Why We Monitor and Treat

STAY INFORMED, STAY SAFE

The Two Most Important Reasons:

  • Mosquito-borne diseases common to subtropical areas – West Nile virus, Dengue fever, Zika virus, Chikungunya virus, Eastern Equine Encephalitis, St. Louis Encephalitis, Malaria and dog heartworm
  • Large numbers of nuisance biting adult mosquitoes – a major problem to SW Florida’s economy and residential comfort

STAY INFORMED, STAY SAFE

Mosquito Biology

  • More than 50 species of mosquitoes in SW Florida
  • Of those, the District closely monitors 5 species that can make humans and pets sick with diseases they carry
  • The Southwest Florida environment promotes the growth of a mosquito from egg to adult in only 5-7 days

Collecting Data

  • The District monitors the community’s mosquitoes daily for population density, species identification, and presence of disease
  • Data collection is the cornerstone of the District’s Integrated Mosquito Management (IMM) program
  • A variety of traps (e.g., BG traps, CDC traps, etc.) collect mosquitoes for testing in our laboratory
  • The mosquitoes are counted, separated by species, and tested for the presence of disease
  • Landing rate count stations are located throughout the District — Field Technicians stand at the location for 2-5 minutes, counting the number of mosquitoes landing on them to collection additional data

How does the District Control Mosquitoes?

Learn more about the Control Materials used by the District.

Controlling Mosquito Larvae

  • Mosquito larvae are controlled by applying materials by truck, drone, or helicopter.
  • Larval control methods we use: Bti liquid (16 oz./acre), Bti granular (4-7 lbs./acre)

Controlling Adult Mosquitoes

  • Adult mosquitoes are controlled by applying materials by helicopter or airplane using Ultra Low Volume (ULV) technology. The ULV application releases material in droplets that are microscopic (i.e., about 20 microns). Little to no material makes it to the ground, and quickly dissipates – there is no residual effect.
  • The ULV application is made from 300′ altitudes where the material treats the air space where mosquitoes are active using one of these chemicals — all at rates less than one ounce per acre: Dibrom (0.46 oz./acre), Duet HD pyrethroid (0.8/acre ), and organic Merus 3.0 pyrethroid (0.83 oz./acre)

STAY INFORMED, STAY SAFE

The Decision to Treat for Mosquitoes is Based Upon:

  • Mosquito population numbers (larvae and adults)
  • Mosquito species identification (larvae and adults)
  • Compliance with material labels, rules and regulations
  • Weather conditions
  • Presence of disease in mosquito populations and health alerts (local, State and Federal)
  • Mosquito population data, including citizen complaints by website and phone
