Quick Answer
Florida has over 80 species of mosquitoes. The most important to know are: Aedes aegypti (Yellow Fever mosquito, primary vector for Zika, dengue, chikungunya), Aedes albopictus (Asian Tiger mosquito, aggressive daytime biter, carries Zika and dengue), Culex nigripalpus (primary vector for West Nile and St. Louis encephalitis), and Anopheles quadrimaculatus (malaria vector, historically significant). Florida has the highest mosquito-borne disease risk in the US.
Florida Mosquito Species Guide
Florida's warm, humid climate and abundant wetlands make it one of the most mosquito-prone states in the US. With over 80 mosquito species, only a handful are responsible for disease transmission. Knowing which species are in your area helps you take appropriate precautions.
Disease-Carrying Mosquitoes in Florida
| Species | Common Name | Diseases | Active Time | Breeding Sites |
|---|---|---|---|---|
| Aedes aegypti | Yellow Fever Mosquito | Zika, dengue, chikungunya, yellow fever | Daytime | Containers, tires, gutters |
| Aedes albopictus | Asian Tiger Mosquito | Zika, dengue, chikungunya | Daytime | Containers, planters, bromeliads |
| Culex nigripalpus | Southern House Mosquito | West Nile, St. Louis encephalitis | Dusk/night | Stagnant water, ditches |
| Culex quinquefasciatus | Common House Mosquito | West Nile, filariasis | Dusk/night | Polluted water, drains |
| Anopheles quadrimaculatus | Common Malaria Mosquito | Malaria | Dusk/night | Freshwater swamps, ponds |
| Psorophora columbiae | Rice Field Mosquito | Dog heartworm (pets) | Day/night | Flooded fields, ditches |

Aedes aegypti: The Most Dangerous Mosquito in Florida
Aedes aegypti is the primary vector for Zika virus, dengue fever, chikungunya, and yellow fever. It is a small, dark mosquito with white "lyre" markings on the back and white banded legs. It is an aggressive daytime biter that prefers to feed on humans. It breeds in small containers of water — flower pots, bird baths, gutters, tires, and even bottle caps. This species is the focus of most mosquito control efforts in Florida.
Asian Tiger Mosquito (Aedes albopictus)
The Asian Tiger Mosquito is an aggressive daytime biter that is easily identified by its single white stripe down the back and white banded legs. It is slightly smaller than Aedes aegypti. It breeds in containers and is common in suburban areas. It is a vector for Zika and dengue, though it is less efficient at transmitting these viruses than Aedes aegypti.
West Nile Virus Vectors
Culex mosquitoes are the primary vectors for West Nile virus in Florida. They are active at dusk and night and breed in stagnant water rich in organic matter. The risk of West Nile virus is highest in late summer and early fall. Symptoms include fever, headache, body aches, and in rare cases, neurological complications.
Mosquito Control at Home
- Eliminate standing water — empty flower pots, bird baths, gutters, and containers weekly
- Use EPA-approved repellents (DEET, picaridin, oil of lemon eucalyptus)
- Install or repair window and door screens
- Wear long sleeves and pants during peak mosquito hours
- Use mosquito dunks (Bti) in rain barrels and ponds
- Report mosquito problems to your local mosquito control district
