Florida's Major Termite Species
Three Types Dominate Our Region
South Florida serves as home to multiple termite species, each posing unique challenges for homeowners. The three major types you will encounter are drywood termites, Eastern subterranean termites, and Formosan subterranean termites. Each species has evolved different survival strategies, resulting in distinct behaviors, damage patterns, and vulnerabilities.
Correct identification matters because treatment methods differ by species. The tentless treatment that eliminates drywood colonies may not address subterranean infestations that require soil treatment. A professional inspection identifies which species are present and informs the treatment approach.
This guide details each major termite type found in Florida. Understanding their characteristics helps you recognize potential infestations and communicate effectively with pest control professionals about your situation.

Drywood Termites
The most common species in South Florida homes
Drywood termites are the termite species most frequently found inside Florida homes. They live entirely within wood without requiring soil contact, making them perfectly adapted to infest structures.
Identification
Drywood termite workers are creamy white and about 1/4 inch long. Soldiers have orange brown heads with large mandibles. Swarmers are dark brown to black with smoky wings and appear from late spring through fall. Colony size typically ranges from a few hundred to several thousand individuals.
Behavior and Habitat
Drywood termites establish colonies directly in wood without ground contact. They obtain all moisture from the wood they consume and from humidity in the air. Common infestation sites include attic framing, door and window frames, furniture, hardwood floors, and any exposed wood. A single structure can harbor multiple independent colonies.
Signs of Infestation
The telltale sign is frass, tiny six sided fecal pellets that accumulate in piles beneath infested wood. Termites push frass through small kick out holes to keep galleries clean. Other signs include hollow sounding wood, visible galleries when wood is broken open, and swarmers near windows or lights.
Treatment Approach
Drywood termites respond well to tentless treatment, our specialty at Florida Termite Guys. We inject treatment directly into infested wood, eliminating colonies without tenting or evacuation. For severe whole structure infestations, fumigation may be necessary.
Eastern Subterranean Termites
Ground dwelling termites causing widespread damage
Eastern subterranean termites are native to Florida and the most widely distributed termite species in North America. They require soil contact and cause more total property damage than any other termite type.
Identification
Workers are pale, soft bodied, and about 1/8 inch long. Soldiers have rectangular yellowish heads with dark mandibles. Swarmers are black with translucent wings and emerge in spring, often in large numbers following rain. Colonies can contain hundreds of thousands to over a million individuals.
Behavior and Habitat
Subterranean termites nest in soil and build mud tubes to reach wood above ground. They require constant moisture and die if exposed to dry air for extended periods. Colonies establish beneath or near structures and expand foraging networks over years. Workers can travel over 300 feet from the nest.
Signs of Infestation
Mud tubes on foundations, walls, or other surfaces are the primary indicator. These pencil width tunnels allow termites to travel between soil and wood. Wood damage has a layered honeycomb appearance with soil residue in galleries. Swarmer emergence in spring indicates a mature colony nearby.
Treatment Approach
Effective control requires treating the soil colony, not just the above ground activity. Liquid termiticide barriers around foundations eliminate termites as they attempt to reach wood. Bait systems offer an alternative that eliminates entire colonies over time. Treatment must address the ground based nest.
Formosan Subterranean Termites
The aggressive invasive species
Formosan termites are an invasive subterranean species originally from East Asia. Often called super termites, they form enormous colonies and cause damage faster than any other termite in the United States.
Identification
Workers resemble Eastern subterranean workers. Soldiers have oval heads with fontanelle pores that secrete a defensive liquid. Swarmers are yellowish brown, larger than native subterranean swarmers, and emerge at dusk during late spring. Colonies can exceed 10 million individuals.
Behavior and Habitat
Formosans share subterranean behavior but can also establish above ground nests called cartons in wall voids where moisture is available. This ability allows them to attack areas other subterraneans cannot reach. Their massive colony sizes enable rapid wood consumption and extensive damage.
Signs of Infestation
Similar to Eastern subterraneans but on a larger scale. Extensive mud tubes, sometimes thicker than those of native species. Large swarms at dusk during May and June. Carton material (brownish, spongy mass) in wall voids or tree cavities. Accelerated damage progression.
Treatment Approach
Formosan infestations require aggressive professional treatment. Soil treatment, bait systems, or both may be necessary. Above ground cartons require direct treatment. The enormous colony size makes complete elimination challenging. Multiple treatment sessions may be required.
Quick Species Comparison
Key differences at a glance
Moisture Needs
Drywood termites get moisture from wood and air. Subterranean and Formosan termites require soil moisture contact to survive.
Colony Size
Drywood: hundreds to thousands. Eastern subterranean: up to millions. Formosan: often exceeds millions. Size affects damage rate.
Entry Method
Drywood termites fly in and infest directly. Subterranean types tunnel from soil and build mud tubes to reach wood.
Damage Speed
Formosan termites cause fastest damage. Subterranean termites cause most total damage due to prevalence. Drywood damage is slower but cumulative.

Identifying Termites at Your Home
How to determine which species you have
Note the Evidence
Frass pellets indicate drywood termites. Mud tubes indicate subterranean species. Document what you see with photos if possible.
Check for Swarmers
Wing color, body size, and swarming time help identify species. Collect specimens if possible. Evening swarmers may be Formosans.
Consider Location
Damage in attics and upper floors often indicates drywood. Damage near foundations with mud suggests subterranean. Location provides clues.
