Three Kentucky Cities Among Worst Cities for Mosquitoes in the US

Terminix just released its annual list of the cities with the most mosquitoes. As it turns out, three Kentucky cities are among the most infested in the country.

Mosquitoes are a big problem this time of year in Indiana. I think it's safe to say that we all have been swatting those pests. Mosquito season runs from April through September here in Indiana. Typically, mosquitoes become active at temperatures above 50 degrees Fahrenheit. However, they require temperatures above 70 degrees Fahrenheit to truly thrive. They also prefer moist, humid environments. These are prime breeding conditions, and warm areas with heavy rainfall may see increased mosquito populations and activity.  So, with all of the heat and rain we have seen so far this season, mosquitoes are coming out in full force.

No matter where you live in Kentucky, you can't hide from mosquitoes when you're outside. That being said, while you might find that there are a lot of mosquitoes in your neck of the woods, there's one Indiana city that I am grateful that I don't live in, because they have a much worse mosquito problem. It has one of the worst mosquito problems in the entire country.

Worst Cities for Mosquitoes in 2026

Terminix has identified the top 50 mosquito-infested cities across the United States. The list of these cities was compiled using service data from over 300 branches located throughout the country, based on where residents used the highest number of mosquito control services in 2025 in their designated market areas. As previously mentioned, three Kentucky cities made this list.

Coming in at number six on the top 50 list is Louisville. Then, you'll find Lexington at number twelve, and finally, Paducah came in at number forty-eight. Terminix also found that Kentucky as a whole is the fifth mosquito-infested state.
