Miami may be the most termite-diverse city in the country. Warm temperatures year round, high humidity, frequent rain and a steady stream of imported cargo and landscape materials have made South Florida a home to several different species at once. Concrete block walls give a false sense of security: roof trusses, door frames, cabinets and furniture are all wood, and termites find them.
The termites of Miami-Dade
- Formosan subterranean termites form huge soil colonies and can eat through wood fast. They are established in the Miami area and swarm in the evening, drawn to lights, often from late spring into summer.
- Eastern subterranean termites also occur in South Florida and enter structures through soil contact and slab cracks.
- West Indian drywood termites live entirely inside dry wood, with no soil connection, and are common in the region. They push tiny, hard fecal pellets out of kick-out holes.
- Powderpost beetles are not termites but often show up in the same inspections of old furniture and trim.
Why Miami construction matters
Concrete block and stucco houses throughout Coral Gables, Kendall, Little Havana, Coconut Grove and Pinecrest are built on slabs, with wooden roof framing under tile or shingle. Subterranean termites can reach framing through cracks in the slab and block, plumbing penetrations and expansion joints. Drywood termites enter through attic vents, soffits and fascia, or arrive in infested furniture. High-rise condos in Brickell and downtown are not immune either, since wood trim, cabinetry and door casings can host drywood colonies, and balcony planters bring moisture.
Warning signs
- Winged swarmers or piles of translucent wings near windows and lights, commonly after rain.
- Tiny pellets that look like sand or coffee grounds collecting under wood furniture or window frames.
- Mud tubes on exterior walls or in the garage for subterranean species.
- Paint bubbling over wood, hollow sounds when tapping trim, or doors that begin to stick.
How treatment works
An inspector checks the attic, eaves, garage, windows, fences and landscape timbers, as well as the soil line around the house. For subterranean termites, providers commonly treat the soil around the foundation with a liquid product or install bait stations. For drywood termites, options include whole-structure fumigation with a tent or localized treatments, such as injected foams and borates, when infestations are small and accessible. Formosan problems usually call for a more thorough plan, since colonies can be large and may also nest in walls above ground. After hurricanes, inspectors often see new infestations in storm-damaged wood.
Prevention for Miami homes
Keep mulch and soil off stucco and below weep screeds. Fix leaks, since moisture draws termites, and keep roof flashing and soffits sealed. Inspect furniture and wood items before bringing them inside, and store firewood and lumber away from the house. Turn off or shield outdoor lights near the house during swarm season, which helps reduce the number of swarmers that find a way in. Annual inspections are common in the area.

Termite questions in Miami
How do I know which termite I have?
Mud tubes suggest subterranean species, while hard pellets point to drywood. A licensed inspector can identify the species and recommend the right treatment.
Does tenting always have to happen?
Not always. Small, accessible drywood infestations can sometimes be handled with spot treatments, while widespread ones usually need fumigation.
Can termites live in a concrete house?
Yes, because the roof, trim, cabinets and interior framing are wooden. Termites enter through cracks and openings.
When is swarm season in Miami?
Formosan swarms are common from spring into early summer, while drywood swarmers often appear in the afternoon, and timing varies by species.
