Termites, Palmetto Bugs and Roof Rats in Fort Myers

Fort Myers hears thunder on 89 days a year, more than any other place in the country, and collects about 57 inches of rain. Heat and water on that scale keep termites, roaches and mosquitoes working through every month.

Fort Myers is the Lee County seat, a city of 86,395 people at the 2020 census that grew up beside the Caloosahatchee River. It was incorporated in 1885, the year Thomas Edison bought 13 riverfront acres for a winter home, and the royal palms he had brought in for what is now McGregor Boulevard gave the city its motto, City of Palms. A real estate boom tied to the Edison Bridge added subdivisions beyond downtown, including Dean Park, Edison Park and Seminole Park.

Those older streets matter to us. A house from that era, shaded by tall palms and decades of planting, shelters different insects than a newer one out toward Gateway. Roughly two thirds of the annual rain falls from June through September, so our visits follow the calendar: termites and ants in spring, mosquitoes and roaches once the daily storms begin.

Pests in Fort Myers

Formosan subterranean termites

The University of Florida's termite map is dense with Formosan subterranean termite records around Fort Myers, among them a long run of collections across the river in North Fort Myers from 2018 through 2026. These colonies live in the soil, number in the millions and attack live trees as well as buildings. Winged swarmers gather at lights after sunset in April, May and June. The map also logs an Asian subterranean termite sample near downtown in 2019, so we identify the species first.

West Indian drywood termites

West Indian drywood termites skip the soil entirely. A colony spends its whole life inside the wood it eats, whether house framing, furniture or a boat, and UF reports the largest populations in older buildings across the southern half of Florida, with collections in and near downtown Fort Myers since 2017. The giveaway is a small heap of hard, six-sided pellets under a hole a millimeter or two wide. Control is spot treatment of the wood or fumigation.

Palmetto bugs

In Fort Myers the name palmetto bug usually points to the American cockroach, Periplaneta americana, the largest of the common house-invading roaches at about 1.5 inches. UF describes it moving indoors two ways: up from the sewer through the plumbing, or across from a tree or shrub that touches the building. The Florida woods cockroach, Eurycotis floridana, shares the nickname. It cannot fly, keeps to palm bases, stumps and woodpiles, and generally gets inside by accident on firewood or stored items.

Roof rats

Roof rats are climbers. UF/IFAS describes them settling in attics, soffits, hollow walls and sheds, raiding fruit trees, and chewing through wiring and plastic water lines once indoors. In a city where Henry Ford named his estate The Mangoes, backyard fruit is part of the appeal. UF/IFAS Extension's rodent advice: no limbs hanging over the roof, rat guards on trunks, ripe fruit picked promptly, and snap traps, never live capture and release.

Mosquitoes

Lee County's 56,000 acres of salt marsh keep salt marsh mosquitoes hatching all year, according to the Lee County Mosquito Control District. In town the bigger nuisance is the yellow fever mosquito, Aedes aegypti, which UF says is still common in urban South Florida. It breeds in flowerpots, tires and other containers and bites in daylight, indoors and out. The district asks residents to dump buckets, birdbaths, clogged gutters and bromeliads and to trim the grass and shrubs where adults rest.

The pest year in Fort Myers

January to March: dry, mild, first swarms
Monthly rain stays under 3.5 inches from October to May. Native eastern subterranean termites send out winged swarmers on warm, still afternoons between January and April, often the day after a shower. It is a good stretch for an attic and foundation inspection and for cutting tree limbs back from the roof.
April to June: evening termite flights
Formosan subterranean termites swarm after sunset, with the heaviest flights in May, and West Indian drywood termites fly mainly from April through June. Florida carpenter ants also release winged adults in these months. Insects piling up at a porch light or dropping wings on a windowsill should be collected and identified.
June to September: the thunderstorm months
These four months deliver about 67 percent of the year's rain. Standing water in saucers, toys and gutters breeds container mosquitoes within days, fire ants move uphill or indoors when the soil is saturated, and American cockroaches head indoors from the sewers. Dumping standing water every week is the most useful habit.

Old Fort Myers houses, tall palms and the river

In Dean Park, Edison Park and the blocks off McGregor Boulevard, the house itself is often the attraction. Decades-old framing, trim and built-in woodwork are what drywood termites look for, and mature trees that touch the roof give carpenter ants and roof rats a bridge. We check attic framing, window and door frames and the eaves, then point out which limbs should come back from the structure.

Closer to the Caloosahatchee and in newer neighborhoods, the ground matters more. UF's termite prevention list is practical: make sure water runs away from the building, aim sprinkler heads and air conditioner drain lines away from the walls, end wood-to-ground contact, and keep six inches of foundation visible above soil or mulch. Bigheaded ants, confirmed in Lee County, announce themselves with loose sandy piles along driveway and walkway edges.

Fort Myers pest questions

When do termites swarm in Fort Myers?

It depends on the species. The native eastern subterranean termite swarms in daylight, on warm afternoons between January and April. Formosan subterranean termites fly after sunset from early April to late June, peaking in May, and West Indian drywood termites mostly between April and June. Keep a sample of any swarmers found indoors and ask for an inspection.

How do I keep roof rats out of my Fort Myers attic?

Take away the routes and the food. Trim branches that overhang the roof, put guards on fruit and palm trunks, and close gaps around pipes, wires and vents with hardware cloth or steel mesh. Pick fruit as it ripens and keep pet food indoors overnight. Rats already inside are best handled with snap traps.

Does Lee County spray for mosquitoes in Fort Myers?

Yes, when counts justify it. The Lee County Mosquito Control District has no fixed spray schedule; it treats adult mosquitoes only when surveillance shows populations above state thresholds, and it puts prevention and larval control first. That leaves the containers in your own yard to you, and containers are exactly where the day-biting yellow fever mosquito breeds.
