What city tops the list for mosquitoes?
Orkin released its annual list of top mosquito cities, the metropolitan areas where they get the most calls for mosquito control.
Impacts heat and humidity can have on mosquitoes
Dr. Jennifer Breaux of the NOLA Mosquito Control Board joined FOX Weather Sky Dome to discuss West Nile Virus and mosquitoes.
As America heads outdoors, hungry for picnics and barbecues after a long winter, something else is hungry, too – mosquitos. The bloodsuckers thrive in the heat and after summer showers.
Orkin put together their list of the 50 top mosquito cities based on the number of mosquito control treatments. Los Angeles tops the list for the third year in a row. Chicago and New York held the No. 2 and 3 spots for another year.
Charlotte, Raleigh-Durham, Phoenix, Milwaukee and Memphis all jumped five to 15 spots on the list of worst mosquito cities. San Francisco, West Palm Beach, Cincinnati and St. Louis all fell between eight and 15 slots.
New to the list is Oklahoma City, which placed a strong 28 for a first-timer. Austin, Spokane, Bakersfield and Fresno also placed for the first time and rounded out the top 50.

Not just a pest
Swatting at the bloodsuckers and the relentless itching afterward are just minor irritants compared to what mosquitos carry. One mosquito bite can infect a person or pet with deadly diseases like malaria, dengue fever, West Nile Virus, encephalitis and Zika.
Worldwide almost 250 million people were infected by malaria, and 619,000 died, according to the World Health Organization.
In the U.S., West Nile Virus is a bigger concern. In 2021, 2,445 Americans were sickened by the virus, and 165 of them died, according to the CDC.
About one in five people infected with West Nile virus develop a fever along with other symptoms like headache, body aches, joint pain, vomiting, diarrhea and a rash, according to the CDC. Fatigue and weakness can last weeks to months, and no medicine attacks the virus.

The CDC states that about 1 in 150 people develop a severe illness of the central nervous system, like encephalitis or meningitis, spread by mosquitos. About 10% of those patients die.
Mosquito-borne illnesses are just as deadly to pets. Heartworm disease is the main mosquito-borne issue, according to Erik Olstad, Assistant Professor at the University of California, Davis’ Veterinary Medicine Teaching Hospital. The American Heartworm Society estimated that about 28% of dogs and 4% of cats suffer from heartworm annually.
"They will tend to accumulate in the chambers of the heart, and that pump no longer works effectively anymore," Olstad said. "And so this worm can not only cause heart failure but as the worms die, it can cause kind of an anaphylactic shock, reaction and thromboembolism and really horrible thing."

Mosquito prevention
The CDC advises homeowners to empty and scrub anything in the yard with standing water. Even puddles in holes in trees can breed mosquitos. For larger bodies of water not used for drinking, they recommend larvicides.
The EPA has a list of registered insect repellents for the skin that are safe and effective. Approved products carry an EPA symbol indicating how many hours the repellents work against ticks and mosquitos.
