Our Mosquito Control Process

01

Property Assessment

We identify standing water sources, dense vegetation, shaded resting areas, and other conditions that support mosquito populations.

02

Source Reduction Recommendations

We advise on eliminating or treating standing water — a critical complement to chemical barrier treatment.

03

Barrier Spray Treatment

A fine mist of EPA-registered insecticide is applied to foliage, ground cover, and shaded resting areas where mosquitoes hide.

04

Scheduled Follow-ups

Treatments are scheduled every 3–4 weeks throughout the season to maintain protection as the previous treatment breaks down.

5
Summer dry-season exterior painting window (brief and valuable)

Mosquito Control FAQ for San Francisco Homeowners

How often should San Francisco homeowners get mosquito control?
Given San Francisco's karl the fog: persistent summer fog from the pacific keeps temperatures at 55–65°f on the west side, most homeowners benefit from mosquito control at least once a year. Year-round fog moisture causing wood rot and paint peeling on west-facing Victorians often makes spring or fall the optimal time to schedule service.
What home types in San Francisco most need mosquito control?
Victorian Painted Ladies and Edwardian flats (most common exterior) and Spanish colonial and stucco in the Sunset and Richmond districts are the most common home types in San Francisco and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
How effective is mosquito barrier spray?
Professional barrier treatments reduce mosquito populations by 75–90% for 3–4 weeks. Effectiveness depends on rainfall (which degrades treatment) and how quickly populations recolonize from neighboring properties.
Is mosquito spray safe for children and pets?
When applied properly and allowed to dry (typically 30–60 minutes), EPA-registered barrier sprays are safe for people and pets. Organic (garlic and essential oil based) options are available for extra peace of mind.
What about mosquito misting systems?
Automatic misting systems spray at timed intervals (typically at dusk and dawn) using fine nozzles installed around the yard perimeter. They provide consistent, hands-free protection and are popular for large properties and entertainment areas.
Will treating my yard help if my neighbors have standing water?
Barrier spray kills mosquitoes that enter your yard, even from neighboring properties. Source reduction on your property significantly boosts effectiveness.
