The U.S. Cities With the Most Mosquitoes, According to Orkin (2025)

by SharonKurheg

Mosquitoes are gross and potentially dangerous. And it’s not bad enough that a mosquito bite will give most people a welt and an itch to beat the band. Oh no – if you travel to the wrong places, you also get to worry about West Nile virus, eastern equine encephalitis, Dengue, Chikungunya, Zika virus , and malaria.

Good times.

The Top Mosquito Cities in the U.S.

As summer rolls on, some cities experience more mosquitoes than others. And since at least 2013, Orkin’s been releasing an annual list of the 50 cities in the U.S. that have the most mosquitoes. This year’s list is based on the number of new residential mosquito treatments performed by Orkin from April 1, 2024, through March 31, 2025.

“Mosquito control isn’t just about avoiding itchy bites,” said Frank Meek, Orkin entomologist. “It’s about safeguarding your health and your community. Proactive measures are key to controlling these seasonal surges in mosquito activity.”

Mosquito Prevention Tips: Remember BITE

From Orkin:

Mosquito control can seem extremely daunting, especially living in areas with such dense mosquito populations. However, there are a few simple preventive measures homeowners can take to help reduce mosquito activity. Consumers can use the acronym BITE to remember the steps.

  • Block access to skin by wearing long sleeves and pants, as well as CDC-recommended repellents.

  • Install tight-fitting screens on windows and doors.

  • Trim shrubs, grass and other vegetation to reduce mosquito resting areas.

  • Eliminate standing water, which is a breeding ground for mosquitoes.

LA is nowhere near the top in terms of mosquito problems than muggy eastern cities.

I suspect if anyone would know, it would be Orkin. And it’s been several years in a row, too. What can I tell ya? ¯\_(ツ)_/¯

Sorry, but I have to agree with Adam here. Been to LA many, many times and never encountered a mosquiito. It’s drier and there are fewer places for them to breed. This is true of most western cities, in general. Meanwhile, we have places like Minneapolis (the mosquito is the MN state bird), Orlando, New Orleans, Houston, New York City (very mosquitoey), Boston, etc, etc. I call BS on the list as well.

And, we’ve used Orkin. It’s surprising what they don’t actually know.

Maybe just more people in LA complain about the mosquitoes 😉
