In Northeast Florida, termites are not a question of if but where. The heat, humidity and sandy soil around Jacksonville support several species at once, and wood-frame homes from historic Riverside to new subdivisions in Mandarin and the Southside offer plenty of meals. Swarms in spring are a familiar sight for residents.
Three termite types to know
Eastern subterranean termites are the most widespread. They live in the soil, send mud tubes up foundations and slab edges, and feed on structural lumber. Drywood termites live inside the wood they eat and are more common near the coast, including Jacksonville Beach, Neptune Beach and Atlantic Beach, where they infest attic framing, window trim and furniture. Formosan subterranean termites, an invasive species established in parts of Florida, form huge colonies and can eat wood extremely quickly; they have been found in the Jacksonville area, so accurate identification is important. Each species calls for a different treatment strategy.
Why Jacksonville homes are exposed
Many houses sit on slab foundations, where termites enter through expansion joints and plumbing penetrations. Historic bungalows and Victorians in Riverside, Avondale, Springfield and San Marco often have raised wood foundations with crawl spaces, where moisture and shade favor termites. Humid summers and heavy storms keep soil wet, and hurricanes can leave behind fallen trees and stumps that feed colonies near homes. Landscaping that touches siding, wooden decks and fences adds more pathways.
What to watch for
- Winged swarmers around lights or windows in spring and early summer.
- Mud tubes on foundation walls, crawl space piers or garage walls.
- Piles of tiny wood pellets beneath window frames, indicating drywood termites.
- Blistered paint, sagging floors or soft spots near baseboards.
- Doors and windows that begin to jam.
Inspection and treatment
A licensed inspector examines the crawl space, attic, slab edge, garage, wood trim and any outbuildings. Subterranean termites are typically controlled by a liquid soil treatment or bait stations. Drywood infestations may require whole-structure tent fumigation, or localized treatment with foam, heat or borate for small, accessible areas. Formosan termites call for a thorough plan that may include both soil and above-ground treatment, along with moisture correction. Florida requires licensed operators for termite work and provides rules for inspection documentation.
In coastal Jacksonville, salt air and humidity speed wood deterioration, so inspections are a good habit even without visible signs.
Prevention
- Keep mulch, soil and landscaping below the siding and slab line.
- Repair leaks, AC drain problems and roof damage quickly.
- Remove tree stumps, buried wood and construction debris.
- Keep gutters clean and downspouts well away from the foundation.
- Store firewood and lumber off the ground and away from walls.
- Screen attic vents and seal cracks in exterior trim.

Termite questions in Jacksonville
When do termites swarm in Northeast Florida?
Subterranean swarms often follow warm spring rains, while drywood swarms may occur in late spring and summer evenings. Formosan swarms tend to occur on warm, humid nights.
Can I tell which termite I have?
Often, yes: pellets suggest drywood, mud tubes suggest subterranean. An inspector confirms the species.
Do hurricanes affect termites?
Storms leave wet wood and fallen trees, which can feed colonies. Post-storm inspections are worthwhile.
Is fumigation always needed?
No. It is used for widespread drywood infestations. Smaller problems may be treated locally.
