Start with what you found
Drywood termites live inside wood. Subterranean termites usually forage from the soil. Formosan and Asian termites are two different subterranean species—not names for every termite in Florida. Conehead and dampwood termites have different habits again. Identifying the group is the first step toward understanding the evidence and choosing a treatment.
This guide brings together close-up insect images, pellet piles, mud tubes, nests and structural damage. Use the photographs to recognize a pattern, not to diagnose a whole property from one insect. A winged termite on a windowsill and a colony inside a wall are related possibilities, but they are not the same finding.
Why Florida has persistent termite pressure
Florida’s warm climate, moisture and abundant wood support several kinds of termites. UF/IFAS lists more than 20 species in the state, but only a subset are important structural pests. Some occur widely; others have more restricted distributions. A species recorded elsewhere in Florida is not proof that it is on your property.
Subterranean termites can exploit soil moisture, plumbing leaks and concealed routes through construction joints. Drywood termites do not need a connection to the soil: swarmers can enter exposed or accessible wood above ground. Coastal conditions, older woodwork, additions and recurring water intrusion all affect what an inspector needs to examine.
Concrete-block construction does not make a house termite-proof. Roof framing, furring strips, door frames, cabinets and other wood components can still be vulnerable. Tile or stucco may conceal activity rather than prevent it. The practical question is where termites can reach suitable wood and what evidence can be seen—not whether a home is described as “concrete.” Read more about where termites come from.
Drywood termites: colonies inside the wood
Drywood termites nest and feed within wood without needing soil contact. In Florida, the West Indian drywood termite (Cryptotermes brevis) is an important structural pest; other drywood species also occur. “Drywood” describes a group and its habits, not one universal insect appearance.
An infestation may involve trim, roof framing, fascia, door casings or furniture. Because separate colonies can occupy different pieces of wood, a small visible pellet pile does not tell you how many colonies are present elsewhere. The absence of mud tubes is consistent with drywood activity, but does not by itself establish the identification.
What drywood swarmers look like
Winged reproductives, called alates, have a broad waist, relatively straight bead-like antennae and two pairs of similarly sized wings. Body color varies with species and condition. Wings may extend well beyond the body and are often shed after a flight. The close-ups above show drywood alates. Consider the body, wings and surrounding evidence together.
Do not identify a termite solely as “the brown one” or assume a small wingless insect is a baby. A reproductive that has shed its wings can look very different from the same insect in flight. Our drywood identification guide covers the details.
Frass, kick-out holes and hidden galleries
Drywood termites push hard fecal pellets out through small openings called kick-out holes. Pellets can accumulate on a sill, floor, furniture or insulation below the infested wood. They are small, firm and characteristically ridged or faceted under magnification. Their color can vary, so black versus tan pellets is not a reliable species test.
Look above a pile as well as directly behind it: pellets fall, bounce and collect away from the opening. Sawdust and carpenter-ant debris tend to be irregular and fibrous; a clear close-up helps distinguish them from termite pellets. A pile left behind after treatment is not automatically proof of current activity, and old pellets can fall after vibration. Photograph the evidence and let an inspector assess it alongside the wood and any live insects. See what termite droppings look like.
What drywood evidence means for treatment
A localized treatment may be appropriate when activity can be identified and reached. Multiple affected areas, inaccessible galleries or widespread activity may lead to a whole-structure fumigation recommendation. The choice depends on the inspection—not simply whether you found one pile or several. Local treatment is not automatically whole-house coverage, and fumigation does not leave a residual barrier against future infestations. The drywood treatment guide explains the options.
Subterranean termites: soil, shelter tubes and concealed entry
Subterranean termites generally live in soil and reach food through concealed routes or shelter tubes. Florida has native Reticulitermes species as well as invasive Coptotermes species. They can share visible signs, but a mud tube does not identify a particular species.
Workers are usually pale, soft-bodied and wingless. Soldiers have more strongly colored heads and defensive structures. Winged reproductives look different again. Native subterranean soldiers generally have more rectangular heads than the rounded or teardrop-shaped heads of Coptotermes soldiers; reliable identification requires suitable specimens and magnification, not a distant phone photo of damage.
Recognizing mud tubes
Shelter tubes can run across foundations, garage walls, masonry, plumbing penetrations and other surfaces. They help termites travel while limiting exposure and moisture loss. Some are narrow trails; others are broad masses or branching networks. Activity may also be completely hidden behind finishes or inside construction gaps.
A tube’s presence is evidence worth investigating, but an old empty tube does not prove live activity today. Conversely, breaking a small section and seeing no insects does not prove the property is clear. Preserve evidence for inspection rather than repeatedly scraping it away. Our mud-tube guide shows what to look for and what to do next.
Why the damage can be hard to judge
A thin surface of paint or wood may remain over substantial feeding galleries. Some subterranean damage contains soil or carton material; exposed galleries alone do not establish whether termites are still active. Repairs and pest treatment answer different questions: a pest inspection identifies activity and treatment needs, while compromised structural members may also require evaluation by an appropriately qualified building professional.
Formosan termites: a subterranean species with large colonies
The Formosan subterranean termite, Coptotermes formosanus, is an invasive structural pest established in Florida. Mature colonies can contain millions of individuals and forage over substantial distances. That scale—not a special ability to eat concrete—helps explain why an established colony can cause extensive damage.
Swarmers, soldiers and carton nests
Formosan alates are typically amber-brown and have fine hairs on their wings. Soldiers have orange-brown, rounded to teardrop-shaped heads and curved mandibles; they can release a defensive secretion from an opening on the head. Workers are much paler. These are identification clues, not features that every homeowner photograph will resolve.
The photographs above show the winged Formosan stage, not workers. Compare the individual insect with the group: finding a swarm can leave many wings and bodies, while the feeding colony remains concealed elsewhere.
Formosan termites can build carton material from chewed wood, soil and other colony materials. Nests and feeding sites may occur inside trees or structures. Where a persistent above-ground moisture source supports them, an aerial infestation may not depend on an obvious soil connection. This is why inspecting only the foundation can miss an important part of the problem.
What a Formosan finding changes
The inspection should consider the structure, surrounding evidence, moisture sources and possible concealed or aerial activity. Soil treatment or baiting may address subterranean activity, but their scope must match the actual infestation. An aerial colony cannot simply be assumed covered by an in-ground system. Where fumigation is proposed for Formosan activity, it is a separate treatment decision—not the same ongoing protection as a drywood fumigation agreement or a baiting plan.
UF/IFAS describes Formosan dispersal flights in Florida as typically occurring from early April through late June, shortly after sunset, with a May peak. Weather and locality matter; a calendar alone cannot confirm the species.
Asian subterranean termites: similar evidence, different species
The Asian subterranean termite, Coptotermes gestroi, is another invasive species found in South Florida. It is distinct from the Formosan termite, even though both may produce mud tubes, carton material and substantial structural damage. Calling every subterranean termite “Formosan” hides that distinction.
Asian and Formosan termites can be difficult to separate. Specialists examine features of soldiers or winged reproductives under magnification. The color of a swarm, its location, or the appearance of a damaged board is not a dependable substitute. Swarming periods can overlap, so the time of year is supporting context rather than a final answer.
Why accurate identification still matters
The inspection and written treatment agreement should identify the pest and the work covered. Do not assume a plan includes every subterranean species, every location of activity or wood repairs. In particular, species coverage and aerial-infestation exclusions can differ between termite-baiting agreements.
The mud-tube and carton photographs in this guide illustrate evidence shared by subterranean termites; they are not presented as an Asian-versus-Formosan photo test. If a sample cannot be identified confidently, retaining it for specialist identification is more useful than assigning a name from the damage alone.
Conehead termites: distinctive nests and surface trails
Conehead termites, Nasutitermes corniger, are an invasive concern in South Florida. Soldiers have distinctive dark, pointed heads. Colonies can build conspicuous carton nests and covered trails over trees, vegetation, fences and structures. Their above-ground foraging behavior differs from the usual picture of termites moving only through buried soil routes or entirely inside dry wood.
Carton nests have a rough, built-up appearance. Assess a suspected nest alongside insects and trails. Do not label every dark lump on a tree a conehead colony.
Suspected conehead activity warrants prompt identification and reporting to the Florida Department of Agriculture and Consumer Services. Avoid moving infested wood, yard debris or nest material off the property while seeking guidance. Distribution and response programs can change; use FDACS termite guidance for current reporting information. Standard drywood or subterranean service coverage should not be assumed to include coneheads.
Dampwood termites: investigate the moisture as well as the insect
Dampwood termites are associated with wood containing substantial moisture. Florida’s dampwood termites include Neotermes species. Leaks, persistently wet wood and other moisture problems can create suitable conditions. They are different from drywood termites despite the similar names.
A dampwood finding should trigger a search for the source of moisture and an assessment of damaged material. Correcting water intrusion and addressing affected wood are important parts of management, but “fix the leak and the termites are definitely gone” is too simple. An inspection should determine the extent of activity and whether additional treatment is appropriate.
Insect size or color alone should not decide a treatment recommendation. The condition of the wood and the source of moisture help distinguish a dampwood problem from another termite infestation.
Which termite do I have? Compare the evidence
Start with the material you found and where it appeared. These patterns help narrow an inspection; they do not replace one.
| Group | Where activity is often found | Useful evidence | Important limit |
|---|---|---|---|
| Drywood | Inside trim, framing or furniture | Hard pellets, kick-out holes, swarmers | Pellets alone do not establish current activity or its extent |
| Native subterranean | Soil routes into structural wood | Mud tubes, live workers or soldiers, damaged wood | A tube cannot identify the species |
| Formosan | Soil-connected sites, trees and sometimes aerial sites | Subterranean evidence plus identifiable specimens; possible carton | No visible ground connection does not rule it out |
| Asian subterranean | South Florida soil-connected or concealed sites | Similar signs to Formosan; specimen identification matters | Timing and damage are not a reliable species test |
| Conehead | Trees, vegetation and structures | Surface trails, carton nests, distinctive soldiers | Seek identification and current reporting guidance |
| Dampwood | Wood affected by substantial moisture | Termites associated with wet or deteriorating wood | Find the moisture source as well as the infestation |
Termite swarmers or flying ants?
Winged termites generally have a broad waist, bead-like antennae and four wings of similar size. Winged ants have a pinched waist, elbowed antennae and larger front wings than hind wings. Wings may be folded, damaged or missing, so use more than one feature. A clear photograph from above and a retained specimen are helpful. See termites with wings and our flying-ant guide.
Warning signs: document the pattern, not just the insect
The most useful observations are pellet piles, mud tubes, shed wings, live insects and changes in wood. Sticking doors, bubbling paint or hollow-sounding trim can justify investigation, but they also have causes unrelated to termites. Avoid turning a nonspecific symptom into a diagnosis.
Record the room, approximate height, date and whether the evidence appeared again. Photograph the whole area, then a close-up with a scale reference. Do not open an electrical box, remove structural material or enter an unsafe crawl space to obtain a better picture. Small termite exit holes can help locate an emergence point, but do not reveal every affected member behind the surface.
For a fuller photo-by-photo checklist, use our guide to signs of termites. This page explains how those signs fit the different termite groups; that guide goes deeper into recognizing symptoms around the house.
Swarming and the termite life cycle
A colony begins when successful reproductives establish a suitable site. Eggs develop into immature termites, and colony members take on feeding, defense or reproductive roles. Workers or worker-like immature stages feed and maintain the colony; soldiers defend it; winged reproductives disperse to attempt new colonies.
Not every small pale termite is a newly hatched “baby,” and most homeowners will not see eggs in an intact infestation. Our guides to termite eggs and baby termites explain the distinctions.
What an indoor swarm does—and does not—tell you
Swarmers emerging from a wall, trim or another interior opening are a strong reason to inspect that area promptly. A few insects entering through an open door near an outdoor light are a different situation. Both deserve attention, but the latter does not establish that a colony is feeding inside the home.
Colonies generally take years to produce dispersal flights; the timing varies by species and conditions. You cannot date an infestation from a swarm alone. Removing visible swarmers does not eliminate a concealed feeding colony. Save a sample and follow the steps in what to do when you see a termite swarm.
When to watch in Florida
Different termite species disperse at different times of year and times of day. Native subterranean flights often occur in daytime; important drywood and Coptotermes flights often occur around dusk or at night. Weather can shift activity, and species overlap. Our Florida drywood swarming guide explains that group’s seasonal pattern. Evidence outside a typical season should not be dismissed.
Treatment follows the termite and the infestation
There is no single treatment that should be prescribed from the word “termites.” Species, access, the extent of activity, construction and moisture conditions all affect the recommendation. The summary below is a starting point; our termite treatment service page explains On Demand’s service options.
Localized drywood treatment and bonds
Localized treatments address identified areas that can be reached. A drywood bond may provide additional treatment during its stated term, subject to the areas, conditions and exclusions in the agreement. A spot-treatment agreement is not interchangeable with a renewable bond. Ask what wood or areas are included and what happens if evidence appears elsewhere.
Whole-structure fumigation
Fumigation can address drywood termites throughout the described structure, including inaccessible locations. Occupants must leave, follow preparation instructions and wait for clearance by the licensed fumigator before returning. Reentry is determined by the treatment and clearance process—not a promised universal number of days.
Fumigation does not leave residual protection against a new infestation. Drywood fumigation and Formosan fumigation also have different agreement terms; do not assume the same warranty applies. Read what termite tenting involves before comparing quotes.
Subterranean liquid treatments and baiting
Liquid treatments are applied to designated areas according to the product label and the treatment plan. Bait systems use termite feeding behavior and require the monitoring or maintenance specified by the agreement. Neither should be described as automatically covering every hidden aerial colony or repairing existing damage. Learn more about termite bait stations.
Other methods and DIY limitations
Heat is another method discussed in termite control, with access, temperature-distribution and residual-protection limitations. Our heat-treatment explainer is educational; its presence is not a promise that On Demand offers that method. Similarly, natural termite-control approaches and DIY treatments must be judged against the actual pest and the inaccessible parts of an infestation. Killing exposed insects does not show that a concealed colony has been controlled.
Inspections, cost and protection agreements
A termite inspection looks for visible evidence, access routes, conducive conditions and areas requiring further investigation. An inspector should explain what was accessible and what was concealed. A visual inspection cannot certify the condition of every surface inside a finished wall.
A standard service inspection and a wood-destroying-organism report for a property transaction are different services. Ask which you need before scheduling. Closing requirements depend on the transaction, lender and current program rules; a treatment recommendation is not the same document as a closing report. See inspection requirements, VA-loan termite inspections and what happens during a termite inspection.
Comparing quotes without comparing unlike work
Price depends on the species, building size, access and treatment scope. Compare the proposed method, covered areas, initial work, ongoing visits, renewal conditions and exclusions—not just the total. Our termite treatment cost guide is the place for the detailed pricing discussion.
Standard homeowners policies generally exclude termite damage; check your own policy rather than assume a particular loss is covered. A termite bond is also not automatically a damage-repair policy. Read what a termite bond means and the actual warranty terms for the service quoted. If framing is damaged, repairing termite damage is a separate consideration from stopping activity.
Prevention: reduce access, moisture and concealed conditions
Prevention lowers risk; it cannot make a Florida property immune to termites. Different termite groups exploit different conditions, so combine building maintenance with appropriate professional inspection and any contracted protection.
- Correct moisture problems. Repair plumbing and roof leaks, maintain drainage and avoid persistent wetting of structural wood. Investigate recurring dampness rather than covering its stains.
- Separate wood from soil where practical. Review siding, posts, steps, stored lumber and other bridges to the structure. Construction details matter; do not alter a structural support without appropriate advice.
- Keep inspection areas visible. Avoid burying the foundation edge behind soil, mulch or dense vegetation. A concealed area is harder to inspect even when the landscaping did not cause the infestation.
- Maintain vulnerable wood and openings. Repair damaged exterior wood and suitable seals or screens without blocking required ventilation or drainage. Do not seal over an active infestation as a substitute for treatment.
- Review additions and changes. Landscaping, renovations and new slabs may affect inspection access or a treatment area. Ask the provider before disturbing a protected zone or relocating stations.
- Arrange periodic inspections. Follow the agreement and recommendations for your property’s history and conditions. Do not wait for the next planned visit if new evidence appears.
Termites primarily threaten wood and property; they are not a blood-feeding household pest. For that common concern, see whether termites bite people. If you have found pellets, tubes or swarmers, request an inspection and keep the evidence available.

Frequently asked questions about Florida termites
Formosan termites are one subterranean species. Native subterranean termites and Asian subterranean termites are different species that can leave similar mud tubes and wood damage. A suitable insect sample helps establish the identification.
Hard, faceted pellets are consistent with drywood termites, but debris can be confused with sawdust and old pellets can remain after treatment. Photograph the pile and the wood above it. An inspection determines whether there is current activity and how far it extends.
Swarmers emerging from an interior opening warrant prompt inspection. A few entering through an open door from an outdoor swarm do not prove an interior colony. Save specimens and record where they appeared.
Yes. Roof framing, trim and other wood components may still be vulnerable. Termites can use concealed routes through construction gaps; concrete-block walls do not make the building termite-proof.
Sometimes. Localized treatment may be appropriate where activity is identified and accessible. Widespread or inaccessible activity may lead to a fumigation recommendation. The inspection and written scope determine the choice.
Fumigation does not leave residual protection against a new infestation. Any follow-up or warranty depends on the specific agreement. Drywood and Formosan fumigation terms are not interchangeable.
Photograph the insects, trails or nest and seek prompt identification. Avoid moving potentially infested material off the property. Contact FDACS for current reporting and response guidance.
No. A standard service inspection and a wood-destroying-organism report for a real-estate transaction are different services. Confirm the documentation your lender or transaction requires before scheduling.
Not automatically. Species, included areas, retreatment, renewal and damage-repair provisions depend on the written agreement. Read the specific terms rather than assume every termite bond provides the same coverage.
