DRYWOOD TERMITE GUIDE

Drywood Termites in Sacramento, CA

Drywood termites are found throughout Sacramento and nearby Northern California communities. They live entirely inside dry wood, including roof framing, eaves, trim, and other structural components, and may remain concealed until pellet piles, discarded wings, or damaged wood appear. Fuller Termite provides localized treatment and whole-structure fumigation based on the extent of activity found.

DRYWOOD TERMITE OVERVIEW

What Are Drywood Termites?

Drywood termites are wood-destroying insects that live inside sound, dry wood without contact with soil. Unlike subterranean termites, the entire colony remains within the infested wood, where it feeds and builds chambers across the grain.

A colony begins when a pair of winged termites enters through a crack or small opening and seals itself inside. Colonies grow slowly and usually contain fewer than 1,000 termites, although several separate colonies can occupy one structure. The termites remove waste by pushing hard fecal pellets through small kick-out holes, allowing the outer wood surface to remain intact while damage develops inside.

DRYWOOD TERMITES AT A GLANCE

How Drywood Termites Live

The Colony Stays Inside the Wood

The colony, food source, and galleries occupy the same piece of wood. There is no underground nest or soil route connecting the termites to the structure.

Several Colonies Can Occupy One Building

Drywood termite colonies are smaller than subterranean colonies, but separate colonies may develop in the roof, walls, trim, flooring, or other wood at the same time.

Swarmers Begin New Colonies

During summer and fall, winged adults leave mature colonies and enter cracks or exposed wood. After shedding their wings, a pair can establish another colony inside the structure.

COMMON LOCATIONS

Where Drywood Termites Are Found in Sacramento Homes

Drywood termites in Sacramento homes are most often found in roof framing, eaves, exterior trim, window and door frames, wall framing, decks, and finished wood inside the property. Winged termites can enter through cracks, open joints, and exposed wood ends, including areas where paint or sealant has deteriorated.

Roof eaves, fascia boards, rafter tails, roof sheathing, and attic framing
Window frames, door frames, exterior trim, wall studs, and concealed framing
Decks, railings, fences, gates, pergolas, and detached wood structures
Hardwood flooring, built-in cabinetry, furniture, and stored lumber

IDENTIFICATION

Signs of Drywood Termites in Your Home

Common signs of drywood termites include hard fecal pellets, tiny holes in wood, discarded wings, indoor swarmers, and wood that has become hollow or weakened. The evidence may appear below or beside the infested area, so the location where a sign is found is not always the exact location of the colony.

Drywood Termite Pellets or Frass

Drywood termite droppings are small, hard pellets with 6 ridged sides. They often collect in piles resembling coarse sand beneath trim, windowsills, attic framing, furniture, or other infested wood.

Small Kick-Out Holes

Drywood termites push pellets from their galleries through openings typically smaller than 2 mm. These holes can be difficult to see and may be sealed after the pellets are removed.

Discarded Wings

Winged termites shed their wings after leaving a mature colony. Small piles of similarly sized wings near windows, doors, or light sources may indicate that swarmers emerged inside the building.

Drywood Termite Swarmers

Western drywood termites commonly swarm during daylight in summer and fall. Swarmers seen indoors usually point to a colony within the structure or another infested wood item nearby.

Hollow or Weakened Wood

Wood with advanced damage may sound hollow when tapped, break under light pressure, or feel thin at the surface. Paint and finish materials can remain intact while the wood beneath has been consumed.

Exposed Galleries

Drywood termite chambers are sometimes discovered when siding, trim, flooring, or wall coverings are removed. The galleries often cross the wood grain and contain compacted pellets or smooth interior surfaces.

Important Note: New pellets appearing after an area has been cleaned can support a finding of current activity. A lack of new pellets does not rule out termites elsewhere inside the wood.

TREATMENT OPTIONS

How Are Drywood Termites Treated?

Drywood termites are treated with either localized methods applied to identified infested wood or whole-structure fumigation. The appropriate method depends on the number of affected areas, their accessibility, and the possibility of additional colonies inside concealed framing.

Localized Drywood Termite Treatment

Localized treatment is used when drywood termite activity is limited to one area or a small group of accessible wood members. Small openings may be drilled into the galleries so treatment material can be applied directly to the affected wood. Infested wood may also be removed when the full affected area can be reached.

This method treats only the locations that have been identified. It does not reach colonies concealed in other parts of the structure, so accurate detection and access to the infested wood are essential.

Whole-Structure Fumigation

Whole-structure fumigation is used when drywood termite activity appears in several areas, extends into inaccessible framing, or cannot be fully reached with localized treatment. The building is enclosed under tarps, allowing the fumigant to penetrate visible and concealed wood throughout the structure.

Occupants, pets, and plants must leave during fumigation and aeration. The property is tested and cleared by a licensed fumigation professional before anyone returns.

Localized treatment addresses confirmed, reachable colonies. Fumigation treats accessible and hidden drywood termite colonies throughout the enclosed structure.

PREVENTION

How to Help Prevent Drywood Termites

Drywood termite prevention focuses on blocking winged termites from entering exposed wood and starting new colonies. These measures can reduce the risk of new infestations, but they will not eliminate termites already living inside the structure.

Keep exterior wood painted or sealed, paying close attention to eaves, fascia, trim, rafter tails, and exposed wood ends.
Seal cracks, open joints, and gaps around rooflines, windows, doors, utility openings, and adjoining wood components.
Install and maintain fine-mesh screens over attic vents and other openings that could admit termite swarmers.
Repair split, weathered, or deteriorated exterior wood before openings develop into suitable entry points.
Examine used furniture, stored lumber, and reclaimed wood for pellets, holes, or insect activity before bringing them indoors.
Remove dead branches, discarded boards, and unused lumber stored against or close to the building.

Preventive maintenance cannot confirm that a property is termite-free. Pellets, discarded wings, swarmers, or unexplained wood damage should be professionally inspected.

Drywood Termite Questions, Answered

Frequently Asked Questions

Are drywood termite pellets a sign of active termites?

Not always. Drywood termite pellets confirm that termites have occupied the wood, but pellets alone cannot show whether the colony is still active. Clean the area and check it again after several days. New pellets may indicate current activity, although movement or vibration can also dislodge older pellets.

How quickly do drywood termites damage a home?

Drywood termite colonies develop slowly, and substantial damage usually accumulates over several years. A building can contain multiple colonies, however, so the total damage may be more extensive than the size of one colony suggests. The appearance of the wood cannot reliably show how long the termites have been present.

Can drywood termites spread from furniture to a house?

Yes. Furniture, reclaimed wood, and stored lumber can carry an established drywood termite colony into a property. Winged termites may later emerge from the infested item and enter exposed wood elsewhere in the building.

Do drywood termites leave the wood?

Most members of a drywood termite colony remain inside the wood. Winged reproductive termites leave mature colonies during swarming season, usually in summer or fall, and can begin new colonies after entering another suitable piece of wood.

Can drywood termites be treated without tenting?

Yes. Localized treatment may be appropriate when every affected area has been identified and the infested wood can be reached directly. It is less reliable when colonies may be concealed behind walls, inside roof framing, or in several separate parts of the structure.

When is fumigation necessary for drywood termites?

Whole-structure fumigation may be recommended when drywood termite activity is found in multiple areas, extends into inaccessible framing, or cannot be fully located for targeted treatment. Fumigation reaches accessible and concealed colonies throughout the enclosed building.

What should I do after finding drywood termite pellets?

Clean up the pellets, note exactly where they appeared, and check the area again for new material. Arrange a professional termite inspection because the visible pellets cannot identify the colony’s location, current activity, or full extent.
