Drywood Termite Control in Pleasanton

Signs of Drywood Termites in Your Pleasanton Property

Drywood termites spend nearly their entire life cycle inside the wood they consume. By the time visible damage appears, a colony may have been active for years. Knowing the early indicators is the best way to limit structural damage.

Watch for these signs:

• Frass (termite droppings): Small, hard, pellet-like droppings found on windowsills, near gaps in wood, or below small kick-out holes are a reliable indicator of drywood termite activity.
• Shed wings: Swarmers shed their wings near windows and doors after finding a new nesting site. A cluster of small, uniform wings indoors points to an active or recently established colony.
• Small holes in wood surfaces: These “kick-out holes” are how termites expel frass from their galleries.
• Hollow-sounding wood: Tapping on an infested beam or floorboard produces a hollow sound as internal galleries expand.
• Surface blisters on wood: Galleries built close to the surface can cause paint or wood to blister and bubble.

One important distinction: drywood termites don’t build mud tubes. If you haven’t found mud tubes, that doesn’t mean your property is clear. Drywood termites in the Bay Area typically swarm in summer and fall, so swarming activity around your structure is another signal worth acting on promptly.

How Drywood Termites Differ from Other Termite Species

Treating drywood termites effectively starts with understanding why they behave differently from subterranean and dampwood termites. The approach that works for one species won’t necessarily work for another.

Subterranean termites enter structures from the soil and leave visible mud tubes. Drywood termites enter through exposed unfinished wood, roof vents, gaps in exterior trim, or infested furniture brought indoors. They nest and feed above ground in dry, sound wood, including structural lumber, attic beams, hardwood floors, window frames, and wooden furniture. They extract sufficient moisture from the wood itself, so Pleasanton’s dry climate doesn’t deter them.

Drywood termite colonies are typically smaller than subterranean colonies, but a single structure can host multiple simultaneous infestations in different locations. Treatment targets the wood directly rather than the surrounding soil, which is why a professional inspection is necessary to determine the full scope before any treatment begins.
