Bird Exclusion
Bird Netting & Control in South San Francisco, CA
101 Exterminators installs bird netting and control in South San Francisco on loading docks, rooftop equipment, parking structures, signage and solar arrays, California licensed under SPCB Lic. #9119. Feral pigeons (Columba livia) read a Lindenville warehouse parapet the way their cliff-nesting ancestors read a rock ledge. Exclusion changes that. Devices that rely on startling them do not.
Home maintenance
How do you keep pigeons from roosting on a South San Francisco building?
Remove food, nesting material and the sheltered ledges birds favor before a flock settles. Lindenville warehouses, Oyster Point campuses and Grand Avenue storefronts give pigeons beams, sign tops and equipment platforms out of the wind, and gulls from the bayfront rest on the flat roofs. Daily housekeeping and a quarterly roof walk keep birds from treating the building as home.
Keep dumpster lids shut
Pigeons and gulls stay near food. Close dumpster and compactor lids, sweep spilled product at the loading dock, and ask staff not to feed birds at outdoor break tables.
Pull nesting material before eggs appear
Clear twigs and debris from sign boxes, light fixtures, beam flanges and vent hoods as soon as you see a nest starting. Starlings and house sparrows use the small cavities pigeons can’t enter.
Close gaps above doors and canopies
Screen the space above roll-up doors and close the open ends of canopy framing. Birds pick sheltered perches out of the wind that comes through the San Bruno Gap.
Keep roof drains clear
Nest debris and droppings clog scuppers and roof drains. Clear them each fall, since nearly all of South San Francisco’s rain falls from November to March, and a blocked drain leaves water ponding on a flat roof.
Clean droppings with protection
Dried droppings can carry fungal disease. Wet buildup before scraping, wear gloves and a fitted mask, and keep cleanup away from air intakes and open doors.
When to do it
Pigeons nest year-round here; walk the roof each quarter and clear drains in October before the rains.

Warning Signs
When to Ask About Bird Netting & Control in South 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.
Visible roosting birds on parapets, window ledges, HVAC units, or signage
Accumulated droppings on roofing, vehicles, walkways, or below ledges
Nesting materials in drain gutters, vents, soffits, or under solar panels
Noise from roosting activity — particularly pigeons' cooing in early morning
Blocked drainage caused by nesting material accumulation
Health inspection violations or concerns at food-service or processing facilities
How It Works
What to Expect from Bird Netting & Control in South San Francisco
Tell us where birds perch or nest and what access is available to that part of the building. Photos can help us discuss the area that needs protection.
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.

Common Questions
Bird Netting & Control FAQs for South San Francisco
What actually stops pigeons at a Lindenville warehouse?
Physical exclusion. Netting closes a volume — a loading dock ceiling, a rooftop equipment platform, the underside of a solar array — and stainless ledge spikes or wire systems make a parapet or sign ledge unusable. Anything that depends on startling the birds loses its effect within weeks, because pigeons habituate fast, so plastic owls, reflective tape and noise devices are not a plan. The survey decides which surfaces get which hardware.
Our Oyster Point building has gulls on the roof — is that the same job as pigeons?
Same principle, different hardware and different rules. Gulls are larger, they use open flat roofs rather than sheltered ledges, and they work off the mudflats and marsh at the Colma Creek estuary, so a building near the shoreline sees different pressure than a Lindenville warehouse does. Netting an entire flat roof is rarely practical; post-and-wire systems, parapet hardware and removing what is drawing them usually are. Native and migratory birds are protected, so nest handling and timing follow those rules.
How do we clean bird droppings off a loading dock without shutting receiving down?
The cleanup is staged around your operation and done with protective equipment, not a pressure washer at lunchtime. Dried droppings can carry pathogens including Histoplasma and Cryptococcus, so the area is isolated and wetted to control dust before crews in appropriate protection clean it and exclusion hardware goes up. On a working dock off Producers Way or in Lindenville we usually run the work off-hours or bay by bay, so receiving keeps moving.
