Local Context

Flat Roofs and Solar Arrays North of Highway 101 Give Pigeons Cover the Streets Do Not

Pigeons (Columba livia) need a flat, sheltered ledge, and Mountain View concentrates those in North Bayshore, the district north of Highway 101 between Shoreline Boulevard and the marsh. Campus office buildings, warehouses and the loading docks off Ellis Street give a bird rooftop mechanical decks and parapet ledges the residential streets never offer. A rooftop HVAC unit is a roof over a roof. The gap underneath it is out of the wind, out of the rain and out of sight from the ground.

Solar arrays widened the problem across the whole city. The underside of a panel is a dry, shaded cavity a few inches high, which is close to ideal nesting habitat and invisible from below. Once a group settles there, droppings collect on the roof membrane and accumulating nest debris blocks drainage. That matters in Mountain View, where a year of rain arrives in one concentrated stretch between November and March rather than spread evenly across the calendar.

On the retail corridors the species mix changes. Along El Camino Real, San Antonio Road and Castro Street, house sparrows and European starlings take sign cavities, awning frames and the recessed soffits over storefront entries. The damage reads differently but the mechanism is the same: uric acid degrades roofing and finishes, nest debris blocks water, and accumulated droppings become a sanitation problem directly over a doorway or a receiving area.

How We Work in Mountain View

We survey the whole structure first, because where birds land, where they roost overnight and where they nest are usually three different places. In Mountain View that means the rooftop equipment deck, the parapet ledge, the underside of the solar array and the dock ceiling. Droppings are removed and surfaces disinfected before any hardware goes up, and active nests are handled in line with migratory bird regulations. Then we install UV-stabilized netting, stainless ledge spikes or wire as each surface calls for, anchored to hold.

Mountain View Climate

Mountain View sits mid-peninsula, warmer than San Francisco and milder than inland San Jose, with summer afternoons usually in the mid to upper 80s°F and rainfall around 14–16 inches a year. Drywood termite swarms come off in late summer and early fall, roughly August through October, and in Eichler tracts the wings usually turn up on the sill of a floor-to-ceiling window rather than in an attic nobody visits. The bay marsh at the north end keeps the air and the ground damper than the rainfall figure suggests, and morning fog reaches Shoreline far more often than it reaches the neighborhoods south of El Camino Real.

Housing Stock

Three kinds of building sit inside the same city limits and each needs a different inspection route. Old Mountain View, around Castro Street and the streets south of it, holds pre-war bungalows and a few Victorians on raised foundations, and the 1867 Rengstorff House now standing in Shoreline Park is the oldest of them. The 1950s and 1960s tracts, Monta Loma, Waverly Park, Cuernavaca, and the Sylvan Park area, are slab-on-grade, and the Eichler blocks among them are post-and-beam with exposed tongue-and-groove ceilings and radiant tubing in the concrete. Along El Camino Real and the transit corridor the stock turns to apartment and condominium buildings of every decade, which is where bed bugs and German cockroaches (Blattella germanica) actually move, unit to unit rather than in from the yard. A raised bungalow lets an inspector under the floor. An Eichler does not, and the evidence has to be read off surfaces instead.

Why Local Expertise Matters

An Eichler is not a hard house to inspect, but it is an easy house to inspect wrong. There is no attic and no crawl space, so the evidence sits on the exposed beams, the fascia, the tongue-and-groove decking, and the line where siding meets slab, and an inspector working from habit will look for access that does not exist and call the house clean. The slab has its own trap, because radiant heating tubes run inside it, and drilling for a subterranean treatment without knowing where they run turns a termite job into a plumbing repair. We work the Eichler tracts, the Castro Street bungalows, and the El Camino apartment corridor, and we write WDO reports for Santa Clara County transactions. 101 Exterminators, SPCB Lic. #9119, licensed since 2005.

Warning Signs

Signs You Need Bird Control Service in Mountain View

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 Mountain View

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

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.

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 Mountain View

Can birds under a Mountain View rooftop solar array be excluded without pulling the panels?

Yes: the standard fix is a perimeter mesh or clip system that closes the gap between the panel edge and the roof surface, installed with the array in place. The order matters: nest material and droppings under the panels are cleared and the area cleaned first, because sealing debris in leaves the drainage blockage and the sanitation issue behind the barrier. Panels stay accessible for maintenance afterward.

What does pigeon exclusion involve at a North Bayshore loading dock in Mountain View?

Dock ceilings are netted, because the birds roost on the open joists and conduit overhead where spikes have nothing to protect. We net the full ceiling bay out to the perimeter so there is no way in around an edge, then handle ledges and rooftop units separately with spikes or wire. Droppings over a receiving area are removed and the surfaces disinfected before installation, which is usually the part a food-handling facility needs documented.

Is it legal to take down a bird nest on a Mountain View building?

It depends on the species and whether the nest is active. Pigeons, European starlings and house sparrows are not protected under the Migratory Bird Treaty Act, so their nests can generally be removed. Most other species are protected, and an active nest holding eggs or young must be left until it is vacated, which is why exclusion hardware is best installed outside nesting season. We identify the species before anything comes down.

Local Pest Pressure

Common Pests We Treat in Mountain View

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

Drywood Termites

Pre-1960 and mid-century ranch homes in Mountain View's older neighborhoods have accumulated drywood termite exposure

Subterranean Termites

The Permanente Creek corridor and the high water table near Charleston Slough keep North Mountain View soils damp, and slab houses there are entered at plumbing penetrations and at the siding-to-concrete line

Roof Rats

Mature residential canopy and creek corridors support roof rat populations in Mountain View neighborhoods

Argentine Ants

Year-round pressure with seasonal peaks; particularly active in spring and fall

Bed Bugs

The apartment and condominium corridor along El Camino Real moves bed bugs between units, so treatment has to cover the neighbors as well as the reported unit
