Know your ankle biter

Both are invasive, both bite during the day, and both breed in a bottle cap's worth of water.

Yellow fever mosquito

Aedes aegypti

Black with white bands on its legs, and a silver lyre shape on its back. Found in all 111 communities on the state's list. If it's biting your ankles on the patio at 2 in the afternoon, it's probably this one.

Asian tiger mosquito

Aedes albopictus

Black with a single white stripe down the middle of its back, and the same banded legs. Found in 34 communities, mostly in the San Gabriel Valley and foothills.

West Nile is running high this year

As of October 1, 2026, LA County has 86 human West Nile cases this season, 629 positive mosquito samples, 148 positive dead birds and 61 positive sentinel chickens.

West Nile is carried by Culex, the brown mosquitoes that bite at dusk and at night. The daytime ankle biters don't carry it, but they can carry dengue, Zika and chikungunya. Source: westnile.ca.gov.

What actually helps

Dump the water

Free, ten minutes a week

Aedes lay eggs in plant saucers, buckets, toys and clogged gutters. A weekly walk around the yard removes most of them.

The weekly yard check

Call your district

Free, public agency

Every part of LA County has a public vector control agency that inspects properties and finds hidden breeding spots.

Find your district

Treat the yard

$400–$1,000 a season

A pest control company treats the shady spots where mosquitoes rest, every few weeks through summer.

What to ask before hiring

Get a quote from a licensed local company

If you've already emptied the obvious water and you're still getting bitten, a recurring treatment usually makes the yard usable again. We're signing up licensed companies for spring. Leave your email and ZIP and we'll tell you when quotes open where you live.

Typical pricing: $100–$300 for a one-time treatment, $400–$1,000 for a season, depending on yard size.
