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

Los Angeles Ranked #1 in U.S. for Mosquito Activity – What Does It Mean to You

I'm the owner of Los Angeles Termite & Pest Control and monitor pest activity that impacts our community closely—and this year we have a whopper. Los Angeles has ranked as the United States' No. 1 mosquito city in Terminix's annual ranking.

Although it's not surprising with our balmy climate and lengthy summers, this ranking serves as a sobering reminder: mosquitoes are not only an annoyance—mosquitoes are a threat to public health. What this report means to local residents, and how our company can assist in protecting your family and property.

Why Mosquito Activity is Increasing in Los Angeles 

• Mosquito populations are exploding throughout Southern California because of several interrelated reasons:
• Warm temperatures almost all year round
• Urban settings with stagnant water (such as clogged gutters, fountains, or even plant saucers)
• Densely populated residential areas where mosquitoes can readily fly between houses

In addition, invasive species such as the Aedes aegypti—also called the yellow fever mosquito—have invaded Los Angeles and bite during the day and transmit viruses such as dengue, Zika, and chikungunya.

What the Ranking Means

Terminix bases its list on how many mosquito-related service calls they get in each city. The fact that Los Angeles is number one indicates that more homes than ever are struggling with mosquito infestations that need to be treated professionally.

Though these insects might appear to be nothing more than a summertime nuisance, they are a serious health issue. Mosquitoes spread:

West Nile Virus (which has had cases in LA County)

• Zika Virus
• Dengue Fever
• Chikungunya

What We're Experiencing Locally

Here at Los Angeles Termite & Pest Control, we've already seen a dramatic spike in mosquito-related calls in 2024 and 2025. Homeowners are calling to report:

• Recurring outdoor swarms
• Mosquitoes within the home
• Daytime biting

Mosquitoes breeding in backyard features and potted plants

Many of our clients are surprised to discover that these infestations don't necessarily originate in nearby parks or lakes—they may begin in their own backyards.
