Orkin Highlights Mosquito Management as Summer Approaches
As the summer season commences, Orkin emphasizes the urgent need for effective mosquito management with the release of its 2025 Top 50 Mosquito Cities List. This annual report ranks cities based on the number of new residential mosquito treatments conducted between April 2024 and March 2025. Los Angeles retains its position as the most mosquito-infested city for the fourth consecutive year, followed closely by Chicago, New York, and Atlanta. Notably, Detroit makes its debut in the top five, climbing five places, while Cleveland and Denver also enter the top 10 for the first time. This trend indicates a disturbing rise in mosquito activity, particularly in northern cities, as warmer temperatures extend the breeding season for these pests.
The report underscores the significant health risks posed by mosquitoes, particularly their role in the transmission of diseases such as malaria, which claims over 600,000 lives annually according to the Centers for Disease Control and Prevention (CDC). The growing prevalence of mosquitoes in urban environments makes proactive management strategies critical. Orkin's data highlights the importance of addressing mosquito populations not only for individual comfort but also for the broader public health implications during peak mosquito season.
California remains a focal point for mosquito activity, with five cities, including Los Angeles and San Francisco, featuring prominently in the top 50. The presence of standing water and increased temperatures are identified as primary contributors to the rising mosquito populations, necessitating that residents adopt preventive measures to mitigate risks. As summer progresses, the need for awareness and action against mosquito-borne diseases becomes increasingly critical, emphasizing the role of companies like Orkin in protecting public health.
In addition to the major cities, the report reveals notable rankings shifts; cities such as Indianapolis and Richmond see significant improvements, while others like San Diego and Boston experience declines. This variation reflects changing weather patterns and urban development that affect mosquito breeding habitats. As communities brace for the warmer months, the importance of comprehensive mosquito control strategies becomes paramount in safeguarding residents against potential health hazards.
