Pest Control in Santa Clarita: Valencia, Saugus, Newhall and Canyon Country

Santa Clarita became a city on December 15, 1987, after voters in Canyon Country, Saugus, Newhall and Valencia approved Measure U by 14,723 to 6,597. It began at 39 square miles. More than 30 annexations later it covers over 60, and in 2017 the city called itself the third-largest city in Los Angeles County.

Census estimates count about 78,100 homes. The median was built in 1987, the 1980s added the most, about 20,200, and some 22,600 went up in 2000 or later. Fewer than 3,400 predate 1960. About 61% are detached houses, 11% are townhomes or other attached homes, and 72% of households own their home.

Age still varies by ZIP code area, and those areas include some unincorporated land. In 91321, which covers most of Newhall, the median home dates to 1978 and 39% of households rent. In Valencia's 91354 the median is 2000, and in Saugus's 91350 it is 1989, with 79% of homes detached.

Newer does not mean sealed. Tile roofs can leave openings at the eaves, garage door seals wear out, and utility and irrigation lines pass through walls. Older Newhall and Canyon Country buildings add tired vents and plumbing holes, so every inspection covers the roofline, garage and foundation. [3] [1] [2]

The city's Open Space Preservation District, formed after a 2007 vote of property owners, points residents to more than 12,000 acres of publicly owned greenbelt around Santa Clarita. How close that land sits to houses became clear in October 2019. The Tick Fire burned 4,615 acres around Canyon Country, destroyed 29 structures and threatened about 10,000 homes.

Wild land brings native rodents. UC IPM explains that deer mice usually stay out of towns unless fields, brush or other natural habitat surround them, and streets backing onto the greenbelt fit that description. Native woodrats, also called pack rats, can turn up around homes too; their furry tails set them apart from roof rats.

Deer mice are the main carrier of Sin Nombre hantavirus, so cleanup needs care. UC IPM advises soaking droppings and nests with a disinfectant before removing them, never sweeping or vacuuming them dry, and sealing openings larger than 1/4 inch. Near open space we rely on snap traps and sealing rather than poison bait. [4] [7] [18] [19]

Summers here are hot and dry. On July 7, 2018, the National Weather Service measured 111°F in the Santa Clarita Valley, according to SCVNews.com, which listed 93°F as the typical high for that date.

That climate suits a cockroach many residents have never heard of. UC IPM reports that the invasive Turkestan cockroach is displacing the oriental cockroach in southern California and other warm, dry parts of the state. It lives outdoors in water meter boxes, cracks between concrete blocks, leaf litter and potted plants, and moves indoors when numbers build.

When a yard has block walls, valve boxes and planters, our cockroach inspection starts outside. Treating those outdoor hiding places, and closing gaps under doors and around pipes, keeps the problem from moving into the kitchen. [8] [20]

The Santa Clara River and its tributary washes cross the city. The city calls its regional river trail the backbone of about 80 miles of trails and 20 miles of paseos. It also warns that under-crossings along the river and its tributaries can flood and close without notice.

Streamside brush is rodent country. UC IPM lists vegetation on riverbanks and streams, along with mature landscaping, among the places roof rats nest, and notes that they travel 300 feet or more for food. Homes near the river, its washes or landscaped slopes are likely to see rats moving along fences and utility lines at night. [5] [19]

Mosquito surveillance and control belong to the Greater Los Angeles County Vector Control District, which lists Santa Clarita among its member cities. In September 2011 the district reported the year's first positive mosquitoes in Newhall and Canyon Country.

Its recent tables show small numbers here, mostly late in summer. Santa Clarita had one positive sample and one dead bird in 2021, five samples in 2023 starting September 15, and four in 2024 starting July 9. The city did not appear in the 2022 or 2025 tables.

Through October 21, 2026, the district had logged one positive dead bird in Valencia, found September 23, and one positive mosquito sample in nearby Castaic, which is outside the city. The state also lists Aedes aegypti, a daytime biter that breeds in small containers, as present in Santa Clarita. PesPro does not treat mosquitoes. [9] [11] [12] [13] [15] [14] [16] [10]

About 15,500 homes sit in buildings of five or more units, 8,300 are townhomes or other attached homes and roughly 2,700 are mobile homes. The ZIP code area 91351 in Canyon Country alone has about 1,850 mobile homes. The city oversees space rents in its manufactured home parks under Municipal Code chapter 6.02.

Each type has its own weak points. Shared walls in condos and apartments let German cockroaches and bed bugs move between units. Under manufactured homes, gaps in skirting and utility openings tend to let rodents and outdoor cockroaches in. We work with owners, tenants, HOAs and park managers on plans that cover every affected home. [1] [2] [6]
