Local Context

The Village Was Framed in Old-Growth Redwood, and Drywood Termites Found It First

Carmel-by-the-Sea grew as a village of custom cottages between the 1910s and the 1940s, and the framing that went into them was old-growth redwood and Douglas fir milled when those trees were still cheap. Hugh Comstock's storybook cottages and the many houses built in their image went up by hand, often without a stamped plan, so studs, plates and rafters land where the builder wanted them. Western drywood termites (Incisitermes minor) do not care about that. They colonize a member, stay inside it, and spread along whatever framing touches it — which in Carmel can mean an eave beam running into a hand-plastered wall with no straight path for a probe to follow.

The fog is the second half of the mechanism. Summer temperatures in the village average 58–64°F with the marine layer parked overhead most mornings, so wood inside a Carmel wall never dries the way inland framing does and never gets hot enough to stress a colony. There is no dormant season here. At the south edge of town, near the Carmel River and through Mission Fields, soil stays damp year-round and subterranean termites (Reticulitermes spp.) open a second front from below, through crawl-space piers and any wood touching grade.

The consequence is timing. In a Carmel cottage the first sign is usually a small cone of frass on a windowsill or on the floor of a closet built into a knee wall, and by then the colony has been in that member for years. Homes up the hill in Carmel Woods under the pines show it as readily as the older places inside the Golden Rectangle. Catching it at the frass stage is the difference between treating two members and tenting the whole structure.
