Drywood Termite Quick Facts

Size

Usually about 1/4 to 1/2 inch, depending on caste and whether wings are included

Color

Creamy white workers; soldiers have darker heads; swarmers are typically yellowish-brown to dark brown

How to Identify

Small piles of uniform, six-sided pellets, shed wings, tiny kick-out holes, or hollowed wood

Active Season

Colonies may remain active year-round; swarming is most noticeable during warm, humid evenings, often from spring into summer

Indoor or Outdoor

Primarily indoors within dry, sound wood, but colonies also occur in trees, dead limbs, lumber, furniture, and other wooden items

Day or Night

Most colony activity remains hidden at all hours; winged swarmers commonly emerge around dusk or at night

Diet

Cellulose found in dry wood, including structural lumber, trim, furniture, cabinets, and other wooden materials

About Drywood Termites

Drywood termites are wood-destroying insects in the family Kalotermitidae. Unlike subterranean termites, they do not need contact with soil and can establish an entire colony inside a piece of dry wood. South Florida properties may be exposed when winged reproductives swarm from nearby trees or infested structures, or when infested furniture and lumber are brought indoors.

Because the colony stays concealed inside the wood, activity may go unnoticed until pellets, discarded wings, surface damage, or hollow-sounding wood appears. Proper identification matters because drywood termites require a different inspection and treatment strategy than subterranean or dampwood termites.

Where Are Drywood Termites Commonly Found?

Outdoor and Transported Sources

Drywood termite colonies can begin in sound, relatively dry wood without soil contact. Common sources around South Florida properties include:

  • Dead branches and standing deadwood
  • Tree limbs, trunks, and natural wood cavities
  • Stored lumber and firewood
  • Fences, gates, and exterior wood features
  • Wooden sheds, decks, and detached structures
  • Infested furniture, cabinets, and antiques
  • Wooden crates, trim, flooring, and decorative pieces
  • Nearby buildings or trees that release winged swarmers

A colony can be transported inside a single infested item, which is why used furniture, reclaimed lumber, and other wood products should be inspected before being moved into a building.

Indoor Infestation Sites

Inside homes and commercial properties, drywood termites stay within the wood they consume. Common locations include:

  • Attic framing and roof sheathing
  • Window and door frames
  • Fascia, soffits, and eaves
  • Wall studs, beams, and other framing
  • Wood siding and exterior trim
  • Hardwood flooring and subfloor components
  • Built-in cabinets, shelving, and furniture
  • Wood around porches, balconies, and upper stories

Infestations are often concentrated in upper portions of a structure because swarmers can enter through roofline joints, eaves, cracks, knots, and openings around windows or doors.

South Florida Conditions That Support Activity

South Florida’s warm climate and abundant trees allow drywood termite colonies and seasonal swarms to persist. Risk may increase when a property has:

  • Unscreened attic, soffit, or roof vents
  • Dead limbs or infested trees near the structure
  • Weathered or unsealed exterior wood
  • Gaps around fascia, eaves, windows, or doors
  • Cracks, knots, or joints in exposed lumber
  • Stored lumber or firewood near the building
  • Used furniture or reclaimed wood brought indoors
  • Wooden fences, sheds, or detached structures nearby
  • Past termite activity that has not been fully evaluated

Drywood Termite Behavior and Colony Development

Feeding Habits

Drywood termites feed from inside wooden materials. Depending on where the colony is located, they may consume:

  • Structural framing and roof components
  • Window frames, door frames, and trim
  • Hardwood floors and subfloor materials
  • Cabinets, shelving, and built-in woodwork
  • Furniture, lumber, fences, and decorative wood

Their galleries follow the grain and may cross between harder and softer portions of the wood. Because the feeding occurs internally, the surface can appear intact even when hidden galleries are present beneath it.

Colony Development

A new colony begins after winged males and females leave a mature colony during a swarm. After landing, they shed their wings, pair, and enter wood through a crack, joint, knot, or other small opening.

Drywood termite colonies grow slowly and remain much smaller than many subterranean termite colonies. Even so, multiple colonies can occupy the same structure, and long-term feeding may weaken localized wood components.

Pellets and Kick-Out Holes

Drywood termites conserve moisture by producing hard, dry fecal pellets. Workers push these pellets out through tiny openings in the wood. Evidence may include:

  • Small piles resembling sand, pepper, or sawdust
  • Pellets that are uniform in size and six-sided under magnification
  • Repeated piles returning after cleanup
  • Tiny kick-out holes in trim, framing, or furniture
  • Pellets collecting on floors, counters, windowsills, or furniture
  • Color variations based on the wood being consumed
  • Shed wings near windows, doors, lights, or attic areas
  • Wood that sounds hollow when lightly tapped

Pellets are an important clue, but a professional inspection is useful because debris from beetles, ants, or ordinary wood deterioration may look similar from a distance.

Swarming and Movement

Most of the colony remains hidden inside wood. Winged reproductives are the stage customers are most likely to see moving openly. Swarms often occur during warm, humid conditions, and the insects may gather around lights, windows, doors, or upper-story areas.

After a short flight, swarmers shed their wings and look for a protected opening in nearby wood. Finding discarded wings indoors does not prove the exact colony location, but it is a strong reason to schedule an inspection.

Damage and Property Concerns

Wood Damage

Drywood termites consume cellulose and create galleries within structural and decorative wood. Damage is often localized at first, but colonies can remain hidden for years, and multiple infestations may be present in one building.

Possible signs or affected materials include:

  • Hollow or blistered-looking wood
  • Damaged attic framing or roof components
  • Galleries inside trim, flooring, or furniture
  • Loose or weakened wood surfaces
  • Pellet piles below kick-out holes
  • Discarded wings following a swarm

The visible sign may be far from the center of the colony, and surface appearance alone cannot show how much wood is affected. Inspection findings help determine whether activity appears limited or more widely distributed.

Health and Sanitation

Drywood termites are not known for biting people, stinging, contaminating food, or transmitting disease. The primary concern is their ability to damage wood and remain concealed while the infestation develops.

Business and Property Considerations

In commercial buildings, rental properties, and managed communities, termite evidence may concern occupants, delay transactions, or reveal damage that requires repair. Accurate identification and clear documentation are especially valuable when several parties are involved.

Because drywood termite treatment can differ greatly depending on colony location and extent, property owners should avoid assuming that every pellet pile or swarm requires the same solution.

When Are Drywood Termites Active in South Florida?

Drywood termite colonies can feed within wood throughout the year in South Florida. Activity becomes most visible when mature colonies release winged reproductives.

Swarming and noticeable evidence may increase during:

  • Warm spring and early-summer weather
  • Humid evenings and periods following warm weather
  • Late-afternoon or nighttime conditions favorable for flight
  • Seasonal swarm events from nearby structures or trees
  • Periods when doors, windows, or lights attract flying insects
  • Moves or renovations that disturb infested furniture or lumber
  • Storm cleanup that relocates damaged or infested wood

Swarm timing varies by species and weather. In South Florida, winged drywood termites are often noticed during evening hours, sometimes around lights or windows. A sudden appearance of swarmers may come from the structure itself or from a nearby outdoor source.

Pellet production and internal feeding can continue even when no swarmers are visible. Cleaning up pellets without locating the kick-out hole or affected wood may make the problem seem gone temporarily while the colony remains active.

How DIY Drywood Termite Control Falls Short

Drywood termites live deep within wood, so visible pellets or swarmers may reveal only part of the problem. Professional inspection is especially practical when pellets return after cleanup, wings appear indoors, wood sounds hollow, several areas show evidence, or the extent of activity is uncertain.

  • Treating Only the Visible Evidence| Cleaning pellets or killing swarmers does not reach termites feeding inside the wood. The colony may continue producing evidence from the same or another kick-out hole.
  • Misidentifying the Termite Type| Drywood, subterranean, and dampwood termites differ in habitat and treatment. A method intended for soil-associated termites may not address a colony sealed inside dry wood.
  • Missing Hidden Galleries| Surface sprays may not penetrate the internal gallery system or reach every occupied section of wood. Finished walls, roof framing, trim, and furniture can make colonies difficult to locate.
  • Assuming There Is Only One Colony| A building can contain more than one drywood termite colony. Treating a single visible spot may leave other areas of activity undiscovered.
  • Moving Infested Wood| Discarding, storing, or relocating furniture and lumber without an inspection may spread an infestation to another part of the property.
  • Choosing a Method Before Inspection| Localized treatment may be appropriate for limited, accessible activity, while broader infestations can require a different approach. The extent and location should guide the plan.

Lower-Impact Options

When appropriate, Pest Busterzz may prioritize careful inspection, precise localized treatment, removal of infested wood, monitoring, and exclusion recommendations to reduce unnecessary applications. The available options depend on the infestation and the property.

The Pest Busterzz Drywood Termite Treatment Approach

Pest Busterzz develops a treatment plan after identifying the termite type, locating evidence, and evaluating how widely activity may be distributed.

01

Inspection

We inspect pellet piles, kick-out holes, discarded wings, damaged wood, attics, eaves, trim, furniture, and other likely infestation sites. Findings are used to distinguish drywood termites from other wood-destroying organisms.

02

Targeted Treatment

Treatment depends on the location and extent of activity. Options may include removal of infested wood, localized wood or void treatment, structural heat, or whole-structure fumigation when appropriate and available. The inspection determines which categories merit consideration.

03

Monitoring & Follow-Up

Follow-up may include checking previously active areas, watching for new pellet accumulation, evaluating treatment results, and inspecting newly discovered evidence. Timing depends on the treatment selected and the conditions found.

04

Prevention

Recommendations may include screening vents, sealing accessible gaps and joints, maintaining exterior coatings, inspecting used furniture or lumber, removing dead wood near buildings, and arranging periodic termite inspections.

Yes. Several drywood termite species occur in Florida, and South Florida’s climate supports colonies in trees, structures, furniture, and other dry wooden materials. Risk varies by property, but pellet piles, discarded wings, or indoor swarmers should be evaluated rather than ignored.

Drywood termites live within wood and commonly produce piles of hard, uniform pellets. They do not build the soil shelter tubes associated with subterranean termites. Because swarmers and damage can still look similar, professional identification is recommended before selecting treatment.

They can. Colonies excavate galleries as they consume cellulose inside framing, trim, floors, furniture, and other wood. Damage may develop slowly and remain localized, but several colonies or long-term activity can affect multiple areas of a structure.

Drywood termites push pellets from small kick-out holes as they maintain their galleries. If the colony remains active, a pile may return after it is swept away. The location of the pile can help guide inspection, although the occupied wood may extend beyond the visible opening.

Swarmers are winged reproductive termites, often yellowish-brown to dark brown, with two pairs of wings that are similar in size. They may gather near lights or windows and shed their wings after landing. Ant swarmers have elbowed antennae and unequal wing pairs.

Drywood termites are not considered a biting or stinging pest, and they are not known to transmit disease to people or pets. Their practical significance is wood damage and the possibility of hidden colonies inside a building or wooden item.

A surface spray may kill exposed swarmers but may not reach termites living inside galleries. Localized treatments must reach the occupied wood, and widespread activity may require another approach. Incorrect treatment can also make it harder to evaluate whether the colony remains active.

One flying termite can come from an outdoor source, especially during a regional swarm. Multiple swarmers indoors, piles of shed wings, recurring pellets, or damaged wood make an infestation more likely and justify a professional inspection.

Schedule an inspection when pellets return after cleaning, swarmers or wings appear indoors, wood sounds hollow, visible damage develops, or an infested item may have been brought inside. Early evaluation helps define whether activity is limited or spread across several areas.

Yes. Because a colony can live entirely inside dry wood, termites may be transported in furniture, cabinets, flooring, reclaimed lumber, crates, or other wooden items. Inspect secondhand and stored wood before bringing it into a home or business.
