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
