Precision Ground Treatments in Neighborhoods & Communities

PCMCD uses truck-mounted systems to apply both adulticides and larvicides directly in neighborhoods across the county. These operations are carefully timed, scientifically guided, and built for efficiency, safety, and environmental responsibility.

Liquid Larvicide Applications (Using A1 Misting System)

To prevent mosquito problems before they start, PCMCD also uses truck-mounted misting systems to apply liquid larvicides in targeted areas.

What It Does:

• Targets immature mosquitoes (larvae) in residential neighborhoods, catch basins, roadside ditches, stormwater systems, and containers that hold standing water.
• Delivers a fine mist of biological larvicide (typically containing Bacillus thuringiensis israelensis or Bti) to breeding habitats that are often hard to reach.

Where It’s Used:

• Urban and suburban areas where Aedes aegypti and other container-breeding mosquito species thrive. Aedes aegypti is know to transmit dengue, Zika, chikungunya, and Yellow Fever viruses.
• Especially helpful in densely populated neighborhoods, industrial corridors, and areas with persistent water-holding infrastructure.

Why It Works:

• Larviciding prevents the next generation of mosquitoes from ever becoming adults.
• Applying treatments based on mosquito life stage and habitat ensures products are used effectively, responsibly, and only where needed.

Surveillance-Driven Decisions

Every truck-based treatment, whether larvicide or adulticide, is guided by:

• Daily trap collections and field data to monitor mosquito populations
• Breeding site inspections by field technicians
• Environmental factors such as rainfall, flooding, or container presence

We align treatment type and timing with the mosquito life cycle, ensuring that every application is:

• Appropriate for the life stage present
• Scientifically justified
• Environmentally conscious
