In South Florida, a mosquito bite isn’t just an itchy nuisance — our subtropical climate makes Broward County one of the few places in the country where locally transmitted mosquito-borne diseases genuinely appear. Here’s what mosquitoes can carry here, and why controlling them around your Plantation home is a health issue, not just a comfort one.
Mosquito-Borne Disease in Florida at a Glance
- Main concerns: West Nile virus, dengue, Zika, chikungunya, and Eastern equine encephalitis (EEE)
- Key carriers: Aedes aegypti and Aedes albopictus (container breeders) and Culex species
- For pets: Mosquitoes spread heartworm to dogs and cats year-round
- Higher risk: Wet season (May–October), when populations and exposure peak
- Florida reality: Health departments issue local mosquito-borne illness advisories most years
Why Florida Is Different When It Comes to Mosquito Disease
Most of the U.S. only worries about mosquito-borne illness during a short summer window. South Florida is the exception. Our warm, humid, year-round climate supports the specific mosquito species that transmit serious viruses, and our role as a major travel and tourism hub means infected travelers regularly arrive and can seed local transmission. That combination is why Florida sees periodic locally acquired cases of diseases that are rare elsewhere in the country — and why Broward County health officials issue mosquito-borne illness alerts in many years.
The Diseases Florida Mosquitoes Can Carry
West Nile virus
Spread mainly by Culex mosquitoes, West Nile is the most consistently present mosquito-borne virus in Florida. Most infected people have no symptoms, but a minority develop fever, headache, and body aches, and a small fraction can develop serious neurological illness. Older adults are at higher risk for severe outcomes.
Dengue
Carried by Aedes aegypti, dengue causes high fever, severe headache, joint and muscle pain (its nickname is “breakbone fever”), and rash. South Florida has seen locally transmitted dengue cases in recent years, making it one of the more relevant concerns for Broward residents.
Zika
Also spread by Aedes mosquitoes, Zika is often mild but is most concerning for pregnant women because of the risk of serious birth defects. South Florida was at the center of the U.S. Zika response, which underscores how readily these viruses can establish here.
Chikungunya
Another Aedes-borne virus, chikungunya brings sudden fever and intense, sometimes long-lasting joint pain. Like dengue and Zika, it’s typically introduced by travelers but can spread locally given the right mosquito population.
Eastern equine encephalitis (EEE)
Rare but among the most dangerous, EEE can cause severe brain inflammation. It circulates in Florida’s wildlife and is occasionally detected in sentinel chickens that health departments use for surveillance — a signal of elevated risk in an area.
Don’t forget your pets: Mosquitoes transmit heartworm, a serious and potentially fatal parasitic disease, to dogs and cats. Because mosquitoes are active in Broward all year, the American Heartworm Society recommends year-round prevention for Florida pets. Reducing the mosquito population around your home protects the whole household — two-legged and four-legged alike.
How Florida Tracks the Threat
One reason Floridians don’t have to live in fear is the surveillance system working in the background. Mosquito control districts and the state health department monitor for disease year-round using sentinel chickens — flocks placed around the region whose blood is tested regularly for exposure to viruses like West Nile and EEE. When those tests light up, or when human cases appear, the county issues a mosquito-borne illness advisory and ramps up spraying in the affected zone. If you see an advisory for Broward County, treat it as a cue to be extra diligent about repellent, screens, and standing water around your Plantation home for the following weeks. It’s a signal that local transmission risk has genuinely risen, not just a routine notice.
Who’s Most at Risk
Anyone bitten can be exposed, but certain groups should be especially cautious in South Florida: older adults and people with weakened immune systems face higher risk of severe West Nile illness; pregnant women have specific Zika concerns; and outdoor workers and anyone who spends dawn and dusk hours outside during the wet season gets the most exposure. Around the home, the highest-risk yards are those with the most standing water — the very thing that breeds the disease-carrying Aedes mosquitoes.
How to Lower Your Disease Risk at Home
You can’t control whether an infected traveler arrives in Florida, but you can dramatically reduce the mosquitoes biting you and your family:
- Eliminate standing water — the container-breeding Aedes mosquitoes that carry dengue, Zika, and chikungunya thrive in tiny amounts of water in plant saucers, bromeliads, tires, and gutters
- Use EPA-registered repellent (DEET, picaridin, oil of lemon eucalyptus) during peak hours
- Repair window and door screens and keep them closed
- Cover up at dawn and dusk with long sleeves during the wet season
- Keep pets on year-round heartworm prevention
- Treat the resting areas where adult mosquitoes hide to cut the biting population
Because the riskiest mosquitoes breed in the smallest, easiest-to-miss water sources, a professional eye matters. Our mosquito control service in Plantation targets both the breeding sites and the adult mosquitoes resting in your landscaping, reducing the bites that carry real health risk.

Spot-spraying and citronella candles don’t meaningfully reduce a disease-carrying mosquito population. A professional program combines larvicide on standing water with a residual barrier treatment on the shaded areas where adults rest, sustained on a recurring schedule through Florida’s long wet season. In a region that sees periodic local transmission, keeping the population around your home low is genuinely protective. Explore how our professional mosquito extermination reduces both the nuisance and the risk.
Frequently Asked Questions
What diseases do mosquitoes carry in Florida?
The main concerns are West Nile virus, dengue, Zika, chikungunya, and the rare but serious Eastern equine encephalitis. Mosquitoes also transmit heartworm to dogs and cats. South Florida’s climate and travel volume make locally transmitted cases of these viruses more likely than in most of the country.
Are mosquito-borne diseases common in Broward County?
Severe illness is relatively uncommon, but Broward and neighboring counties do see periodic locally acquired cases and regular health-department advisories, particularly during the wet season. The risk is real enough that reducing the mosquito population around your home is a worthwhile precaution.
Can mosquitoes give my dog a disease?
Yes — mosquitoes transmit heartworm, a serious and potentially fatal disease in dogs and cats. Because mosquitoes are active all year in Florida, veterinarians recommend year-round heartworm prevention here. Reducing mosquitoes around your home adds another layer of protection for your pets.
How do I lower my family’s risk of mosquito-borne illness?
Eliminate standing water where disease-carrying Aedes mosquitoes breed, use EPA-registered repellent during peak hours, keep screens in good repair, and consider a professional treatment that targets both larvae and resting adults. Fewer bites means lower exposure to any virus mosquitoes might carry.
