorian and Edwardian structures, many with original old-growth redwood and fir framing never comprehensively treated for termites. Row house configurations — where buildings share party walls — allow colony spread without typical swarming evidence. Post-1906 and post-WWII construction have separate but significant termite vulnerabilities.

Why Local Expertise Matters

San Francisco termite work is a specialty. Row house fumigation logistics, the city's pesticide ordinances, historic building treatment constraints, and the specific WDO reporting format expected by SF real estate agents all require local expertise. We hold SPCB License #9119 and have direct experience with these city-specific factors.

Our Bird Control Process in San Francisco

Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in San Francisco.

01

Survey & Pressure Assessment

We document all roosting and nesting locations, species present, and the structural and sanitary conditions created. We assess approach points and preferred perching locations.

02

Sanitation & Nest Removal

Before installing exclusion hardware, accumulated droppings are removed and affected surfaces are disinfected. Active nests are removed in compliance with migratory bird regulations.

03

Exclusion Installation

Netting, spikes, wire, or other deterrents are professionally installed and anchored to prevent bird access to treated areas. Installations are designed for long life and aesthetic integration with the structure.

04

Monitoring & Maintenance

For commercial facilities, we offer periodic inspection to confirm exclusion integrity and address any gaps created by maintenance activities or structural changes.

Bird Netting & Control FAQs for San Francisco

Is bird control legal in California?

Excluding birds from roosting on structures is fully legal. However, federal and California law prohibit disturbing active nests containing eggs or chicks of native migratory species (including swallows and house sparrows in some contexts). We follow all applicable regulations, including timing nest removal to inactive periods.

How long does bird netting last?

Commercial-grade UV-stabilized polyethylene bird netting has a typical lifespan of 10 years or more in exterior applications. Stainless steel spike systems last 15+ years. Longevity depends on installation quality and maintenance.
