Best Practice for Integrated Mosquito Management (components) Surveillance- habitats, larval & adult population, vector and
pest species Mapping/GIS/GPS-for resources and monitoring
Action. Florida Statues(Chapter 388 & 5E-13). Justification for pesticide application: Service request, LRC, traps, human and animal cases, sentinel chickens/mosquito pool, & weather condition
Source reduction (emptying containers, tire collection) Biocontrol (fish) Chemical control & Resistance monitoring Employee training & public education/community outreach
(enhanced) Applied research (enhanced collaboration) Quality control/ satisfaction survey/program review/evaluation Record keeping

Anastasia Mosquito Control District
AMCD is a special district (5 elected Commissioners) and a professional /technical service organization.
The District Staff, Technicians and all Inspectors/Sprayers have to be licensed and certified by DACS.

Bromeliads in downtown are one of major breeding sites
for Aedes aegypti & Ae. albopictus & a priority for
treatment
We treat larvae using BTI

MOU & AMCD’s Strategies
County DOH and AMCD had an MOU (Memorandum of Understanding) concerning human case release / street address
Targeted (Barrier) control: Systematic elimination/control of oviposition sites, ULV
spraying, and thermal/barrier spraying within a certain distance (< 300 m) of houses and spraying within 1 mile for Dengue, Zika, and Chikungunya, within 5 miles for WNV and EEE (save time and money), based on flight distance and activity patterns of vector species.
Non targeted control: Random elimination of the large numbers of oviposition sites
as the counterparts of targeted control and spraying whole area (time consuming with high cost).
Promotion of the Best Practices for IMM

Promotion of the DOH’s Drain & Cover-up
COVER doors and windows with screens to keep mosquitoes out
COVER skin with clothing and use mosquito repellent
DRAIN standing water to stop mosquitoes from multiplying
