Pest Control Across the San Fernando Valley

The Census Bureau treats the Valley as its own county division. Its 2020–2024 survey counts about 1.81 million residents and 682,800 homes there, across the Valley neighborhoods of Los Angeles plus Burbank, Glendale, San Fernando, Calabasas and Hidden Hills. Renters head 342,000 of the 645,000 occupied homes, or 53%.

Housing comes in two big families. About 320,000 homes are detached houses, while roughly 290,000 sit in buildings of five or more units, and 94,000 of those are in complexes of 50 units or more. The median home was built in 1968. The 1950s left the largest mark, with about 148,000 homes, and another 104,000 are older still.

Each family needs its own approach. In apartment blocks, German cockroaches and bed bugs travel through pipe chases, wall voids and corridors. One infested unit usually means checking the units beside, above and below it. In a seventy-year-old tract house, trouble tends to start at rusted foundation vents, loose attic screens, worn garage door seals and old plumbing holes. [1]

Farms covered much of the Valley before the postwar boom. A PBS SoCal history places citrus groves on the slopes of Encino, Pacoima, Canoga Park and Chatsworth. It also describes walnut orchards, plus poultry and dairy farms in Reseda, North Hollywood and Van Nuys. Farming began fading in 1940, and by 1967 about 40% of the land was residential.

Where a yard still has an orange, lemon or avocado tree, roof rats are likely to find it. UC IPM explains that roof rats eat citrus and avocados right on the branch, often leaving oranges hollowed out to the rind. They nest in dense shrubs and ivy and routinely travel 300 feet or more to feed, so a tree two lots away can support a nest in your attic.

So a Valley rodent inspection looks at the canopy as well as the attic. UC IPM advises removing limbs within 6 feet of the roof and thinning ivy on fences. We add trapping and metal mesh over roof vents, eaves and pipe openings, because rodents chew through foam. [2] [3]

On September 6, 2020, the official weather station at Pierce College in Woodland Hills reached 121°F. ABC7, citing the National Weather Service, called it the highest temperature ever recorded in Los Angeles County, two degrees above the previous record set in 2006.

Hot spells change what turns up indoors. UC IPM says the American cockroach thrives above about 82°F. It moves from sewers into ground floors through damaged pipes, missing screens or faulty drain traps. In Valley heat, these large reddish roaches tend to appear at night in garages, laundry rooms, tubs and floor drains.

For that species, a kitchen spray misses the source. We treat at the entry points instead: drain traps, sewer cleanouts, the gap where pipes meet the slab and the bottom seal of the garage door. [5] [6] [4]

The Greater Los Angeles County Vector Control District reports West Nile virus community by community, and Valley names fill much of its tables. In 2025, 137 of the district's 180 positive mosquito samples came from 25 Valley communities, with Valley Glen, Valley Village and Lake Balboa at 13 each. In 2023 the Valley's share was 165 of 300.

The 2026 table, updated October 21, lists positive samples from 30 Valley communities, starting with Sunland on May 22 and led by Studio City with 12. The Valley often opens the season, too: Winnetka produced the district's first positive of 2024 on May 2, and Burbank the first of 2023 on May 24.

The California Department of Public Health lists Aedes aegypti as present in Los Angeles, Burbank, San Fernando, Calabasas and Hidden Hills. This invasive mosquito bites during the day and breeds in small containers. The state also lists Aedes albopictus in Los Angeles and Glendale.

PesPro does not treat mosquitoes. Los Angeles, Burbank, Glendale and San Fernando belong to the Greater Los Angeles County Vector Control District. Calabasas and Hidden Hills belong to the Los Angeles County West Vector Control District. [7] [8] [9] [10] [13] [11] [12]

The Los Angeles River begins in the Valley. LA County Public Works places its Headwaters Area in Canoga Park, where Bell Creek and Arroyo Calabasas join to form the river. UC IPM lists streamside vegetation among the habitats roof rats favor. Homes backing onto a channel, wash or park are likely to see rats traveling along fences and utility lines.

Hillside streets on the Valley's rim bring a different mix. The Los Angeles Fire Department requires owners in the Very High Fire Hazard Severity Zone to maintain vegetation within 200 feet of structures. Overhanging trees must stay at least 5 feet above the roof. Clearance done for fire also removes the cover and roof access that rodents use.

Bees nest along those edges as well. In May 2023, a swarm on West Adlon Road in Encino stung an LAPD volunteer badly enough to need hospital care, and fire officials told neighbors to stay indoors. PesPro removes wasp, hornet and yellow jacket nests and relocates live honey bees when feasible. [14] [3] [15] [16]

Los Angeles County Public Health logged 220 flea-borne typhus cases in 2025, the most on record and up from 187 in 2024, and nearly nine in ten patients were hospitalized. The county says cases have been reported across its territory. These are county-wide figures, not Valley counts.

In 2012, LAist reported four cases among neighbors on one Burbank street and two more elsewhere in the Valley, spread by fleas from rats, cats and opossums. The county's advice reads like a pest-proofing checklist: year-round pet flea control, no pet food outdoors, trimmed brush and closed crawl spaces. We handle the rodent sealing and flea treatment parts. [17] [18]
