Coastal conditions in King County create elevated pest pressure across multiple categories. Salt air accelerates wood deterioration, creating entry points that pests exploit. High average humidity maintains moisture levels that subterranean termites need for foraging through otherwise dry seasons. Dampwood termites — which don't require soil contact — are more common in coastal Washington than inland areas. Annual inspection is particularly valuable for Lake Morton-Berrydale homeowners given these multiple climate-driven pressures.

Swarming alates are the primary mechanism for spreading termites between properties — they fly from established colonies to mate and potentially establish new colonies. Termites also spread through soil contact when ground-level wood or cellulose-containing materials allow colonies to extend into adjacent properties. Infested wood, lumber, or mulch moved between properties can also introduce termites to new locations.

Subterranean termite foraging activity slows and ceases in most climates once soil temperatures drop below approximately 50°F. However, termites don't die — they retreat deeper in the soil and resume activity when temperatures warm. In climates where soil temperatures remain above 50°F year-round, including the deep South, Gulf Coast, and warm coastal markets, termites remain active throughout winter.

Active termite damage has live workers present in galleries, and mud tubes appear moist with new construction at their edges. Inactive damage shows no live termites, mud tubes that are dry and crumble easily, and galleries that are empty. The distinction matters for treatment decisions — inactive damage still requires treatment if conditions remain favorable for reinfestation.

Drywood termites can infest wood furniture, picture frames, hardwood flooring, and structural trim without soil contact. Subterranean termites require soil moisture and are far less likely to infest furniture unless it has soil contact or is positioned in a very moist environment. Infested furniture moved from a high-pressure region can introduce drywood termites to new areas — a documented pathway for urban spread.

The most reliable early indicators are mud tubes running along foundation walls, framing, or concrete block; wood that sounds hollow when tapped; termite frass — small pellets produced by drywood species — collected near wood trim or furniture; and discarded wings near windows or door frames following a swarm. Active swarmers inside a structure indicate an established colony, not just foraging activity.

Three termite types are relevant for most U.S. homeowners: subterranean termites, which nest in soil and construct mud tubes to reach above-ground wood; drywood termites, which nest inside the wood they infest and are most common in coastal and warm-climate regions; and dampwood termites, which require wood with elevated moisture content and typically infest wood in contact with soil or affected by plumbing leaks.

Subterranean termites maintain soil contact to regulate moisture, build mud tubes for surface travel, and typically enter structures from below. Their colonies can contain several hundred thousand workers. Drywood termites live entirely within the wood they consume, produce distinctive pellets called frass, and do not need soil contact. Treatments differ significantly — drywood infestations may require localized injection or whole-structure fumigation.

Structural damage from subterranean termites rarely develops overnight, but colonies with several hundred thousand workers consume wood continuously and can cause significant damage within three to five years if untreated. Formosan termite colonies — which can exceed one million workers — are capable of severe damage within a year or two of establishment. Damage accumulates silently because it occurs inside structural members.

Termite swarming in Washington follows temperature and moisture triggers that vary by species and region. Eastern subterranean termites most commonly swarm in spring when soil temperatures warm. In warmer parts of Washington, swarms may occur from late winter through early summer. Formosan termites in Gulf Coast and tropical climates swarm in spring evenings. A licensed pest management professional can identify which species are active in your area of Washington.

Subterranean termites are attracted by cellulose in contact with soil — wood siding that reaches the foundation, form boards left in place after construction, mulch retained against the structure, and wood debris in crawl spaces. Moisture is a secondary attractant — wood softened by leaks or condensation is easier to consume and more detectable by foraging workers. Eliminating soil-to-wood contact and moisture sources reduces structural risk.

Active subterranean termite infestations are most commonly treated with liquid termiticide applications to the soil around and under the foundation, creating a treated zone that kills or repels foragers. Termite bait systems are an alternative approach that uses delayed-action toxicants carried back to the colony. Drywood termites may be treated with localized injection or whole-structure fumigation depending on infestation scope.
