Subterranean Termites in Florida

Subterranean termites are Florida's most destructive pest. They build massive underground colonies and forage up through the soil to attack wood in your home's foundation, framing, and flooring. The Eastern Subterranean and Formosan Subterranean species are both present in Florida — the Formosan being far more aggressive.

They require moisture and maintain contact with the soil, which is why you'll see mud tubes — their highways between the ground and your wood. Without these tubes, they dehydrate and die.

Best Treatments:

  • Liquid termiticide barrier (Termidor) around foundation
  • Bait station systems (Sentricon) for ongoing monitoring
  • Soil treatment under slabs during construction

Subterranean Termite Facts

  • • Colony size: 100,000 to over 1 million workers
  • • Can consume 1 foot of 2×4 lumber in just 6 months
  • • Responsible for 95% of termite damage in the US
  • • Formosan colonies can exceed 8 million workers
  • • Swarm in spring, typically after rain
  • • Require annual inspections in Florida's high-pressure zones

Drywood Termites in Florida

Drywood Termite Facts

  • • Colony size: 1,000–10,000 workers
  • • No soil contact needed — live entirely in wood
  • • Produce distinctive hexagonal frass pellets
  • • Common in attics, furniture, and roof framing
  • • Swarm in summer and fall, attracted to lights
  • • Can spread to multiple wood members over years

Drywood termites are sneaky. They enter through small cracks in wood, attic vents, or gaps in rooflines and establish colonies entirely within the wood — no soil, no mud tubes. The first sign is often frass (tiny pellet droppings) appearing on windowsills or floors below infested wood.

Because they spread through wood-to-wood contact, a single home can have multiple separate infestations in different locations. When spread is extensive, whole-structure fumigation is the only complete solution.

Best Treatments:

  • Whole-structure tent fumigation for widespread infestations
  • Localized wood injection (Termidor Foam) for isolated colonies
  • Heat treatment for localized areas

Not Sure?

Which Termite Do I Have?

The fastest way to know for certain is a professional inspection. TAPS technicians are trained to identify both species and recommend the correct treatment — not the most expensive one.

You likely have Subterranean if:

  • You see mud tubes on your foundation or walls
  • Swarmers appeared near soil in spring
  • Damage is near the ground floor or crawlspace

You likely have Drywood if:

  • You find tiny pellet droppings near wood
  • Swarmers appeared near lights in summer/fall
  • Damage is in attic, furniture, or upper framing
