Most of the United States has a pest season. South Florida does not. It has a pest year.
The combination of year-round warmth, humidity that rarely drops below 70 percent, sandy moist soil, and a rainy season that dumps 50 to 60 inches of rainfall annually creates conditions that support active pest populations every single month. There is no winter freeze to kill off mosquito larvae. No cold snap to drive termites dormant. No dry season long enough to collapse cockroach populations.
If you are moving from a northern or inland state, the adjustment is real. Pests that were a seasonal nuisance where you came from are a year-round management challenge here.
Florida ranked number one in the country for termite activity in the 2025 Terminix national report. Palm Beach County and the Treasure Coast sit in the heart of the highest-risk zone in the highest-risk state.
This is the big one. Florida's heat and humidity create year-round termite pressure unlike anything in the rest of the country. The state hosts multiple species simultaneously — native subterranean termites, drywood termites, and two highly destructive invasive species: the Formosan subterranean termite and the Asian subterranean termite. A 2026 UF/IFAS study confirmed that invasive termite species are spreading farther north across Florida than previously predicted, putting communities throughout Palm Beach County and the Treasure Coast in their path. The National Pest Management Association estimates termites cause $6.8 billion in property damage across the U.S. every year. Standard homeowner's insurance covers none of it. If you are buying a home in South Florida without a current termite inspection and a protection plan in place, you are taking a significant financial risk from day one.
Florida's rainy season runs from June through September, and during that period mosquito populations in South Florida reach levels that genuinely affect outdoor quality of life. Ornamental planters, low-lying areas, clogged gutters, and standing water in any container become breeding grounds within days of rainfall. Unlike northern states where mosquito season is a few months of mild annoyance, South Florida mosquitoes are active for the better part of ten months. Ongoing prevention rather than reactive treatment is the only approach that works here.
The American cockroach - known locally as the palmetto bug - is a fixture of South Florida life that catches most newcomers off guard. These are not the small German cockroaches you may have encountered in apartment buildings up north. American cockroaches in Florida grow up to two inches long, fly, and enter homes through drains, sewer lines, and gaps in the foundation. Their presence has nothing to do with how clean your home is. It is a function of Florida's humidity and the sheer density of the population in the environment around your home. Regular perimeter treatments are the standard approach for South Florida homeowners who want to keep them out.
Ghost ants are tiny, nearly translucent insects that most newcomers have never encountered before. They are one of the most persistent nuisance pests in South Florida and are particularly attracted to moisture, which makes them a constant presence in kitchens and bathrooms. What makes ghost ants especially frustrating is that consumer sprays make the problem worse. When a ghost ant colony is disturbed, it buds, splitting into multiple satellite colonies that spread deeper into your home. Professional treatment using baiting systems that work with colony biology is the only approach that produces lasting results.
Roof rats are agile climbers that gain entry through rooflines, soffits, and overhanging vegetation. They are particularly active in Florida's coastal communities, where mature tree canopy provides easy access to rooflines. New residents are often surprised to hear scratching in the attic within months of moving in - this is one of the most common first-year pest experiences in South Florida.
South Florida has a significant population of Africanized honeybees that are established throughout the region. They look identical to regular honeybees but respond to disturbance with large, aggressive swarms. If you find a hive on your property, do not spray it. Call a licensed pest control professional for an assessment.
If you are buying a home, a WDO inspection should be part of your closing process. If you are renting or have already moved in without one, schedule a professional inspection within your first month. The earlier you establish a baseline, the better protected you are.
Perimeter treatments that address cockroaches, ants, and other common pests are standard practice for South Florida homeowners. This is not something you do once — it is an ongoing maintenance relationship with a licensed professional.
Walk your property and eliminate any standing water. Check gutters, planters, downspout drainage, and low-lying areas. Consider a professional mosquito treatment program before rainy season begins.
Gaps around pipes, utility penetrations, soffits, and foundation cracks are all potential entry points for the pests described above. A professional inspection will identify the most critical areas to address.
A termite bond is an annual protection agreement that covers ongoing inspections and retreatment if activity is found. For new South Florida homeowners it is one of the most financially sound decisions you can make in your first year.

Professional pest control is strongly recommended in South Florida. The species here – including invasive termites, Africanized bees, and ghost ants – have behaviors that make consumer products ineffective or counterproductive. A licensed professional with local expertise makes a significant difference in outcomes.
