San Pedro is a harbor community of the City of Los Angeles, with the Port of Los Angeles on one side and ocean bluffs on the other. In ZIP code 90731, one home in four was built before 1940, and about two of every three households rent. That mix tends to bring rats along the waterfront and bluffs, cockroaches in damp ground floors and bed bugs in shared walls. PesPro serves San Pedro from its only office, in El Monte, about 28 miles away.

Neighborhoods and landmarks we cover: Downtown San Pedro and the Pacific Avenue corridor, the Vinegar Hill historic district, the waterfront along Harbor Boulevard and the World Cruise Center, Point Fermin and Paseo del Mar, White Point and the ocean bluffs, Barton Hill, South Shores and the 90732 hillsides, the Gaffey Street corridor.
Census estimates split San Pedro into two quite different areas. ZIP 90731, home to the waterfront, the cruise terminal and the older streets, has about 23,200 households, and roughly 67% rent. ZIP 90732 has about 9,400 households, and 72% of them own their home.
Building types follow the same split. In 90731, about 4,700 homes are in triplexes and fourplexes and 8,200 more in buildings of five or more units, so many tenants share walls and plumbing. In 90732, about half the homes are detached houses, and the median home dates to 1971, against 1965 in 90731.
Shared buildings mean cockroach and bed bug plans often have to include the neighboring units, with the owner's approval. Detached houses call for a closer look at rooflines, vents and the plantings around the yard. [1] [2] [5]
The Vinegar Hill historic district, adopted by the city in 2001, protects an early San Pedro suburb of modest single-family houses built from 1886 through 1927. Its streets mix Queen Anne, American Foursquare and Craftsman homes with later Colonial and Spanish Colonial Revival ones. Across 90731, Census estimates count about 6,100 homes built in 1939 or earlier.
Houses that age tend to collect small openings: foundation vents with tired screens, siding that has pulled away from its trim and pipe holes cut during decades of repairs. The city's rental inspectors check window and foundation vent screens on their routine visits. The same gaps are where rats, mice and cockroaches are likely to get in, and on historic homes we agree on mesh and sealing locations before any work starts. [3] [1] [9]
The Port of Los Angeles spans 7,500 acres of land and water, with 43 miles of waterfront, 25 cargo terminals and 15 marinas holding 3,736 recreational slips and dry docks. Its World Cruise Center sits in San Pedro at Harbor Boulevard and Swinford Street, and the port counted about 1.6 million cruise passengers in 2025.
For people who live nearby, the port matters in two practical ways. Waterfront storage, marinas and food businesses are likely to give rats steady food, water and cover. UC researchers note that the roof rat, also called the ship rat, favors warm coastal settings. A steady flow of travelers also means more luggage moving through hotels and homes, one of the ways bed bugs spread, according to county public health. [4] [5] [13] [11]
Along Paseo del Mar, the city runs Point Fermin Park and White Point Nature Preserve. The preserve covers 102 acres of former coastal defense and Nike missile land, which a 2001 city plan set out to restore as native habitat. Homes on the nearby streets sit close to that open ground.
UC IPM notes that roof rats nest above ground in shrubs, trees and dense plantings such as ivy. Thinning that growth makes a yard much less attractive to them. On bluff-side and hillside lots we look at ivy-covered walls and fences, limbs within six feet of the roof and the space under decks. Coyotes, raccoons and skunks are a matter for LA Animal Services, which advises residents on keeping wildlife out. [8] [7] [6] [13] [15]
The Greater Los Angeles County Vector Control District reports West Nile results by community, and San Pedro has its own line. The district logged two positive mosquito samples there in 2023, the first on August 31, and three in 2026, the first on August 18. Three dead birds from San Pedro also tested positive in 2026, while San Pedro was absent from the 2024 and 2025 tables.
Nearby, Wilmington logged nine positive samples and Harbor City two in 2026. The state lists both invasive Aedes mosquitoes as present in the City of Los Angeles. PesPro does not provide mosquito control; report standing water, green pools or heavy biting to the district at 562-944-9656 or GLAmosquito.org. [19] [18] [17] [16] [21] [20]
Los Angeles County Public Health logged a record 220 flea-borne typhus cases in 2025 and 109 more by late September 2026. These are county-wide numbers, and no public report places cases in San Pedro. The fleas live on rats, stray cats and opossums, which is why the county advises sealing crawl spaces, keeping pet food indoors and treating pets for fleas all year. [22] [23]
About 32% of San Pedro residents age five and up speak Spanish at home, rising to 38% in 90731. Roughly 10,000 of those Spanish speakers use English less than very well. Our technicians explain findings, quotes and prep steps in English or Spanish, and the website can also be read in Tagalog, Chinese, Korean and several other languages. [1] [2]

| Norway rats | Year-round | Burrows along foundations, under woodpiles and around waterfront trash areas |
| German cockroaches | Year-round | Kitchens and baths in triplexes, fourplexes and apartment buildings |
| Bed bugs | Year-round | Shared walls, luggage after trips and secondhand furniture |
| Mosquitoes (awareness only) | Late summer into fall | San Pedro's first positives came August 31 (2023) and August 18 (2026); report to the vector control district |

Read the originalNo. San Pedro is about 28 miles from our only office, in El Monte, and it is on our route. Recurring visits run on scheduled days, and same-day service is available for an extra fee when the schedule allows.
It should not. We agree on mesh and sealant locations with you first, use durable materials that can be painted to match and keep repairs small and out of sight where we can. If a repair would alter a visible feature, check with the HPOZ board before work starts.
The Greater Los Angeles County Vector Control District, which tests mosquitoes in San Pedro and the rest of the harbor area. Contact it at 562-944-9656 or GLAmosquito.org. PesPro does not offer mosquito control, though we point out standing water we notice during visits.
Yes. Restaurants, markets, offices and apartment buildings near Harbor Boulevard and downtown can book visits before opening or after close. In food areas we use products labeled for those spaces and keep service logs ready for the county's letter-grade inspections.
No. PesPro does not handle wild animals; in San Pedro, as elsewhere in the City of Los Angeles, LA Animal Services gives advice on wildlife. Once the animal has moved on, we can seal the rodent entry points around the house and treat for fleas if pets were exposed.
It tends to be. 90731 has more older and shared buildings, so cockroaches and bed bugs moving between units come up more often. 90732 has more detached houses, where roof rats traveling through vegetation and along rooflines are the usual concern.
It depends on the pest, the size and age of the building and how much sealing is needed. A technician inspects first, and you get a free written quote with the scope spelled out before any treatment.
