Mosquito Control in Los Angeles — Yard Treatment and Larvicide Programs

Los Angeles has a growing mosquito problem driven by two invasive Aedes mosquito species: Aedes aegypti and Aedes albopictus (Asian tiger mosquito). Unlike native mosquitoes that breed in large water bodies, Aedes mosquitoes breed in small containers — flower pot saucers, bird baths, children's toys, clogged gutters, and even bottle caps. They bite aggressively during the day, unlike most native mosquitoes that are primarily active at dusk and dawn.

Both Aedes species can transmit viruses including dengue, Zika, and chikungunya, though local transmission in LA remains uncommon. The Greater Los Angeles Mosquito Authority (GLAMOMVD) monitors and treats public areas, but private property is the homeowner's responsibility.

Mosquito pressure in LA peaks during and after rainy periods (typically October–April) when standing water accumulates. The absence of rain from May–September does not eliminate mosquitoes — Aedes species breed in permanent water features. Summer remains an active mosquito season, particularly in areas with pools, water features, and irrigated gardens.

Step 1 — Inspection: We walk your property to identify all potential breeding sites and adult mosquito harborage areas (dense vegetation, shaded areas, standing water sources).

Step 2 — Breeding Site Elimination: We identify and treat or recommend removal of all standing water sources. Larvicide tablets (Bti — a naturally occurring bacteria) are applied to water features that cannot be drained (ornamental ponds, bird baths).

Step 3 — Adulticide Treatment: We apply a fine-mist insecticide to vegetation, fences, and resting areas where adult mosquitoes congregate during daylight hours. Treatment focuses on shaded, dense vegetation around the perimeter.

Step 4 — Ongoing Program: Monthly or bi-monthly treatments maintain suppression through the active season. A single treatment provides 3–6 weeks of protection under average conditions.

Yard mosquito treatment in Los Angeles costs $100–$300 per visit for a standard residential yard. Larger properties and those with extensive water features may cost more.

Seasonal programs (monthly or bi-monthly through the active season) provide better value than one-time treatments and maintain more consistent suppression.

Prices are estimates based on 2026 LA market averages. Actual cost depends on property size and treatment frequency.
