Mosquitos in Headlines: What NE Florida Homeowners Should Know
If you've seen headlines about dengue fever in Florida this summer, you're not imagining it — case numbers are up. With "wet season" taking place in Florida, our team wanted to lay out what's actually happening, what it means (and doesn't mean) for those of us in Jacksonville and St. Augustine, and what to do about it.
What's Actually Happening with Dengue in Florida Right Now
As of late August, Florida had logged around 70 dengue cases since July, most of them in Hillsborough County — health officials there called it an unusual increase, and it's been the center of the state's attention. The Florida Surgeon General issued a statewide reminder ahead of Labor Day to take basic precautions.
For us in Jacksonville and St. Augustine: this surge hasn't reached Northeast Florida. We're not writing this because there's an outbreak nearby. We're writing it because the same wet-season conditions behind the outbreak elsewhere in the state show up in every yard here, too. Mosquitoes breeding faster than people expect isn't a dengue problem — it's a year-round Jacksonville problem that dengue just put in the news.
Why Wet Season Changes the Math
Northeast Florida's wet season, roughly June through September, checks both boxes mosquitoes need: it fills low spots, clogged gutters, and forgotten flowerpot saucers with water, and the humidity keeps those eggs hatching fast. In warm, wet conditions like right now, a mosquito can go from egg to biting adult in about a week.
That's why a yard that seemed fine in April can be miserable by August. The mosquitoes didn't move in — the rain just gave the ones already here more places to breed.
The Two Mosquitoes Behind Most of the Concern
Not every mosquito buzzing around your patio is a dengue risk, and that's worth knowing so this doesn't feel scarier than it needs to be. The species associated with dengue — Aedes aegypti and Aedes albopictus — are both present in Florida, and they have a few habits that make them different from the bigger, lazier mosquitoes you might be used to swatting at dusk:
They bite during the day, especially early morning and late afternoon — not just at "golden hour."
They breed in tiny amounts of water — a bottle cap, a clogged gutter, a saucer under a potted plant is plenty.
They stay close to home — literally. They don't range far, so if you have them, they're probably breeding somewhere on your property, not flying in from the woods next door.
That means most of what helps is within your own fence line, not something you're waiting on the neighborhood to address.
The State's Advice Is Basically "Spray, Cover, Drain" — And It's Good Advice
The Florida Department of Health has been pushing a simple three-part message, and we'll be the first to say it holds up:
Spray — Use an EPA-registered repellent (DEET, picaridin, IR3535, or oil of lemon eucalyptus) when you're outside during peak biting times.
Cover — Long sleeves and pants when it's practical, especially early morning and evening.
Drain — Walk your property weekly and dump anything holding standing water: gutters, saucers, buckets, kids' toys, tarps, birdbaths (change the water instead of dumping those, obviously).
Drain is where most Jacksonville yards fall short. It only takes a bottle cap's worth of water for these mosquitoes to lay eggs — so "I don't have a pond or a pool" doesn't mean you don't have a breeding site somewhere on the property.
Where Professional Mosquito Control Fits In
Personal habits like spray-cover-drain genuinely help, and we'd tell you that even if we didn't do this for a living. But there's a real limit to what a homeowner can catch on a weekly walk-through, especially with a big yard, mature landscaping, or neighbors who aren't doing the same weekly check.
That's the gap our mosquito control service is built for. Rather than a one-time spray, we treat the vegetation and resting areas where adult mosquitoes actually hide during the day — the shady, humid spots along fence lines, under shrubs, and in dense groundcover that a can of store-bought spray never reaches — and we come back on a regular schedule through the season so new hatches don't get a foothold. It's the same "reduce the breeding and resting sites" logic the state is recommending, just applied more thoroughly and on a schedule you don't have to remember yourself.
If you're already a termite or WDO customer with us, ask your technician about adding seasonal mosquito treatments — a lot of folks bundle it in once they realize how much more they're actually outside in the evenings once the mosquito pressure drops.
The Bottom Line
Dengue in the headlines is worth paying attention to, not worrying over. Northeast Florida isn't where this summer's cases are, but the same wet-season conditions apply here as anywhere else in the state. The recommendations haven't changed: less standing water, some personal protection during peak hours, and a treatment plan for the parts of your yard you can't fully manage yourself.
FAQ
Has dengue fever been found in Jacksonville or St. Augustine? As of this posting, the dengue increase making news has been concentrated in Central and South Florida, particularly Hillsborough County. Northeast Florida has not been a focal point of this summer's cases, but the mosquito species involved are present statewide, so basic precautions are still worthwhile here.
Do all Florida mosquitoes carry dengue? No. Dengue is spread specifically by Aedes aegypti and Aedes albopictus mosquitoes, and only when those mosquitoes have themselves picked up the virus from biting an infected person. Most of the mosquitoes in a typical Jacksonville yard aren't a dengue risk, but they're still worth controlling for comfort and for other mosquito-borne diseases.
Can you get dengue in Florida without traveling internationally? Yes — Florida does see locally acquired cases most years, meaning someone was infected within the state rather than while traveling abroad. Case counts vary a lot year to year and by county.
How often should I have my yard treated for mosquitoes during wet season? Most Northeast Florida properties do well on a recurring treatment cycle (commonly every few weeks) through the wettest, hottest months, since mosquitoes can complete a full life cycle in about a week when conditions are right. We can recommend a specific schedule based on your property.
Does rain really make mosquito problems worse, or is that a myth? It's real. Rain fills the small containers and low spots where Aedes mosquitoes prefer to lay eggs, and warm, humid air speeds up how fast those eggs hatch and mature. A property can go from "not really an issue" to "noticeably worse" within a week or two of a wet stretch.
