Downtown Atlantaâs warm, humid climateâpaired with seasonal rainfall and dense urban infrastructureâcreates ideal conditions for mosquitoes across much of the year. From storm drains and catch basins to clogged gutters, shaded courtyards, and small containers that collect water, mosquitoes in the Atlanta metro area can stay active for long stretches, with the heaviest pressure typically building from late spring through early fall (and sometimes earlier when spring rains are heavy).
Georgia is home to 63 known mosquito species, but only a small number account for most of the biting, nuisance activity, and potential disease risk people worry about day-to-day in the Downtown Atlanta area.
Perhaps the most recognizable mosquito in the Atlanta area thanks to its black-and-white striped legs and aggressive biting behavior.
Active mostly during the daytime, especially early morning and late afternoon.
Breeds in small amounts of standing water â flowerpots, gutters, birdbaths, yard debris, and even bottle caps.
Known for being highly resilient and a major nuisance in residential and mixed-use areas.
Less common than Aedes albopictus in Georgia but still present in warmer, denser urban pockets.
Prefers to live close to human homes and bites primarily during the day.
Known globally as a vector for Zika, dengue, and yellow fever â though these diseases are not typically transmitted locally in Georgia.
These nighttime-biting mosquitoes are most active from dusk through early morning.
They prefer stagnant, organic-rich water such as storm drains, catch basins, ditches, birdbaths, clogged gutters, and ponds. Main carriers of West Nile virus in Georgia, which is detected in mosquito pools across the Atlanta metro area each summer.
Populations increase significantly during hot, humid weather following heavy rain.
Found near ponds, marshy edges, and still bodies of freshwater.
Active mostly at night and around dusk.
Historically associated with malaria transmission in the United States, though malaria is no longer endemic in Georgia.
