What You Need to Know About Mosquito Season in Florida

While the year-round temperate weather is one of the many perks of living in Florida, any resident of the Sunshine State can tell you those perks come with a price—including a nearly year-round mosquito season. Thanks to plenty of warmth and moisture, two conditions where mosquito populations thrive, mosquito season in Florida doesn’t have a clear beginning or end point. However, Florida mosquito species are most active in the spring and summer months, when warm temperatures combined with frequent, heavy rains produce thriving mosquito populations.

What You Need To Know About Mosquito Season in Florida

In any geographic region, mosquito season depends on rainfall and temperature. In many parts of the country, the first warm days of spring signal the start of mosquito season, and winter’s first frost signals the end—except in more arid areas, where mosquito populations don’t pose a problem even in colder months.

But while January is typically Florida’s coldest month, that’s still a relative term. Mosquitoes in Orlando, for example, have enjoyed mild winters in recent years. In January 2017, Orlando’s low temperatures dipped below 50 degrees Fahrenheit on only a handful of days, and daily highs generally reached the 70s and 80s. Fifty degrees is about the threshold for mosquito season: Below that temperature, mosquito populations die off; above it, they can live, reproduce and thrive.

Since mosquito larvae are aquatic, water is another critical factor in supporting mosquito populations, and rainfall and marine areas abound in many regions of Florida. Thus, due to water and warmth, most parts of the state harbor native and invasive species of this pesky and ubiquitous insect.

What Are Some Common Florida Mosquito Species?

Florida is home to about 80 known species of mosquitoes—more than any other state. Thirty-three species are known to cause problems for people and pets, and 13 of them can carry potentially serious diseases such as encephalitis or the West Nile or Zika viruses.

Two of Florida’s most common mosquito species are Aedes albopictus and Psorophora ciliata. More commonly known as the Asian tiger mosquito (or simply tiger mosquito) due to its black-and-white-striped body and legs, Aedes albopictus is native to Southeast Asia but has spread to many countries worldwide, including the United States. This species can carry many viruses that can infect humans, such as yellow fever, dengue fever, and Zika.

Native to the eastern United States, including Florida, Psorophora ciliata is more commonly known as the gallinipper thanks to its aggressive behavior around both humans and animals. Larger than Asian tiger mosquitoes, gallinippers are known to have a painful bite. Though this species can carry pathogens such as encephalitis and West Nile virus, it hasn’t been proven to play a significant role in human infection of these diseases. It, therefore, isn’t considered to be as much of a threat as certain other mosquito species.

How Are Florida Mosquitoes Controlled?

Since mosquitoes can carry a variety of diseases and tourism is an integral part of the Sunshine State’s economy, mosquito abatement is a primary focus for most urban areas. Parks, including theme parks and other urban or heavily trafficked areas, tend to be regularly fogged or sprayed. At the same time, larvicide is used in standing water to control mosquito populations at the larval stage. Local governments often use products such as Bacillus thuringiensis israelensis (Bti), a naturally occurring larvicide that the World Health Organization has deemed not harmful to humans, pets, environmentally sensitive areas, or aquatic habitats.

On the other hand, long sleeves and pants and heavy-duty repellent are recommended when spending time in nature parks, including areas like the Everglades and the Upper Keys.

The Good News About Mosquitoes In Florida

Fortunately, Florida has good news to report regarding its mosquito populations. In December 2016, the Centers for Disease Control reported more than 45 consecutive days with zero new cases of Zika transmission. This means the state’s efforts to control its mosquito populations have been largely successful, which is excellent news for residents and tourists. Still, public health officials note that problems from the disease could arise again if containment efforts are not continued.
