Bird Exclusion

Bird Netting & Control in Berkeley, CA

101 Exterminators installs bird netting in Berkeley for commercial buildings, mixed-use properties, and homes with rooftop solar. Pigeons (Columba livia), house sparrows, and European starlings roost on the awnings, parapets, and signage along Shattuck Avenue, University Avenue, and Fourth Street, and under residential solar arrays across the city. We exclude birds from the structure rather than harming them. SPCB Lic. #9119, since 2005.

Local Context

Pigeons Read a Berkeley Storefront as a Cliff Face

Rock pigeons evolved on sea cliffs, and a Berkeley commercial block is a very good imitation of one. The older storefronts along Shattuck, University, Telegraph, and San Pablo Avenue offer projecting cornices, sign bands, transom ledges, and recessed entries — flat, sheltered surfaces at height with clear approach lines. Add downtown parking structures and the loading areas behind Fourth Street retail and you have year-round roosting habitat with a reliable food supply from foot traffic below.

The damage is not just droppings on the sidewalk. Uric acid degrades painted metal, awning fabric, and roofing membrane over time, and nesting debris packed into a scupper or gutter is a common cause of water backing up into a Berkeley building with a low-slope roof. Accumulated droppings in an enclosed roost — a parking structure ceiling, a loading dock canopy — also become a sanitation and cleanup problem that grows quietly until someone has to pay for remediation.

Residential Berkeley has its own version. Rooftop solar arrays create a warm, hidden cavity a few inches above the roof deck, and pigeons and starlings move straight into it, then nest against the panel wiring and along the racking. On the hillside blocks where roofs are steep and access is awkward, that gap is invisible from the ground and only shows up as scratching overhead, staining down the fascia, and debris in the gutter.

How We Work in Berkeley

We survey the roost before we install anything: which species, which ledges, which approach lines, and how much droppings buildup has to come out first. On a Berkeley storefront we usually net the recessed entry or the sign band and put stainless ledge spikes on the cornice and transom ledges. On a residential solar array we clean the cavity and clip a rigid mesh skirt around the panel perimeter. Nest removal follows migratory bird regulations, and hardware is anchored to last through the winter storms.

Berkeley Climate

Berkeley's climate transitions from the foggy flatlands near the Bay to the warmer, drier hillside neighborhoods above the UC campus. The flats receive more marine fog, supporting subterranean termite activity in moist soils. The hills and hillside neighborhoods are warmer and drier — ideal drywood termite territory, with swarms active roughly August through October. Annual rainfall averages 22–25 inches in the hills.

Housing Stock

Berkeley reads as one old city but inspects as three. The pre-1923 brown shingle and Craftsman stock south of campus is the classic case: old-growth Douglas fir and redwood framing, shingle siding laid over sheathing with gaps behind it, and in many houses no record of a comprehensive termite treatment in living memory. The 1923 fire rebuild north of campus produced a distinct mid-1920s layer, stucco over wood frame, where the exterior gives away far less at a glance and the framing has to be reached through the attic and the crawl space. Everything west toward the Bay and south past Ashby is a mix of pre-war cottages and post-war infill. Across all three, the recurring complication is subdivision. Single-family houses turned into duplexes, triplexes, and rented flats decades ago, and the shared attics, common walls, and stacked plumbing chases that came with those conversions are the routes colonies and rodents use between units.

Why Local Expertise Matters

A Berkeley inspection is mostly a question of getting to the wood. Brown shingle siding hides the sheathing behind it, the 1920s stucco rebuild north of campus hides more, and a house divided into three flats has attic and subfloor spaces that no single occupant has looked at in years. We inspect for what the construction era predicts rather than what is visible from the sidewalk, we write findings so an owner, a tenant, and an agent can all read the same report and agree on what it says, and we talk through treatment options, including the least-toxic ones, before anything is scheduled.

Warning Signs

Signs You Need Bird Control Service in Berkeley

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

Our Bird Control Process in Berkeley

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

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.

Why 101 Exterminators

Bird Control You Can Count On in Berkeley

Permanent Exclusion

Netting and spike systems provide lasting exclusion that doesn't require repeated chemical applications or frightening devices that birds habituate to.

Commercial Compliance

Our installations meet food-safety standards for facilities subject to USDA, FDA, or health department inspection.

Droppings Cleanup Included

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 Berkeley

How do I keep pigeons off the awnings and signage of a Shattuck Avenue storefront?

Exclusion hardware, matched to the surface. Flat cornices, sign bands, and transom ledges take stainless steel ledge spikes; recessed entries, alcoves, and open soffits take netting tensioned across the opening so birds cannot get behind it. Existing droppings and nesting material are removed and the surfaces disinfected first, because leaving the scent and the nest in place keeps the pressure on. Deterrent gels and plastic owls do not hold on a Berkeley commercial block.

Birds are nesting under my Berkeley rooftop solar panels — what stops that?

A rigid mesh skirt clipped around the perimeter of the array closes the gap between the panels and the roof deck, which is the cavity they are using. The sequence matters: nests and droppings come out and the area is cleaned first, then the mesh goes on, or you seal birds and nesting debris under the panels. On the steeper Berkeley hillside roofs this is fall-protection work, so it is not a weekend project.

Can bird nests be removed from a Berkeley building at any time of year?

No — active nests of most native species are protected under federal migratory bird regulations, so timing is a real constraint. Pigeons, house sparrows, and European starlings are not protected in the same way, which is why they can be addressed on a normal schedule. We identify the species during the survey and, when a protected active nest is present, we plan the exclusion work for after the young have fledged.

Local Pest Pressure

Common Pests We Treat in Berkeley

Every area has its own pest profile shaped by climate, housing, and geography. These are the pests we see and treat most often in Berkeley — tap any one to learn how to identify it and what treatment involves.

Drywood Termites

Berkeley's pre-1930 Craftsman, brown shingle, and Edwardian homes have 100-year-old Douglas fir framing with extensive drywood termite infestation histories

Subterranean Termites

Flatland and creek-adjacent neighborhoods maintain soil moisture supporting active subterranean termite colonies

Roof Rats

Dense urban tree canopy — fruit trees, mature oaks, and ornamentals — supports a large endemic roof rat population across Berkeley

Argentine Ants

Supercolony pressure throughout all Berkeley neighborhoods with consistent spring and fall indoor invasions

Dampwood Termites

Hillside structures with drainage issues and fog-belt homes with crawl space moisture can have dampwood termite activity
