Most people associate mosquitoes with summertime. But in South Florida, mosquito season doesn’t follow a typical schedule—and if you’re waiting for “mosquito season” to arrive or end, you may already be too late.

Thanks to Florida’s subtropical climate, mosquitoes are active nearly year-round, with peak activity stretching from March through November—and sometimes even longer, depending on rainfall and temperature. At TORO Pest, we often get calls from homeowners surprised to be swarmed in February or December.

Understanding how and why mosquito season lingers in Florida is the key to protecting your home and family all year long.

Why Mosquitoes Thrive in Florida Nearly 12 Months a Year

Unlike northern states, where cold winters naturally suppress mosquito populations, South Florida offers mosquitoes everything they need to survive continuously:

• Warm temperatures rarely drop below the threshold mosquitoes need to remain active (around 50°F / 10°C).

• High humidity and frequent rain provide ideal breeding conditions.

• Lush vegetation offers plenty of shaded harborage areas.

• Standing water from irrigation, storms, and even condensation provides endless egg-laying opportunities.

When temperatures stay mild, mosquito eggs hatch faster, larvae develop more quickly, and breeding cycles continue without pause. That means even in the “off-season,” mosquitoes can be actively reproducing around your property.

The Dangers of Underestimating Mosquito Season

Many homeowners assume that treating mosquitoes once or twice during the summer will be enough. The reality is that seasonal treatments only offer temporary relief. Without year-round monitoring and suppression, mosquito populations can bounce back quickly—bringing not just discomfort, but health risks.

Mosquitoes in South Florida can transmit:

• West Nile virus

• Dengue fever

• Zika virus

• Chikungunya

• Eastern Equine Encephalitis (EEE)

• Heartworm disease in pets

Because the breeding season is so long, the risk window for these diseases is extended, especially in neighborhoods with poor drainage, standing water, or dense landscaping.

When Is Mosquito Activity Highest?

While mosquitoes can be active any time temperatures are warm enough, the peak season in South Florida typically follows this pattern:

• March to May – Rising temperatures jumpstart mosquito breeding.

• June to September – The combination of rain and heat creates explosive population growth.

• October to November – Activity slows slightly, but mosquitoes remain active during warm spells.

• December to February – Activity may dip, but doesn’t stop, especially in sheltered or irrigated areas.

Because many mosquito species lay dormant eggs that hatch after the first rains, populations can surge overnight, even after a short dry spell.

Why Waiting to Treat Mosquitoes Is a Mistake

Delaying mosquito control until you’re getting bitten is like waiting for a fire to start before buying a fire extinguisher. Once mosquitoes are active, they’re already breeding—and each female lays hundreds of eggs at a time.

Short-term fixes like sprays or candles may help with adult mosquitoes, but they do nothing to stop the next generation. A reactive approach almost always means more bites, more frustration, and greater health risk.
