As summer approaches, pest control company Terminix recently released the ranking of the “most severe mosquito cities in the United States in 2025”, with New York City topping the list ahead of traditionally hot and humid places like Dallas, Texas, and Atlanta, Georgia.
This ranking is based on the analysis of mosquito control service requests data from over 300 branches across the United States by the company. The report stated, “New York City claimed the top spot due to its unusually warm and rainy weather. While Los Angeles, Dallas, and Atlanta have long been top ranked, New York City saw a significant increase in humidity and rainfall this year, propelling it to first place.”
The report highlights that mosquitoes thrive in high temperatures, high humidity, and standing water, conditions that are almost all met in New York City during the summer. In recent years, New York’s summers have become increasingly hot and humid, leading many residents to comment, “Now summers in New York are becoming more and more like Florida.”
In addition to New York City, the only city from the tri-state area that made it into the top 50 is Hartford, Connecticut, ranking 47th. Texas, California, and Florida topped the list for states, with New York ranking eighth.
Mosquito season in New York typically runs from June to August, but climate experts point out that climate change is extending the high-temperature season in the Northeastern United States, also prolonging the period of mosquito activity.
West Nile virus is a common mosquito-borne disease in the United States, causing symptoms such as fever, headache, and, in severe cases, neurological diseases, posing a high risk for older individuals and those with weakened immune systems. The New York City Department of Health and Mental Hygiene (DOHMH) regularly conducts mosquito spraying, standing water control, and issues prevention measures to prevent West Nile virus infection.
To reduce mosquitoes, experts recommend promptly removing standing water from outdoor drains, flower pots, and other containers, regularly changing pet drinking water, and using screens and mosquito repellents. During the early morning and dusk when mosquitoes are most active, it is advised to avoid prolonged stays near grassy areas or ponds.
