Santa Clara County Pest Control — Urban to Agricultural

German cockroaches are endemic in commercial food service throughout San Jose. Norway rats are a year-round urban pest near food establishments, markets, and storm drain infrastructure. Argentine ants are pervasive throughout residential and commercial areas. Drywood termites are active in older neighborhoods. Bed bugs circulate in multi-family housing and hotels.

Drywood termites are the dominant structural pest concern — the density of 1950s–1970s wood-frame homes means a large percentage of older Sunnyvale properties have active or historic drywood termite activity. German cockroaches are endemic in the commercial food service corridor along Murphy Avenue and in tech campus cafeteria facilities. Argentine ants are pervasive in residential areas with predictable spring and fall indoor invasions. Norway rats use the creek drainage infrastructure to move through the city.

German cockroaches are endemic in the commercial food service infrastructure throughout Santa Clara — the combination of tech company cafeterias, Levi's Stadium food operations, and dense restaurant corridors creates year-round commercial cockroach pressure. Norway rats use the Guadalupe River and storm drain infrastructure extensively. Drywood termites are active in older residential neighborhoods, particularly the Old Quad and older Berryessa-adjacent areas.

Drywood termites in older residential neighborhoods; subterranean termites in bay-adjacent and creek-adjacent northern Mountain View. Active Silicon Valley real estate market drives consistent WDO inspection demand throughout the year.

Drywood termites in older inland housing; subterranean termites in Bay-adjacent and creek-adjacent western and central Milpitas. Active South Bay real estate market near BART drives consistent WDO inspection demand.

Drywood termites in 1960s–1980s ranch homes across the city — the dominant concern. Subterranean termites near creek corridors and in the valley floor. Cupertino's high-value, high-turnover real estate market makes WDO inspection thoroughness critical.

Drywood termites are active throughout the older neighborhoods near downtown and throughout the 1950s–1980s suburban grid. Norway rats are a year-round concern along the Los Gatos Creek corridor — properties within two blocks of the creek see consistently higher rodent pressure than those farther away. Argentine ants are pervasive throughout the city. German cockroaches are active in the downtown restaurant concentration on Campbell Avenue.

The mountain edge creates persistent roof rat pressure in hillside neighborhoods — unlike the flat Silicon Valley cities where rats primarily use storm drain infrastructure, Los Gatos hill properties face arboreal rat pressure from the mountain-forest canopy. Victorian downtown homes have drywood termite histories spanning a century. Argentine ants are consistent throughout the valley and hillside portions of the city. Black widows are more prevalent in Los Gatos than in most South Bay cities given the hillside rock outcroppings and wood pile harborage.

Roof rats are the dominant pest complaint — Saratoga has more fruit and nut trees per household than virtually any other city in Santa Clara County, and roof rats exploit this food source extensively. Drywood termites are active throughout the older housing stock. Gophers are a significant concern in the large irrigated lots throughout the city. Argentine ants are consistent year-round.

Drywood termites in the 60–70 year old housing stock are the primary structural pest concern throughout the city. Argentine ants are pervasive, with supercolonies extending throughout the fully-developed residential grid. Roof rats exploit the mature tree canopy — Los Altos has one of the densest mature urban canopies in the South Bay, with trees on virtually every street. Subterranean termites are active in crawl spaces with limited vapor barriers.

Subterranean termites swarm actively in Gilroy in February–April — the inland climate amplifies the wet-winter trigger for swarm activity more than in northern Silicon Valley cities. Norway rats from garlic and vegetable fields migrate into residential areas during field operations and harvest. Gophers are endemic in the irrigated residential landscaping and agricultural-adjacent yards. Argentine ants are intense in summer heat. German cockroaches are present in commercial food service throughout the historic downtown and commercial corridors.

Gophers are the signature pest of Morgan Hill — irrigated horse pastures, vineyard drip systems, and large residential lots create the consistently moist, easily-worked soil that pocket gophers exploit throughout the year. Subterranean termites swarm actively in spring given the irrigated soil conditions. Norway rats from agricultural and ranch operations are a consistent concern. Argentine ants are intense in summer heat.

Drywood termites in historic and mid-century residential neighborhoods are the dominant concern. Pre-1930 Professorville homes have the highest risk of extensive un-treated infestations. Subterranean termites near creek corridors and the bayfront. High real estate transaction volume drives WDO inspection demand.

Pocket gophers are the dominant pest complaint in Los Altos Hills — large irrigated lots, horse pastures, and the open soil of orchard areas create ideal gopher habitat throughout the community. Roof rats from the oak woodland and orchard trees are endemic in properties with mature fruit trees. Wildlife intrusion — gray squirrels and raccoons entering attics — is more common here than in any flat valley city given the open space adjacency. Drywood termites are active in older custom homes.

Los Gatos Creek provides the same rodent corridor pressure as it does downstream in Campbell and upstream in Los Gatos. Large irrigated lots throughout Monte Sereno see consistent gopher activity. Mature fruit and ornamental trees throughout the community create roof rat habitat. Drywood termites are active in the 1960s–1990s custom housing stock.
