Bird Exclusion
Bird Netting & Control in San Francisco, CA
101 Exterminators installs bird netting and exclusion in San Francisco for commercial buildings, storefronts and older residential blocks, licensed under SPCB Lic. #9119 since 2005. A pigeon reads an ornamental Edwardian cornice the way it reads a cliff ledge: a sheltered horizontal surface with open air in front of it. This city built thousands of them. Exclusion hardware keeps birds off the ledge without harming them.
Warning Signs
Signs You Need Bird Control Service in San Francisco
We install heavy-duty UV-stabilized bird netting to exclude birds from rooftop HVAC areas, loading dock ceilings, solar array undersides, and decorative architectural features. Stainless steel ledge spikes are installed on parapet walls, window ledges, signage, and other flat roosting surfaces. Electric deterrent systems, wire systems, and slope hardware are available for specific applications. We also remove active nests and clean up accumulated droppings with appropriate biosafety precautions.

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

Accumulated droppings are removed and surfaces are disinfected prior to exclusion installation — not just hardware on top of existing contamination.
Common Questions
Bird Netting & Control FAQs for San Francisco
How do you keep pigeons off a decorative cornice without damaging the building?
The hardware is chosen for the surface. On ornamental cornices we generally use netting tensioned on a cable frame, or angled slope hardware, so fixings land in mortar joints or existing fasteners rather than historic woodwork. Stainless spikes suit flat parapets, sills and signage instead. The survey covers the full façade first, because a bird pushed off one ledge simply takes the next one along the same wall.
Do pigeons on a San Francisco restaurant roof create a health inspection problem?
Yes — roosting over a back door, a receiving area or rooftop kitchen exhaust is a documented sanitation issue and gets cited. Restaurants along Mission Street, Columbus Avenue and Clement Street sit in dense blocks where one flock works several rooftops at once, so the birds on your roof may be feeding two doors down. Exclusion plus a cleaned and disinfected surface is what closes the finding, and we document the work for your inspection file.
Can bird droppings really damage a San Francisco roof?
They can, in two ways. Droppings are acidic and degrade painted wood ornament, galvanized flashing and older roof membrane over time. The larger risk is drainage — nesting debris blocks scuppers and roof drains, and this city takes most of its rainfall in a concentrated stretch from December through March. A flat roof in SoMa or Mission Bay with a plugged drain turns a roosting problem into a leak.
