Mosquito Disease Prevention in Orange County

Monitoring Status

Orange County is currently working to combat elevated mosquito populations. At this time, officials are asking for help from the community to minimize the potential for mosquito-borne illnesses among people, pets and livestock, as well as help reduce nuisance mosquitoes which can interfere with outdoor activities.

Mosquito Control Public Health and Safety

In addition to minimizing the presence of unwanted pests, Mosquito Control plays a key role in helping to ensure public and community safety. Orange County Mosquito Control has a working laboratory where researchers examine mosquitoes and larva found within the community. This information helps Orange County identify target areas for treatment and migration trends. Their efforts range from removing standing water, which serves as a breeding area, to providing research and information to partner agencies, along with spraying communities to rid them of mosquitoes. Mosquito Control works in partnership with the Florida Department of Health (DOH), which is the lead agency monitoring for the presence of infectious disease in Florida. DOH provides critical information to key partners throughout the state regarding the status or spread of infectious disease.

Gambusia Fish

Mosquito fish (Gambusia) are a species of fish that like to eat mosquito larvae. This tiny, noninvasive species is native to Central Florida and are commonly found in natural fresh bodies of water, including ponds, canals and lakes. Orange County Mosquito Control often release these fish as a way to naturally reduce mosquito populations. Gambusia fish are now available to Orange County residents, free of charge, and can be released into habitats where they are not already present.

For residents who are interested in Gambusia Fish, please call (407) 254-9120. Orange County Mosquito Control will survey the surrounding bodies of water to determine if Gambusia are already present in your area.

Mosquito-Borne Illness Prevention

  • Drain standing or still water to help eliminate breeding.
  • Apply insect repellants containing DEET (N,N-diethyl-m-toluamide) to repel mosquitoes.
  • Wear long sleeves, pants and socks to prevent bites.

  • Truck-mounted spraying with insecticides approved by the U.S. Environmental Protection Agency and state of Florida.
  • Surveillance using 27 special traps checked three times per week helps to identify the types of mosquitoes and estimate population size.
