Do you cover the whole of Los Angeles County?

Yes, from the Westside and the San Fernando Valley through the San Gabriel Valley, the Gateway Cities and the South Bay. The Cahuenga Blvd W office sits near the 101 between Hollywood and the Valley, so most of the county is a reasonable drive, and Orange County-side jobs run from the Huntington Beach office.

Why is LA County so bad for mosquitoes now?

Three invasive Aedes species are now established in the county. They bite in daylight and breed in containers holding as little as a teaspoon of water, with eggs that survive dry for up to two years. Los Angeles has also topped Orkin's mosquito city ranking multiple years in a row.

Doesn't the county handle rats and mosquitoes?

County vector control districts handle public spaces, standing water at public sites and disease surveillance. Two of the larger districts field about 140 staff for roughly 8.1 million residents, so private yards, attics and homes are left to the owner.

What is the most common pest call in LA County?

Argentine ants and roof rats lead most of the year, with termites close behind. Ant calls spike with heat waves and the first rains; rat calls climb as nights cool and roof rats move into attics.

Is murine typhus a real concern here?

Cases in California now occur mostly in eastern Los Angeles and Orange counties, carried by fleas on roof rats, opossums and skunks. It is a good reason to keep those animals out of attics and from under decks, and to treat fleas when wildlife is the source.

What we see here

A county with no off-season

Los Angeles County never gets the hard freeze that resets pest populations in most of the country, and that one fact shapes almost every job here. Argentine ants run supercolonies across whole neighborhoods and push indoors with every heat wave and every first rain. Roof rats travel the utility lines and mature canopy between houses, feeding on backyard citrus and avocados before settling into attics. Breeding cycles for roaches, fleas and mice simply never stop.

Wood is the second story. The county carries both termite families at once, drywood colonies living inside attic framing and eaves, and subterranean colonies working up from the soil, and coastal Southern California has the highest drywood prevalence in the continental US. That is why tented fumigation is a common sight from the basin through Long Beach and Pasadena, and why every general inspection here includes eyes on the wood.

Pressure by part of the county

How the problems shift across LA County

The basin and Westside

Dense older housing, shared walls and restaurant corridors: German roaches, bed bugs and roof rats lead.

The valleys

Hotter summers push Argentine ants indoors harder; pools, irrigation and brush edges add mosquitoes and wildlife.

Foothills and canyons

Raccoons, skunks, ticks, ground squirrels and bats come with the wildland edge above the neighborhoods.

Coast and South Bay

Marine-layer humidity favors silverfish, earwigs and drywood termites in older beach-area framing.

Local numbers

What the public agencies cover, and what they do not

Los Angeles County splits mosquito and vector work among several independent districts, and two of the largest field about 140 staff for roughly 8.1 million residents. Their focus is necessarily public: storm drains, parks, catch basins and disease surveillance. Mosquito season runs roughly June through November, Culex mosquitoes carry West Nile virus through the summer, and Los Angeles has been ranked the country's top mosquito city in Orkin's annual list multiple years running.

Private property is the owner's responsibility, and that is the work the crews do: the yard containers invasive Aedes breed in, the attic a roof rat colony uses, the perimeter Argentine ants cross. On the rodent side, California's AB 1788 restricts the strongest rodenticides, which is why rat control across the county is built on trapping and sealing rather than bait stations alone.
