Bird Exclusion
Bird Netting & Control in San Mateo, CA
101 Exterminators installs bird netting and control in San Mateo on rooftop equipment, loading docks, parking structures, signage and solar arrays, California licensed under SPCB Lic. #9119 since 2005. Feral pigeons (Columba livia) read the parapets and covered ledges along the Hillsdale and Bay Meadows commercial corridors the way their ancestors read a cliff face. Exclusion changes that. Scaring them does not.
Warning Signs
Signs You Need Bird Control Service in San Mateo
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 Mateo
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in San Mateo.
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 San Mateo
What actually works on pigeons at a San Mateo commercial building?
Physical exclusion works; anything that relies on startling the birds does not last. 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. Plastic owls, reflective tape and noise devices lose effect within weeks because pigeons habituate quickly. The survey determines which surfaces need which hardware.
Do pigeon droppings on a San Mateo roof cause real damage or just look bad?
They cause real damage. Uric acid breaks down roofing membrane, coatings and painted metal over time, and nesting debris blocks scuppers and roof drains. Because San Mateo concentrates nearly all of its rainfall into November through April, one blocked drain during a winter storm can put water into a building that had no leak the week before. Accumulated droppings also require protective equipment to remove safely.
Can birds be netted out from under the solar array on a San Mateo building?
Yes — the gap under a rooftop array is one of the most common spaces we close off in San Mateo. Panels create a sheltered, warm, predator-free cavity a few inches above the roof, and pigeons nest there year-round. The fix is a perimeter clip system or netting that seals the gap around the array without shading panels or requiring new penetrations through the roof membrane. Existing droppings under the array come out first.
