As mosquito season intensifies across the United States, Georgia is once again landing near the top of a national list tracking the country’s worst mosquito problems. According to Orkin’s newly released 2026 Mosquito Cities List, Atlanta ranked among the top five cities in America for mosquito activity, despite moving down one spot from last year’s rankings.
The annual report, based on residential mosquito treatment data collected between April 1, 2025, and March 31, 2026, highlights how warm temperatures, humidity, and seasonal rainfall continue fueling mosquito populations across the Southeast.
For Georgia residents, mosquito season has become an unavoidable part of spring and summer life, particularly across metro Atlanta where dense tree cover, suburban growth, retention ponds, and heavy rainfall create ideal breeding conditions.
Experts say Atlanta’s persistent presence near the top of the rankings reflects the city’s climate and rapid development patterns. Mosquitoes thrive in standing water commonly found around neighborhoods, stormwater systems, backyard containers, clogged gutters, and wooded properties throughout North Georgia.
While mosquitoes are primarily viewed as a nuisance, health officials continue monitoring mosquito-borne illnesses including West Nile virus and Eastern equine encephalitis. Public health agencies routinely encourage residents to reduce standing water around homes and use insect repellent during peak mosquito activity hours at dawn and dusk.
For newcomers relocating to Georgia from northern and western states, mosquito season can come as a surprise. The Southeast’s long warm season allows mosquito populations to remain active for much of the year, especially during humid summer months.
Atlanta’s growing population and suburban expansion have also increased the importance of mosquito management for homeowners. Communities with lakes, wooded green space, golf courses, or nearby wetlands may experience heavier mosquito activity throughout the season.
Pest control experts recommend several preventative steps for Georgia homeowners, including:
• Emptying standing water containers regularly
• Cleaning gutters and drainage areas
• Maintaining swimming pools and landscaping
• Using EPA-approved mosquito repellents
• Scheduling seasonal mosquito treatments if needed
Despite the seasonal annoyance, Georgia’s warm climate, outdoor lifestyle, and booming metro growth continue attracting new residents from across the country. For many newcomers, learning how to manage mosquitoes becomes simply part of adapting to life in the Southeast.
