Los Angeles Ranks No. 1 on Terminix's Top 50 Mosquito Cities

MEMPHIS, Tenn. - April showers bring May… mosquitoes. Historically, May marks the start of mosquito season, but as overall temperatures rise across the nation, these pesky pests are starting to emerge sooner, and for longer periods, than in previous years.

Ahead of the upcoming mosquito season, Terminix, a Rentokil Terminix company, has identified the top 50 mosquito infested cities in the U.S.

The list, generated using Terminix service data from 2023, focuses on key metropolitan areas. Although these cities were pinpointed based on Terminix service data, any area that experiences seasonal temperatures above 55℉ is at risk of mosquito activity, with coastal regions and areas prone to higher humidity being the most vulnerable. 

The list was compiled using service data from over 300 of Terminix's branches located throughout the country, based on where residents used the highest number of mosquito control services in 2023 in the company's designated market areas.
