A neighborhood built in one decade
Census estimates describe a strikingly uniform housing stock. Of 3,927 homes in Vincent, 3,675 are detached houses; townhomes, duplexes and apartment buildings together account for only about 250 units, and there are no mobile homes. Some 2,813 homes — about 72% — date from the 1950s, the median year built is 1956, and the survey shows nothing built since 2010. Nearly 78% of households own their home.
The county's planning chapter for the area describes the same pattern from the street: single-family houses built almost all at once, with improvements made here and there over the years. For pest control, that sameness matters. Houses of one generation tend to share the same weak points at the same time — original under-sink plumbing openings, attic and foundation vents with old screens, garage doors that no longer seal at the bottom. We expect a problem found in one Vincent house to be a likely one next door, and we inspect with that in mind. When our inspection turns up signs of termites in older framing, we note them in your report; PesPro does not perform termite fumigation.

What the county's plan says about these streets
Los Angeles County's East San Gabriel Valley Area Plan, released as a public review draft in June 2023, does not list a community called Vincent. It does describe an area it names East Irwindale: about 1.5 square miles bordered by Covina, West Covina, Irwindale, Baldwin Park, Azusa and Glendora. Those borders fit the neighborhood the Census calls Vincent, so the plan very likely describes this same area, although the county does not use the name.
The draft paints a flat area of curving streets that end in cul-de-sacs, frontage roads such as Cypress Street, some blocks without sidewalks and street trees that are sparse or missing. It notes active mining east of Vincent Avenue, the I-210 and freight rail nearby, and two flood channels — San Dimas Wash and Big Dalton Wash — that connect to the San Gabriel River. Shops cluster on Arrow Highway near Clydebank Avenue and along Irwindale, Vincent, Lark Ellen and Azusa avenues.
None of that is a pest record, but it hints at where pressure is likely to come from: rail rights-of-way, quarry margins and channel edges are the kind of open ground where rats can shelter before moving into yards and garages.

In Vincent, the West Nile season can start in June
The San Gabriel Valley Mosquito & Vector Control District tracks West Nile virus by community, and it lists Vincent by name as an unincorporated neighborhood of Los Angeles County. In 2021 the district logged six positive mosquito samples here, the first on June 21 — tied with West Covina for the earliest date in the whole district that year, out of 190 positives. In 2023 Vincent's first positive came on June 20; only Covina, on June 8, was earlier in a season with 245 positives district-wide. No dead birds tested positive in Vincent that year.
This year the virus showed up later: Vincent's first positive sample was reported on August 26, 2026, and the district has counted two so far, out of 219 across its territory. Neighboring communities in the same 2026 list include Covina with 17, West Covina with 20, Azusa with 5 and Baldwin Park with 4. Vincent did not appear in the district's lists for 2020, 2022, 2024 or 2025; 2025 was a quiet year with only eight positives district-wide.
The takeaway for residents is timing. When Vincent shows up in the record, it has tended to do so at the very start of the season, so tipping out standing water in May and June matters as much as it does in August.

Aedes mosquitoes and dengue next door
The California Department of Public Health keeps a city-by-city table of invasive Aedes detections, and Vincent has its own row. It marks Aedes aegypti as present. Aedes albopictus is currently listed as not found, but the state's history shows it was last detected in Vincent in 2023. These are container breeders, so a forgotten plant saucer, bucket or toy in the yard can be enough water for them.
The vector control district has also reported locally acquired dengue in the San Gabriel Valley: 11 cases in 2024, eight of them in neighboring Baldwin Park, and five in 2025. None was attributed to Vincent. We mention it because the mosquitoes that can carry dengue are already established here, not because of any local case.

Fleas, rodents and the county's typhus record
Los Angeles County Public Health counted 220 flea-borne typhus cases in 2025, the most on record and up from 187 the year before, with nearly nine in ten patients hospitalized. The fleas involved live on rats, stray cats and opossums. The 2025 outbreaks the county described were outside the San Gabriel Valley, and the figures are county-wide, not Vincent statistics.
Still, the connection is practical. Keeping rats out of attics and garages, and treating pets for fleas year-round, cuts the chance that fleas settle in around a house. We handle rodent exclusion and flea treatment as separate services, and we can plan them together when an inspection shows both.

Who handles what in an unincorporated community
Because Vincent has no city government, some pest questions go to county or district agencies. Mosquito surveillance and control belong to the San Gabriel Valley Mosquito & Vector Control District, 1145 N. Azusa Canyon Rd. in West Covina, (626) 814-9466. For beehives, Los Angeles County Public Works says a hive on private property is the owner's responsibility through a private company, while one on county property goes to the Agricultural Commissioner at (626) 575-5471. Cockroaches, rodents, bed bugs and fleas inside and around your home are the work private pest control companies like PesPro do.
Language matters too. About half of Vincent residents age five and older speak Spanish at home, 36% speak only English, and smaller groups speak Chinese, Tagalog or Vietnamese. Our team works in English and Spanish, and our website is also available in Spanish at pespro.com/es and in Simplified Chinese at pespro.com/zh.
