February Mosquito Precursor Activity in Southwest Florida: What Westfall’s Is Watching

At Westfall’s Lawn & Pest Control, we know mosquito season in Southwest Florida doesn’t begin when customers start calling about bites—it starts much earlier. February is one of the most important months we monitor because it signals mosquito precursor activity, the early conditions that allow populations to explode later in spring.

Even when mosquitoes aren’t obvious yet, they’re already preparing.

Why February Is Critical in Southwest Florida

Southwest Florida winters are mild, and February often brings:

  • Daytime temperatures in the 70s

  • Overnight lows that stay well above mosquito dormancy thresholds

  • Light rain events, morning dew, and coastal tidal flooding

These conditions are enough to reactivate mosquito breeding cycles. Once temperatures consistently stay above 50–55°F, mosquitoes begin hatching, feeding, and reproducing—even if homeowners don’t notice them yet.

This is why February is a key month for proactive mosquito control in Fort Myers, Naples, Cape Coral, and surrounding areas.

What Mosquito “Precursor Activity” Means

Precursor activity refers to the early biological and environmental signs that mosquito populations are building. During February, our Westfall’s technicians commonly observe:

  • Dormant mosquito eggs beginning to hatch

  • Larvae developing in overlooked standing water

  • Small but increasing adult mosquito activity

  • Breeding sites forming that will drive spring populations

By the time mosquitoes become a nuisance, this process has already been underway for weeks.

Common February Breeding Sites We Find

Even during the dry season, February creates ideal mosquito breeding opportunities. During routine inspections, Westfall’s technicians frequently find standing water in:

  • Clogged gutters and downspouts

  • Pool covers holding rainwater

  • Bird baths and plant saucers

  • Low-lying areas in lawns and landscaped beds

  • Irrigation systems with leaks or overspray

In Southwest Florida, Aedes mosquitoes—known for aggressive biting and disease transmission—are especially common around residential properties and thrive in these small water sources.

Mosquito Species Active in February

Several mosquito species common to Southwest Florida begin increasing activity this time of year, including:

  • Aedes aegypti and Aedes albopictus (daytime biters, container breeders)

  • Culex species (active at dusk and dawn)

  • Saltmarsh mosquitoes in coastal and estuarine areas after tidal flooding

These early populations become the foundation for the heavy mosquito pressure homeowners experience in March, April, and beyond.

Why Westfall’s Recommends Early Prevention

Waiting until spring often means reacting instead of preventing. February is when mosquito control is most effective because:

  • Breeding sites are easier to locate and eliminate

  • Populations are smaller and more manageable

  • Preventative treatments reduce population growth before peak season

  • Long-term mosquito control plans can be established early

At Westfall’s Lawn & Pest Control, our approach focuses on preventing mosquito problems before they start, not just treating them once they’re out of control.

What Homeowners Can Do in February

Westfall’s recommends homeowners:

  • Eliminate standing water weekly

  • Flush bird baths and plant trays

  • Clear gutters and drainage areas

  • Inspect irrigation systems for leaks

  • Schedule preventative mosquito services early

February inspections often reveal breeding sites homeowners didn’t realize were present.

Westfall’s Takeaway

Mosquito season in Southwest Florida starts quietly—and February is the warning sign. Precursor activity tells us mosquitoes are already setting the stage for spring.

By addressing mosquito control now, homeowners can enjoy fewer bites, lower disease risk, and a more comfortable outdoor season ahead.

Westfall’s Lawn & Pest Control is committed to helping Southwest Florida residents stay protected year-round through proactive, professional mosquito management.
